Black Holes and G-Waves

Packed up for a day trip and took the family out to Livingston Louisiana for Science Saturday at the LIGO Gravitational Wave Observatory. I have to admit, my family is a bunch of Astro-nerds who don’t mind sitting in a science lecture, so this was pretty much up our alley.

We hadn’t been here in a while but wanted to see what was happening with the recent wave discovery they had. For those of you who really aren’t into science or hadn’t paid attention, the science world was rocked with the detection of gravitational waves caused by the collision of 2 black holes in a distant galaxy over a billion years ago. One of them was 36 times as massive as the sun, the other 29 times. As they approached the end, at half the speed of light, they were circling each other 250 times a second. The two holes coalesced into a single black hole with the equivalent mass of 62 suns. All in a fifth of a second, Earth time. That event rippled through space time and was detected at LIGO.

Freakin Awesome! I guess Einstein was right. 

This was a great time for kids and adults. The exhibit hall was very nice with lots of demos and the staff was very friendly and knowledgable. The lectures were very informative covering the history of LIGO and the discovery of the black hole wave. It was nice to see the large crowd and the interest in the facility.
