Here’s Ethan Siegel’s explanation, supplemented by many charts, graphs, and photos:
The true fact of the matter is that, observationally, dark energy is behaving as though it’s a form of energy inherent to the fabric of space itself. WFIRST, NASA’s flagship astrophysics mission of the 2020s (after James Webb), should allow us to reduce the measured constraints on w down to the 1-or-2% level. If it still looks indistinguishable from a cosmological constant (with w = -1) then, we’ll have no choice but to reckon with the quantum vacuum itself.
Why does empty space have the properties that it does? Why is the zero-point energy of the fabric of the Universe a positive, non-zero value? And why does dark energy have the behavior we observe it to have, rather than any other?
There are an infinite number of models we can cook up to describe what we see, but the simplest model — of a non-zero cosmological constant — requires no additions or modifications to match the data. Until we make progress on understanding the quantum vacuum itself, dark energy will remain the biggest unsolved puzzle in all of modern theoretical physics.

Well, it keeps cosmology writable and cosmologists in business.

SPIRAL cosmological redshift (CR) hypothesis and model –
explains why simple science attests there is no required, so no missing, dark energy and dark matter. SPIRAL ha the added advantage of predicting the CR and the increase of CR w/ distance, rather than having to react to that, as does SCM-LDM.

For once, I agree with Siegel. Understanding the composition of the vacuum is essential to shedding a revealing light on many mysteries of physics. If physicists truly understood motion, they would realize that we exist in a vast 4-dimensional lattice of energetic particles (photons) without which nothing could move. Once you understand the true cause of inertial motion, the scales fall from your eyes and you suddenly know that there is no accelerated expansion of the universe and there is no need for dark matter either. This understanding will come only after a radical paradigm shift in fundamental physics. It’s coming.
as to, “dark energy will remain the biggest unsolved puzzle in all of modern theoretical physics”. That reminds me of this video from Dr. Hugh Ross,
In the preceding video Dr. Ross mentions a paper, by atheistic astrophysicists studying the 1 in 10^120 fine tuning of dark energy, in which they honestly confessed that, “Arranging the universe as we think it is arranged would have required a miracle.,,,” Of course that ‘miracle’ is unacceptable for them so their solution was to try to claim that “we don’t live in a universe with a true cosmological constant”.
Although they tried to claim that “we don’t live in a universe with a true cosmological constant”, here are the 9 lines of evidence that Dr. Ross mentioned in his video which came out shortly after the preceding paper was listed as a preprint on the Los Alamos’s website. Evidences which made Dyson, Kleban and Susskind pull their paper from consideration,,,
In the last several years, astronomers have added seven additional lines of observational evidence confirming the reality of the finely tuned cosmological constant, bringing the total to sixteen. These seven are:
In the video Dr. Ross also mentions several verses in the bible that speak of God ‘stretching out the heavens’. (Job 9:8; Isaiah 40:22; Isaiah 44:24; Isaiah 48:13; Zechariah 12:1; Psalm 104:2; Isaiah 42:5; Isaiah 45:12; Isaiah 51:13; Jeremiah 51:15; Jeremiah 10:12.)
The following verse, since it offhandedly makes reference to Jesus walking on the sea, is my favorite out of the group of verses:
Of related interest, , another major problem in trying to unify quantum mechanics and general relativity is that when theorists try to combine the two theories, then the resulting theory predicts that spacetime, atoms, and the universe itself should all be literally torn apart. Here are a few references that get this point across.
Yet since both quantum mechanics and general relativity are both tested to extreme levels of precision, and we can thus have a high level of confidence that both theories are true descriptions of reality
,,, and since Godel’s incompleteness theorem requires something to be ‘outside the circle’ of mathematics in order to explain why the mathematics that describe reality might be true in the first place,
,,, then it is fairly safe to assume that something very powerful must be holding the universe together. ,,, For the Christian this should not be surprising. Two thousand years ago, Christianity predicted that in him all things hold together.
Also of related note, when we rightly allow the Agent causality of God ‘back’ into physics, as the Christian founders of modern science originally envisioned,,,, (Isaac Newton, Michael Faraday, James Clerk Maxwell, and Max Planck, to name a few of the Christian founders),,, and as quantum mechanics itself now empirically demands (with the closing of the free will loophole by Anton Zeilinger and company), by rightly allowing the Agent causality of God ‘back’ into physics then that provides us with a very plausible resolution for the much sought after ‘theory of everything’ in that Christ’s resurrection from the dead provides an empirically backed reconciliation, via the Shroud of Turin, between quantum mechanics and general relativity into the much sought after ‘Theory of Everything”. Here are a few posts where I lay out and defend some of the evidence for that claim:
