Opinions Sought on Hawking Radiation and High Energy Collisions

In summary, this website argues that Hawking radiation isn't proven and that high energy collisions in the upper atmosphere travel at a fast speed. There is also a report available that clears up some of the confusion.

Can someone give some opinions on the following?

The 2 main arguments from this site i can tell are: that hawking radiation isn't proven. And that high energy collisions in the upper atmosphere travel at a fast speed & the small black holes can escape from Earth unlike in the lhc.

I watched a video & it said it can take a few years before the small black hole would be noticed. Just wanted some insight thanks.

Yes, Hawking evaporation has not been observed. But mini black-hole creation has not been observed either. The creation of mini black holes in LHC requires the same theory as the one from which black hole evaporation is derived, modified in such a way that Hawking evaporation occurs even faster than what would be required for LHC to be safe. It does not make any sense to use a speculative extension of a theory to claim that LHC will produce black hole and then deny the well established part of the theory which says black hole evaporate.

LHC collisions do not occur at zero total momentum, because they do not occur on the whole of the nuclei. The collisions occur on nuclei constituent and the total momentum is not fully balanced. It is very basic relativity to calculate the velocities involved, and compare them to the escape velocity of Earth. Even if you have your mini black hole sitting at the center of the Earth, they would still not cause any damage over the lifetime of the Earth.

Everything has been repeated over and over again. There is a very good detailed report available.

thanks for clearing that up. :smile:
 

1. What is Hawking Radiation and how does it relate to high energy collisions?

Hawking Radiation is a theoretical phenomenon predicted by physicist Stephen Hawking in which black holes emit radiation due to quantum effects near the event horizon. This radiation is thought to be a result of the creation of particle-antiparticle pairs, with one particle escaping the black hole and the other falling into it. High energy collisions, such as those that occur in particle accelerators, can also create these particle-antiparticle pairs, providing a potential way to study and observe Hawking Radiation.

2. Why is there debate surrounding the existence of Hawking Radiation?

While Hawking Radiation is widely accepted in the scientific community, there is still some debate surrounding its existence. This is because it has yet to be directly observed or measured. Some scientists also question the theoretical basis for Hawking Radiation, as it relies on the combination of quantum mechanics and general relativity, two theories that have yet to be fully reconciled.

3. What are some potential implications of confirming Hawking Radiation?

If Hawking Radiation is confirmed, it would provide further evidence for the existence of black holes and contribute to our understanding of their behavior. It could also have implications for our understanding of the early universe and the effects of gravity on a quantum level. Additionally, if we are able to observe Hawking Radiation in high energy collisions, it could open up new avenues for studying and testing theories in particle physics.

4. How are scientists attempting to study and observe Hawking Radiation?

There are several ways in which scientists are trying to study and observe Hawking Radiation. Some are using mathematical models and simulations to better understand its properties and behavior. Others are using advanced technology, such as particle accelerators, to create conditions similar to those near a black hole's event horizon. There are also ongoing efforts to detect and measure Hawking Radiation directly through experiments and observations.

5. What are the potential implications of Hawking Radiation for our understanding of the universe?

The confirmation of Hawking Radiation could have wide-reaching implications for our understanding of the universe. It could help us better understand the behavior of black holes and the effects of gravity on a quantum level. It could also provide new insights into the origin and evolution of the universe. Additionally, if Hawking Radiation is proven to exist in high energy collisions, it could have implications for the development of new technologies and advancements in particle physics.
