Are There Alternative Theories of Gravity Beyond Newton and Einstein?

[Atran]

Hi,

All the time I find Newton's and Einstein's theories of gravity. Is there any other competitive one? Any which is competing with GR?

Thanks...

Not really. There are other theories that agree with experiment, but they all have "tuneable" parameters so they are not really competitive with GR.

Not sure what it means, but here is what I found:

What about Verlinde's? Does it qualify as a theory of gravity?
