gravity is a force that pulls us on to the ground and earth makes the gravity.In space there is no gravity (scientist call this zero gravity) so gravity isn't pulling the universe back because there is no gravity outside planets.

What is a universe that expands and comes back together repeatedly?
a closed universe.
How fast will a spacecraft have to go to create artificial gravity?
Speed doesn't create artificial gravity. Acceleration does. That means change of speed.That's why you feel heavier when the elevator starts up, and lighter when it starts down.And it's why you feel a force (like gravity) pushing you back into the seat when the car starts forward,and a force (like gravity) pulling you forward out of your seat when the car slows down.As long as the spacecraft (or car) is speeding up, there will be a force (like gravity) pulling backwards.As long as the spacecraft (or car) is slowing down, there will be a force (like gravity) pulling forward.If the spacecraft (or car) goes 32.2 feet per second faster after every second, then the forcewill have the same strength as earth's gravity.
Is gravity the same everywere in the universe?
The laws of gravity seems to be the same everywhere in the Universe. There have been experiments using distant objects in the Universe to try and measure if it might be different far away (or back in time!), but no effect has been found to date. In fact, the question seems to tie in with the question whether the laws of physics are the same everywhere in the Universe. This is because one can derive the equations of general relativity assuming the laws are the same everywhere for everyone. This is a bit technical, but basically if you want the laws of physics to be the same for everyone you MUST have gravity in the form Einstein proposed, there is no other way. Of course other deviations from our laws of physics have been looked for, but again none have been found.
What force acts to pull natural and artificial satellites to earth?
Gravity. A natural satellite aka asteroid, then meteor, then meteorite all get pulled to Earth through gravity. With artificial sattelites it's tge same thing, gravity. The difference is we launch our satellites to the perfect zone around the planet where they become trapped in orbit around us. Sometimes things occur that bump these satellites out of their orbit and gravity takes over, pulling the satellite back to the surface.
What are the three possible fates of the universe?
1. The universe will keep expanding forever 2. The expansion of the universe will gradually slow down, and the universe will approach a limit in size. 3. The universe will stop expanding and start to fall back in on itself.
What is the ultimate fate of the universe according to the classical Big Bang advocates?
To go back together because of the force of gravity pulling everything into a pinpoint center, causing a singularity, and then probably causing another big bang.
Why is the universe expanding and what force is it expanding into is it anti gravity?
The initial expansion of the universe was caused by the Big Bang's explosion of matter. Just as explosions here on earth cause expansion, so it was then. The math today, however, shows that the universe should be compressing again, as the energy lost over time would then be overridden by gravitational forces pulling everything back together. I'm sorry to say there's no such thing in our universe as anti-gravity, though. The universe's fate is generally accepted to be expansion forever at an ever slowing rate. To answer as to why this occurs, dark energy and dark matter are the forces at work - not anti-gravity.
What causes the back end of car to feel like its pulling to one side?
amount of force or gravity pulling on it
When you jump why does gravity pull you back down?
gravity is a constant force pulling down on you. jumping doesnt escape that fact.
What is a universe that expands and comes back together repeatedly?
a closed universe.
A universe that expands and comes back together repeatedly?
a closed universe.
This matter spread out around the universe with no structure But each little bit of matter exerted the force of on each other little bit?
Gravity is why it keeps coming back together.
What is pulling back on what if People pulling on dragon?
So its a bit like tug of war if people are pulling a dragon, then its going to be pushing the other way. Its a force and gravity pushing together at the same time, but it is quite a hard question so i dont blame you. Sorry if this doesnt help but im only in year 4
If gravity is pulling you what is pushing you back?
Nothing. Actually gravity is pushing you down but there is enough air resistance on the earth to stop us feeling heavy and crushed
Why is there increased risk of damaging your back when the load you are lifting is away from your centre of gravity?
This is because you are poorly balanced when the load is away from your center of gravity. The poor balance leads to you pulling muscles and damaging your back.
How does gravity control the size and shape of the universe?
big bang explosion forced everything out from small place , at some point gravity will pull it back in
