Black Hole Presentation
Transcript of Black Hole Presentation
G Yes, this does apply to black holes. There is no difference between the gravitational field of a black hole and any other spherical object of the same mass. People say that a black hole "sucks in everything" in its surroundings but this is only true within a short distance of a black hole.In general, the closer you are to an object that has a gravitational field, there is more gravity exerted on you.

Drawing isotopes has nothing to do with black holes because a black hole is not made up of any element, it is just empty space. Describing how a radioactive isotope differs from a stable isotope does not relate to black holes because a black hole does not have isotopes. The difference between a chemical and nuclear reaction is that a nuclear reaction takes place in the nucleus while a chemical reaction takes place in electrons. This is not related to black holes because they are not made up of atoms. Fusion does remotely relate to black holes. Black holes are created by an exploding star which rips a hole in space creating a black hole. The star is "powered" by hydrogen. When it runs out of hydrogen, fusion takes place turning hydrogen waste into helium and so on. When a star runs out of its fuel, hydrogen, fusion takes place turning hydrogen waste into helium and from helium to lithium and so on. Fission is not related to black holes. Fission is the process in which the nucleus of an atom is split by a shot neutron, creating energy. The relationship of mass and weight sort of relates to black holes. Mass always stays the same but weight changes depending on gravity. If an object is on the horizon of a black hole the gravity will increase.
