Forget about the speed of those mystery photons, and just focus upon detecting whatever's coming towards us at -c. (just like our universe is supposedly expanding at c) ~ BG

Your collective > knowledge of physics is quite diminutive. So what makes a photon go? While you're at it, tell us how fast is gravity and what makes it go? ~ BG
From: Peter Webb on 22 Apr 2010 01:58 Some parts of the Universe are moving towards us at speed c. Some of the light from other galaxies, for example. We can know nothing about this light until it actually reaches us. No information (eg that light was emitted by a distant galaxy) can travel faster than c.

What makes gravity go? How fast is gravity? Tell us why a quantified finite supply of photons go in only one direction, whereas immortal gravity seems to continuously go in all directions at the same time. Once more: Should any parts or items of whatevers in our universe be collapsing towards us at c, could we detect it? Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG / Guth Usenet

Perhaps as far as we know, yet gravity and the information it represents seems to be worth at least 2c. ~ BG |
