In Einstein’s general relativity the structure of space can change but not its topology. Topology is the property of something that doesn’t change when you bend it or stretch it as long as you don’t break anything. [/b]
Well need a youtube video for this one.
I have a much easier time imagining how we would understand the big bang, even though we can’t do it yet, than I can imagine understanding consciousness.
That’s basically my point in regard to free will. How on earth can that truly be grasped.
You enter a completely new world where things aren’t at all what you’re used to.
For example, when you come here.
Right, Kids?
So when you ask me how string theory might be tested, I can tell you what’s likely to happen at accelerators or some parts of the theory that are likely to be tested.
Any actual updates on this?
As of now, string theorists have no explanation of why there are three large dimensions as well as time, and the other dimensions are microscopic. Proposals about that have been all over the map.
Someone link us to this map please.
It’s indeed surprising that replacing the elementary particle with a string leads to such a big change in things. I’m tempted to say that it has to do with the fuzziness it introduces.
Unless of course the string is just a collection of elementary particles.
