[[Gravitation demystified]] that explains [[Einsteinian gravitation]] in terms of curvatures of space and time (while the spacetime is flat).

 

''"[[Gravitation demystified]]"'' explains [[Einsteinian gravitation]] in terms of curvatures of space and time (while assuming the spacetime being ''flat'' since the sum of two curvatures may come out as intinsically ''flat'', or [[Minkowski]] spacetime) explaining on its way the phenomenon of [[cosmological redshift]] as caused by the curvature of space coupled with the time (the time runing slower at the deep space galaxies roughly proportionally to distance, in fact exponentially slower).

 

The [[cosmological redshift]] was taken not long time ago for a sign that the universe is expanding. The project meant to prove that expansion of space is decelerating, to add credibility to the Big Bang hypohtesis (in agreement with John Archibald Wheeler's theory), showed that to the contrary, the universe seems to be expanding with accelerating expansion. <math>dH/dt=-H_o^2/2</math>, where <math>H</math> is Hubble "constant", <math>t</math> is our time, <math>H_o</math> is Hubble "constant" at <math>t=0</math>, which was just the acceleration predicted by Einsteinian gravitation as ''apparent'' accelerating expansion that should be observed if [[Einsteinian gravitation]] where a right theory. A billion dollar experiment that went wrong. Not for [[Einsteinian gravitation]] though.

 

However the Big Bang aficionados patched their theory with "[[dark energy]]" insisting that the universe is expanding because of this energy, faster and faster. Now they are looking for this energy in the universe while papers on [[Einsteinian gravitation]] aren't published in scientific journals.
