I personally believe that time travel is possible. Some scientists have even said that the 4th dimension could be time travel, so I am definitely in on this game.

There are already 4 dimensions Pras... 3 space and 1 time.

Thanks for pointing that out, but what I meant to say was that time travel exists within the 4th dimension.

i think you it is possible to back in time because it has happen but impossible to go in the future

How haven't we been visited by people from the future then?

Time/Temporal police...
When the Midnighter went back in time to assasinate hitler they stopped him...
Anyway...

I don't believe time-travel is possible. Time is a man-made concept - its not regarded as (yet at least) a "Force" that can be measured.

Time itself travels - the future becomes the present - the present becomes the past - we always remain in the present.

Can Dr Who travel in time? - answer = who cares? Dr Who is sh*t...

I should get rep for both reading and attempting to comprehend that.

First, it's 3am there, go to bed.

Second, that "ultra-dense" material is dark matter.

Third, Where is Corwall in the UK.

Fourth, things can actually go faster than the speed of light. Say there's a point A and point B. Heisenberg's theory of uncertainty says that there is a minute chance that a particle can go from A to B faster than light. Thus, black holes aren't quite black. (Also event horizons...)

Fifth, If you want to laugh at someone. Say there's a gun pointed at a box with a kitty in it. The second you touch the box, the gun has a 50% chance of going off. Obviously if you open the box, the cat is either dead or alive, but what is it before you open it?

Answer:

Spoiler Alert!

Half dead!

What I read is that dark matter is matter that theoretically exists, but doesn't. I'll check that one.

Because the time machine 1. Hasn't been invented. 2. Obviously hasn't been turned on yet.

The scientist working on this(I'll edit this post when I can find his name) says that you can only travel between the times of which the machine was turned on and off. I totally support this idea.
If time, is say, 'warped' at the first of january, and then switched off on the first of february, you can't travel before the point time had begun being 'warped'.
