What If a Time Traveler From The Future Appears? | Unveiled

What If a Time Traveler From the Future Appeared? Time travel has been a mainstay of science
fiction, ever since H. G. Wells revolutionized the genre. In his novella “The Time Machine”,
a Victorian inventor visits both the past and the future. Unfortunately, while physics
MIGHT allow both forms of time travel, scientists tend to agree that it would be PHYSICALLY
impossible to achieve and/or survive. But . . . what if they were wrong? It wouldn’t
take a scientific breakthrough to prove it – just a convincing wanderer from further
on in our history. This is Unveiled, and today we’re answering
the extraordinary question; what if a time traveller from the future appeared? Are you a fiend for facts? Are you constantly
curious? Then why not subscribe to Unveiled for more clips like this one? And ring the
bell for more fascinating content! One of the biggest philosophical objections
to time travel is the grandfather paradox. If you could travel back in time, you could
presumably change the past – but that could remove the conditions that allowed you to
time travel. For example, if you killed your own grandfather before he had your mother
or father, you wouldn’t exist, and therefore COULDN’T have killed him . . . which would
mean that you WOULD exist after all . . . and COULD kill him. The paradox seems to demonstrate
that backwards time travel is logically impossible. Nonetheless, some physicists have proposed
solutions inspired by the many-worlds interpretation of quantum mechanics, that allows time travellers
to create branching timelines. Alternatively, philosopher David Lewis has suggested that
while a time traveller CAN kill his grandfather, he definitely WON’T – since he exists and
all. However we solve the paradox, a time traveller
from the future would be subject to the same rules. He MIGHT not be able to change anything.
But he might be able to tell us about what was going to happen. We just might not be
able to do anything about it! Of course, this raises the question: would
a time traveller from the future even tell us who they were? In many science-fiction
stories, it’s often imperative that the time travellers don’t let on that they have
vital information about the future. Depending on the solution to the grandfather paradox,
spilling these secrets might create a radically different timeline, or just fill us with completely
useless dread. So, if time travel is real, maybe the reason we don’t see time travellers
from the future is that they’re actually good at going under the radar. They’re not
accidentally winding up in old photographs, or letting slip the results of elections that
haven’t happened yet. After all, if time travel technology ever exists, it will surely
be closely monitored. Then again, if time travel hoaxes are anything
to go by, future time travellers might not be able to HELP themselves form spilling the
beans. One of the most famous of these hoaxes was orchestrated by “John Titor”, who
made bold claims in internet forums in the early 2000s. His predictions included a looming
nuclear war, but his credibility was destroyed when none of them came true. People now think
“John Titor” was really a Florida entertainment lawyer named Larry Haber. Today, the internet is still awash with people
claiming to be time travellers with advanced knowledge of the future. In 2017, the story
of an alleged time traveller called Noah, who kept his face and voice distorted to foil
assassination attempts, went viral. “Noah” claimed he’d travelled back from 2030, and
brought with him “evidence” of his forays even further into the future: footage of Las
Vegas in 2120, with flying cars. He predicted that Donald Trump would win a second term
in office, that we’d reach Mars by 2028, and that the President in 2030 would be someone
named Ilana Remikee. In July 2019 however, YouTuber Denis Bel claimed he was really Noah,
and that it was all a hoax masterminded by YouTube channel ApexTV. Given all these hoaxes, would we even believe
a REAL time traveller? It’s likely that their initial claims would be met with scepticism
. . . even when one or two predictions came true. After all, they could have just gotten
lucky. Even photographic and video evidence might not be taken seriously, since these
have all been faked before. How much proof would we need before we believed what we were
being told? By the time we did, would it be too late? What if John Titor’s prediction
of a nuclear war in 2004 had been true, and changing our timeline was possible . . . but
we hadn’t believed him? Of course, as more and more of a time traveller’s
predictions proved accurate, people, and even governments, would take notice. The authorities
would certainly subject a time traveller to rigorous testing and interrogation, especially
about how to build a time travel machine, since creating one would be the ultimate proof.
Even if we COULDN’T change history, governments would still probably send people back in time
for other reasons. John Titor claimed his true mission was to retrieve an IBM 5100 computer,
in order to debug computers in the future. Could real time travellers have similarly
non-obtrusive missions? Presumably ones that don’t include spending their free time posting
to internet forums. In a time travel enabled future, these agents could act more as spies,
or elite operatives, trained in science and history to achieve their objectives. Since time travel technology would undoubtedly
remain at the highest levels of government for a long time, the secret agent route makes
sense. You wouldn’t expect a CIA agent to blow the lid on whatever their current, top-secret
mission is, which is why people like that would be the best candidates to time travel. It might also be inevitable, however, that
private corporations would eventually get their hands on the same technology. Besides
opportunities for corporate espionage, this might result in time travel becoming available
to ordinary consumers. Maybe we could achieve time tourism, with time tour guides in place
to stop people from straying too far, and potentially messing with the timeline . . . again,
if that’s even possible. Space tourism is gaining more traction nowadays, but only a
hundred years ago it would be impossible to imagine that any amount of money could buy
you a trip to the Moon. Similarly, it’s hard for us to imagine now that you could
pay a lump sum to be zapped to the past, but who knows? Who would pass up the chance to
see dinosaurs? Or to witness key historical events, such as Martin Luther King’s “I
Have a Dream” speech in 1963? Historians and archeologists would have a field day,
being able to study from afar how the Egyptians really built their pyramids. Then again, time
tourists might just want to watch the world-premiere of “Star Wars” in 1977, or jump to the
1990s to get a pot of limited-edition Szechuan sauce from McDonald’s. Nostalgia is big
business, after all. It’s hard to imagine how all this would
be regulated, however. Would we need time police to monitor time travel activity? If
our actions COULD create branching timelines, would we need advanced computers to help us
determine whether a minor action might cause a butterfly effect that could irreparably
damage the future? How easy would it be to accidentally change events? And what would
be the effect? Would it just create a parallel universe, or would it break the space-time
continuum entirely? The risk of these dire consequences might not be worth the reward. Unfortunately, the most likely outcome is
that we wouldn’t believe someone was a time traveller from the future, unless they had
really hard proof. And if they weren’t trying to change history, they probably wouldn’t
let us know they were here anyway. Who knows, maybe they’re quietly among us right now
. .. And that’s what would happen if a time traveller from the future appeared. What do you think? Is there anything we missed?

