Through the Wormhole.

I don't think time travel in to the past is possible

I love complicated stuff like this because it makes my brain feel fuzzy

there's always the grandfather paradox

if you went back in time and killed your grandfather, you wouldn't exist, but if you didn't exist he wouldn't have died, thus it goes on for infinity

but there's also the thought of being on a second timeline, like there's you from the future that has already done it so you wouldn't know about it, so it would never have happened until you get to that age again.

I have seen all episodes of it, read some books of Brian Greene on the subject and I am now going to study on for astronomer.

It is possible if one manages to outspeed the light by using the warped spacetime near a black hole.
It's like curving a paper and travelling from 1 end to the other, or following the curve.
Light follows the curve and you use the end to end option, therefore going faster than the light.

Also time paradoxes; I go back in time to kill someone, he dies, he didn't exist ebfore i amde the timemachine, therefore I don't want to kill him ebcause he doesn't exist and don't make a timemachine.
Now I both killed him and let him live.
Solveable by the theory of the universe splitting with every decision made, every option to do something.
So you'd only change somethign in 1 of like 1000000000 parallel universes.

So was that the whole thing he explained with the pizza? :o

I like this show, sure.
Not only because it has Morgan Freeman in it.

I'm not an idiot, I know how it works, but time travel in to the future is only possible, as far as we know.

Holy forget.
So if two exactly duplicate planets started in exactly duplicate galaxies with only once difference being that one planet orbited the sun faster, they would be in the future compared to the other planet?

Since when does light define time? I've always wondered how going faster than the speed of light makes you go forward in time. The very fact that "the speed of light" is "the speed (distance over time) of light" suggests that it's the other way around.

[Zloff]

You'd think time would stop if you went over the speed of light considering the faster you're going the slower time goes by

I'll explain.
Spacetime has been proven of, as we all know.
So let's say that your speed (movement in space) and time are 100 together.
The more of that "Energy" you use to go forward, to increase speed, the less energy remains to propell you trough time, thus making it slower. so first you get 1 speed and 99 time. Then 20 speed and 80 time. And finally 99 speed and 1 time. 100 is the speed of light. Seeing your "energy" can't go in the minus, your speed cannot exeed 100.

Also, light is "client sided", it travels at a speed of + 300.000km/second away from you, no matter your speed.

That doesn't make sense. Time is constant.

Also, in order to get a higher speed, you can either lower the time, or raise the distance. Considering that the speed of light is not infinity, raising the distance is still possible without lowering the time.

If the speed of light was infinity, what you say would be correct, that in order to go faster than the speed of light you would need to lower time.

Also, if time is equal to zero, then it never happened.

I love this show so much!!

You're assuming that light is the limit here.

Also, how is light client sided? How is it possible that it's speed varies based on yours? If that were true then you could never outrun light.

Allow me to use one of Brian Greene's great "Simpson" examples:
Itch and scratchy hop on a train. The train is 1 mile long and drives in a straight line aroudn the earth.
Itchy in the frotn and Sratchy in the back, the train departs from a station.
Homer is in the station and Ned is on the train. A lightbuld in the exact middle goes off.
Itchy and scratchy shoot eachother when the bulb goes on.
Homer says that it was a foul duel because Itchy saw the light later than Scratchy.
Ned claims that they both saw it at the same time.
Who is right? They are both, because light is "client sided".
Well I'm not good at putting these great examples in such a small post, so it might remain confusing and unclear.

You're assuming that light is the limit here.

Also, how is light client sided? How is it possible that it's speed varies based on yours? If that were true then you could never outrun light.

That's the point.
If you were the only one to exist your time would be the only time, but all you are practically changing is your time as viewed by others. If you go faster in time, and people on earht watch you, then they don't go in time along with you. Their time is personal to them. Because light is tightly interwoved with time, as the example above and my post before that, light must result as being client sided too from logic.

-snip-

You're argument is based on the unproved statement that light defines time. Since no one is ever going to prove this statement. I'll leave, and you can discuss your show.
