Is gravity the only force that only attracts?
In short: While gravity is known for its purely attractive nature, theorists suggest that sound waves might actually possess negative gravity, challenging our fundamental understanding of how forces interact in the natural world.
In the natural world, most fundamental forces possess both attractive and repulsive properties. Gravity is a unique exception, as all known mass is positive and therefore attracts other positive masses.
However, theoretical physics explores the possibility of negative gravity. Specifically, some theorists suggest that sound waves may exhibit negative gravity, a concept that would fundamentally alter our perception of physical interactions.
