Slashdot has an interesting article referencing the possibilities of time and space travel:
“The bad news is that time does not change. Spatial velocity is given as dx/dt. Velocity in time(dt/dt) is nonsensical. As simple as that. In other words, no time travel to the past or the future, no motion in space-time, no wormholes and no hanky-panky with your great, great grandmother. There is only the changing present, aka the NOW. The good news is that distance is an illusion and we’ll be able to travel instantly from anywhere to anywhere.”
Just the kind of language to impress a hot date.
An excerpt about the concept of “space”:
The Nasty Little Truth
Physical space is given as a collection of positions. The idea is that, in order for any physical entity or property to exist, it must exist at a specific position in space. But if a position is a physical entity that exists, it too, must exist at a specific position. In other words, if space exists, where is it? As with time, one can posit a meta-space but this quickly turns into an infinite regress. The nasty little truth is that there is no such thing as space.
Interesting theories. I haven’t had time to look into the author of the site yet. But he has all kinds of crazy stuff (and of course, “crazy” is a relative term).
