Einstein's Blunder

When Albert Einstein tweaked his newly invented equations of General Relativity in 1917, he had one goal in mind: to find a solution that described a closed, static, eternal universe. He therefore minted a new universal constant to make it work. After Hubble’s discovery of the expansion of the universe in 1929, Einstein reportedly declared it his “greatest blunder”. In 1998 observations of distant exploding stars brought Einstein’s "blunder" back into consideration: Einstein might have been right the first time around.

Brilliant lecture as always Professor Trotta.

Very clear and understandable and I’m Scottish (where English is articulated properly) ;-)

EinsteinBranDicke I believe. Hubble Doppler is artifact of the curvature of spacetime. Cmb is surface of visible universe but nothing more.

If Einstein was"right the first time around" then we should be living in a "closed, static, eternal universe" instead of an accelerating expanding one...

[KaliFissure]

And we should consider applying a thixotropic fluid rather than a perfect fluid in the Friedmann matrix. Give it the same tweak that relativity gave Newtonian gravity.

I sort of think that thixotropy of space is the fundamental cause of gravity. If singular membrane as density increases AND viscosity goes down then the local surface is drawn towards high density regions, rather than dragged along. And gravity is that, movement towards energy density.

I wish I could understand your English better 😩
