Gravity Waves have finally been observed, not once, but twice, and the era of Gravity Wave Astronomy is now here. So far our detectors can only pick up really powerful events in the form of black holes multiple times the mass of our sun colliding together, but as the science matures we should be able to detect less energetic events. Why did I say finally been observed? Because they were predicted by Albert Einstein right around 100 years ago as part of his General Relativity Theory, and it took us until last year to begin to detect them.
