Since the first time gravitational waves were detected, people compared them to “hearing” the universe. Indeed, it’s a completely new way of observing the universe, one that does not need light. But it sure is an odd sort of “sound”.

Awarding the Nobel prize for physics to something related to gravitational waves was a matter of when—not if. Still, one could have argued it was too early: gravitational waves were not a surprise discovery.
Gravitational waves were the first big story on this blog. I like gravitational waves. So when when something about it makes appears on my radar, I listen.
Even if it means it could all be wrong.
Almost exactly a year ago, LIGO announced the detection of gravitational waves. Let’s celebrate answering two deep questions about them. They are hard, but puppies will keep our spirits up! Continue reading 2 deep questions on gravitational waves (with puppies!)
We’re proving Einstein right all the time. With our phones. Continue reading The relativity experiment you hold every day
Most predictions for the winners of this years Nobel prize for physics point to the biggest piece of science news we’ve had: gravitational waves. I’ll go out on a limb and say that I’m not convinced they will. Don’t get me wrong: I’m a great fan of team LIGO’s work, too. The discovery of gravitational waves was incredible, but so was the Higgs boson. LIGO … Continue reading What if gravitational waves don’t win the Nobel prize?
The team at LIGO (the Laser Interferometry Gravitational-wave Observatory) annouced they directly measured the gravitational waves emitted by two black holes merging into one. What are they talking about? Here’s the answer to 4 of the most common questions (plus 2 extra-credit, if you feel up to it). What are gravitational waves? Gravitational waves are ripples in space-time predicted by Einstein’s General Relativity theory. If … Continue reading Four fundamental things about gravitational waves
