I have always heard that if you can go the speed of light you can time travel. But what i dont understand is that light is going the speed light all the time. So is it time traveling?

Don't believe everything you hear. 

No one knows how to time travel. 

 It depends on your point of reference, as the famous patent worker from Switzerland once determined. I believe his name was Albert. Mr Q

Only something with zero mass can travel at the speed of light.  You have mass.  The faster you go, the more massive you become and the more resistant is your inertia is to acceleration.  From the point of view of a massless photon, it traverses the entire universe instantaneously. 

The best form of time travel I could offer would be from space. If you were on the moon, in a sense you would be in the past, in regards to those of us on earth. Let me explain what I mean.

The Moon is approximately 238606 miles from earth. Divided by the speed of light @ 186,000 miles/sec, that would amount to approximately 1.3 seconds that it would take light from the moon to reach us here on earth. So if you were on the moon, and we were watching you through telescopes (which we couldn't do anyway) the reflection of your image would be 1.3 seconds in our past.

There was some talk of things like that I remember from the Apollo  Mission years. And about the astronaughts aging span because of distances traveled, etc. Don't really remember too much about it any more.

There's other weird time tricks around too. When I came back from overseas to get out of the service, I flew on a 707, most troop movements back then were by ship. Because I crossed the International Dateline going east, I landed in the US 2 hours before I left! No wonder I've been screwed up all my life  

What about particles in instantaneous communication with each other (as in quantum theory) ?  This supposedly occurs over vast distances. Doesn't this indicate something akin to time travel or at least an indication that something like teleportation might be possible?  Food for thought--

Thanks for listening!

Kevin Bozard : What you stated is correct, that being, an event occuring on the Moon, realtive to the Earth, requires time to be observed by an observer on the Earth. However, it we had a test where we could place one of a set of twins from Earth on the Moon and the other on Earth, now if the twins had clocks synchronized at the time they were placed on the moon, and were brought home to Earth after 100 Earth years, the twin on the Moon after returning with his clock would indicate his life to be longer than the twin on Earth, because of the difference in the mass of the Earth, compared to that of the Moon. The greater the Gravity the slower time propagates.  

Is it not possible that gravity has been overestimated as a serious force of nature?  Perhaps gravity is merely an illusion?

mark53 : Yes, that is true for quantum information, it looks as if the transfer of energy from a source to a destination requires relativistic time relative to matter, yet the information that determines the quantity of the transfer ( this includes all quantum information) happens instantly.There exists events, that I think are unique (this is conjecture), where two beams of gamma protons can react to produce matter, at this event the newly formed matter must complete the necesary quantum part of the energy fransfer, back to two unrelated sources, so the question is, is there an " information connection " between the two unrelated sources? Something like this must have happened at the start of the Big Bang, and it is now taking place at, or in, the objects at the center of the galaxies and quasars ,the supermassive Black Holes, White Holes, or what ever.

mark53  : The manner Mr. Einstein explained it, is to think of gravity as curving the fabric of space-time. However there is a little misunderstanding about gravity, and that being gravity curves space-time instantly, and as you may know all objects have changes in mass over time, so the gravitational influence on the curveture of space-time changes in time, and these changes in my opinion propagate at the velocity of light. In the equations, the relativistic change propagates through space-time by changing the relativistic value of both space and time.

I could talk about this subect forever, it's aboubolutely fascinating. 

I hve a feeling that GRAVITY is not what it seems to be. It seems to be more of a concept than an acual theory.  My apologies to Isaac N. !

Thanks For Allowing Me To Rant,

mark53 : We may soon know much more about gravity soon, this information could come from the LHC, Located in Europe. We need to know more about the effective process, by which mass has inertia, at this time the velocity of gravity has not been proven to the same as light C, as you may know light energy is relative to both source and destination, we do not know with certainty, if gravity reacts the same, or if it has other attributes, that may make its desired manipulation a reality.

 There is no such thing as gravity..........the earth just sucks

I heard that if you can travel faster than time you can go back to the past,but that seems impossible.
