Following a link from another thread I found:

http://www.askamathematician.com/2011/07/q-does-light-experience-time/comment-page-1/#comment-304613

In answer to the question: "Does light experience time?" the physicist's answer was "Nope!". He/she went on to say:

"There are some things that behave differently when investigated from an “approaching light speed” way of thinking and the “being at light speed” way of thinking. In this case there’s no difference. When something travels at the speed of light it really doesn’t experience any time.

On the flip side of that coin, it also doesn’t experience any distance. The time and location of its emission and the time and location of its absorption are the same from a photon’s perspective."

Nowhere in the rest of the answer, nor in some 30+ comments does anyone mention that this is not universally accepted. No one, that is, until some Bill S. character tentatively chucked a spanner in the works.

I'll not reproduce any more here, but would appreciate comments.

There never was nothing.
