Beyond the Standard Model Explanations of GW190521

In summary, the LIGO/Virgo collaboration has detected a heavy binary black hole merger with component masses that cannot be explained by standard stellar structure theory. This has led to the proposal of several explanations based on new physics, including new light particle losses, modified gravity, large extra dimensions, and a small magnetic moment of the neutrino. These models affect the physics of pair-instability differently, resulting in novel mechanisms for forming black holes within the black hole mass gap. However, despite the excitement surrounding these potential new discoveries, it has not received much attention from the media or the scientific community. This could be due to ill-informed bloggers or over-hyping by university press departments. Regardless, the search for new physics, especially at the

For our readers' convenience:
The LIGO/Virgo collaboration has recently announced the detection of a heavy binary black hole merger, with component masses that cannot be explained by standard stellar structure theory. In this letter we propose several explanations based on models of new physics, including new light particle losses, modified gravity, large extra dimensions, and a small magnetic moment of the neutrino. Each of these affect the physics of the pair-instability differently, leading to novel mechanisms for forming black holes inside the black hole mass gap.

If this is for real I'm surprised it's gotten so little attention..?

By whom? Ill-informed bloggers? Over-hyping university press departments?

The whole shebang really. After all, everyone sems to be hungry for any thing that hints at new physics of any kind.

But if you tell my it's basically bunk I'm inclined to take your word for it, though I'd appreciate pointer to flaw in the paper of course. Especially flaws I would have a chance to understand. :)

What is the Standard Model and why is it important in understanding GW190521?

The Standard Model is a theory in particle physics that explains the fundamental forces and particles in the universe. It is important in understanding GW190521 because it provides a framework for understanding the interactions between particles and the forces that govern them.

What is GW190521 and why is it significant?

GW190521 is the name given to a gravitational wave signal detected by the LIGO and Virgo detectors in 2019. It is significant because it is the first ever detection of a black hole merger with unequal masses, providing new insights into the behavior of gravity and the formation of black holes.

How does the Standard Model fall short in explaining GW190521?

The Standard Model does not include a theory of gravity, and therefore cannot fully explain the behavior of gravitational waves. It also does not account for the existence of dark matter, which is believed to make up a large portion of the universe and may play a role in the formation of black holes.

What are some proposed "beyond the Standard Model" explanations for GW190521?

Some proposed explanations include theories that extend the Standard Model to include gravity, such as string theory and loop quantum gravity. Other theories suggest modifications to the laws of gravity or the existence of new particles that could explain the observed gravitational wave signal.

What are the implications of finding a new explanation for GW190521?

If a new explanation for GW190521 is found, it could lead to a better understanding of fundamental physics and the behavior of gravity. It could also open up new avenues for research and potentially lead to new technologies or applications in the future.
