Fling a Light Into the Future

""Be for Man the memory of Earth and Origin. Remember this Earth. Never forget her-- but never come back.""

- A Canticle for Leibowitz

The end is nigh, and the curtain is dropping. With no hope left, the doomed inhabitants of a world perform one final act of defiance against the coming dark: they fling a light into the future.

Whether it's their last son, a powerful artifact, weapon, or even a simple warning, they send another people in danger of similar destruction a means to recognize and hopefully avert it. Sending this shining beacon can involve an escape (space) ship, Time Travel, being put in Suspended Animation, or a Subspace Ansible of some kind. This trope is common in Speculative Fiction and Fantasy, so the means of delivery can vary considerably.

If it's part of a character's Backstory, it usually comes with a dose of The Chosen One. Sometimes, the "light" has no purpose in being sent other than in the sending; the dying world might not see themselves as able to help others, and just wants to shout its existence against the cold void of time and space.

Anime & Manga

 * Flame of Recca: Recca was born in the Warring States Era, but flung into the future (that is, our present) by a forbidden spell, to escape the annihilation of his ninja-clan at the hands of Oda Nobunaga. Unfortunately, The Rival Psycho for Hire hitched a ride...
 * Scrapped Princess:
 * Gall Force: With both sides about to wipe each other out, our heroines manage to encode a chip with a message for the future, so something of their civilization will survive. The epilogue shows astronauts from the present cycle (us) recovering the space probe. It doesn't end well.
 * Gao Gai Gar: The leader of the Green Planet sends his son, and a giant mechanical lion, to Earth to escape Zonderization, along with technological records of the weapons used to fight them inside the lion.
 * Spriggan: An advanced ancient civilization, on the eve of its destruction, leaves behind a message plate with the inscription "Protect our legacy from evil forces." The Arkham foundation and its agents, known as spriggans (or Strikers, in English) are supposed to uncover and seal away all advanced artifacts of said civilization to prevent the destruction of our own.
 * The premise of Sailor Moon with the dying Queen sending the senshi's souls forward from the utopian moon kingdom as it collapses, in order to reincarnate in the modern era so they can defeat the dark kingdom as it reawakens
 * And happens again in the Fanfic Sailor Moon 4200 after the collapse of the next utopian age.
 * The Gunmen and spiral tech in Tengen Toppa Gurren Lagann were all initially designed to fight the Anti-Spirals, and still work in that function.
 * Evangelion Unit-01. So long as a single human soul exists within it, it will stand as eternal proof that Humanity existed, even when the Sun, the Moon, and the Earth are all long gone. That's rather hopeful for a series well known for its Nightmare Fuel and musing on Existentialism.
 * In the end of Part 6 of Jo Jos Bizarre Adventure

Comicbooks

 * Baby Superman is an obvious example.
 * In the Elseworlds story Red Son, it is revealed that
 * Inverted in Final Crisis, where they send a rocket into the past, because the future is in the process of being destroyed.
 * Double Subverted in Ultimate Marvel with the Vision, who was created by a world that was about to be destroyed by the Gah Lak Tus and sent across the cosmos to visit each world that was going to be targeted by it, in order to...record that planet's cultures and leave, believing that nothing can stand against the Gah Lak Tus. But because Humans Are Special, Vision ends up fulfilling this trope and helping save the world anyway.
 * The act of driving off Gah Lak Tus actually takes a few things -- Vision's intervention and psychic contact by the X-Men among them -- but an interesting variation of this trope occurs at the end of the storyline. After finally drives off the Devourer of Worlds, Nick Fury sends Vision off, back on its journey. Except this time, rather than telling sapient species to pray to whatever god they believe in, it will be carrying schematics...
 * And a message, directly to the citizens of the universe, from resident badass Nick Fury: Human Beings can blow the crap out of ANYTHING.
 * The 616-Galactus does this when the Silver Surfer is his herald, as he knows that Surfer will warn people to escape. So long as he gets to feed, it doesn't matter to him whether there's anyone on the planet. Of course, when the Surfer actually tries to stop him...
 * In Empowered, Mind@#$%'s video gives Emp an idea on how to take down a seemingly unstoppable bad guy.
 * Played straight and subverted in the Disney series Paperinik New Adventures. Before becoming a sun (and thus effectively killing herself for her people's survival), Xadhoom recorded a copy of her mind and immense knowledge. At first it seems subverted, as she also asked her storyteller father to send a last Evronian to steal the recording so her recorded mind would kill him by giving him the key of her power but not the key to SURVIVE her power. But then is played straight by the fact the surviving Evronians will know she's still around in a way, thus getting a good reason to steer away from her people. Add that Paperinik has the recording and wants to give Xadhoom's mind a new body... Maybe that's why in the future the last Evronian says it was Paperinik to destroy his people.
 * Crisis On Infinite Earths opens with a homage to the Superman origin story. As a wall of antimatter sweeps across Earth-3, Earth-3's sole superhero, Alexander Luthor, and his wife, Lois Lane-Luthor, place their infant son Alexander, Jr., into an experimental device that will send him across the dimensional barriers to the relative safety of Earth-1.
 * Lex Jr. is an interesting example, because within that story, he is an enormous help to the safety of the multiverse. However,.

