So, you do you want to hear two black holes colliding? Take a listen (audio from the New York Times):

Imagine coming up with a theory that upends 200 year-old accepted laws of physics because something about it just doesn’t make sense to you. Imagine not having any kind of instrumentation to even experiment the equations that you come up with and in fact, would take a hundred years for you to be proven right. Imagine coming up with an equation so elegant as this:

E = mc²

That was Einstein. But imagine also, the minds that came up with LIGO (Laser Interferometer Gravitational-Wave Observatory) and the willpower of some who pushed for building it amidst all the budgetary constraints and the skepticism? Yesterday’s announcement of the first direct detection of gravitational waves is not just about proving Einstein’s prediction on the existence of ripples in space-time set off by violent and cataclysmic events in the universe. More than anything, I find it very human in the beauty and perseverance of the people who made this happen. So, yesterday should not be rejoiced by the scientific community alone but by all of us because, see what we can be capable of? By the way, nice Googly, insider scientific joke there:

If you need a refresher on Einstein’s theory of general relativity, there’s a great infographic here. Or if you’re like me, I get a refresher during an afternoon car ride with my husband, which is pretty cool too.
