They all studied under Hawking, so ask him, I'm sure he'd know, no question about that. But time travel is a very touchy subject as there is so much behind it: Alternate realities, parallel dimensions, ect. It's weird to the point that technically if we ever found out how to travel backwards in time, we'd cease to exist on this reality and yaddah yaddah. I watch too much Star Trek. lol
I thought almost everything Hawking said is now believed to be wrong.
Time is a concept made by man. To say that the 4th dimension is time is wrong because dimensions existed long before man has.
I have often pondered what pure nothingness is. Nothing is nothing, even though in a world of nothing, nothing would mean nothing, but then again nothing is nothing and so there is no meaning.Gah, doesn't make sense :(Indeed.And wouldn't the first dimension be infinitely small?
It's also impossible for us to think of a color that cannot be made with mixes of red blue and yellow.
This is why just on Tuesday, Obama awarded him with the highest civilian medal in existence. If he awarded that for being wrong...forget I'd have a million of them.
The only thing I've learned from this topic is that time is the fourth dimension.
LOL YOU loving DUMBASSLOOOOOOOOOOOOOOLlol.
I dunno I was watching science channel and they were talking about how most scientists don't agree with his ideas on blackholes. The show had Michio Kaku in it so im assuming it had some educational merit.
