How the biggest Einstein’s blunder may recently be turned out to be right

How the biggest Einstein’s blunder may recently be turned out to be right 

It is well known that the cosmological constant that Einstein introduced 100-years ago, in his equations (in the context of the general relativity theory [general_relativity_theory] "GTR") was one of the most important unsolved issues of physics, which had haunted scientists for a century. Now it seems, however, that the issue has been resolved or, in any case, there is a great chance of it being driven for the solution. 

So let's see how things worked. The issue began when a century ago (roughly) Einstein published his equations, which eventually constituted the framework of the GTR. These equations explain how matter and #energy bend space-time to create gravitational force. But at that time, all the scientists, including Einstein, consented to a stationary universe with unchanged the total intra-galactic space. 

When Einstein applied the GTR, a non-static universe (in dilation or contraction) arose. Einstein aiming to impose the above mentioned scientific belief about the stability of the universe, on the universe model of the GRT, invented the cosmic constant. 

A few years later, Hubble noticed that the light from the remote galaxies was revealing that all of them were moving away from each other. It was the discovery that the universe is not static, but expanding. Einstein was persuaded thus removed the cosmological constant from his equations since it was no longer necessary to explain the expansion of the universe. Things came up to such a point that Einstein himself confessed that the introduction of the cosmological constant was perhaps his greatest blunder... 

Much later, in 1998, the astronomical observations of remote supernovae (the self-destructing stars) showed that the universe not only expands but the expansion is accelerated. A conundrum? No, for the scientists, who named the phenomenon dark energy [dark_energy]. Why? Because its true texture remains a mystery. 

By a twist of fate, scientists brought back Einstein's cosmological constant, this time to take into account dark energy. Thus, in the current accepted standard cosmological model, known as L-CDM [ΛCDM] (Lambda CDM), the cosmological constant was replaced by dark energy. 

Just a month before, a Swiss scientist, Lucas Lombriser, published a paper through which, no more and no less, a new way of exploiting Einstein's equations is presented, towards estimation of the value of the restored cosmological constant. 

It is comforting that, in the Lombriser’s view, the value of the cosmological constant approximates the observed value. Hence the conclusion of the title, i.e. that the greatest blunder of Einstein may be very close to being turned out to be right...
