Theoretical Physicist: Can’t Avoid a Beginning for Our Universe

Recent shakeups from the James Webb Space Telescope images invite fundamental questions like, Does the universe have a beginning?

The recent flutter over whether the James Webb Space Telescope’s data stream is a plus or a minus for the Big Bang and the Standard Model of the universe touched on some interesting cosmological issues. The Big Bang and the Standard Model support the assumption that our universe is finite and had a beginning. Could it have been eternal — with an infinite past instead of a beginning? The trouble is, as we saw last Saturday, when we try to apply concepts like infinity — typically used in mathematics — to the physical world, the basis of reality can collapse into absurdity. The world science observes seems to be finite; time starts at a certain point, flows in one direction,…

James Webb Space Telescope Shows Big Bang Didn’t Happen? Wait…

The unexpected new data coming back from the telescope are inspiring panic among astronomers

Physicist Eric J. Lerner comes to the point: To everyone who sees them, the new James Webb Space Telescope (JWST) images of the cosmos are beautifully awe-inspiring. But to most professional astronomers and cosmologists, they are also extremely surprising—not at all what was predicted by theory. In the flood of technical astronomical papers published online since July 12, the authors report again and again that the images show surprisingly many galaxies, galaxies that are surprisingly smooth, surprisingly small and surprisingly old. Lots of surprises, and not necessarily pleasant ones. One paper’s title begins with the candid exclamation: “Panic!” Why do the JWST’s images inspire panic among cosmologists? And what theory’s predictions are they contradicting? The papers don’t actually say. The…
