Re: Question regarding relativity.

From the point of view of a photon, there is no time.  No space either.
The universe is a point.

From our point of view, of course, things seem different, but we can
agree with a photonoid that the interval between any and all events
along the photon's world line is always exactly 0, where interval
is defined as ds^2 = dx^2 + dy^2 + dz^2 - c^2 dt^2

Just remember: relativity is seriously twisted.

Max thrust of the Space Shuttle Main Engines is a bit over 390,000 lbs.
NASA doesn't know about Newtons, but I'll leave that  as an excercise
for the reader (hint, g = 10 m/s/s).  Proton booster is probably more
more powerful yet I'd guess.  Ask over at sci.space.tech: Henry will
know.
