Is science too much about assumptions?

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

No. Photons never move slower than c, 300,000,000m/s

I can bet you a Steam game over this if you want.
