"Could both gravity and the Big Bang be an illusion? In January 2010, Erik Verlinde, professor ofTheoretical Physics and world-renowned string theorist, caused a worldwide stir with the publication of On the Origin of Gravity and the Laws of Newton, in which he challenged commonly held perceptions on gravity, going so far as to state ‘for me gravity doesn’t exist’. If he is proved correct, the consequences for our understanding of the universe and its origins in a Big Bang will be far-reaching." - Mark H from Bookmarklet
""We have other phenomena in Physics like this," Verlinde continued. "Take a concept like ‘temperature’, for instance. We experience it every day. We can feel temperature. But, if you really think about the microscopic molecules, there’s no notion of temperature there. It’s something that has to do with the property of all molecules together; it’s like the average energy per molecule." To Verlinde, gravity is similar. It’s something that only appears when you put many things together at a microscopic scale and then you suddenly see that certain equations arise." - Mark H
Seems like something Slippy would appreciate. - Mark H
In that seeming, you are entirely correct. Yet more food for thought with little chance of discussion :-) - Slippy: Formless from Android
Though imma try anyway: Both are illusory. Gravity is an effect. The big bang theory is an extrapolation.:-D - Slippy: Formless from Android
Difficult to discuss this when it's way outside my knowledge of physics. And when it starts veering into metaphysics then I tend to switch off anyway. I find philosophy entertaining but ultimately pointless and try to avoid it when I can. - Mark H
He's not talking about an illusion in the sense that gravity has real effects in the real world. Illusions are in the mind. And in science I thought everything was BEHAVES AS and DESCRIBED AS rather than IS A. Newton and Einstein described how the world behaves, not how it is, so there's plenty of room for gravity being emergent. - Todd Hoff
I confess, I haven't actually clicked the link to see the meat of his reasoning. 2.5" screen, slow connection. Though I found the title and topic interesting enough :-) - Slippy: Formless from Android
Gravity works because we believe it does, then? Because reality agrees that it should? - MoTO: Tufted Coqeutte
Wow. Now I'm GLAD I didn't click thru. Also: BAZZA! - Slippy: Formless from Android
Just my conjecture. And: SLIPPEH! Edit: Come to think of it, I think Warren Ellis may have put it in an issue of "Planetary". "Gravity works because we believe it does..." or some such. - MoTO: Tufted Coqeutte
To paraphrase Pratchett: Without belief, the sun won't rise. Instead, a mere ball of flaming hydrogen will be seen in the sky. - Slippy: Formless from Android