  1. I'm a time traveller visiting the past right now. I just watched your video that you made 7 days ago. I could take this video and edit it differently, so does that count as effecting a recorded event from the past?? Hmmmmm

  2. If a time traveler changed anything theres no way to know . The prediction would change it and we would never know the difference

  3. There is no future to travel from. There's only NOW! Otherwise in the year googleplex, time travel would have been invented and travelers would have been here making a big mess of things..

  4. I went on a Science Field Trip to Major University when I was in High School back in 1970, we met a Scientist who was Building a "Time Machine" after his lecture and Q&A he offered us a chance to become "Volunteers" when it was built to go back in time. I was the First to Raise My Hand! It's 2019 and I'm still waiting for his call!

  5. why the fuck would we want to go see MLK's speech? Fuck that noise, there's plenty of other more interesting things to witness.

  6. Nice video.

    Since time travelers would still be bound by spacetime like we are, laws governing time travel would almost certainly have to be established by beings external to this reality. I.e. beings not bound by spacetime. That way they can monitor, police, and govern the actions of the travelers at all positions in spacetime; and at every moment in time from the beginning of the universe to its end. This prevents travelers from secretly manipulating events without the higher beings knowing.

    Also, tampering with timelines could be detrimental to more than just this reality. We don’t know what adverse effects creating new timelines would have on planes of existence we cannot see or fathom. If that’s so, beings from negatively affected planes wouldn’t like that. That’s attention we don’t need.

    The idea that there are time travelers among us is fun to think about. But, anyone who says they’re a time traveler is obviously lying to you. A broken clock is right twice per day. That’s 730 times per year. The math is mind blowing, right?! 😆

    If someone makes predictions that actually come true, remember that. They just made lucky guesses. Again, it’s still fun to think about.

