I’m still fascinated by the discovery of gravitational waves and the implications on our views of reality.
There’s never been anything like LIGO’s direct detection of strong-field gravity, which comes with a statistical significance of 5.1 sigma, meaning there’s only a one in 6 million chance that the finding is an error.It’s proof.
It’s proof that gravitational waves exist, that black holes exist, and that two of the fat monsters—at 29 and 36 times the mass of our sun—smashed into each other 1.3 billion years ago in a collision so violently it sent out ripples across the universe like a brick thrown into a pool. Most importantly, it’s proof that Einstein’s most radical prediction, which mathematically allows for time travel, was correct in a remarkably precise way.
