Wormholes and Time Travel?

I believe that wormholes do exist, but what intrigues me the most is the idea that if you excite one end of a wormhole, but not the other, that you could theoretically move forwards or backwards in time. What are your thoughts on this?

This seems unlikely to ever actually be practical (or at least in the foreseable future).  If nothing else, it seems like you would need tremendous amounts of energy to actually do such a thing.  The theory is very interesting and good for use in TV shows, but it seems certain that no one alive today will live to see us get anywhere close to doing this.

This whole idea is very creepy to me. I don't like where my mind goes when I try to wrap it around time travel. I find it hard to see how time travel would be possible, wormhole or not, given our current understanding of time and how it works.

As I understand it, wormholes would only enable time travel in reverse, not forward- nothing can do that, even theoretically. In any case, it would be very difficult to harness their ability to do that. Other equally plausible quantum mechanics theories have suggested that one can travel to parallel universes through wormholes.

Wormholes are certainly fascinating objects. While I do believe they exist, I'm not sure what their possibilities are. One day, I'm sure science will be able to prove their existance. For now, most studies seem focused on finding wormholes rather than studying what they might do. We simply do not know where a wormhole might lead or what its properties will be. There are several theories about wormholes. One is that it could lead to time travel, but only to the past not the future. It is also theorized that these wormholes could lead to other places or even parallel universes.

The idea of going back in time makes my head hurt (would I somehow be back in time but also in the present present?).  It certainly would be fascinating to go back in time, as long as one went there as a tourist rather than as a permanent resident.

The concept of time travel in physics seems a bit different, to me, than time-travel in sci-fi.

The time-space situation of an object in a worm-hole is what gets altered, in a huge way, according to the worm-hole time-travel theory. But that doesn't mean travel backwards in time is possible. At least that's my picture of it, but I am far from an expert.

The worm-hole time travel idea seems like an exaggerated version of the example given in beginner physics courses: an astronaut leaves earth, travels at speeds near the speed of light, then returns to earth having aged much less in his travel time than the people earth have aged.

Time, in this case, is shown to be relative and time-travel is shown to be theoretically possible. But it's not like the astronaut can go back and kiss his mother when she was a baby in the crib. In concrete terms, that is still impossible.

In a purely physical way, there is no past to travel back to. It doesn't exist anymore. Neither does the future. Only the present exists, physically.

It is an interesting concept, time travel.  I don't see why it would not work, in theory.  The limiting factor has, and always will be the speed of light.  It is the fastest known speed we have in this present time.  If we could find a way to surpass it, we possibly could manipulate time.

We dont know what a paralysed body (STEPHEN HAWKING) thinks about the univese.... We dont know which principals he follow.... He only shares statement not ideas... Till we cant read his mind we cannot try to guess his extensions of mind througout the universe... But one thing i know is that the STATEMENT GIVEN BY A MASTERMIND CANNOT BE EASILY STATED AS FALSE

Wormholes, however interesting a phenomenon, cannot be used for time travel. Though there are many reasons for his but I would like to cite the major three points.

1. Its size.

Wormholes, found in the space-time fabric, are so small, that only a few atoms, or at max. a few molecules may pass through. They are microscopic. And since we have, till date, no way to enlarge it, and certainly no way to make ourselves microscopic!

2. Its paradoxial nature.

Suppose we do find, or create a wormhole big enough to squeeze through, it will be gone within seconds! A womhole, after opening, begins radiating energy and radiations, which are sucked in by the wormhole itself, and thus it gets destroyed. A good analogy would be a mic. which when starts to catch its own frequency, distorts the sound and if not stopped immediately, damages the microphone.

3. Uncertainity of destination.

If, after all ordeals we are able to create a stable wormhole, I would be the last person to step into it! Because, you never know that where a wormhole may lead you to. It can drop you at any point in space-time, and, till now, there is no way to choose or predecide the destination of a wormhole. So, for all you know, you may end up in space at the time of the big bang, or simply anywhere in space at any random time!

A wormhole can be idealized as a hole in space time. To analogize such a school of thought, imagine a long bed sheet with a mass in the middle. Although a small mass would cause the bed sheet to bulge in the middle (representing a bendage in time) - a wormhole would represent a breakage in time as we know it.


By this phenomenon, Wormholes could potentially enable time travel.

To go forward in time is most certainly a possibility according to Einstein's theory of relativity. However, to go backwards in time would almost defy the laws of physics as they are currently known to us today. Perhaps, if you believe in the concept of the multi-verse, the wormhole could take you to another universe at another point in time but that is when you get into the really confusing topic of the quantum world vs the theory of relativity which will, inevitably, lead you to String Theory in one form or another.

does that not completely state the opposite of what the Theory of Relativity tells us?

Wormholes..they are the forever-wrangling mysteries of the modern world. Einstein has stated that in order to travel back in time or forwards, we have to travel at a speed greater than the speed of light (as in the equation m=m'/(1-v^2/c^2)) where v>c. Now, in order to do this,IF by any chance we were able to achieve this, we WONT EVEN EXIST. We'll be energy formatted, not even a concrete body. So to all those Star-Trek fans and Supernatural fans alike(who think one needs just to be touched by an angel e.g. Castiel to travel back in time)..this at least will not be achieved in the near future..almost next to impossible...but hey,,for us,,IMPOSSIBLE IS NOTHING!..
