Physics, Astronomy & Cosmology / Did Einstein define gravity such that gravity equals spacetime curvature?
« on: 19/04/2016 05:38:54 »
For close to two decades now I've been working to educate physicists who work in relativity and relativity enthusiasts about how Einstein really interpreted the presence of a gravitational field. Almost everyone who understands General Relativity (GR) believes that gravity is a curvature in spacetime. Whether this is right or wrong depends on how to interpret the existence of a gravitational field. There are two ways which are commonly discussed in GR;
1) There is a gravitational field present if the
Tonight I was sorting out my filing cabinet and came across this article which I stumbled across while surfing the internet a very long time ago, printed it out and put it away, forgetting to read it. The name of the article is A Negation of Einstein's General Theory of Relativity and Return to Newtonian Gravitation. The paper is online at:

All the GRists who think that GR is wrong base their argument on the equivalence principle being wrong. All these people think that Einstein said the following:
The reason I held on to it is because the premise of the article, i.e. the theory is wrong, is wrong itself.
What I'd like to know is how many of you actually believe that Einstein said that gravity is a curvature in spacetime? I've brought this subject up and the article many many times in this forum. However there are a lot of newcomers here who might find this interesting. Thank you all for your participation.

In an arbitrary gravitational field no local experiment can distinguish a freely falling non-rotating system (local inertial system) from a uniformly moving system in the absence of a gravitational field.The problem here is that Einstein never said that! What Einstein did say is the following.

A uniform gravitational field is equivalent to a uniform gravitational field.As most of you already know I've carefully documented all of this in a paper I wrote which is online. The article is entitled Einstein's gravitational field. You can find it at:http://arxiv.org/abs/physics/0204044
