Stephen Hawking Says No Black Holes Exist

By Brent Matsalla

     Stephen Hawking is the most famous living scientist in the world and he gained much of his notoriety from the bizarre space objects known as “black holes.” Now Hawking is saying that no black holes exist in our universe.

A black hole is a theory from physicists that regions of space and time in our universe can become so dense that nothing can escape their grasp including light. The density increases until the huge gravity of a black hole eventually generates what is known as an “event horizon.” Stephen Hawking then took those theories and applied quantum mechanics to black holes back in 1974. Hawking’s point of view sparked much controversy in the scientific community and that controversy still continues today.

Generally, quantum mechanics does not play well with any other grand theories of general relativity or physics. It is even more complicated when combined in situations where both of the grand theories are relevant. When the quantum mechanics was applied to the theory of black holes, Hawking was able to determine that black holes are not actually black. However, what Hawking did find is that the phenomena will emit radiation in small quantities that would cause them to eventually shrink and evaporate.

The black hole radiation theory also made suggestions that when a black hole finally dies, it will take everything inside of it. However, this theory is disproved by quantum mechanics. According to physics information matter is never destroyed even if it is devoured by a black hole. Some other theories are that the black hole releases this information when it dries up and evaporates. Hawking disagreed with the theorists originally, but has now changed his mind by explaining how it just might be possible. It has taken him 30 years, but Hawking has now had to concede to a wager made seven years ago with another physicist. . . .
