Negative mass refers to a hypothetical concept in physics where mass is assigned a negative value. In standard physics, mass is always considered positive, representing the property of matter that gives it inertia and is subject to the force of gravity.
Negative mass has been explored in theoretical discussions and mathematical models to understand its potential consequences and implications. However, it is important to note that there is currently no experimental evidence or observation supporting the existence of negative mass in the physical world.
In hypothetical scenarios where negative mass is considered, it is often associated with peculiar properties. For instance, objects with negative mass would exhibit some counterintuitive behaviors, such as accelerating in the opposite direction of a force applied to them. This is due to the reversal of the gravitational interaction with positive mass objects.
It is worth emphasizing that while negative mass is an interesting concept to explore mathematically and in thought experiments, its existence in the physical universe is highly speculative and not supported by empirical evidence. At present, no known objects or particles have been observed or identified to possess negative mass.