  7. A time traveller’s mere present can change the flow of time and space around them and therefore change history with their mere existence even if they went into hiding due to the butterfly effect…it’s like adding an additional variable(time traveller) in a closed system(past). Hence, traveling to the past violates all laws of classical thermodynamics(might not be for quantum thermodynamics). Travel to the future is within our theoretical capability since you make use of the energy within the system to speed up the system, but travel to the past is using energy outside the system in order to reverse the flow of time. In our case, the universe is the system. Therefore, the energy required to reverse time and space must be greater than the universe.

  8. If you cant travel backward, then you cant travel forward because the guy from the future would actually be traveling backward. So with your theory, you may be able to travel to the future, but you wouldn't be able to get back and that's a problem. Unless of course, the future is awesome and in that case, you wouldn't give a shit.

  9. Not sure why anyone ever talks about orbit of planet as well as the motion of the 🌞.
    If it would be possible to move from one time to another time the position of the time traveler in the universe wouldn't change tgetfor the planet would not be there when reappear in time.

  10. Here's the question: where would you be if you could travel through time? That's right. Anywhere other than the shit hole right here right now

  11. Wasn't there some dude that predicted a buncha crap claiming he was a time traveler…he is in mental facility I think but yeah…still predicted shit

  12. I want to know the answer to practical questions. How do I make electricity using fusion power? How do I achieve interstellar flight? What do we do to solve Earth's ecological crisis? How do we solve the coming global food and water crisis?

  13. Actually there is a theory that you can only travel back to when the time machine was first turned on.

    You could only cheat this by locating an alien civilization that had one working at an earlier time.

    So seeing dinosaurs or witnessing Jesus look to be not possible.

  14. If they can travel in time then I’m sure they blend in and not be detectable to us. But they be leaving small clues and “echos” of their existence. Some events in history seem strange as they happened under odd or mysterious circumstances. Maybe time travelers are actually directing events to control the future.

  15. You cant visit moments that already happened you wouldn't be able to interact with that moment cause you weren't there to begin with

  16. If someone proved that they are from the future, at human stage right now would capture it, interrogate it, kill it and destroy it. So if there was, they would never tell and there is no good reason to come in this broken timezone.

  17. If you travelled in time, you'd also need an FTL drive, as we're travelling through space at thousands of miles per second, so the further you go in time, the further you go in distance!

  18. Time is temporal, us 4th dimensional beings simply see it as being linear and as a result have invented the idea of time. The future has already happened as well as the past. If someone did go back in time or vice versa they already would have. If someone thought about going back in time to tell us that it's real, they already have.

    That's just my own take on it. I have a degree in engineering physics so I only dabbled in theoretical physics.

  19. Ask the time traveler is did we conquer the universe..like colonising the moon,mars and other planets in our solar systems..and did we meet aliens..

  20. I've always had an idea for an experiment. Essentially, I would take a area of about 2 acres and publish its coordinates as many ways as I could for 10 years. I would have plants and maybe insects, fish and animals on it to give time travelers a reason to come come and collect DNA. I would close the area after 10 years and just let time resume as normal. That way nothing could create a paradox that would jeopardize their timeline. Things go in but never come back out.

  21. TRUMP WILL WIN BY A LANDSLIDE ( thank God) and sent Joe the pedo ( the socialist/Islamic candidates) back to looser land with “shit my pants Hillary Clinton “

  22. No, time travel is an impossibility. What's past is past and what's in the future hasn't happened yet. Time is an on going event and cannot be manipulated.

  23. I am not sure about the grandfather paradox. Once in the past you or an object become a unique arrangement of atoms, which would exist no matter what. So killing your own grand father does make you vanish and killing Shakespeare does not make the volumes of his work vanish. They exist because they once existed, even if the original process to make them no longer exists.

    I would call you and the volumes a time artifact.

    I think more of an issue is where did the physical matter of your body or the volumes of Shakespeare come from? Since the atoms your composed of also exist at the point in time you went back too. Unless through some odd aspect of physics this can not occur and the whole idea of time travel can not occur. Is matter and energy being created since the atoms of your body may now be in two places at the same time?

  24. time travel is easy… there is not forward or backwards.. the universe expands to the breaking point and goes into reverse back to the big bang and starts over… all you have to do is circle the event horizon of a back hole and wait until the universe cycles back to the date you want to go to and there you are
