NASA astronomer Michelle Thaller talks about a heavy subject matter: neutron stars. These dead stars are so dense that just one teaspoonful of neutron star matter would equal the mass of Mount Everest.
Two neutron stars in orbit around each other will eventually collide, and when they do, they create ripples in the fabric of spacetime. Thanks to LIGO, the Laser Interferometer Gravitational-Wave Observatory, scientists can detect these gravitational ripples by detecting disturbances in laser light.
Albert Einstein correctly predicted the existence of gravitational waves in his theory of general relativity, 100 years before astrophysicists first detected them.

So what do they think?
How is the power of science advancing understanding? How are philosophers and theologians tackling these fascinating questions?
Let’s dive into The Well.
