The concept of acceleration is not tp photons... they only exist
at the speed of c.


Hi Sam

I only say this because I have two daughters (11 & 7), so a bullet from
a gun analogy would be accepted!

I know that you know your stuff and I'm learning from you!

I think the most important point to make to the girls is that
because light particles have no mass, the don't have to be
"accelerated".

Push the button an a laser pointer and the light leaves at c.
One and a half second later, it's all the way to the moon.
Round trip to the moon and reflected back is just under three
seconds. Shorter times for shorter distances.
