Not only do you get heavier, but your length also decreases. Does this mean that faster walkers are denser than slower walkers? PS how did you get the formula to appear? I can’t get the equivalent for length to show.

We know a poem about that don't we boys and girls?
There was a young man called Fisk
Whose fencing was exceedingly brisk
So fast was his action
The Lorentz contraction
Reduced his rapier to a disk
(With apologies to Fitzgerald)
P.S. You can work wonders moving equations around if you copy them as images Mike
