Did Einstein actually predict that the universe is expanding ?

History

Einstein included the cosmological constant as a term in his field equations for general relativity because he was dissatisfied that otherwise his equations did not allow, apparently, for a static universe: gravity would cause a universe that was initially at dynamic equilibrium to contract. To counteract this possibility, Einstein added the cosmological constant.^[3] However, soon after Einstein developed his static theory, observations by Edwin Hubble indicated that the universe appears to be expanding; this was consistent with a cosmological solution to the original general relativity equations that had been found by the mathematician Friedmann, working on the Einstein equations of general relativity. Einstein reportedly referred to his failure to accept the validation of his equations—when they had predicted the expansion of the universe in theory, before it was demonstrated in observation of the cosmological redshift—as his "biggest blunder".

Wrong again!! Eisnteins equations predicted a dynamic universe.

 

But the beliefs of the day were that the universe was static. Einstein added the CC to maintain that static. This was, as Einstein claimed, his biggest blunder, when Hubble discovered the cosmological redshift...he failed to believe the predictions of his own theory.

 

 

But you see, Einstein never predicted the expansion with his theory. He predicted the exact opposite, a CONTRACTION, and  initially rejected an expansion (proposed by Friddman
), because he was too occupied to doctor his theory in order to comply with a static universe, -which was the belief of the time. That is not a scientific aproach, it is a totally pseudo-scientific aproach. And that is not a scientific theory, because it obviously contradicts itself. As, depending on the man who is solving the equations, it gives opposite results ! And btw, makes Einstein look a bit silly not being able so solve his own equations ! This is not the genius that I had in mind. 

 It is important to note that someone else predicted an expansion based on his theory, expansion which he rejected, and only after Hubble saw the redlight accepted. But this was his THIRD TRY. I wonder how many scientists are given so many shots to 'prove' their theories.

In the end Einsteins GR 'predicted' all possible states of the universe: contracting, static, and expanding ! So whatever state the universe was in, his theory could not be wrong ! Because Einstein simply changed the theory's outcome according to 'the beliefs of the time'.

Whining won't make any of your 'proposals' more compelling.

Denying evidence is not a good idea either.

And ignoring the maths --the fact that non-linear equations are generally impossible to solve-- is not the solution.  

Don't know what to make of the attempt to trash one of the most brilliant physicists in living memory.

In Australia we call it "tall poppy syndrome" most often used by scallywags with an agenda, and attempting to chop down the tallest poppy (top scientist) 🥱

If you can suggest he was corrupt and intellectually dishonest, you don't have to actually study his work. Huge time saver for the ignorant.
