Definitely an interesting read. I also read recently that time is the fourth dimension. And that when you travel through space, time goes at a different pace than if you are sitting on the earth. In fact, even on the International Space Station, clocks run a tiny bit slower than on earth.
I also read an interesting response to the question about the possibility of time travel. When someone suggested that in the future we will discover the mechanics of time travel, a scientist responded, saying something like, "If time travel is possible, where are the tourists from the future?"

Maybe they travel in something that looks kind of saucer-shaped and flies through the air...

It's always been considered 4th demension that I know of also - and inseperable from space. But it is relative as he says - goes back to Einstein's idea that time would slow at a speed someone on a space ship is traveling at but wouldn't notice it themselves. It's a pretty complicated issue because we know our perception of it isn't as it exits in reality.
The one that gets me is Einstein's theory that everything happens simultaneously and we just experience it as linear -- but if time is linked to space that makes sense, too because we can only experience space in immediate chunks and we are not in the same space for more than an instant so our consciousness would experience the move as time passing. Kinda like running a movie and you know what you already saw but your conscience is in one frame at a time even though the whole movie is already on tape.
Bizarre stuff to think about.
