Gravity waves are the most powerful force in the universe but until now we didn't have any evidence they existed, until yesterday when we discovered a large black hole expelled from a galaxy at a million miles an hour.
And the only force strong enough to expel a large black hole from a galaxy are gravity waves.
When two galaxies collide, the two central black holes circle one another creating gravity waves strong enough to sling shot one of the large black holes out of the galaxy.
Who knows what we will do with gravity waves one day. They may replace all our energy sources. And we may be even able to focus gravity waves to enable us to surf through the galaxy.
But remember, you heard it here first.
