The findings were reported at this week’s April meeting of the American Physical Society in Tampa, Florida, by Michigan State University’s Gary Westfall. They were also presented at a press conference attended by several scientists from the collider.

Brookhaven physicist Samuel Aronson said that having established the quark-gluon-liquid nature of the earliest universe, the laboratory expected to plumb the liquid’s properties, such as its heat capacity and its reaction to shock waves.

The liquid seems to flow very freely—with almost no viscosity, or syrupiness—despite containing huge amounts of material for such a tiny space, the physicists said. This early universe-juice thus approximates an ideal, or “perfect” fluid, the scientists said.

Although the laboratory had previously announced results reporting a possible recreation of the early universe, the researchers hesitated in the past to be definitive about the claim.
