﻿ E = mc²

E = mc²

##### Firstly:

E = energy

m = mass

c = the speed of light (186,000mps or 300,000km/s)

What this formula states is:

Energy = Mass ∗ The speed of light ∗ The speed of light.

Or E = m (186,000 mps²)

Or E = m (34596000000)

Or E = m (3.4596 * 1010)

Simple logic will tell you that E = mc² is the same as:  A = bc²

∴  If C = 3 (c²=3², or C = 9).

Then A = B (9) According to the theory of relativity, mass and energy as commonly understood are two names for the same thing (one is not changed to the other).  If Energy & Mass are correlated then they are also co-dependant.  Whatever change happens to one also happens co-‘relative’ to the other.

Thus to say Energy = Mass is correct.

If Energy = Mass, then the more energy something has the more mass it has, and indubitably the more mass something has the more energy it has.

 C (The speed of light) is a constant, so the other numbers will change only variably with each other, while C has no changing effect on their value.

 It is now understood that although this formula is correct, it is also misleading in the subject of massless objects, where momentum becomes important as in the formula E=pc (p=momentum).   This being true does not take away any validity of the truth that E=mc² (or that E&M are co-relative).
