Brian Green explains why "Einstein's greatest blunder explains one of the greatest scientific revelations" here
https://www.youtube.com/watch?v=QcJTKKCtAiI"Brian Greene, Columbia University physicist explains how today's physicists and mathematicians use an Einsteinian formula to explain the universe that Einstein himself originally thought was false.
Following is a transcript of the video.
The amazing thing is that blunder in Einstein’s mind is something that we now believe describes the actual universe.
Einstein became Einstein really because of his discovery of the general theory of relativity in 1915. The core of it are the Einstein field equations. And that’s a set of equations that relate the curvature of spacetime to the amount of matter and energy moving through a region of spacetime.
Interesting when Einstein applied theses equations to the entire universe, he found a result that he wasn’t happy with. He found that the universe could not be static and unchanging. It had to be either stretching or contracting.
And he said, “no.” The universe is clearly static and eternal. So what did he do? He went back to the equations. Put in one more term. On the left hand side he put in lambda. Lambda is what’s called the cosmological constant. He called it the cosmological member. And what it does is it can kind of give an outward push that can stabilize the inward pull of gravity, resulting in a static universe. And then Einstein was happy. Right?
But then in 1929 we learn that the universe is expanding and Einstein says,
Ugh, I wish I would not have put that term in.
Because my equations predicted that the universe is expanding and I would have gotten there 12 years before the observations. Today the amazing thing is that blunder in Einstein’s mind is something that we now believe describes the actual universe.
Because when we found that the accelerated expansion is happening, we want something that can push everything apart. What can do that? Einstein’s cosmological constant pushes things apart. We employ a different value. A different number than Einstein would have thought. But the idea is exactly what Einstein came up with.
Even Einstein’s bad ideas wind up being pretty darn good."
Like he said in the video I linked to above, Einstein's original equation, that included Lambda, the cosmological Constant, turned out to be right and about equal to Dark Energy.
This article in Forbes explains it great and has some great graphs that show it clearly, over time.

I never attributed that to anybody else and I've never seen it attributed to anybody else. It's just something that occurred to me when I heard what Brian Green said about one of the greatest scientific revelations, ever, being what Einstein called his Greatest Blunder, supposedly. In any case, he removed Lambda from his original equation because otherwise it would have created a static universe.
It's the greatest fudge factor ever,
yet, now it turns out to fit with our current model of the universe. So he was right, just for the wrong reason.
The universe wasn't static.
But he knew it couldn't be, based upon what they could see at the time. Back then, 100 years ago, all they could see was our galaxy. They thought the size of the universe was the size of our Milky Way. Now we have multiple telescopes in space and super computers that can put together maps like this.
https://www.youtube.com/watch?v=rENyyRwxpHoThat can tell us exactly where we are in the universe, and where we're going, (towards the Great Attractor) and how fast, (1.4million MPH) and where our neighbors are moving. Now we see that all the galaxies in our neighborhood, are moving together, towards a great center, "The Great Attractor".
So not only is the galaxy Expanding, it's also converging on the same point in space, the Great Attractor.
That's the cosmological constant.
That's gravity.
That's what we call god.
Sagan's god.
“The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity.” Carl Sagan
No, but how about praying to the Great Attractor?
Or God Particle?
Or just God, short for God Particle, since it's more of a universal field responsible for creating everything that matters?
That probably doesn't matter either and doesn't change anything, but intention does.
Setting intentions.
I have a brother in law, who's like a brother to me, in the hospital right now going through Chemo Treatments for Leukemia. He is an atheist and my sister asked us to pray for him.
But who or what do I pray to? Nature?
That's what's killing him right now.
We're un-natural animals living in a world that is full of death and pain and suffering and we're trying to hang on as best we can. We radiate, medicate, operate and fight like hell to stay alive. We Crispr cells to operate on DNA to cure a whole litany of diseases. We spend millions to keep a working, family man alive on this miserable planet.
For what?
So my sister and their son can live in paradise of his own making, in a passive solar house on the side of a South facing clearing on a hill on a little island overlooking the sea and the mountains, not another human being in sight as far as the eye can see. Just trees, water, Volcanos and wildlife everywhere. Where he has built his sanctuary, his love letter to his wife and family, written in stone, carved out of the hillside, gardens full of the sweet fruit of his labors. A self sufficient life surrounded by nature, but protected from too much nature.
Too much exposure to the radiation, that will cook you daily, slowly. If you do not take shelter.
So back to what do I pray to on my Brother's behalf?
I pray to god, which to me is the same as nature, combined with science, combined with philosophy and Cosmology, mainly Einstein's cosmology, but updated to take into account, what we can see written in the sky and our DNA, thanks to space telescopes and electron microscopes and DNA testing.
