Re: What Gravitational Waves Can Say About Dark Matter
#2Perhaps tangential, but is there a frequency of a gravity wave high enough to "cusp" due to one of the quantization limits?

#4They say, in a whisper, "Don't get a degree in particle physics! It's oversaturated, and the field can't even justify building another particle accelerator because it doesn't know what to look for!"

#5TFA doesn't mention recent evidence that primordial black holes are rare. It also doesn't address issues around condensation of dark matter. That is, two dark-matter objects can't collide, because they'll just pass through each other.

If you did a PhD (Emphasis on PhD because an undergraduate degree isn't close to enough) on particle physics solely with career prospects in mind then you probably have bigger issues

They can still get rid of momentum in N-body interactions via gravitational waves (N>=2) or by transferring to it to another body (N>2). The question is whether those mechanisms are significant enough to lead to compact bodies.

In even the classic theory, when the Swartzchild radius of the gravitational wavelet exceeds its width, wouldn’t it naturally form a black hole and end up a cusp?
Like a gravity Kugelblitz.

Thanks.
Is it generally accepted that the large-scale structure of the universe (presumably including dark matter) reflects quantum-scale structure before inflation?

Exactly what I was getting at!
