I’ve got a secret and it’s “x”squared.

Why do scientists hide their theories under the square root sign ?

Is it because they can’t be bothered revealing precise numbers?  If “x”= 100, the square root of x is 10. If x = c and c = the speed of light at 300,000 kilometers a second, then the square root of c2 is c which is 300,000 kilometers a second.

Why do scientists obscure numbers by squaring them? Is it because they can’t be bothered writing out complete numbers? 10 squared is 100; 100 squared is 10,000. We’ve heard that e=mc2. But can anyone explain the meaning of c2, how it makes sense to exceed the limiting unvarying velocity of light(in vacuo) by multiplying it by itself: 300,000 x 300,000 = 900,000,000,000 nine hundred billion miles per second a number greater than the assumed age of the earth.

And what does “in vacuo” mean? Albert Einstein takes care to specify “in vacuo” whenever he refers to the constancy of light’s velocity implying that when light travels through Aristotle’s space where “Nature” disallows bodiless openings like vacuums that might permit light’s constancy or Galileo’s bodies of various dimensions and mass to fall to the earth at the same rate.
