In the formula,
E = mc^2
c represents the constant value of the speed of light in a vacuum,
exactly 299,792,458 m/s, it does not represent the actualy velocity of a massive object (an object with mass).
The unit for energy (E) is the Joule.
But the Joule can be re-written in terms of the base SI units.
1 Joules = 1 kg (m/s)^2
If you look at the SI base unit for energy, doesnt it look remarkably similar to E = mc^2 ?
On the left, one has units of energy, on the right, units of mass multiplied by a velocity squared.

it's mass times the speed of light squared, and it's easier than writing the equation more "simplified" - note: the universe is expanding at faster than light speed - limitations on SOL are only within the universe

E=Mc^2 is talking about how much energy something is when its mass is converted to Energy. The speed of light is just a constant.

Light propagates in all direction, Therefore it is a square of the distance.
