Gravitational Waves Discovered!

DNews breaks down one of the latest and biggest discoveries in physics. Seriously though, this is amazing. The folks running the LIGO (Laser Interferometer Gravitational-Wave Observatory) have pulled off something that Einstein could only predict in his lifetime. Now that gravitational waves have been proven to exist, we’re one more important piece closer to solving – or at least comprehending – the vast puzzle that is the universe.
