Using gravitational waves to hunt for dark matter

Using computer simulations, an international team of cosmologists have discovered that observations of gravitational waves from merging black holes may unveil the true nature of dark matter. Their finding will be presented today at the 2023 National Astronomy Meeting by co-author Dr. Alex Jenkins of University College London.

It gets better every day but have we got long enough to get there?

That is a worry, wipe ourselves and the planet out before we fulfill our potential.

We are down to cigarette paper thickness.

Excuse the cynicism, but you can’t tell the difference between a black hole made of dark matter and a black hole made of baryonic matter. It’s the “black hole has no hair” theorem.

So black hole merging, and the gravitational waves from them, ought to be completely independent of the existence of dark matter.

I’d rather talk to you about turtles.
