    Does the matter of negative mass exist?

    Wondering if mass can be negative? looking for this information online? On this Ask Expert page find responses from experts.

    Matter mass is always positive in nature. Is there any possibility of matter having negative mass? If not, can we create matter of negative mass in reality. According to physics if mass became negative it will get displacement in direction opposite to applied force.

    Negative Mass is an opposite sighn. If negative mass exist then it would voilate the laws of Universe: Energy, momentum and therefore, negative mass cannot exist. The reference content is available in Wikipedia.

    Infact, negative and positive mass produces counterintuitive behaviours. The negative mass cannot exit because it breaks one of the essential assuption behind the brilliant brain Einstien's theory of general relativity in 1914.

    We remember Albert Einstien for more than his disheveled hair, big eyes, and witty charm. He is genius and physicist who changed the way we see the world. His famous formula of E=mc2 revolutionized scientif thought and brought us into the nuclear age through his special theory of Relativity. He reasoned that since everything in the universe in motion. He also believed that the speed of light is the only constant by which we can measure space, time or physical mass.

    If Negative mass exist, it would turn out that for negative mass there would be no event horizon and this will lead to naked singularity because when distance from the singularity is large, Physicists simply ignore it.

    Negative mass appears to voilate the energy.

    Let's put this outside the context of therautical physics. In real physics we know, just like energy, the matter just changes it's forms. Negative matter means absence of matter. You can't have negative matter. However the lack of matter in certain regions of space such as black holes goes to show that the law does not hold. For same reason many such concepts don't hold true in space. And this makes you wonder if it is possible to have negative mass to measure it's existence. I think black holes being interesting phenomenon it makes us question the definition of the time, negative mass, absence of energy etc. I'd say there is no conclusive research on this. Not atleast the most peer reviewed research. That;s one reason I think many of us have disagreement towards concepts of negative mass.

    The concept o negative mass is against the rules of Universe. For any matter to exist it should have mass and this is Universal truth. We humans have hardly explored the Universe, so maybe hypothetically we can assume that there can be the existance of negative mass in the Universe just like the concept of Black holes where we have only made assumptions but have no proof of its behavior. But as per the present known theories of physics we can definately conclude that negative mass cannot exist. Even the basic atomic theories can explain this. Every matter will have atoms and atoms will have electrons, protons, nucleus, etc. An atom cannot exist without a nucleus and as nucleus has mass the atom will have mass. Therefore the concept of negative mass is impossible as per present human knowledge and theories.

    Actually, the idea of negative mass does not exist. It holds only the negative sign and on the basis of the physics theory, it does not possess. Think the mass or positive mass exists because a thing exists in this universe. The negative mass is against the rule of this universe.
