And it is easy to see why it happened, Rebel Science.
While we should not blame Einstein, it does start with Einstein.
Instead of expressing GR on matter, Einstein expresses it upward, with spacetime. He could not find the material foundation.
There are four motions the Earth is involved in. Three are gravity based, one is not.
* Earth's gravity and Earth's spin
* Solar System's gravity and Earth's revolution
* Milky Way's gravity and Earth dancing along in the circular motion
* Milky Way's speeding away from where it all started and Earth tagging along
This fourth motion is the fastest motion we are involved in. It is the only one that is NOT based on gravity.
That fourth motion is still solidly based on the catapulting motion produced during the materialization process; simply nothing has stopped it.
Mercury's peculiar behavior cannot be explained fully by gravity, because the Milky Way is also involved in this fastest speed. So it is not spacetime, it is the catapulting motion that adjusts Mercury's behavior this close to the Sun.
This is part of the Big Whisper model (The Big Bang model but then told correctly).

So when physicists took Einstein's theory and put his airy delivery as the foundation of science, they incorporated a flaw at the foundation of science. Einstein objected, to no avail. We have a flawed Big Bang model; we have a flawed Black Hole model.