Film
""I won't live to report this, but someone has to know.""
 * The titular hero of Willow does this to The Chosen One in the climax, sending her somewhere "where evil cannot touch her!"
 * Both subverted and Lampshaded in Children of Men, humanity has become sterile and thus will become extinct in half a century. The protagonist, Theo, visits his brother who is dedicated to preserve works of art and he asks him why he does that, if in 70 years there will be no one left to see those works.
 * The book the film is based on mentions that a lot of art and cultural works are being sealed in vaults to preserve them for just this purpose: the tiny chance that something else might one day exist to see that human civilisation was here is better than just letting them crumble.
 * The express purpose of the Miranda Recording in Serenity:


 * Alien. The unnamed Pilot of the alien spacecraft left a warning signal; unfortunately it only succeeds in attracting people to the derelict.
 * John Carpenter's Prince of Darkness. Inverted.
 * In Iron Man 2,
 * Both Megamind and his arch-nemesis Metro Man have the same origin story up to the point of them crash-landing on Earth. Their planets were about to be sucked into a black hole, so their parents sent their infants away.
 * Mission to Mars reveals that.

Literature

 * A species doomed to extinction by a in Greg Egan's Incandescence takes a radical approach to Fling A Light Into The Future:.
 * Similarly in Olaf Stapledon's classic Last and First Men, the Last Men, realizing that changes in solar radiation will destroy all life in the solar system, launch a gigantic project to fire the "basic germs of life" into interstellar space, so that one day they will reach a planet and the cycle of life will begin anew.
 * Which is brutally subverted in the sequel Last Men in London when they realize that their method of distribution was actually destroying the seeds it was supposed to disseminate. And by the time they realized this, their civilization was too poisoned by radiation to fix the problem.
 * Also, Arthur C. Clarke (Creator)'s The Light of Other Days had a similar plot point - an intelligent species evolved on Earth several billion years ago, but was about to be destroyed by an asteroid impact that they could see coming but couldn't stop, so they basically filled the earth with bacteria so that at least the basic building blocks of life would survive.
 * Pastwatch the Redemption of Christopher Columbus by Orson Scott Card has two different timelines (the second created by the first) resorting to time travel in order to avert the end of the world by changing the course of history hundreds of years earlier.
 * This requires a little bit more clarification. There are actually three timelines involved. The original timeline creating the second timeline. This second timeline
 * What was.
 * Also, in case you're wondering why the original timeline had to be changed was because.
 * One person from the second time-line
 * In A Canticle for Leibowitz, the world is destroyed by a second nuclear war at the end. However, this time humanity will survive because the Church has worked hard to send out a ship to colonize other planets.
 * In a Stephen Baxter's short story The Quagma Datum, a species in the very early universe creates a lithium 7 nova as a signal to the later universe that they were there.
 * And in Manifold Space, a coalition of aliens.
 * This was the avowed intent of Winston's diary in 1984, at least at one point. Of course, he knew it wouldn't work, and mostly did it for catharsis. That didn't work either.
 * Alastair Reynolds Revelation Space series has this, in the first book . In Redemption Ark,.
 * The Xunca in Alan Dean Foster's Humanx Commonwealth universe did a version of this. They were unable to find a way to confront a galaxy-devouring Ultimate Evil, and so they fled into Another Dimension, but they left behind an enormously powerful weapon that, half a billion years later, a new sentient species might find and possibly use against it.
 * Arthur C. Clarke (Creator)'s The Star
