So why does gravity pull you down and not push you away? Imagine someone went under the trampoline and pushed up. The ball would roll away! This would be a gravity hill, not a gravity well. As far as scientists know, matter — or stuff — always makes gravity wells and not gravity ...
2 Why does gravity only pull?doi:10.1016/S0262-4079(09)61588-8WrightCharlotteELSEVIERNew Scientist

Why does a tossed javelin draw a sumptuous arc before it stings the ground? Regardless of the nature of the projectile, the arc one draws through the air is precisely a parabola. The reason is, of course, gravity, the only force that affects its motion (neglecting air resistance) after it...

But once an object gets big enough, the force of its gravity pulls down any parts that stick out too far, creating a round shape. Pluto is big enough to be round. The real challenge to the ex-planet was the third test, which gets to the heart of what many astronomers think of when...
A good example of this is the filmGravity(which is amazing, if you haven't seen it). Sandra Bullock's character's problem is that everything is trying to kill her. The progressive complications get worse and worse until *spoiler alert* everyone is dead except for her. ...
Otherwise gravity will pull you back down to the Earth... MALE PROFESSOR: Actually, that's a common misconception. Escape velocity is simply the speed of an object that's, uh, let's say, shot out of a cannon, the minimum initial speed so that the object could later escape Earth's gr...
