Final answer:
The famous equation that can be used to calculate the total amount of energy and matter ever made in the universe is E=mc².
Step-by-step explanation:
The famous equation that can be used to calculate the total amount of energy and matter ever made in the universe is E=mc².
This equation comes from Albert Einstein's theory of relativity and it relates energy (E) to mass (m) through the equation E=mc², where c is the speed of light in a vacuum. It shows that matter can be converted into energy and vice versa.
For example, if you have a certain amount of mass and you want to find the corresponding energy, you can multiply the mass by the square of the speed of light (c²) to get the energy.
