I had an argument with some friends awhile back that there is very little that we could find we are wrong about that would surprise me. I think I argued that if we found out cells didn't work the way we thought they did, I wouldn't be shocked. Everyone else seemed to agree that perhaps my cells weren't working properly.
But I stand by my assertion, and the New York Times today has an article that bolsters my convictions.
It’s hard to imagine a more fundamental and ubiquitous aspect of life on the Earth than gravity, from the moment you first took a step and fell on your diapered bottom to the slow terminal sagging of flesh and dreams.If gravity might not exist, what isn't possible?
But what if it’s all an illusion, a sort of cosmic frill, or a side effect of something else going on at deeper levels of reality?
So says 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.
