… a little bit, it always has been and probably always will be. But it’s part of the process. Continue reading All physics is wrong!
We’re proving Einstein right all the time. With our phones. Continue reading The relativity experiment you hold every day
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
