Newton's second law of motion says that when an object's mass is accelerated via a net force, it is directed in the same way of the force applied to it. A new research has come up with a fluid claimed to possess negative mass, which denies this law of motion.
According to United Press International, the fluid is made out of negative mass, that is when it is pushed it accelerates backward. This is a very new kind of experience for the scientists, who are quite amazed by this unnatural quality of the derived matter.
Reportedly, the liquid consists of rubidium atoms, which are cooled to a temperature that is almost equal to absolute zero. The cooled atoms go into a phase known as the "Bose-Einstein" condensate, where the atoms start behaving like waves. The negative mass matter is termed by the scientists to behave like a "superfluid", which indicates to the movement of its particles in synchronization without wasting any energy.
According to Mail Online, the researchers use lasers in order to slow down the moving particles of the negative mass, causing them to cool. This leads to the removal of high energy particles with steam, which cools the particles down again by a few notches. The lasers then keep hold of these atoms in a way that they are being kept in a bowl and breaking it will lead to the rubidium to escape.
Next up, the researchers apply a second set of lasers to spin the atoms back and forth. This changes their movements and as a result, rubidium that rushes out will behave in a way which indicates as if it has negative mass. The researchers say that it seems like the rubidium has hit an invisible wall, and once pushed, it starts moving backward.
Scientists suggest that the results of this research on negative mass Researchercan be used in studying analogous physics. They also say that this will lead to better understanding of processes that are not viable to experiment, such as black holes, neutron stars and dark energy,
