If you’re not terrified by neutron stars
, you should be. When my kids were little, they were never afraid of monsters under the bed or lurking in the closet, they were scared of a basketball-sized neutron star wiping out our entire solar system. True story.
So when I read that astronomers actually observed two neutron stars colliding, I got that tingling feeling down my spine. That they detected gravitational waves from the collision isn’t the least bit surprising because the average gravity of a neutron star is two billion times that of Earth’s gravity, despite only being 12 miles wide from end to end.
