Final answer:
According to Einstein's theory of relativity, if all the mass in your body were suddenly converted into energy, there would be a significant decrease in mass.
Step-by-step explanation:
According to Einstein's theory of relativity, if all the mass in your body were suddenly converted into energy, there would be a significant decrease in mass. This is due to the mass-energy equivalence, which states that energy is related to the mass of an object at rest. When mass is converted into energy, the rest mass of the object decreases.
