Using lasers, scientist measures the viscosity(stickiness) of a gas(sixth state of matter)

Scientist have found out a new way to measure the viscosity i.e., stickiness in general term with the help of ultra-cold Fermi gas of lithium-6 atoms in this case, embedded to laser light.

This experiment can be considered as a big breakthrough in science because, the measurements verify that it can be used as scale model of exotic matter like super-high temperature superconductors, the nuclear matter of neutron stars, and even the state of matter created microseconds after the Big Bang.

All thanks to Quantum Mechanics for this breakthrough.
