Crazy to think we know of only about 3000 pulsars!

Jesus what a cool fact : "Even light produced in the sun's core takes more than 100,000 years to reach the sun's surface." Because of its density.

Very interesting! I wonder how accurately we are able to detect gravitational waves today, and what kind of precision this would require?

It’s not accuracy, it’s sensitivity and it is something people will be working on for years.

I was a physics grad student in the 1990s and I remember going to a talk about the LIGO project back then, it took until 2015 until they got their first detection.

There is hope that will build much better detectors that don’t just detect gravitational waves from colliding ‘compact objects’ (black holes and neutron stars) and can pick them up from starquakes plus the ‘big bang’ and/or inflation era.
