Scientists from Switzerland created World's Smallest Droplets

May 19, 2013 17:15 IST

Scientists from Switzerland created the smallest drops of liquid ever made in the lab. Scientists carried out a series of experiments at the Large Hadron Collider, the world's largest and most powerful particle collider located at the European Laboratory for Nuclear and Particle Physics (CERN) in Switzerland.

Evidence of the tiny droplets was obtained following the collision of protons with lead ions at velocities approaching the speed of light. These short-lived droplets are the size of three to five protons-that is about one-100000th the size of a hydrogen atom or one-100000000th the size of a virus according to scientific calculation. These small droplets flow in a same manner as quark-gluon plasma does.   It can be defined as a state of matter that is a mixture of the sub-atomic particles that constitutes protons and neutrons and only found at extreme temperatures and densities.

Scientists proposed that the whole universe once consisted of this strongly interacting elixir for fractions of a second after the Big Bang when conditions were dramatically hotter and denser than today’s conditions. Since then the universe has spent billions of years expanding and cooling, the only way scientists can reproduce this primeval plasma is to bang atomic nuclei together with a very large amount of energy.
