## Gravity: an emergent property of spacetime

Study matter and its motion through spacetime...

### Gravity: an emergent property of spacetime

Verlinde was awarded the prestigious Spinoza Prize with Є2.5 millions so he can spend his time researching his pet theory -- that gravity is not a fundamental force, but one that arises as an emergent force, like pressure or friction. Take that, String theorists.

### Re: Gravity: an emergent property of spacetime

Correct me if I'm incorrect but I thought this is how general relativity worked anyway?
Matter tells spacetime how to bend, spacetime tells matter how to move. What we feel as the force of gravity is just an emergent property from bodies moving in a straight line through curved spacetime.

Hmm, I believe Verlinde has a different idea about it. He believes that you just need energy, entropy, temperature, and oh yes, information, and out of that, you get gravity.

See his monumental paper: http://arxiv.org/abs/1001.0785

That looks pretty cool and I'll add that a free version of the article can be found by querying "On the Origin of Gravity and the Laws of Newton" in Google Scholar. Thanks for the pointer ! I'll read it and try to post again if I manage to understand anything to it.

Some interesting discussion of the original paper here and here.

In fact we even had some discussions here on ratskep a while ago:

Lol, looks like my memory for such things doesn't span over a whole year ! Let's give it a second read and see whether I am now a bit more familiar with theoretical physics.

And in the bluuuuuuuue corner, arguing that gravity is not emergent:

Ahhh, bask in the glory of the scientific method and watch the competing viewpoints duke it out.
