In summary, Hawking's new paper argues that black holes do not have an event horizon, challenging our current understanding of these objects. He provides theoretical calculations and simulations as evidence and suggests that the event horizon only exists in classical physics. This also challenges our understanding of the singularity at the center of a black hole, as the event horizon was thought to be its defining feature. This discovery could have significant implications for future black hole research and may even challenge other established theories.

2013 AUG Paper - Hawking

"...gravitational collapse produces apparent horizons but no event horizons behind which information is lost."

"The absence of event horizons mean that there are no black holes - in the sense of regimes
from which light can't escape to ininity."

Its not a good idea to pay attention to only two sentences of a paper!
It should be figured out that why Hawking wrote those sentences.

It would also help if you provided a link to the paper so that we could read it as well.

This is a fascinating new development in the study of black holes and the nature of gravity. Hawking's paper challenges the long-held belief that black holes have event horizons, which are points of no return for matter and information. This has significant implications for our understanding of the behavior of matter and energy in the extreme conditions of a black hole.

The concept of event horizons has been fundamental in our understanding of black holes and their role in the universe. However, Hawking's new paper suggests that this may not be the case and that there could be a different mechanism at play.

This is an exciting development because it opens up new possibilities for our understanding of the physics of black holes. It also raises important questions about the nature of gravity and how it operates in these extreme environments.

Further research and experimentation will be needed to fully understand the implications of Hawking's findings. But this new perspective on black holes has the potential to greatly advance our understanding of the universe and its fundamental laws.
 

1. What is the main argument of Hawking's new paper?

The main argument of Hawking's new paper is that black holes do not possess an event horizon, meaning that they do not have a point of no return for objects and information.

2. How does this challenge our current understanding of black holes?

This challenges our current understanding of black holes because the event horizon has been a fundamental concept in the study of black holes for decades. It is believed that nothing, not even light, can escape from within the event horizon.

3. What evidence does Hawking provide to support his claim?

Hawking provides theoretical calculations and simulations to support his claim. He argues that the event horizon only exists in classical physics, but in the quantum realm, it can be avoided due to the phenomenon of Hawking radiation.

4. How does this affect our understanding of the singularity at the center of a black hole?

This challenges our understanding of the singularity at the center of a black hole because the event horizon was thought to be the defining feature of a black hole. Without it, the singularity may not exist in the way we currently understand it.

5. What implications does this have for the future of black hole research?

This discovery could open up new avenues for black hole research and potentially lead to a better understanding of the nature of these mysterious objects. It could also challenge other theories, such as the no-hair theorem, which states that black holes are characterized by only three properties: mass, charge, and angular momentum.
