If gravity dominates the expansion of the universe what would happen to the universe?

It would begin to collapse inwards towards its most massive points until finally it all met at one point, according to some theories.

What is the oscillating model of the formation of the universe?
The Oscillating Universe Theory is a cosmological model that combines both the Big Bang and the Big Crunch as part of a cyclical event. That is, if this theory holds true, then the Universe in which we live in exists between a Big Bang and a Big Crunch. In other words, our universe can be the first of a possible series of universes or it can be the nth universe in the series.

What would happen to the moon if there was not any gravity What about the planets?
Without gravity, there would be no largescale structure to the universe. If it simply stopped existing, the moon would fly off from earth orbit; the earth and planets would fly away from the sun into deep space, and not only would the solar system dismantle itself but so would the galaxy. Also, the atmosphere would drift off into space, as would (the shortly thereafter dead) human race, and everything else not fixed to the surface of the planet. However, gravity is very much built into the universe - the structure of the universe is based on it being there (and having the relationship with other fundamental forces that it does). It's a very hypothetical question - the thought that you could "lose" gravity but keep everything else in the universe somehow well-behaved.
Why do nebulas happen?
The same reason why most things happen; gravity. Every speck of matter in the universe attracts every OTHER speck of the universe with gravity. So a a large thin cloud of gas in space will, over time, become a smaller thicker cloud of gas. Given enough gas and enough time, the cloud will collapse under its own gravity to form a star, or a planetary system. But if all the gas is attracted in all directions, why would it all fall together HERE, rather than OVER THERE - and since the gas is all over, why would it collapse at all? We think that the shock of a somewhat-distant supernova explosion begins the collapse process by pushing enough gas together for gravity to finally do its thing.
What would happen if only gravity were on the earth?
we would be heavy
What actually is the big rip theory?
The Big Rip is one of the hypotheses for the end of the Universe. It has been observed that the expansion of the Universe is actually accelerating rather than slowing down. Based on this some scientists think the Universe will expand so fast that the fundamental forces, including gravity, will be overwhelmed and everything in the Universe will be "ripped apart". In other words, matter will disintegrate, and even spacetime may be destroyed, causing the Universe to cease to exist altogether. The Big Rip would not happen in an instant. Rather as the Universe expands it will go through a process of disintegration in which every stucture, from the largest galaxies to the smallest subatomic particles, will break down. The fate of the Universe depends on whether gravity or dark energy will win the "war". In the Big Rip hypothesis, dark energy accelerates the expansion of the Universe and overcomes gravity. If gravity "won" the opposite of the Big Rip would occur: the Big Crunch.
Does gravity happen in other parts of space?
Yes; wherever in the universe there is mass like planets, stars of even meteors, there is gravity.
Is the big crunch definitely going to happen?
It seems it won't happen. The expansion of the Universe is accelerating - instead of slowing down, it expands faster and faster.
Will the big bang ever happen again?
Scientists have largely dismissed the notion of a cyclical universe. So the short answer is: no, this universe will probably not undergo collapse and re-expansion.
What would happen in the universe in the future according to bigbang theory?
According to it the universe will contract and all particles come closer look like a ball and burst again. But it happens with gravity but gravity not as strong as at time of bigbang. This is now the question.
What is oscilating universe theory?
This refers to the idea that after a period of expansion, the Universe will eventually contract again (due to attractive gravitational forces), return to a tiny point, and explode again in another Big Bang. This no longer seems likely to happen, since it has been found that the expansion of the Universe is actuall accelerating, not slowing down.
Is the universe is expanding because of gravity?
In a closed universe, the expansion will eventually halt and contraction due to the pull of gravity. Check out the 'Electric Universe Model'. It should provide more detailed explanations. Beware! It's a deep subject and one can get lost/confused. Take it slow to groc in fullness. (BTW The Closed Universe Model mostly proven false or highly unlikely.) It is understandable that you are having trouble understanding the closed universe theory since as has already been previously mentioned it is most likely not true. What I think most people struggle to grasp is why the universe can at present be expanding but then this sudden change occur where this expansion is not only halted but reversed. This kind of question rivals questions like why did the Big Bang happen. The truth is we don't really know why this might happen, but it was established as a possible answer since if it were true, we could then explain the Big Bang. It was a solution designed to dodge a question. See link for further information
In space what will happen in the future?
the universe is expanding. so in the future all the planets will loose gravity leaving their orbits everything will become a chaos
When the universe retracts and finishes back at the point of the 'big bang'and disappears up its own BS where will that be?
Theorising that that will indeed happen, it will happen everywhere. The expansion and contraction of the universe is not about objects moving relative to each other through space, it's about space itself getting bigger and smaller. From the data we have at the moment, we expect the universe to expand forever.
After universe ends what will happen?
First, we have no information on whether the universe will end, or if it will continue in perpetuity. It's either one or the other - and yet either answer would be astonishing. Second, we have no idea how the end of the universe might come about, or what the conditions at the end time would be, or if the concept of "after the end of the universe" has any meaning at all. One interesting concept is that of an oscillating universe; a Big Bang of expansion, with gravity overcoming everything in the end and pulling every shred of matter back to itself in a "Big Crunch". This could be the prelude to another "big bang". Each universe would be completely new and unaffected by the last.
Is it possible that the universe keeps dying and being reborn and we're just experiencing one universe in a much longer possibly eternal string of universes?
That possibility has been considered before. The basic idea is that the Universe collapses due to gravity, and then expands again in the next Big Bang. However, there are several problems with that. For one, the Second Law of Thermodynamics would still apply. In other words, the next universe would be different from the current one, and the cycle could not continue forever. (Note: If you want to understand astronomy, a basic understanding of the Second Law is a must.) Also, this is not supported by observational evidence. For this to happen, the expansion of the Universe would have to slow down over time. The opposite is actually happening: the expansion of the Universe is accelerating.
What would happen if gravity stops for 2 seconds?
The World Would Be Destroyed.Gravity is the Expansion Acceleration of all Mass in the universe.Gravity is the "root" of every form of Energy we know.If Gravity ever ended, the world would be destroyed immediately.EinsteinGravitydotcom
