Images of gluon plasma drops in three geometric shapes: circles, ellipses and triangles. Ed. Javier Orjuela Koop

A group of researchers has created droplets of the first ultraviolet matter created immediately after the Big Bang. In fact, they have achieved a liquid situation similar to that of the quark-gluon plasma, which supposedly filled the universe in the first microseconds after the Big Bang, when the particles were still too hot to form atoms.

They conducted the experiment on the New York accelerator Relativistic Heavy Ion Collider. The packets of protons and neutrons have collided with larger atomic nuclei and have seen that, under certain conditions, quark-gluon plasma drops are formed that expand into geometric shapes such as circles, ellipses and triangles.

With the PHENIX experiment, researchers seek to unravel what is the smallest matter in the early universe that can exist. To begin with, this work has helped to understand how the first ultrabera matter cooled to form the first atoms. The study was published in the journal Nature Physics.

Can anybody find for me cracked XEvil program??? It's best captchas solver, including Google ReCaptcha. Im so need it for my online shop! Already found key for XEvil: 3O1AllSstu5ZyPriRw_piode But dont know, how to use it. Thank for everybody, and sorry for my english! PM me if you know anything, I can pay.
