Gravity is the force that holds our Solar System together. It allows planets and moons to keep their elliptical orbits around the Sun. Even though humans have explored only a small portion of space, we know that our Solar System orbits the center of the much larger Milky Way galaxy. Without gravity, our Solar System would not be able to maintain this orbit.
Gravity and friction
Gravity Electro-magnetic force Direct impact or contact
This is due to Newtons first law. Because their is no gravity the object will move in a straight line unless a outside force is applied to it. Such as the gravity of a near by planet/object.
Any and all matter.
They work at both the places depending on their needs.
There certainly is gravity outside the atmosphere. For example, it is gravity that keeps the Moon in orbit around the Earth, and the Earth in orbit around the Sun.
of course no
Based on purely statistical arguments, many scientists hold the opinionthat there is a high probability of life outside of earth.But no evidence of it has been observed yet.
If you were observing the ball from the outside (of the ball) the center of gravity is in the middle of the basketball.
They are gas planets
If there is indeed anything "outside of the Universe", science has no knowledge about it.
Scientists try to find out more about the natural world. They regard questions about the existence or otherwise of souls as outside their field. Others may interpret scientific knowledge as helping to define whether souls exists, but that is not the intention. Individual scientists may hold personal beliefs about whether souls exist, but these beliefs are private and not based on scientific evidence.
There is a large debate about whether or not there are microorganisms outside of the Earth. Many scientists believe that there are.
As of Dec 2010 - we have no evidence that anything lives anywhere outside of Earth. We hope this may change, but until evidence is detected, the answer is the same - nothing.
Acceleration is caused by gravity or an outside force on the object.
Mars
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.
