Time travel and your opinions?

Question

For believers in time travel, I would like to hear what are your opinions on how time travel might eventually be possible. Please be really original about your ideas. Thank you.

Answer 1

unless you can break the laws of physics and manage to go faster than the speed of light, its not going to happen.

Answer 2

impossible

Answer 3

Time travel may or may not be possible. It's reared its head in some modern physics interpretations however, all of which are controversial and none of which are taken very seriously at the time being.

It starts with the question, "How do I describe a particle moving forward in space but backwards in time?" You can't just say -v, because -v is just -d/t (distance/time) and that's just a particle moving backwards in space but still forward in time, the opposite of what we're trying to do. (Same problem with vector calculus, slap a negative sign on it and you just get a backwards space vector).

No, the way you write a particle moving forward in space but backwards in time is by using the complex plane -- you would say vi, where i is the imaginary number sqrt(-1).

Turns out that this method of using the imaginary number in any equation that involves time can be interpreted as something moving backwards in time. That leads me to the most interesting part: every time we solve the Schroedinger equation we actually get two answers, one with real numbers and one with complex numbers (complex numbers being those that involve imaginary numbers, i). The imaginary solution is simply thrown out.

Some are starting to assert that we shouldn't throw it out and that it represents something real that is moving backwards in time.

Ultimately this doesn't answer your question but it's interesting to think about. It's probably a bad interpretation as far as philosophy of science goes but it's brain tickling nonetheless.

Answer 4

Well, to travel into the future all you really need to do is hibernate or cryogenically freeze yourself.

Into the past is another story.

Our current understanding of the universe doesn't allow for travel into the past,  because the past doesn't actually exist in any way.

It did exist, but it doesn't anymore .. that's what makes it the past.

But that doesn't mean it's not possible.

There's no telling what we might discover about the way things work.

Answer 5

Time travel is indeed possible & it all depends on the distance & energy or force (I use the term "eniforce") used to cover that distance. Using my time equation : Time = Distance divided by Eniforce, you only have to substitute values to see that time travel can & does exist. I am sorry I cannot provide anymore details here as it is a "very" complex problem but I have tried to answer your excellent question the best I can !

Answer 6

i think that light holds the key to time travel. light has been proven to warp space time more than matter, therefore light has more gravity. now here's my idea:

we have these special lasers that can actually be used to bend light. if we made a square using 4 of these lasers, and stack multiple squares ontop of each other, but bend the angles ever so slightly, we would make a pathway for light to take that would bend space so much it would make a rip in space-time. but just one of those squares would cause america to go bankrupt!

Answer 7

...read some of the articles from Carl Sagan about "time travel"...  to play "beat the clock" it's going to take a very very "fast" vehicle...   really fast...  I doubt even Superman can kick it up that fast...
