And, as Ethan Seigel goes on to say at Big Think, “Even with all the physics we know, we have no idea how to calculate what it ought to be.”
Here in our expanding Universe, ultra-distant objects aren’t just speeding away from us, the rate at which they’re speeding away is increasing: teaching us that the Universe is accelerating. When we examine how the Universe is accelerating, we find that it’s behaving as though the Universe is filled with some sort of energy inherent to space: dark energy, or a cosmological constant. But theoretically, we have no idea how to calculate what the value of dark energy ought to be. Its extremely small but non-zero value remains a tremendous puzzle in fundamental physics.

Well, that’s the assured results of modern science for you…
Experimental physicist Rob Sheldon kindly writes to say, “As I’ve said before, Siegel is a mouthpiece of the status quo, which includes virtual particles, exotic dark mattter, dark energy, and inflation. As many have pointed out, there’s a host of contradictory data that deny the existence of all four. Yet like the four horsemen of the apocalypse, they rampage through physics destroying both experiment and theory, both funding and graduate students, our present and future. If you think our politics has collectively lost its mind, so have our physicists.”
Fair cop?
