No. That is not something telling us about earth nature long ago. Keep trying.
A gravitational wave is the result of 2 massive bodies (like black holes) colliding. This triggers an immense burst of energy so huge that space itself ripples from it. These ripples are gravitational waves that travel at the speed of light through space.
LIGO is a facility designed specifically to detect such waves.
LIGO detected the collision of 2 blackholes within 60 minutes after turning it on.
For us to be able to detect such wave, it needs to reach us first.
The source of it would have to be VERY far away, for obvious reasons. It's quite a burst of energy....
So the wave needs to reach us from VERY far away. Like billions of lightyears.
If the physics of the past were different, these waves should NOT exist.
But they do.
EDIT: typo, added the "not" in the second to last sentence
