Lightspeed is identical for all inertial frames of reference.
**** off cretin!
Got any performed experiments that show lightspeed is other
than c in vacuo?
The only ones I'm aware of measure lightspeed at c plus or minus
about a few parts per billion -- in fact, that's why in 1983
the standards bodies decided to throw in the towel and *define*
the meter in terms of the length of the second, and lightspeed;
the old Kr-86 definition just wasn't accurate enough, apparently.
Of course, you can claim that all of the scientists on that body
were deluded, if you like.
BTW: 1 part per billion would be about 38.5 cm, relative to the Moon's
distance of 3.85 * 10^8 m.
