A new law of physics.

If you reverse everything within a system then relativity everything stays exactly the same unless it's viewed from an external frame of reference.

The curved space-time caused by gravity in the general theory of relativity also applies to ordinary acceleration. There is absolutely no difference between an object following a straight line in curved space-time and an object following a curved path in flat space-time.

Gravity creates inwards curvature which pulls all masses towards each other, rather than conventional acceleration caused by outwards curvature. Gravity is a force of mass rather than energy which is why it's so much weaker than electro-magnetism.

Closing Statement from A wal

I came up with this ages ago, well before I figured out how relativity really works. http://www.ted.com/conversations/13951/the_proper_theory_of_relativit.html I didn't realise though until I reached the end that I'd been using this all along and that's how I knew something was wrong. (:

    Aug 28 2012: And... What if relativity... Is nonsense, and matter is expanding creating the illusion of gravity? Or, the concept of the ether still holds water, in a new form. I do like the fact that you proved that energy and matter are the same thing here though... One vibrates with gravity, one does not. I mean, for one space is bent, for one it isn't... Wait a second.

      Sep 10 2012: Relativity is not nonsense. General relativity is but once you fully grasp special relativity you realise that it couldn't possibly work any other way. Is soo beautiful. It can describe gravity properly as well purely and simply by viewing inertial paths through spacetime as physically equivalent to curved paths in flat spacetime, also known as acceleration and it removes the singularities from relativity and makes it compatible with quantum mechanics. It's that good.

      Aug 26 2012: What? Reverse the mass? I'm saying that if you view an object as following a straight line through curved spacetime as in general relativity it's no different than viewing it as following a curved path in flat spacetime, which is acceleration in special relativity. It would mean that you can't reach the event horizon of a black hole because that would be the equivalent of reaching the speed of light. Our understanding of the universe breaks down at singularities because they don't really exist. A freely falling observer is the equivalent to an accelerating observer in flat spacetime and they feel the acceleration as tidal force. That's why you can never see an object reaching an event horizon.

        Aug 27 2012: I interpreted your words "reverse everything within a system" to mean reverse everything within a system. Mass is part of a system so I am asking how to reverse the mass of an object. Where did I go wrong?

          Aug 27 2012: Mass has no direction so reversing it has no meaning.

          Aug 28 2012: In formulating a question that doesn't make sense. Mass is a value. You might as well ask be what happens when you reverse the colour orange or the letter c. The opposite of matter is anti-matter and the mass, and everything else stays the same.

        Aug 28 2012: I disagree that "the mass, and everything else stays the same."
        Negative mass is a hypothetical concept of matter whose mass is of opposite sign to the mass of normal matter. Such matter would violate one or more energy conditions and show some strange properties, stemming from the ambiguity as to whether attraction should refer to force or the oppositely oriented acceleration for negative mass. It is used in certain speculative theories, such as on the construction of wormholes. The closest known real representative of such exotic matter is a region of pseudo-negative pressure density produced by the Casimir effect. Ain't Wikipedia grand?

          Aug 28 2012: The opposite of matter isn't dark/negative matter, it's anti-matter. Gravity is still an attractive force when you run time backwards. All forms of matter attract.

    Aug 26 2012: Thank you for helping me understand why gravity is called the weak force. That explains much. I've often wondered, but never knew I hadn't asked the question correctly.

      Aug 26 2012: Wait, what? I have been told there are four (4) forces which account for all motion. . . One is Gravity; another is Electro-magnetic; then there is the Strong force; and finally the Weak force.

        Aug 26 2012: Sorry I misspoke. Gravity is the weakest force, not the weak force.

        Aug 27 2012: Of course now we potentially have a Higg's interaction as well so Five fundamental forces.
