Why would I want to make up things that are supported by simple, visible evidence? The light from billions of galaxies shows that atoms are always changing themselves relationally. Not a single ancient galaxies shines with the light frequencies of modern atoms and the differences are often associated with distance (the past).
Lets be brutally frank about Einstein's theory. He imagined that the vacuum of space time is bent by the Sun and the earth follows the local bent rails in the vacuum. No one has ever detected a shred of visible evidence for space time nor has anyone isolated or directly detected any gravity. Both Einstein and Newton believed that static matter does enormous amounts of work bending the path of the Earth without changing anything about itself. This is nothing but a mathematical version of perpetual motion.
It is much simpler to observe that atoms are always changing their light frequencies and the orbits in countless galaxies continue to accelerate out, billions of galaxies intrinsically growing into huge growth spirals, as the properties of all matter visibly change. What causes gravity has never been isolated but the fact that atoms keep on accelerating their light clocks as orbits also accelerate in defiance of every law of physics should tell us at least that gravity is not a perpetual motion effect.
The scientific emperor is naked.
