Gravity, as commonly understood, is a fundamental force of nature that attracts objects with mass towards each other. It is responsible for the phenomena such as the attraction between the Earth and objects on its surface, the motion of planets around the Sun, and the formation of galaxies.
Negative gravity, on the other hand, is a concept that does not exist in our current understanding of physics. In traditional physics, gravity is always an attractive force, meaning it pulls objects towards each other. Negative gravity would imply a repulsive force, where objects with mass would push away from each other.
However, negative gravity is not a recognized or observed phenomenon in the scientific community. The concept of negative gravity would contradict our current understanding of gravity and would require a significant revision of the laws of physics. there is no experimental evidence or theoretical framework that supports the existence of negative gravity.
It's worth noting that in some speculative theories or fictional settings, negative gravity may be mentioned, but it should be understood as a concept outside the realm of current scientific knowledge and understanding.
