| Re: When Einstein's 'curvature of space-time' is a Geodesic Straight Line (illustrate
My question about GR is this: Exactly what is the "stuff" called "mass"/"energy", and by what mechanism does "it" induce curvature to the fabric of spacetime?
"Mass" (inertia) is a property of "stuff" which causes it to "resist" any change in velocity. The more "massive" a "thing", the more "energy" must be applied to "it" to alter "its" motion.
G = 8 * pi * T.
The "G" tensor on the left side is purely geometric (space-time). The "T" tensor on the right is "stuff" (mass/energy). Sometimes a "cosmological constant" term is thrown in as a "fudge factor".
I believe Einstein refered to the geometry part (space-time) as "gold" and the material part (mass-energy) as "wood". I think it's time to turn the wood into gold.
Other equations include "E = hf" and "p = h/lambda", where f and lambda are geometric in nature, while E and p are material. Planck's constant "h" is a factor thrown in to "convert" the wood into gold, but what is the actual "mechanism" for h?
E/m = c^2
F/m = d^2*x / dt^2 (= a)  |
