Hypothetically, let`s say that one day our Sun is suddenly removed from the galaxy. For us, on earth, would take up to 8.3 minutes to notice that the sun was removed, since the distance from the earth and the sun is approximately 8.3 light-minutes.
However, what about gravity? Would we feel immediately here on earth? Could we say then that, if gravitons really exist, they travel faster than the photons?
