Lets see now; if I give that “nothing” a name, call it ‘space’ or ‘heaven’ then give the “something” a name such as ‘mass’ or ‘earth’ then give a ‘constant’ motion to that ‘something’ then the totality could be called the ‘universe’.
That is not very scientific because it does not involve mathematics so let me try it again.

How about if I indicate the “mass/earth” as a letter k. And “space/heaven” as a letter u. Then call the motion by the name ‘energy’ and use the “constant” as a reference point.
Since my idol Mr. Einstein used the speed or acceleration of light as the numeric quantity for the ‘constant’ I should do the same.
From this information then I can write a mathematical formula. For instance if I wanted to know how much ‘motion’ or ‘energy’ there is in any quantity of mass, all I need to do is put appropriate figures in the following formula.
e=(u/k)c
Since these days there is no “nothing” in this universe (there is ‘something’ everywhere) the ‘u’ must be calculated by using the formula ‘u=ck squared’. Naturally you must use the same ‘k’ quantity for both the ‘u’ and the ‘e’ calculation in order to get the right answer.
Since Einstein did not take into consideration the ‘u’ factor he had to square the ‘c’ but the ‘e’ calculation still comes out the same.

What seems REALLY strange is that this information has been in front of millions of people for thousands of years and no one understands it.
