The equation E=mc^2, which is derived from Einstein’s theory of relativity, shows the equivalence between energy (E) and mass (m) and demonstrates that mass can be converted into energy and vice versa. When mass is converted into energy, such as in nuclear reactions, the total energy of the system is conserved.

However, it’s important to note that the gravitational effects of mass are not directly related to its energy content. Gravity is a fundamental force that arises due to the presence of mass or energy, as described by Einstein’s theory of general relativity.

When mass is converted into energy, the total mass-energy of the system is conserved, and the gravitational effects remain. The energy released from mass conversion would still contribute to the overall gravitational field in the vicinity. This means that even though the form of energy may change, the gravitational effects associated with the original mass would persist.

In other words, the gravity associated with a mass is not lost or “go” anywhere when mass is converted to energy. The gravitational field remains, although its magnitude and distribution may change due to alterations in the mass-energy distribution.

It’s worth mentioning that in extreme cases, such as when energy is radiated away from a system, the system’s mass may decrease, leading to a small change in the gravitational effects. However, this effect is typically negligible for most everyday energy conversions.
