a photon at rest, how droll.
Cecil, this sounds like a regular poster David.Perhaps he is pulling
your leg with his nonsence


We know that we can accelerate an electron to 90% of the speed of

Ah, yes!

No Newtonians in this crowd. *Perhaps it was the relativistic term
"speed of light" that confused this group so much. *Let's restate it
in units that Newton could have appreciated.

We know that we can accelerate an electron to *167,770 miles/s - it
