What exactly would a consumer gravitation camera record, and how would we be viewing it?
Then there is the issue of what you would point it at and the technical problem of how you record it. The effect on gravity that you have is kind of a candle next to the sun compared to the earth in general.
Actually it is kind of too early to tell at this point. Could be no less analog of a process than IR films are. I haven't taken the time to dig into things yet, but as far as I'm aware the method of detecting the waves isn't strictly speaking a digital process.
all my film is gravitationally affected. It falls to the floor if I let go of it. And 4x5 flops around the film holders due to gravity. You just can't get away from gravity. It's serious stuff.
Yeah, I guess because I am a chemist. But, there is an electro magnetic spectrum. There apparently is no gravito magnetic spectrum nor is there a gravito electric spectrum. That is despite what some science fiction authors try to describe. And so I would say that there will be no such device ever invented. But just in case, I won't vote!
today's announcement was a step along the way... but while film is sensitive to individual photons, gravity is wildly different. The analog to a photon ( that carries electromagnetic force ) is, hypothetically, the graviton. According to that article, a perfect detector with the mass of Jupiter, put into close orbit around a neutron star, would be expected to detect one gravton every 10 years due to the low interaction with matter. So if you think your IR film with a deep IR filter is slow, you ain't seen nothing yet. Be prepared to wait billions of years to form your gravity camera picture. Now, a gravity wave camera, well, the beginnings of that are already in progress. Cool video about today's announcement and future plans is here
Dudes, this has been done and it was an early confirmation of Einstein's work. Wait for a total eclipse, take a picture of the region around the sun and you will see gravitational lensing of objects behind the sun. You can wait till later in the year and take a picture when the sun is not in the way and compare the plates.
