Yeah, quantum physics/mechanics is pretty amazing, but I personally think they went a little to far with parts of the string theory. The idea that all matter is at it's root made of strings vibrating in different shapes makes sense to me, and can explain allot about how sub atomic particles interact with each other and why that has nothing to do with why larger particles (bodies such as stars, planets, galaxies, black holes) don't play by the same rules. It seems plausible, but when they start talking about an infinite number of parallel universes or states of being, I think they are trying to blow smoke up "somewhere" to get more funding or something... or maybe my little brain just can't follow what they are trying to say, but I doubt it.
I really do understand what they mean, I just don't agree with that part if it- they make some very large leaps.
Einstein and most other great thinkers back then just disregarded what happens on a subatomic level, at least strings start to attempt to explain it. Stephen Hawking at least try to combine quantum mechanics and the Newton's laws so they could both exist, and both be correct.. which goes to the next question..
"I find this extremely hard to define... If you base it around maths, then:
0 (divided by) infinity = any number --- thus meaning that infinty would be a definate value, just an unknown definate value, so not truly infinite as the definition of the word may suggest.
Any number (divided by) 0 = infinty
(not 0, as the common mis-conception would suggest)
and yet - any number (divided by) infinity = infinity (seems like even maths can contradict iteself!!!)"
Hawking radiation.
This is a quick description-
"Virtual particle pairs are constantly being created near the horizon of the black hole, as they are everywhere. Normally, they are created as a particle-antiparticle pair and they quickly annihilate each other. But near the horizon of a black hole, it's possible for one to fall in before the annihilation can happen, in which case the other one escapes as Hawking radiation."
In fact this argument also does not correspond in any clear way to the actual computation..
So this is another "fact" that really cannot be explained through math- yet
Ok, so your mathematical description of infinity is trying to do the same thing- sometimes you can't describe a theory through math.
My personal view? As soon as you do this--
"0 (divided by) infinity = any number --- thus meaning that infinty would be a definate value, just an unknown definate value, so not truly infinite as the definition of the word may suggest."
You are already off track. To me, infinity is envelopes everything- so once you start trying to describe it mathmatically, you can't add "another one" into the equation. There is only one infinity- any other number cannot exist outside of it, it is already part of it if infinity truly is infinity by the definition we use.
Kinda off topic I guess, but anyway...
Another thing that's hard to comprehend about infinity is the part about "no beginning"- I can fathom no ending, you just keep going and going and going, without end. I think we can comprehend this because we have a beginning, we were born, and before that we didn't exist yet.
But start trying to comprehend no beginning- It's very difficult to even imagine something having no beginning, it just doesn't make sense.
Where did it come form? Uhh, it's always been there- huh? who made it? -uhh, no one. Well how did it come to be? It didn't, it was already there. Your mind runs in circles, It's crazy.
Try explaining that with math.
ok, I'll quit babbleing now..
