A radical new timeline of the life of the universe (credit: Jeremy Teaford, Vanderbilt University)
Vanderbilt University mathematicians have come up with a new theory of “cosmological viscosity” (how sticky the universe is) that challenges current theories.
For decades, cosmologists have had trouble reconciling the classic notion of viscosity based on the laws of thermodynamics with Einstein’s general theory of relativity, according the the team, which has now come up with a fundamentally new mathematical formulation of the problem that appears to bridge this long-standing gap.
