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

Volkswagen would like you to know that every new Volkswagen comes with no-charge scheduled maintenance for the first two years or 24,000 miles.

For more on time-travel, here are some works by physicist and time-lord Sean Carroll:

There is an infinite amount of negative energy in Youtube's comment section. Time travel solved.

I was standing while watching this video, so it took seconds less time for me to watch. Suckers.

[BEEEELEEEE]

I just learned more in three minutes than I did in a whole semester of classes.

Being unconscious can mentally be considered time travel.

[mahertian]

so, I just need to stand up to make a boring class at school faster.. thanks for the tips.

I always knew I'd be a time traveller when I was older!

[evilakah]

That was the greatest car advertisement ever!!

[rhedwinex]

that's why I don't want watching videos at 3 am. I become a mad

If the universe spinning fast enough could in theory create time loops, is it possible that universe is indeed spinning, just at a rate so slow that our entire perception of eternity fits within a single loop?

the best way is to got o the future is to sleep.

guy's! I think I've discovered a way to create negative energy! What you gotta do is get your friend to buy anything. Then ruin that anything. Watch as the negative energy flows from that friend. You're welcome.

Just Walk West Through Timezones... GG You Went 1 Hour In The Past

"Who else is watching in 2016?" Not me. I reside in the year 8476. I am currently using the power of my imagination to tunnel back through time, in order to make this content visible. In my era, I am considered a linguistics specialist. Roughly only about 5000 of my people are able to speak English, or as we call it, "The Joker." P.S. You will thus discover, that by rectally consuming a daily enema comprised of coffee, Butch T peppers(pureed), and goats milk ... time travelling abilities within the imagination become ignited. Peace and Love. Tell your friends.

Things that I have concluded about wormholes:
1) You need both ends to be open(as in you can't just open a wormhole from here to there without opening one there) If this weren't true then we'd have wormholes opening up everywhere from other universes/times/places.... we don't see this happen.

2) They may be impossible... as in: Space-Time doesn't work that way

3) One side will emit radiation while the other will absorb (vise versa)... because of matter/energy can't just disappear... lets just say an object from 2015 goes to 2100... 2015 will emit a radiation of equivalent mass to that object while in 2100 the wormhole will absorb the equivalent mass of that object... this can either be bad or ok...and the energies might be drawn from the same source keeping it open idk...

These are just opinions of course

This is why i enjoy quantum mechanics and general relativity, its when u understand the physics then it start to make your head spin, not when u dont understand it ;)

[martynawezyk]

So i guess my butt is the youngest part of my body xD

[tuffdaddy]

I realized this when I was a child, I was in a friends house, I was having a lot of fun. When you're happy or having fun the time goes faster, if you're bored the time will go slower

[Patinno]

so your saying if I ran fast enough I'd be the same age and everything around me would get older

[sciencedreams]

I love the fact you took the time to calculate the relativistic factors for walking and standing up. This kind of accuracy would be very helpful if you could do an accurate version of the twins paradox, where the effects are opposing: going fast makes you younger (time is slower), but if you have to accelerate, and also accelerating when turning around you age faster (similar to being near the earth). I am told the accelerations are small corrections to the problem, but I haven't seen a reliable calculation. & as you say, this is just the convenient simple fiction that gets repeated by people who don't know more. Please, Please, make an accurate analysis video of this.
