RE: Physics Nobel Prize 2017 - A short introduction to Gravitational Waves
Interesting and well-written post, @galotta. I have what might be a silly or ignorant question given my lack of background in physics. You mentioned that gravitational waves travel at the speed of light through the universe. Would it be theoretically possible for us to use something like this for communication in the future over interplanetary distances?
In theory yes, in practice no.
You would need to use ridiculous amounts of energy to produce a tiny signal which you can't even focus properly. The general problem is that gravitation is so much weaker than electromagnetic interaction that you will always want to use light/electromagnetic signals in the first place.
Or you can send hard drives by a reasonably fast ship :D
That makes sense, thanks.
