3 Simple Ways to Time Travel (& 3 Complicated Ones)

100 Comments



Time travel can be complicated – and complicating,
so let’s ignore all the paradoxical stuff and talk about a few simple ways that you
can time travel without leaving your home. First, 1) Do nothing – you’re already traveling through
time! I mean, here you are – fifteen seconds into the future since the start of this video!
Easy, huh? The point is, we’re all always traveling forwards through time. But that’s
boring time travel. What’s interesting is time travel relative to other people. To do
that… 2) Start walking, and you’ll travel through
time relative to someone standing still! We’ve known for over a century that time and space
are really just two components of a single “spacetime”, and the faster you move, the
slower time will pass for you. If you take a walk around the block, you’ll be 3 femtoseconds
younger than your friend who stayed home. Except, in order to walk around the block,
you had to… 3) Stand up. You’re now further from the Earth,
and so gravity is a tiny bit weaker for you. Which means you’ve traveled through time relative
to your friend who’s sitting down. That’s right, more gravity makes time slow down,
too. If you stand up for a minute your feet will have aged 10 femtoseconds less than your
head. On the other hand, GPS satellites high in orbit experience less of earth’s gravity
and thus travel noticeably faster through time than we do, which is why their clocks
are calibrated to run slow. But maybe you want to time travel more than
a few femtoseconds. Get ready for your head to start spinning – I mean, the universe. 4) Because if the whole universe were spinning
really fast, general relativity predicts there would be time-loops all over the place. Moving
along one of these loops, you’d always feel like you were moving forwards in time, but
overall you’d loop around and travel back to a time and place in your own past. It’s
a little like how you can keep moving forwards on the Earth, but Earth’s curvature brings
you back to where you started. Unfortunately, our universe isn’t spinning.
Maybe it would be easier to build… 5) An infinitely long, super-dense spinning
cylinder, which would also curve space-time enough to create a time-loop. The problem,
of course, is how do you build something that’s infinite in size? Maybe you could just make
it really really really big? MmmNo. If you tried to squeeze this time machine into finite
space, you’d need negative energy – something nobody knows how to create – to make it work.
Otherwise you’d end up with a black hole. Wait, but what if instead of a black hole,
we… 6) Built a wormhole? Wormholes are hypothetical
(but not physically impossible) bridges through space-time, shortcuts that can instantaneously
connect two different places and times in our universe. If you had a wormhole you might
be able to use it to travel into the past or the future. The problem is that no-one knows how to build
a wormhole. Or, once you’ve built it, how to keep it from collapsing: as Sean Carroll
has eloquently written, “keeping wormholes open requires a form of negative energies.
Nobody knows how to make negative energies, although they occasionally slap the name “exotic
matter” on the concept and pretend it might exist.” Well that’s too bad… but as consolation,
welcome to the future! Almost three minutes have passed since the beginning of this video,
and we have personal jet-packs now!

    -_- I WANT TO GO BACK TO SEE MY DEAD CAAAAAATTTTT >:(

  3. DillyzThe1 says:

    Guys, I figured out how to time travel at home! You can travel forward a few hours with this method.
    1. Lay in bed
    2. Get a nice cup of water or milk
    3. let your legs and arms go spaghet so you fall asleep
    4. *SLEEP*
    Great job, now you've successfully traveled at least 5 or more hours into the future with this trick 😀

    closed time like curves?

    Sleeping can make u time travel

  12. Jecrenerth says:

    Scientist have been able to manipulate quantum fields to produce objects with negative mass/ exotic matter, as negative mass means negative gravity = negative energy, sooo……… yay we can make the wery long "stick" in the universe and time travel! (i mean they only made it as far as making negative mass electrons and stuff but whatever)

  13. Chenchen Zhang says:

    I watched the video with 2x play speed~ yeah~ I time traveled back for 1.5 minutes~

    I want to time travel like foreal not this bogus crap

  25. Pete Darius says:

    If you were frozen and brought back to life, let's say 100 years from now, wouldn't that be time traveling? Of course it would be in one direction only.

    I like how this video is exactly pie long.

  31. The assassin who cheated death says:

    You see time traveling through the future is an illusion as your moveing fast but time for everyone dosen't change but it is possible to go see fast you go to another dimension which may seem like you travled thought time but you didn't it's just another dimension.

