is the reason the universe is expanding because another universe is attracting it. infinite amount of them?

Question

its my inclination to think the universe is not a singuler infinite entity, that infinity is occupied by universies. imagine the lights on a christmas tree , every light a universe, now forget the tree shape, its like a infinite blanket in every direction, each universe having perhaps a spiral gravity affect on others, thus explaining the epansion of our universe.

Answer 1

interesting theory, but I don't think so.

Here is a website that links to many others all of which explain various aspects of 'M' theory. There may be infinite numbers of universes according to that now popular theory. But beware because the underpinnings of the M theory are very fragile and may, in fact, be disappearing into an alternate universe as you read........... Kalabi- Yau to ya'll.

Expansion, contraction, acceleration, inflation? All as yet unexplained except for loose conjectures. Consider the Big Bang alone. An explosion, eh? Where? Into what? Why? If the mass that exploded had any physical size at all where within that mass did the explosion start? Wouldn't any one starting point other than the exact center create faster acceleration and less mass and slower accelration and more mass in various vectors if there is no resisitance anywhere? Was that mass which 'exploded' a sphere? A cube? A duodecadon? An egg? Maybe 'everything' within 'our' physical universe coalesced from an 'energy' that cooled (due to what), creating gravity as a biproduct? Maybe gravity just 'became'. It somewhat amuses me to ponder that stars developed because gravity caused 'star dust', er, gases, to accumulate and develope into stars. Oh, yea? Just what caused the initial teenee, tiny bit of gravity to exist at some coordinate in time space? What is this force anyhow? We can describe its attributes and know what physical laws it directs but we don't understand it basics like how it acts instantaneously over large distances and simultaneously in many directions. It is because it is! We only report our observations. From a philosophical viewpoint we understand that which we observe currently rather well we think, but we are as far removed from understanding the beginning, Big Bang or whatever, as the ancient Greeks with there ether, fire, wind, water, earth and atoms were. It's like there is a scale of knowledge from 0 to 1000. The Greeks had a score on that scale of 1, we are at 2, maybe 3. We must keep tearing into this puzzle! Cern (the accelerator project) may soon begin to answer some questions............

Answer 3

No. After the big bang the universe was expanding, but at a reducing rate due to gravitational attraction. Since about 7 billion years ago, the rate of expansion is accelerating. This is due to a repulsive force acting equally and uniformly across the visible cosmos.
Our universe is finite but unbounded.
You need to think your ideas out more clearly, you are mixing gravitational attraction with universal expansion.
Also, don't use 'infinity' too much - infinite is not a number, large or otherwise, it is a methematical concept. Theories that contain infinities are generall wrong.

Answer 4

I'm so totally with you, man. I mean, I'm not a freak who dreams about this every living moment, I just think there could be another universe! How can you say no! I know I know "But how can you say yes?!"

People! You can't base your life on scientific facts! There is not a logical reason for everything!

Black holes!

Other universes!

Bermuda Triangle for crying out loud!

Where's the creativity? Say when the plane crashed in the Bermuda Triangle, it sunk into the deep city of Atlantis! I'm not saying that scientist are wrong. Scientist have been anazing and have made technology that makes the human proud of our priveligies!

Some will say "Oh, this girl is crazy! She just reads too many fantasy books..." Okay when you were a kid did you ever try opening your wardrobe to see if Narnia was on the other side? Because I know I did. And loads of others did. But that's decreased because of people becoming less in tune with their imagination due to science! x-x

Answer 5

And you are going to be a physicist when you 'grow up' aren't you? I think that your question is 'unanswerable' because we can't 'really ever know' the 'true answer' but it's still a 'very good question' and I'm glad you put it on Y!A ... I'm going to ask my husband what he 'thinks' about it ... it's certainly an 'interesting proposition' that there are an infinite number of 'universes' and some can be 'attracting' ... and are some 'repelling' and some 'neutral' and what about the ones that 'are attracted' or 'repelled' ... HMMMM.

Answer 6

Since it appears to be expanding in all direction equally, the 'big bang' (an explosion) still seems to be the best explanation.
And the newest theories point to other universes called membranes, or branes for short, the collision between which create new universes (big bangs).

Answer 7

possibly it's expanding and at the same time accelerating due to a inverse square law that gravity become less of a bonding the further it expands away from other objects, but your question have provoked thoughts on this subject before And not yet answered it, interesting none -the-less, I shall star this question

Answer 8

I think.... each christmas light is a galaxy..... not a universe.

Answer 9

I would say it is possible and we probably will have no way of ever knowing if that is true.
