The research team used “two mirrors” to create negative mass particles. Can be used to build low-power lasers. The concept of negative mass (the mass of an object is negative), which mainly exists in condensed matter physics, is common in the field of astronomy, and is used to understand the creation and evolution of the universe. Recently, researchers at the University of Rochester created particles with negative mass through the interaction of laser pointer optical microcavities with confined light.
· The research team used “two mirrors” to create negative mass particles that can be used to build low-power lasers. On Earth, all objects conform to Newton’s law, that is, if you apply a positive force to an object, the object will move with a positive acceleration. However, the property of a substance with a negative mass is exactly the opposite. When you apply a positive force, it moves in the opposite direction.
In other words, when you try to push it, it moves towards your hand. The research team used “two mirrors” to create negative mass particles that can be used to build low-power laser pointers. It sounds like science fiction, but in physics, it’s real, and the University of Rochester research team created particles with negative mass through specific devices.