  32. Agata Malecka says:

    I live on the 3 floor for first 13 years of my life I lived on 12th floor that makes me about 2 mints younger??? LOL

    How to time travel:
    Do nothing
    Walk
    Stand up

    How to time travel COOL!
    Spin the universe
    Build infinite spinning cylinder
    Build a wormhole

  36. Teddy Mene says:

    So peoples who like to sleep live 3 weeks more

  37. Charles Clarke says:

    I could be that there is only the present, no past or future is considered. Thats could mean that the present could alter the past. This could mean that matter is a probability wave until the past of the particle becomes determined in the present. Until then, there is just a sea of possible outcomes or a wave like behaviour. Once worked out, the wave like behaviour should disappear. This should affect the past as well as the present. The position and the velocity of an object cannot both be measured exactly, at the same time. The velocity is just the direction of the probability wave, all possible outcomes but the position causes the probability wave to become a single point or result. There is no way to tell the velocity and position at the same time because of this. It should be one or the other but not both.

    In this way there is no past or future that you could travel too. The future and past is just the present. The past present and the future present. The universe does not consider the past in its present and the only way to get to the future is wait until the present reaches it. Thats tonights brain fart over for now.

    You know I was stuck in this time of video cause of your annoying voice lol as it seem like it took forever for this stupid video to end 😂🤣😂🤣😂🤣😂🤣😂.

  51. Titan Hyperion says:

    So in order to become immortal all I have to do is to keep on running and I'll even surpass time itself lmao🤣🤣🤣😂😂😂😂😂🤣🤣🤣🤣🤣 wow what a genius you are😂🤣😂🤣😂🤣😂🤣

    Number 1 is my only accomplishment in life so far

  57. Zach K says:

    Woooooooooooosh

  58. Victor Silva Carmona says:

    To begin with, not why you move means that time passes slower since the seated person is on the same planet and it "rotates" at a constant speed, causing both of them to have the same reaction to time. The aging of the cells is according to the age that each one has. At the speed of the light that is in the vacuum of 3,108m / s according to Einstein's relative time stops, without time, not distance and without distance there is no movement, since according to the current laws of physics none of these variables exist without the other. If time stops you do not stop aging because your natural BIOLOGICAL organism follows its natural aging process. Time does not exist, it is the creation of the human.

  59. Kaldrin says:

    But the universe spinning relative to what ?

  60. burnt f1ames says:

    Close your eyes, count to 5 and then open them. You now traveled into the future and have no friends

  61. Ankit Gupta says:

    Time slows down when you are moving, so driving 24 thousands miles will keep your car 5 nanoseconds younger

  62. Nathan Meng says:

    I like to think sleeping can telport u a few hours into the future

  63. Anvil Evolved says:

    So I can make my younger younger than the rest of my body for absolutely no reason.

    1. Make up your own timescale so that 1 second is 1 year

  75. theguywiththecoolprofilepicture says:

    no no no, time isn't moving faster, but the speed in which events occur changes, due to variable densities of space, you move slower in thicker water. the faster you travel through water the harder it becomes, movement is slowed.

  76. Humans Are Retarded Creatures says:

    Well yes but no

    After area 51, I'll just use my time machine.

  84. David Henderson says:

    1) A man steps into his time machine, sets it for one month in the future, and the whole thing disappears. A month later the machine reappears, the man inside is dead, dehydrated and starved, with long hair and nails.
    2) A man sets his time machine for one month in the future, and disappears. A month later the machine reappears, out in outer space, in the exact location the earth was when he disappeared.
    Any questions?

  93. Tahsin Shabab says:

    Guys guys, all we need to do to time travel is to just make a time machine! Simple

  94. Supertyp says:

    Thats not correct with the walking. Because your friend who stays at home is still moving, we all are moving with the whole earth around the sun and the sun around the milkyway and the milkyway towards Andromeda and so on, so it depends in which direction you walk how fast you actually move through space-time.

  95. Icalasari says:

    Wait, how do we know the universe isn't spinning? According to our perspective, we'd be spinning with it thus making it seem still. And if it's significantly bigger than the observable section, then for all we know, going far out enough would allow us to start going, "…Oh so it's spinning"

  96. Lord man says:

    Ah yes, the most boring kind of time travel, which is the one that allows the universe at large to function
