Physicists recreated the birth of the universe and found a thick cosmic soup
Scientists at the Relativistic Heavy Ion Collider successfully recreated the conditions of the early universe, revealing that the infant cosmos was a friction-free liquid rather than the expected gas.
Physicists smashed gold ions together at nearly the speed of light to mimic the heat of the Big Bang. This process generated a quark-gluon plasma reaching temperatures of four trillion degrees Celsius. Surprisingly, this primordial matter behaved like a near-perfect liquid with almost zero friction.
