People rarely think in these terms. The idea of negative mass is difficult to comprehend. But the Physicists have created it.
At Washington State University, a bizarre fluid is created which defies Isaac Newton's Second Law of Motion
Condition for negative mass:
A condition is created for negative mass by cooling rubidium atoms to just a hair above absolute zero, creating what is known as Bose-Einstein condensate. In this state particles move extremely slowly, and following the principles of quantum mechanics, behaves like waves. They also synchronize and move in unison as what is known as super fluid, which flows without losing energy.
Researchers have created these conditions by using lasers to slow the particles, making them colder and allowing hot, high energy particles to escape like steam, cooling the matter further. The lasers trapped the atoms as if they were in a bowl measuring less than a hundred microns across. At this point, the rubidium superfluid has regular mass.Breaking the bowl will allow the rubidium to rush out, expanding as the rubidium in the center pushes outward.
To create negative mass, the researchers applied a second set of lasers that kicked the atoms back and forth and changed the way they spin. Now when the rubidium rushes out fast enough, it behaves as if it has negative mass.Once you push, it accelerates backwards.
These peculiar conditions provide another environment to study a fundamental phenomenon.
These negative mass conditions are using to explore complicated concepts of cosmos.
