Question regarding the space time and the universe.?

Question

Is it possable that we have been hear many times? If you do an experiment in a controlled enviornment you get the same results time and again. So is it possible that we have been in constant cycle for ever that will continue for ever? Lets start at a big bang, everything travels outward bringing us to where we are today as time progresses the universes momentum will slowly stop and gravity will catch up, pulling every thing back together. This would result in a big crunch, mixing matter and antimatter together, gravity continues to compact every thing together eventually matter and antimatter will reach a critical point causing another bing bang. Hear is the questioon , scince the univers is the only true controled envornment, would every thing down to the smallest particle happen the exact same way over and over?

Answer 1

Hi polohunter77

According to the results of the latest microwave sky surveys (WMAP) and the SN results it is unlikely that our universe will undergo a recollapse and bounce cycle. The universal expansion is accelerating, and this inevitably means that over time the dark energy density (which favours expansion) will increasingly dominate the mass-energy density (which produces a collapse). This means no collapse.

However it is possible that our universe spawns "daughter" universes. In a sense there could be some metaphysical "cyclic interpretation" assigned to this, but physically it doesn't wash - daughter universe scenarios leave the daughter universe causally disconnected from us.

It is certainly possible that if our universe spawned daughter universes, those daughters might mimic our own universe. It isn't necessary, but it is possible. That possibility increases as the probability space for universes increases, and if you agree with people like Max Tegmark the probability goes to 1 (certainty) when the space is infinite.


Hope this helps!

Answer 2

So far the magic Chicken has my vote. Anyway, let's assume that there is a perpetual cycle of big bang-expansion-contraction-big crunch. There is no certainty that subsequent cycles would be even remotely similar to one another. Quantum theory is inapplicable for pre-big bang events, and suggests that even the basic building blocks of matter could be forged differently within fractions of a second of each successive big bang.

It is not only highly improbable that things would happen the same way over and over again, it is also uncertain that the physical laws that govern the universe would remain consistent throughout successive cycles. The next time around, things could be MUCH different.

I'd have to say this myth is BUSTED. :)

Answer 3

the tremendous Bang theory does not say that there become not something. the tremendous Bang theory says that we are able to not use it to ascertain what would have existed earlier (if there become something). surely, the tremendous Bang theory is in holding with a supposition of what the circumstances would were like accurate this second we call the "beginning" -- that is the start of enhance. At that second (says the hypothesis), the universe become truly warm and really dense; so warm that neither count nor the forces might want to exist. Then, because the upward thrust began (and nonetheless keeps), the universe cooled and "stuff" began to condense from the organic potential: first the forces, then quarks -- that were on the on the spot stuck by using the strong pressure and became into hadrons (a.ok.a. count). etc. you're superb, that's premature to declare that there become not something "earlier". even if, it style of feels that inspite of is that element that we call time, we are able to not have any idea of it earlier that second even as the universe become on the Planck Temperature (a number of the finest temperature that is smart to us). Equations from different theories (like Relativity) seem to teach that factor did not even exist "earlier" that factor. this implies both: a) there become no "earlier", earlier the start of enhance (in which case it will be superb to assert that not something become there) or b) the idea of time become diverse, so as that there would were something earlier the... earlier. (I even do not understand what the idea of "earlier" will be if time behaves in a unique way, yet enable's in simple terms play alongside). in case you want to comprehend the universe at a huge scale, then "a" will be adequate. yet many scientists at the on the spot are seeking for brand spanking new theories that would make higher huge Bang into its own previous (or maybe replace huge Bang altogether), meaning they're searching into "b".

Answer 4

that's pretty heavy thinking. let me see if i can shift my brain. you are talking about an implosion followed be a big explosion. scientists say that it appears that the universe is expanding. to me this indicates that eventually we will be headed for some colder weather. eventually this will lead to another ice age. other scientists believe that at every ice age life evolves to another stage, more evolved. if the universe is expanding this means we are moving away from the sun. this in my opinion would negate your idea of a big crunch. some people have been regressed back in time and they believe they were some body else. this to would seem to negate the idea of things going round and round. i believe we are all part of the universe in manifest trying to figure out what every thing is and what it means.

Answer 5

The universe is accelerating at an ever faster rate. There is no indication of a big crunch. Check "branes" and "the string theory" on the net

Answer 6

Yes, it would happen the same way. Every particle is governed by a strict law, some we haven't discovered yet, the only change would be what the life forms choose and which path they take...this is what God gave us.

Answer 7

It is all 'fractals'

We are a molecule of bacteria on a larger molecule(the sun is a nucleus), the stars are other nuclei of a larger bacteria with their own molecules, the universe is a group of larger bacteria, infinity.

under your fingernail is another universe with stars, and planets and people, squeeze a zit and create another 'big bang', etc.

its all a fractal.

Answer 8

Recent research shows that the velocity of the universe is such that it will continue to expand and not be sucked back.

Answer 9

No, because of the law of inprobabilities in quantum physics. Things at quantum levels have no exact location. There are probabilities of specific locations, but also inprobabilities.

Answer 10

YAH

U GOT THAT IDEA FROM K-PAX HA?:)

IF THE SPACE-TIME MATRIX IS NOT PREDETERMINED, FOR THAT UNIVERSEE BY GOD, O WHOEVER CREATES THE UNIVERS, OF COURSE LOT OF STUFF WOULD HAPEN
DIFFERENTLY

IN A SENSE OF LIFE OR PEOPLE AND SUCH
