Possible methods to convert gravitational waves into storable energy?
This is a good question, and a difficult task.
Part of the problem is that most objects in the universe are effectively transparent to gravitational waves - they don't really absorb or scatter them, s …

Would it be possible to ride a gravitational wave?
No can do.
I was able to find the answer here, written by LIGO scientist Dr. Amber Stuver:
How valid is the wave-like-in-water analogy? Can we “surf” these waves? Are there gravity “peaks” like there …

What would the gravitational wave signature of an Alcubierre drive look like?
Alcubierre's solution to the Einstein field equations (Alcubierre 1994) gives us a metric - an expression describing how spacetime curves - of the form
$$ds^2=-dt^2+(dx - v_s(t)f(r_s)dt)^2+dy^2+dz^2$$ …

Seeing Using Gravitational Waves
The strain, $h$, of a gravitational wave is
$$h\sim\frac{1}{R}\frac{GM}{c^2}\left(\frac{v}{c}\right)^2$$
to a relatively decent degree of accuracy. Here, $R$ is the distance to the source, $M$ is the …

Would the gravitational waves from a binary black hole system make a feasible weapon?
No, this would not be a feasible weapon.
Although I originally posted an answer to this question five years ago, I've since deleted it and am starting anew. One reason I deleted it is that the answer …
