The speed of light is still c in infinitsimal stretches of space (or due to quantum bubbles, approximately c).

The reason it takes years for sunlight to reach the surface is due to constant reabsorption of photons in the plasma environment inside the sun. That's a whole different thing from the fundamental constant c differing in other parts of the universe.

Look up nonstandard analysis.

Hey /sci/, I'm settling a bet with my math teacher. I know that x/0 is TECHNICALLY undefined, so anytime I write 0 or infinity, replace it with "approaches 0" or "approaches infinity." Because 0/x is 0, than x/0 is the reciprocal of 0, which approaches infinity. Now, here is where we disagree. She says that they can't be reciprocals because anything multiplied by an unlimited quantity (infinity) is infinity, and anything multiplied by 0 equals 0. But I say that these two non-values cancel out, resulting in a net answer of 1. Who is correct in this situation?
