The edge of a black hole is merely rays of light that are too close to escape but far enough to avoid the gravitational pull of the black hole. But if these light rays were to come in to contact with one another, they would be subject to the power of the black hole, and would therefore be pulled into it. If two black holes were close enough to one another, they will eventually form a single black hole that was either larger or equal to the size of the two original black holes combined. The fact that a black hole can never decrease in size corresponds to its entropy (measures the amount of disorder of a system). The second law of thermodynamics states that the entropy of an isolated system always increases, and that when two systems combine to form one system, the entropy of the new system is is greater than the sum of the entropies of the parent systems. If the universe around a system is losing matter and energy, that the system must be gaining the matter and energy from its surroundings. Based on the second law of thermodynamics, black holes should be gaining energy and matter because its surroundings are losing matter/ energy. Because we cannot study the entropy of a black hole, we can only assume that it would be higher than the entropy of the surroundings. However, the problem with this theory is the fact that black holes should have a temperature. If they contain entropy, like the second law of thermodynamics explains, than they should give off some amount of radiation. But, according to their definition, they cannot emit radiation.
The Origin And Fate Of The Universe
The general theory of relativity, developed by Einstein, implies that the universe was created during the big bang and that the universe would end if and when it collapses again or is pulled into a black hole. But the state of the universe during the early stages of its existence is generally unknown to us, and will most likely stay that way. The idea that the universe's existence was infinite, with no beginning or end did not sit well with many religious leaders. They argued that God created the universe, implying that there was an exact moment of creation. Quantum mechanics may unlock the history of the universe and it may be the key to predicting the fate of the universe. We know that the universe is constantly expanding. We also know that as it expands, the temperature of the matter in the universe decreases. This means that if the universe is expanding infinitely, it will eventually reach a point where particles of matter are moving infinitely slow.
