"Erik Verlinde, 48, a respected string theorist and
professor of physics at the University of Amsterdam,
whose contention that gravity is indeed an illusion
has caused a continuing ruckus among physicists,
or at least among those who profess to understand it.
Reversing the logic of 300 years of science, he
argued in a recent paper, titled “On the Origin of Gravity
and the Laws of Newton,” that gravity is a consequence
of the venerable laws of thermodynamics, which describe
the behavior of heat and gases."
