Individual photons don't travel at less than the-speed-of-light. It's constant everywhere. Fact. But considering the whole material, light waves and the information they carry appear to travel at the slower speed in water etc. The mathematics is extremely well backed up. This is one of science's strongest facts you're attacking. |
This gets a little semantical here. Light can't go "less than the speed of light" because it, itself, is light. A light photon can't move slower than itself. However, light can move slower than c, the speed of light in a vacuum, if you change the medium that light is going through. Gelatin, for example