 * Also in Clarke's second A Time Odyssey book, Sunstorm, where a dying alien civilization (only few peoples left) and 2 Human-made AI decide to use their last strength to send the third AI back to Earth to give humans more information on the Firstborn.
 * Inverted in the Fighting Fantasy book Black Vein Prophecy:.
 * Essentially the reason for the titular Foundation in Isaac Asimov's series of that name, both in actual fact and the cover story... except, instead of flinging a light of knowledge and possibility into the future for others, it's for humanity itself.
 * is revealed to be that in the later books of the Sword of Truth series.
 * Prophecy in general, thought YMMV on that one. In fact, in-universe YMMV.
 * Several of the tests that Richard has to face. Justified, since the Wizards from the Great War knew that Subtractive Magic was locked away from future generations in the Temple of the Winds before War Wizards started to die out.
 * There was a short story called Last Contact where the Big Rip happens much earlier than expected, and there's a throwaway line about how they're discovering new alien stars daily, because those aliens are doing very noisy artificial things (like throwing a huge pile of exotic atoms into their sun) simply as a "The universe is ending, but I'm here!"
 * This is the direct origin story of one of the Sufficiently Advanced Aliens of Perry Rhodan. A highly advanced species faced with a slow decline into extinction embarks on a long-term project to send all of their accumulated knowledge out into the universe in a self-sustaining "Prior Wave". It takes long years and much difficulty until the wave is finally sent, and it travels through the universe for rather longer, touching the ancestors of at least one known civilization along the way...until it gets absorbed, purely by chance, by a cloud of cosmic dust that is just about to collapse and form a solar system. Fast forward to the actual formation of the planets, and one of them in the new star's habitable zone is featuring a super-intelligent crystal shell englobing much of it (and eventually its atmosphere) -- the future Empress of Therm. (A poignant scene shows how the last survivors of an expedition launched by the Empress much later, after intelligent organic life has finally evolved on her world and she's gone about building the actual empire she takes her name from, discover that planet of origin...a dead world with no signs of the original civilization left at all. Even the ruins have long since crumbled into dust.)
 * A version of this trope, less dire when it was enacted, happened in the Star Wars Expanded Universe. Alderaan's pacifism is mentioned to be a relatively new development. When it became global, some of their weaponry was auctioned off, some was melted down and repurposed... and two were set aside, computer-controlled and kept in local space. The Rebellion found one not long after the world was destroyed. In the X Wing Series, one came to Rogue Squadron's rescue.
 * In Martha Wells' City of Bones, the Krismen (humanoid marsupials resistant to poison, drought, and desert sun) were created so that at least something mostly human would be able to survive in the wasteland consuming the known world. (And then it turned out that normal humans could live on the fringes of it just fine, so now the Krismen are a hated underclass whenever they leave the desert to do business in the cities.)
 * The Star Trek Expanded Universe novel Eyes of the Beholders featured the Enterprise encountering an art museum built by a now-extinct race for this purpose.
 * This happens to Luke, Leia, Yoda, Obi-Wan, and pretty much the whole proto-rebellion at the end of Revenge of the Sith. Obi-wan and Yoda go into exile, the twins are sent to adoptive families in secret, and the rebellious senators vote FOR the newly christened emperor.
 * The Book of Mormon purports to be collection of prophetic writings abridged by Mormon, one of the last of a persecuted line of Christians in the ancient Americas. Mormon wrote this abridgement on golden plates that would be hidden in a hillside for centuries, in hopes that the fall of his people would serve as a warning to future inhabitants of the Americas.

