I do not want to upset any one here, but I would like an answer to two more questions.

The questions are about Einstein’s formula.

First question is: Is the following calculation correct?

I know that the more accurate calculation of the light speed is: 299.792,458 meters per second; but to keep the calculation simple I’m using the approximation of 300,000 km/s.

E= m * c^2

Mass = 2kg

If c^2= 300,000 km/s * 300,000 km/s = 9*10^10 km/s

9*10^10 km/s * 2 = 180,000,000,000 km/s ?? Speed of light?

What does the number 180,000,000,000 km/s represents, or where and how did it change into energy?

        Wouldn't polar coordinates be more appropriate? - RL - 12/21/2021 4:44:23 AM
