What kind of crazy physics made primordial black holes? What does that have to do with the LIGO observations of merging black holes? How can we possibly detect them? I discuss these questions and more in today’s Ask a Spaceman!

0:00.0 | In 2015, LIGO, the laser inner promenor, let me see if I get this right, gravitational wave observatory. |
0:16.7 | I guess the W is silent. |
0:19.3 | Otherwise, it be LIGO, and anyway, that's a different episode. |
0:22.9 | LIGO detected its very first gravitational wave. |
0:26.0 | And it was the merger of two black holes. |
0:29.1 | And this detection was a huge milestone in physics. |
0:33.6 | I've talked about gravitational waves before, but I really will dedicate it whole episode |
0:38.3 | someday to gravitational wave detection and LIGO and all this. |
0:42.1 | The short version is that it took 25 years of development to get LIGO to actually see something. |
0:50.6 | I mean, this signal, gravitational wave signal is super tiny. |
0:55.9 | Even Einstein didn't think it ever be technically feasible to see this. It was a big deal, which is kind of why they want |
1:01.8 | to know about prize. And amongst all the hoopla of that first detection, which was a lot of well-deserved |
1:09.8 | hoopla for sure, but tucked in there was a very |
1:12.5 | strange surprise. |
1:14.1 | And it was almost lost in that noise and hoopla. |
1:17.7 | The surprise was the masses of the black holes involved in the merger event. |
1:24.2 | The masses were weird. |
1:26.0 | And you know me and weird things in the universe. |
1:29.0 | To me, weird means interesting. |
1:32.4 | The two black holes that collided to generate this gravitational wave signature that |
1:38.0 | LIGO detected had a mass, one of them had a mass of 30 solar masses. |
1:43.7 | Solar mass means, in case you've never |