Live-Action TV

 * Babylon 4. Was set up to be this particular trope, but turns into "Fling a Light into the Past", or almost a Kyle Reese sort of thing.
 * Though they weren't actually going extinct, some alien dissidents preserved a collection of their race's greatest artistic masterpieces when their government declared art to be an illegal waste of resources. This precious collection was later salvaged by the Excalibur's crew on Crusade.
 * In the prequel movie In the Beginning Mankind does this: when Earth is about to be hit by the unstoppable Minbari, hundreds of civilians are evaquated as Earthforce and any ship capable of fighting try and buy time fighting the Minbari, so that Mankind will still survive.
 * The tearjerkingly brilliant "The Inner Light", an episode of Star Trek the Next Generation commonly seen as one of the best, tells the story of an alien race doomed by instability in their sun who send out a space probe that finds Picard and forces him to hallucinate living a lifetime among their final generations before the end, and thus ensures that their species will at least be remembered. It affected Picard and no other crew member. The life he lived involved getting married, having a family, and other things he's never made time for - taking it from a disturbing experience to something he sees as a gift.
 * But brutally subverted in Star Trek Voyager's "Course: Oblivion", in which create a log capsule that will survive after them, and their attempt to launch it fails, destroying it. The ship disintegrates just beyond 's sensor range.
 * There's also an episode with a mysterious monument that commemorates a slaughter by forcing everyone in its proximity to become a participant in the massacre.
 * The final message from a never-seen culture to "Beware The Destroyers" is the only reason Stargate SG-1 lasted more than a season.
 * Then they did it again with the Asgard.
 * And the Ashenn storyline involved flinging a light into the past. They like this one.
 * In the recent Battlestar Galactica Reimagined,
 * The Andromeda Ascendant on Gene Roddenberry's Andromeda, except that it was thrown into the future by accident.
 * Buck Rogers. Although it was completely an accident. And the fact that although the civilization he knew was destroyed, a brand new society took its place.
 * The revival of The Outer Limits gave us the episode "The Music of the Spheres". The world is bombarded by alien broadcasts that anyone under the age of 21 or so believe to be the most beautiful music they've ever heard. When the broadcasts prove addictive and cause those who listen to them to mutate, the world governments declare martial law, until scientists succeed in decoding the message. The signals originated on a world whose sun had turned ultraviolet 40 years ago. The signal warned that Earth's sun was about to undergo a similar change, and that the broadcasts would genetically alter those who heard them into a new golden-skinned form that could survive under the new sun. Oops.
 * Fortunately, it had a rare good ending with no twist involved:
 * The basis of the plot in Power Rangers Wild Force. The Animarians were losing a war against the Orgs. Both sides were mostly destroyed the Orgs leaving behind some Sealed Evil in A Can, and the Animarians leaving behind a Floating Continent, a princess in stasis, and a few giant robot animals scattered around.
 * Terra Nova is built on this trope. Mankind in the future (2149) is doomed as they have destroyed their ecosystem, so they send people through a "time fracture" into the past, to try to save the human race and "start over."
 * Jikuu Senshi Spielban's heroes serve this purpose, as they were sent to Earth  after their civilization was attacked.
 * In Supernatural Sam and Dean have to go to the past and retrieve the ashes of a Phoenix to destroy Eve. They succeed in killing the Phoenix but can't get to the ashes in time due to their limited time frame. Samuel Colt, yes that Samuel Colt, sends the ashes to them via Western Union with instructions to wait like 100 years so that they get them in the present. It's not technically the future but it was Samuel Colt's future.
 * Stargate SG-1: An Alternate Universe SGC in "There But For the Grace of God" received a message from an unknown culture that was about to be wiped out by the Goa'uld. It gave them the gate coordinates from which the Goa'uld launched their attack. Unfortunately this SGC never learned how to speak Goa'uld and the warning went untranslated until a quantum mirror landed the prime universe's Daniel Jackson in that one. At which point it was too late for that Earth because the Goa'uld were already there. Luckily, Daniel was able to return to his own universe with the gate coordinates, and SG-1 subsequently defied orders to save the planet from Apophis's invasion.

Tabletop Games

 * Inverted in a profoundly dark and disturbing way by the Illithid race in Dungeons and Dragons (at least before 4th Edition). The Mind Flayers were - or will be - the overlords of the multiverse at the literal end of time, when most if not all the stars have burnt out. But after facing defeat at the hands of a trans-planar rebellion (not that there's much to fight over at this point), the Illithids sacrificed unbelievable numbers of their Elder Brains to create a psionic maelstrom that sent the surviving members of their race into the distant past - that is, shortly before the D&D setting. This way they can get a head start on forging their empire while avoiding that pesky slave uprising altogether. It also explains their tremendous egos; after all, they know their victory is inevitable.
 * One more disturbing note about the Illithids - it's possible for characters to take feats representing having monstruous non-human ancestors, like a bit of dragon blood in your family tree or something. If you apply them to the Illithids, it doesn't mean you have an inhuman ancestor, it means that the squid-faced, brain-eating monsters with the parasitic life cycle are your descendants.

