Is time travel possible?

[TheEasternMovieCritic]

 First of all, here's a paradox: If you go back in time and you kill your father before you were born, you will no longer exist. But if you do not exist, that means that you didn't go back in time to kill your father.

   Anyways, there are different theories about the structure of the time-space continuum and how it can be modified. The most popular heory states that in order to mend the time-space continuum, we have to exceed the speed of light. Other thories involve black holes and other anti-matter thingies which are close to impossible to use. I personally think that time travel is not possible and even i it would be, using it would mean a lot of risks.

   What are your thoughts?

Well, going past the speed of light will only freeze time, but in essence cannot make you go back or forth in it. Like you mentioned Black Holes and other anti-matter things may be able to break the the time space continuum, but we can't necessarily control them, so it would be best to find out if the universe has any other "holes" in time!

Ofcourse it is, we just need to re invent the Flux Capacitor and place it in a De Lorean

Yeah.  88 mph oughta do it!  Who said anything about the speed of light?

[Ben_Hayden]

chuck norris can time travel by running 88 mph!

1.21 gigawatts???

I'd say time travel the way we see in movies is physically impossible, but the speed of time changes and distorts throughout the universe with gravity.

Going at the speed of light wouldn't freeze time at all. Light isn't instant at all. When you look at the night sky and see the stars, you're seeing the stars the way they were thousands to millions of years ago. If aliens from another solar system invented a telescope so powerful they could see earth up close, they'd see dinosaurs.

Time can distort though. Mathematically speaking a 'worm hole', a black hole and white hole together, if something entered one and exited the other, it would be observed to exit the white hole before entering the black hole, so you'd see two of them. The one which appears from the white hole couldn't interact with the one which is entering the black hole though, because there'd only be one set of particles making up this item.

Something like that.

 Correct! Even when we look at the sun, we see the sun which was 8 minutes ago.
 
 Some say that the space-tme continuum has the shape of a horizontal  arch.

  ------------------\
                             \
                             /
     --------------- /
 
 (well, the lines should be like a semi-circle)

  And by exceeding lightspeed we can get from the part we are now to the other. IOW, we can slice through that arch. Of course, nobody has tried this...exept for Doctor Emmet Brown...
