Just to keep PWM happy:
“In theory, it is possible to detect gravity waves coming from the future as gravity is believed to be able to travel through time.”
Is it true that gravity is believed to be able to travel through time?
What does that even mean?
Roughbarked says, even if it is believed, it ain’t necessarily so, which I believe.

Bing says:
Gravity does not travel in time. However, gravity can affect time. According to Einstein’s theory of general relativity, where gravity is stronger, time passes more slowly. This effect is called Gravitational Time Dilation1. In other words, time runs slower wherever gravity is strongest because gravity curves space-time1. I hope this helps!

Nothing to do with gravity but,
I’ve often wondered why the god-fearing Merkins are so happy to accept the words of the song “It Ain’t Necessarily So”, so I did a quick Binge and found:
It Ain’t Necessarily So — the Gershwins at the top of their game
which really doesn’t answer the question, bus does have a lot of interesting background info.

According to general relativity, gravity travels at the speed of light, so does not travel in time.
As a check on that, gravity waves confirm it.
However, if you want to discard general relativity, then all bets are off.

GR = gravity travels at light speed is what I thought.
Was just wondering if there was any theoretical basis for speed of gravity > c.

Well it must inside an event horizon otherwise light would escape a black hole
