Hi Double-A True his ruler,and clock stays relative in size,but one
effect that is proven by our great accelerators(not around in
Einstien's
time) inertia goes up,and that means even though his scale still can
read he weighs 180 lb going at 99.999999999 of 'c' he now weighs
70,0000 times his rest mass. He died when his space ship past the
speed
of 73% of 'c' 73% of 'c' is my personal figure The
figure of 70,000 times heavier came from the Cern lab. Bert

No, his weight or mass really haven't increased. That's why scientists
have moved away from the term "relativistic mass". Only his momentum
has increased. Since there is the speed limit at c, velocity can no
longer increase linearly as you keep adding momentum, but the added
momentum is there.

The additional momentum will in no way affect him while in flight.
Only if he should slam into a stationary brick wall will he do an
amount of damage to it as though he weighed 70,000 x more than his
normal weight (mass).
