Physicists Create Mind-Bending ‘Negative Mass Fluid’ That Moves Forward When You Push It Back

Negative Mass That Accelerates Backwards Could Help Examine Blackholes

No one undertakes research in physics with the intention of winning a prize.

It is the joy of discovering something no one knew before.

Stephen Hawking

American researchers have managed to surprise science geeks across the globe, creating a unique fluid with negative mass – but that actually stands for an object moving forward when pushed back. They also claim that it can be used to study some of the more challenging areas or cosmos.

What Is The Negative Mass Like?

The physicists from the Washington State University claim that the negative mass, unlike the regular physical objects that we witness all around, accelerates backwards when pushed. This rarely created phenomena in the laboratory, shows a less institutive side of Newton’s Second Law of Motion, which states that a force is equal to the mass of an object times its acceleration (F=ma). In your daily life, you only see the positive effect of this law, which is, when you push anything it moves away.

Michael Forbes, a WSU assistant professor of physics and astronomy and an affiliate assistant professor at the University of Washington explained that anything with negative mass, when pushed, accelerated backwards. So instead of going away, it will come towards you.

How Was The Negative Mass Created?

The WSU team, in order to create negative mass, made the Bose-Einstein condensate in which particles move very slowly and behave like waves. To do this, they cooled rubidium atoms to just above absolute zero. The Bose-Einstein condensate is a group of atoms that are cooled to such a low temperature that there is hardly any movement left in the group and the atoms start behaving as if it were a single atom. It was first predicted by Satyendra Nath Bose and Albert Einstein, thus, the name.

After reaching this stage, the scientists used lasers to kick atoms back and forth until they started spinning backwards. Apparently when rubidium rushes out fast enough, it behaves as if it had negative mass, and once pushed, it accelerated backwards. The researchers and physicists claimed that what is ground breaking in their research is the fact that they have exquisite control of the negative mass using their technique.

This control gives them a new tool to engineer experiments to study similar behaviours in astrophysics such as neutron stars and cosmological phenomena like black holes. Mr. Forbes explained that it provides another environment to study the peculiar fundamental phenomenon.

What Is A Black Hole?

The black hole is probably one of the most interesting things in cosmology, not only for the researchers but also for the general public. It is apparently that region in space with a gravitational field so intense that even light can not get out, which is one reason why, it can’t be seen because to see anything, light has to reflect from its surface. The researchers detect black holes apparently by the difference in behaviour of nearby stars. The stellar black holes are formed by collapse of the centre of a massive star that also causes a supernova, or an exploding star, blasting part of the star into space.