Videogames
"Pravin Lal: To the people of that regime…to see the Unity catapult itself into the night sky…and to think, in the pain, the poverty, the death and sickness all around, that perhaps, in forty years time...hope. For humanity.
 * Subverted in Anachronox, the light is flung into the past.
 * And the guys doing it are dicks.
 * The Defiants in Rift have a similar setup: The hero is sent from the Bad Future to the past where the odds against Regulos were much more favorable.
 * Likewise, the premise of the Serious Sam series is that the last surviving human is sent back several millenia in time so he can assassinate the galactic Evil Overlord Mental before he can destroy Earth.
 * Sid Meier's Alpha Centauri treats the UNS Unity as this. The novelization Journey to Centauri makes that chillingly clear; right after the future faction leaders realize they were a light flung into the future, a short list of major networks and facilities are listed as "offline" or in various states of error.

Deidre Skye: So they fired us off, a wild firecracker into the sky, and they hoped."


 * In Mass Effect,.
 * Also, the beacon from the beginning of the game served a similar purpose, though it was not intentional.
 * It's not a coincidence "Vigil's Theme" is the menu music for Mass Effect.
 * In Mass Effect 3, with the Reapers invading and galactic extinction a possibility, Liara makes a point of documenting the struggle and leaving vital information behind for future races in case they don't make it.
 * Also from ME3, we have
 * We also have Javik, the last Prothean. A soldier during the last days of the Prothean Empire, whose plan was to go into cryosleep with hundreds of thousands of others, so that they could rebuild the empire in the future. Unfortunately, several Protheans on the colony end up indoctrinated and sabotage the defenses. When Javik is about to be frozen, the facility's VI called Victory informs him that there's not enough power for all the occupied pods to last tens of thousands of years. Following its programming, Victory shuts off all the pods but Javik's despite the latter's protests. Victory tells Javik to tell future races of the Protheans. However, Javik has other plans - he will be an avatar of vengeance against the.
 * Additionally, there's left behind on  by the Protheans to aid the  in becoming the dominant species in the next cycle.
 * Halo. The namesake of the series Also, humans
 * It's the whole premise of Halo: Reach, as you already know that the entire planet will be destroyed with barely any survivors, but that one ship makes it out with the coordinates to reach the first Halo. The last parts of the game are all about retrieving the data from an ancient ruin before it's overrun by enemies and take it to the last remaining warship in the hope that it will find something at the coordinates to help save humanity from total extinction. At that points it seems as if you're the last handful of humans still alive on the planet and when the Autumn takes off, you stay behind to cover their escape, watching it disappear into the sky.
 * The Framing Story of the Assassin's Creed series is that of a modern day Mega Corp recruiting people to relive their Genetic Memory via a device called the Animus in order to locate powerful artifacts left behind by Those Who Came Before with the objective of using them to Take Over the World. Well, it turns out that the ancient species in question knew this would happen and left behind messages designed to be seen by the people communing with their ancestors via the Animus. This is all being done in order to avert a recurrence of the same catastrophe that destroyed their First Civilization. The Assassins themselves worked to conceal the artifacts of the First Civilization in order to prevent them from being recovered and used by the Templars; it is therefore up to their modern-day descendants to recover and use said artifacts for their intended purpose.
 * In Free Space, the Ancients' Apocalyptic Log is found near the end of the first war and is pivotal to saving Earth and defeating the Shivans.
 * The Soul Cube in Doom 3.
 * Backstory of the Shivans in City of Heroes. An alien planet destroyed by Shiva sent a probe to Earth to warn it that it was the next target. Humanity found this, deciphered the language, found they had only a little while before Shiva would destroy them, and blew Shiva up. Unfortunately, the fragments landed on an island a bit close to home, and are trying to reform themselves. Hey, they're my favorite villain group, so I know a bit.
 * In Starcraft II,
 * Dr. Light created Mega Man X in hopes that he would help create a world of peace.
 * In the Flash game Cellcraft, a race of advanced platypus-like people discover that an inescapable cataclysm will wipe out all life on their planet. With no means to escape their eventual destruction, they breed microbes (the premise of the game) tough enough to survive even the most hostile conditions that are still capable of supporting life and send them to another planet -- that planet being Earth. This is apparently the origin of platypi on Earth and handily explains why they are so strange -- they are aliens.
 * The Vault program is this in the Fallout universe. At least, the handful of control vaults were. Specifically, the Garden of Eden Creation Kit (G.E.C.K.) that came with most Vaults was meant to give the survivors of the nuclear apocalypse the ability to rebuild, even when the world as they knew it was gone.
 * In WURM Journey to The Center of The Earth, while searching for your missing comrades, you dig too deep and discover a beacon from a long-lost civilization.
 * In Homeworld the ancient Hiigaran Exiles, realizing they were being forced to leave their city about to be buried in sand and lose their technology, left into it the Guidestone to tell their descendants the way for their ancestral Homeworld and an hyperspace module to reach it.

