1 Black Holes

2 What is a black hole? What is a black hole? A black hole is an infinitely dense object that occupies a single point in space. It is so dense that not even light can escape from them. A black hole is an infinitely dense object that occupies a single point in space. It is so dense that not even light can escape from them. Why is it impossible to escape from a black hole? Why is it impossible to escape from a black hole? It is impossible to escape from a black hole because its immense density warps space, creating a gravitational pull that not even light can ignore. Thus making it a black hole. It is impossible to escape from a black hole because its immense density warps space, creating a gravitational pull that not even light can ignore.

3 If we can not see a black hole how do we know they exist? If we can not see a black hole how do we know they exist? We know they exist because we can see the effects of a black hole. We can see the cosmic jets that they generate as well as the objects they pull in. We know they exist because we can see the effects of a black hole. We can see the cosmic jets that they generate as well as the objects they pull in. What are cosmic jets? What are cosmic jets? A cosmic jet is a release of matter from the are surrounding a black hole. Cosmic jets move at almost the speed of light. However how they move this fast isn’t really understood. It is believed that opposing magnetic fields play a key role A cosmic jet is a release of matter from the are surrounding a black hole. Cosmic jets move at almost the speed of light.

4 How can something like a black hole be created? How can something like a black hole be created? Scientists aren’t entirely sure. Because the changes in the universe happen so slowly, we’re talking in hundred of thousands of years maybe more, the process that forms a black hole has yet to be observed. However it is believed that when a massive enough star explodes it will then implode and due to the unbelievable power of that implodsion the star will collapse into a black hole.

5 Okay why should we study black holes? Okay why should we study black holes? Well aside from curiosity and a pursuit of knowledge, black holes could prove instrumental in improving our understanding of gravity. The conditions that a black hole creates allows scientists a natural laboratory where they can test out their theorems. This is important because well computer models can aid scientists there is still nothing like the real thing. Which is what black holes provide.

6 White Holes, what are they? White Holes, what are they? White holes are the opposite of black holes. Matter is continuously pushed away from a white hole, instead of being pulled in. They have been predicted by as of yet no evidence has been found. White holes are the opposite of black holes. Matter is continuously pushed away from a white hole, instead of being pulled in. They have been predicted by as of yet no evidence has been found. Well if there’s no evidence, why have they been predicted? Well if there’s no evidence, why have they been predicted? Mostly because of the fact that a similar mathematic equation describes electricity, gravity and magnetism. But so far only electricity and magnetism have been proven to be repulsive as well as attractive Mostly because of the fact that a similar mathematic equation describes electricity, gravity and magnetism.

7 How are black holes and white holes related to wormholes? How are black holes and white holes related to wormholes? It is theoretically possible for a black hole and a white hole to ‘connect’ and form a gateway. However both would have to be spinning holes. Which further complicates matters as then both would have to be electromagnetically in sync. Also no white holes have been found as of yet. It is also believed that any gateway would be too small for a human to use. It is theoretically possible for a black hole and a white hole to ‘connect’ and form a gateway.
