The premise behind a gravitational sensor is to detect changes to a local space time, in space.

Would it be sorta like how we use sensitive machines to detect vibrations from earthquakes?

Or would it not be possible because the sensor itself would interfere with the readings?

I’d do it the same way as the GRACE satellites do, though maybe there is a better way. https://en.m.wikipedia.org/wiki/GRACE_and_GRACE-FO

LIGO… in space?

Like LIGO but with endpoints at the earth, moon, some Lagrange points maybe

Why have them on there, hidden depending on where you look from or even behind an atmosphere, instead of out in space with zero vibrations?

You're right, that's much smarter
