Time travel, as you may normally think of it, is impossible.. but something even cooler may be...

I was looking at this image (http://antwrp.gsfc.nasa.gov/apod/ap080723.html) this morning and started thinking about its quote. It said that a long time ago water could have fallen off from these cliffs and could actually have been the force that formed these impressive precipices.

Then I realized that the whole “travel in time” idea is impossible. This is why:
People who claim that time travel believe can be so if they can travel faster than the speed of light. However, what I think would happen if you were able to travel faster than light is that you would be able to catch the IMAGE of the events that have taken place in the past. Just as it takes 8 minutes for light to reach earth from the sun; we say that we are now looking at what happened on the sun 8 minutes ago. If we could travel faster than light, our starting point was the sun, and we headed toward earth, all we would achieve is reaching earth BEFORE the image of the sun at the time we left was able to get to earth. The event, no matter how fast we traveled, would have already happened; and there is nothing we could do to go back before that event.

So what I was thinking was that if we could travel much, much faster than light we would be able to SEE what happened in the past. We could determine if lava, water, or Diet coke was the culprit for such wonderful canyons in mars. Perhaps this would be an even better power than actual time travel since we would not have to worry about the whole time and “killing your own parents” paradox!
