      There is actually gravity in space – that is why planets orbit the sun, and keeps the sun in place in the Milky Way galaxy. The reason you experience “zero-gravity” in space is because it is very weak – it’s called “microgravity”. Black holes are really cool, aren’t they!? Black holes are formed when a star “dies” in a supernova, a massive explosion of energy and matter, that leaves behind an incredibly dense “neutron star”. If there is enough matter left behind, it can contract under its own gravity and become a black hole, which has such a strong gravitational field that not even light can escape :O crazy huh?
