Why the space didn't have gravity?

You can also think on slightly different lines. Think of the universe or the space that you are talking about to be infinite on every side of a point, the mass distribution in the space under such conditions can also be considered to be homogeneous, think of a point being acted upon by many equal and apposite Iines of force due to gravity in the space. These forces mutually cancel each other. read less

I bet you know the newtons law. Gravity is simply an force of attraction (like the magnets north pole and south pole) between two objects. Gravity exists even between a guy,bus or any material standing near to you. But unfortunately that force is very too weak to be felt. And gravity force depends on the mass of the two objects and also the distance between them. Greater the mass more the gravity, but as the distance between them increase, the gravity will weaken. So you cannot say gravity does not exist in space. We are also an object that on a bigger object (Earth) in space. So if you fly and settle in an asteroid, I you will experience the gravitational pull (but will be weak due to the size of the asteroid). But when you float in the deep space, there is no object near to you, for you to experience the force. read less

There is gravity in space. Gravity is everywhere. It is true that as you get farther from the earth, its gravitational pull weakens. But it dies off quite slowly (compared to nuclear forces). And gravity never goes completely away. When you get very close to some other large body; the moon, Mars, or the sun; its gravity dominates over that of the earth. Only then can you neglect earth's gravity. Because gravity is everywhere in space, objects in space are always falling: towards the earth, towards the sun, and towards the galactic center. There are two reasons that objects seem to be floating without gravity in space when they are really falling. First, space is very large and relatively empty by earth standards. When you jump off a bridge, you know you are falling because you feel the air whooshing up, see the mountains shooting up, see the water fast approaching, and then feel yourself hit the water. Because space is relatively empty, there is little air to feel whooshing past you as you fall and there are no landmarks to indicate you are moving. Because space is so large, it takes you from hours to years of falling through space until you actually hit the surface of a planet (assuming you have aimed properly so that you actually do hit), instead of the seconds it takes jumping off a bridge. The second reason that gravity is not so obvious in space is because objects tend to orbit planets instead of hitting them. Orbiting just means that an object falls towards a planet due to gravity and continually misses it. Because space is so large and planets are so small by comparison, it's actually very hard to hit planets. Space objects typically slingshot in hyperbolic paths around planets, or slip into orbits around them. It takes a team of scientists doing very accurate calculations to make sure a space probe destined for the surface of Mars doesn't miss it. Falling in circles around a planet instead of smashing into it doesn't seem like the gravity we're used to on earth, but it's the exact same kind of falling. Astronauts in orbit around the earth are not experiencing "no gravity". They are experiencing almost all of earth's gravity, but with nothing to stop them. This is known as "free fall". Free fall looks like floating to a person in the falling frame of reference. Confusingly, scientists refer to an orbiting environment as "micro gravity". What they really mean is "micro acceleration", which is another term for free fall. This unfortunate naming convention arises from the fact the word "gravity" is used historically to mean any acceleration, and not just gravity. For example, when an accelerating drag racer experiences four g's, the acceleration is due to the spinning tires and has nothing to do with gravity. read less

According to Newton's law of gravity, F=mg. The earth attracts all bodies towards it. But acceleration due to gravity have a region. That means it attracts within a certain distance.The value of g=9.8m/s2 on earth. All bodies in space have their own gravitational force(G). g=GM/R2 where g=gravitational force,M= mass of earth, R= radius of earth and G= gravitational force. read less

Gravitation is a property of mass; greater the mass, greater the gravitational pull. Space does NOT have any matter that is close enough to exert any pull on a body. Remember: Gravitational force between two bodies is inversely proportional to the square of the distance between the two. Since there are no BIG bodies close by, there is no gravitational force. read less
