"In the late '90s, more observations showed that the universe was actually accelerating in its expansion. Now, the standard theory of GR did not account for this, but theorists found that, by putting a constant back in the equations for this expanding universe in terms of GR, the acceleration of the expansion of the universe could indeed be modelled."

An accelerating universe is not corroborate with a big bang beginning. Moreover, the 'original explosion' has been 'adusted' to an expanding universe with no center, which is what the Cosmo Constant - the opposite vector of impelling gravity - entails; this includes the unexpectedly discovered
acceleration of the expansion.
The year he died - 1955, Einstein was back to working toward reinstatement of his 'biggest blunder' - abandoned cosmological constant and the Unified Field theory.
