Black Holes: Comparing Hawking & Kaku Theories

In summary, Prof. Steven Hawking's revised Theory of Black Holes does not necessarily rule out the existence of parallel universes, but it does remove the need for a specific type of parallel universe related to the stuff falling into a black hole. Other theories, such as the Many Worlds interpretation of quantum mechanics, may still involve parallel universes. The Two Big Bang Theory proposed by Dr. Raj Baldev also has implications for M Theory. However, it is ultimately only one man's opinion that has changed.

Steven Hawking's / MKaku. Who's right about Black Holes?

Does Prof. Steven Hawking's revised Theory of Black Holes rule out the existence of parallel universes? What about the Two Big Bang Theory by Dr. Raj Baldev, what implications does this theory have for M Theory.

Does Prof. Steven Hawking's revised Theory of Black Holes rule out the existence of parallel universes?
No. It removes the need for a particular type of parallel universe - one where the stuff falling into a BH ends up. But many other theories also invoke parallel universes. His concession means nothing for the Many Worlds interpretation of quantum mechanics, for example.

Science fiction writers need not panic, yet. And in the end, it is after all only the opinion of one man which has changed...
 

What is a black hole?

A black hole is a region in space where the gravitational pull is so strong that even light cannot escape from it. This phenomenon occurs when a massive star collapses in on itself, or when two or more black holes merge together.

What is the difference between Hawking and Kaku's theories on black holes?

Stephen Hawking proposed that black holes emit radiation (now known as Hawking radiation) and eventually evaporate over time. On the other hand, Michio Kaku believes that black holes do not actually completely evaporate, but rather form a "remnant" that retains all the information that falls into it.

How can we observe black holes?

Black holes cannot be directly observed since they do not emit any light. However, scientists can observe their effects on surrounding matter and stars, and can also detect gravitational waves emitted by black hole mergers.

Do black holes have a surface?

According to current theories, black holes do not have a physical surface. Instead, they have an "event horizon" which is the point of no return for anything that crosses it. Inside the event horizon, the gravitational pull is so strong that even light cannot escape.

What are some potential applications of understanding black holes?

Studying black holes can help us better understand the laws of physics and the behavior of matter in extreme conditions. It can also provide insights into the nature of space and time, and potentially lead to advancements in technologies such as space travel and energy production.