Webcomics

 * In Homestuck: rips her incomplete walkthrough out of the internet and seals it in the Furthest Ring so that other SBURB players can read it. In an inversion, the person to read it turns out to be
 * Nedroid: Beartato's parents put him in a rocket before their planet was destroyed. Reginald, in a similar rocket, was sent up because his father had stuff to do.

Western Animation

 * Princess Tekla in Shadow Raiders was a Pursued Protagonist warning of the coming of the Beast planet.
 * In the old 60s Spider-Man cartoon, the planet of Gorth launched its library into space to avoid destruction by a giant lobster from Dementia 5.
 * Subverted and parodied in Sealab 2021, where the crew leave a capsule for future generations to find. It contains toxic gas and a note reading "Eat it, future bastards!"
 * An inversion of this was the premise of Samurai Jack. Aku, the Big Bad, was not strong enough to defeat the titular hero, so instead flings him into the future. Jack arrives in an era where Aku is the unquestioned ruler.
 * The origin story plays it straight. When Aku attacked Jack's homeland, Jack was safely evacuated and spent the next 20 years traveling the world and training. He returned too late to save his people, but could have avenged them if the series had not been cut short.
 * An episode of The Batman called "Artifacts", is set 1000 years into the future. Mr. Freeze, who is immortal, goes on a rampage with no Batman to stop him. Archeologists find the Batcave, where Batman left instructions on how to beat Freeze, etched in titanium, knowing his computers would eventually become obsolete and incompatible with the technology of the future.
 * In "Twenty Years To Midnight", Jonas Sr. receives a message that the fate of the universe depends on him building a machine and getting it to Times Square in 20 years. He dies before then but leaves a message to his son with all the details and where he hid the pieces. It's one of the few times Rusty actually does something good successfully (despite several obstacles, obviously).

Real Life
"...and even if, which I do not for a moment believe, this Island or a large part of it were subjugated and starving, then our Empire beyond the seas, armed and guarded by the British Fleet, would carry on the struggle, until, in God's good time, the New World, with all its power and might, steps forth to the rescue and the liberation of the Old."
 * The human civilization itself! Even if Earth (and every person on it) were obliterated tomorrow, our old radio waves would continue to travel in the interstellar void forever.
 * The Other Wiki has an official policy, accessible here, for preserving its contents in case of The End of the World As We Know It.
 * According to the History Channel's 'Life After People' Mount Rushmore will probably remain recognizable long enough for other species to develop sapience and recognize it as an unnatural structure. Which means Teddy Roosevelt will never die.
 * As an inversion of sorts, the Waste Isolation Pilot Plant project is struggling to find a way to inform future generations not to mess with our radioactive waste.
 * Seedbanks.
 * Several cases during World War II. Of course, most of them, with the exception of the first example are more of hoping that their allies will rescue them in the future, rather than just sending the light off to help others.
 * Several inmates at Nazi concentration camps wrote and buried diaries to let the world know what happened.
 * The history and life of the Warsaw Ghetto was extensively documented by Jewish scholars and buried. Most but not all of the document caches have been recovered.
 * Winston Churchill:

"Take up our quarrel with the foe: / To you from failing hands we throw / The torch; be yours to hold it high."
 * As Poland fell, they sent off to the UK their work on breaking the German codes. This has been portrayed as a dying man flinging his sword to his ally, so they can continue the fight.
 * Several of The Long Now Foundation's projects are about this. They include a clock to run for ten millenia and an effort to preserve languages that are likely to become extinct.
 * Some high schools have buried time capsules, where they get a container, fill it with stuff from their year and bury it. Decades later, at a school reunion or something, they dig it up and see what everyone put in there to reminisce about their teen years.
 * From the famous World War One poem In Flanders Fields:


 * A total of five space probes have been sent out, or are on their way out, of the solar system (Pioneers 10 and 11, Voyagers 1 and 2, and New Horizons). On them contains information about both the location in space, as well as when, they originate from. A number of scientists think that they may one day be picked up by some other intelligence and will tell them we were here, once.
 * Or a Klingon will blow it up because he's bored.
 * Or an evil robot will use the information to travel through time and try to wipe us out before we evolve
 * On a smaller scale, this is the purpose of reproduction. Every living organism eventually dies. Its genetic material and heritage is carried by its offspring.
