This newcomer is making LIGO feel old.
Here’s my ‘Gravity Wave Detector’:
Launch a satellite about about a million miles like the Webb Space Telescope.
Make this satellite capable of measuring the Red/Blue Shift of distant stars, 24/7/365, the farther the stars the better.
Have the satellite point it’s 3 cameras/detectors at three separate stars, X-Y-Z Axis, about 90°, or greater, apart.
A Gravity Wave that passes between the stars being observed and the satellite will show a definite change in the Red/Blue Shift of the stars. The magnitude of the change in shift will tell you the size of the wave, the differences in the three axes times and magnitude with give you direction.
