Do gravitational fields have negative energy?

Answer 1

The negative energy is not yet discovered. We still don't know the presence of negative in the energy in gravitational field.

Gravitational fields do not possess negative energy.

Energy conservation is one of the universe's constants; negative energy does not appear to exist at all.

An object in a gravitational field has exchanged potential energy for kinetic energy when it falls into a gravitational well, which transforms gravitational potential energy into kinetic energy.

It takes energy to return to the potential energy needed to escape a gravitational field, which is sometimes mistaken for the gravity field having negative energy.

It was previously believed that potential energy was stored in the gravitational field itself, but this is not possible. For example, imagine an asteroid that is falling very slowly toward Earth. Where did the asteroid's potential energy come from?

The answer is complex and requires an understanding of General Relativity. An object in a gravity field actually has less mass. Lifting an object against gravity increases its mass. The energy is explained by #E=mc^2#.

Gravity is the result of matter curving space time; it is not a force. Only particles have energy, and negative energy particles have never been observed. Gravity fields have no energy at all.

According to general relativity, gravitational fields are an expression of spacetime's curvature brought about by the presence of mass and energy; they do not contain negative energy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
