Nice topic penroc3
I posted a somewhat tangential thread
on using, let's call it astronomical
phenomenon, as a means of communication, some time ago. I didn't originate the concept/idea, but it was the central plot theme from a book I'd
I think it's an intriguing idea, but I would probably advocate sticking with some form of comms using parts of the EM spectrum or lasers/concentrated
As others already laid out, Einstein's general theory of relativity set forth the speed of light, and this speed is also the upper bounds at which
matter, other than say theorized exotic particles or forces we don't yet understand, can travel through spacetime. So gravwaves don't buy
us anything in terms of the alacrity of information we could send.
Further, gravity is still subject to the inverse square law
, so we are not
gaining any edge in the distance we can send information, vs light/EM radiation.
So if gravwaves don't allow us to send information farther or faster than what we use know for communication, then, what is the payoff for using it?
One idea popping into my mind is that it could be a very clever way to prevent interception of a signal. Anybody can see pulses of light. Probably
anybody with tech newer than circa the early 20th century can detect EM radiation. But gravity...if someone were to figure out how transmit data via
gravwaves, very few people on Earth right now (and perhaps even off Earth!) would have the instrumentation/expertise to detect the gravwaves. Even
with very simple encryption, you might have yourself the perfect transmission medium, at least for some time.
All of this is predicated on our ability to generate gravwaves. Our understanding on how that process works right now is that the intensity of gravity
is proportional to mass in an area of space time. If we somehow figure out how to generate gravwaves, that would imply that we had learned how to
cancel and un-cancel mass (which would form the peaks and troughs I guess of our information wave), and if we knew how to do that....the implications
go far beyond data transmission.
Very neat discussion.
