299792458 m/s * 299792458 m/s = 89875517873681764 m/s

lets see

number * number = number

m = the unit that only describes what the number represents

s = the 1 second

10 mph * 10 mph = 100 mph

not

100 m^2 / h^2

that would be ridiculous





3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
