👉 The term "antiproton" refers to a hypothetical particle that, when found in nature, would not be able to interact with matter or have any effect on it. It is often used as a concept in theoretical physics and chemistry to represent particles that are neutral and do not possess an electric charge. In terms of physical reality, antiprotons are hypothetical particles that could exist in the universe but cannot be observed directly due to their extremely low mass compared to other known particles like electrons or neutrons
