well, yes.. but the curiosity was related on how would the contraction of space have taken place..
indeed i heard about that.. but that would constitute a 'nothingness' in a sense.. from what i recall, those fluctuations are seen as constant instances of emergence and annihilation of virtual...
why not? given your analogy, by removing every trace of matter from that room, wouldn't make the room disappear.. it has the property of harboring matter, but it happens to be empty.. thus by filling it again with matter (let's say through the crack in the wall which suddenly emerged because...
all right.. now i should ask how come space would completely curl around matter making it impossible to exist on its own and also be filled with 'nothing' (only with the possibility to 'shelter' matter).. but that one i guess is a question i should put on hold until i'll gather more...
thank you for replying.. my question lied just in what you said right here (although you might have meant something else in the second phrase, since, from what you first said, gravity does come into play..):
so space is contracted indirectly by wrapping itself around matter, 'shrinking'...
thank you for confirming that..
i was only curious about the nature of gravity and it's relation with space.. that's how i found this specific thread and the common curiosity of the OP..
you said in case of contraction 'space itself will contract'.. does that mean gravity has the same...
i know my question may have been so elementary that it isn't worth answering, but still can anyone show me in the right direction? just trying to put pieces together regarding our universe like anybody else (even if it is at a lower level of understanding, since i have just begun seriously...
ok.. i understand that the concept of big crunch comes along with a certain flip of entropy in order to be valid and thus reversing its overall state from a thermodynamic point of view.. but that doesn't change the fact that time, as we perceive it, remains the same.. (we will still continue to...
i fail to see what you mean.. if the big crunch were a possibility then why would the process leading to it affect the way we perceive time? events would not roll backwards.. (i thought the first reply to dremmer's question was sarcastic, but i doubt your's is, so i had to ask..)
so what's really happening then?
does the dark energy cause the expansion of space directly or it acts on matter thus forcing space to create itself and overall seem like an expansion? (from my understanding, the former would be in consensus with the present theory, but i want to be sure..)...
