Einstein’s general relativity in plain English
SEPTEMBER 15, 2021
How to understand Einstein’s equation for general relativity
Mathematically, it is a monster, but we can understand it in plain English
/ by Ethan Siegel /
https://bigthink.com/starts-with-a-bang/einstein-general-theory-relativity-equation/?fbclid=IwAR2zvMEL-kGl3GWw52vHZFfBxLJ2mhMIraXMQzg3tbasXbKuu7YFSpsDYao
------------------------
1 - Gravitation in Newtonian terms:
everything in the universe that has a mass attracts other mass
2 - Gravitation in Einstein’s terms:
single gravity masses (as Sun's) change the flat surface of the
cosmic vacuum and therefore quanta light change their straight travel
(we observe curviature of the cosmic spacetime)

About Einstein's General Relativity theory.
This equation describes that the curvature of an absolute 4D space-time (the flat cosmic vacuum)
depends on gravity matter ( rotational) and energy. On the left of equation is an absolute
4D space-time (flat cosmic vacuum) . . . on the right of equation is gravity matter ( rotational)
and energy . . . the spacetime (and light) curvature depends on quantities of gravity matter.
Without gravity matter the cosmic vacuum (an absolute 4D spacetime) is flat, homogeneous,
isotropic, symmetric and very cold (T=0K) continuum.
# ''Henceforth /gravity/ space by itself, and /gravity/ time by itself, are doomed to fade away
into mere shadows, and only a kind of union of the two / only the cosmic vacuum has space-time unity /
will preserve an independent reality.'' / Hermann Minkowski /
