The point of science is to learn. Maybe there's nothing practical to LIGO, maybe in 200 years we have artificial gravity. There's no way to know.

- hereme888 3y agoThanks. It just seems so far out to me that I have a hard time envisioning why spend time and energy in this.
- eigenket 3y agoA reasonable mental model is to view LIGO as a (weird) telescope. Most telescopes work by detecting some form of electromagnetic waves while LIGO works by detecting gravitational waves, but its purpose is pretty much the same as any telescope. To tell us stuff about what is happening out in the universe.
