Forbes’ physics columnist Ethan Siegel can’t wait to get beyond the Big Bang

But doesn’t seem to have a ticket. So a mechanism that caused the Universe to come into existence with these properties already in place? But then what caused that mechanism? If a mechanism caused that mechanism, what in turn caused the previous mechanism? Siegel obviously wants to get past the idea of an actual beginning but orthodox science does not seem to allow that. Some religious propositions might suffice, of course, but he does not want to go there. Advice from readers? Read More ›

Ethan Siegel asks at Forbes, Did God create the universe?

Siegel makes an interesting comparison with, say, Sabine Hossenfelder. He does great graphics but to say that he is not a deep thinker is to shower him with imprudent praise. By contrast, we go on listening to Hossenfelder with great interest, whether the graphics are good or not. Read More ›

Ethan Siegel’s claim at Forbes: Why we’ll never exactly solve general relativity. Rob Sheldon responds

Not only is Ethan's profession about to get a major readjustment, but his attitude needs a readjustment as well. No longer can he and his colleagues hide in their ivory tower telling the world that we must leave the hard thinking to them. As many have already commented, the woke mobs are already at the gates.

In case you wondered why dark energy is “the biggest unsolved problem in the universe”

Ethan Siegel: 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? Read More ›

What elements of fine-tuning of our universe (vs. the multiverse) would pass this test of science truth?

Ethan Siegel: Even the most successful scientific theories imaginable will, by their very nature, have a limited range of validity. But we can theorize whatever we like, and when a new theory meets the following three criteria... Read More ›

At Forbes: Fine-tuning really is a problem for cosmology, about which nothing can be done

So here’s where it stands: They’re compelled to stumble and make up nonsense and the rest of us are compelled to support them, cheer them on, and accept the dismal outcome, forever if need be. Read More ›

Forbes’ cosmology commentator: Maybe we ARE alone

He goes through the usual potted history of life on Earth, omitting (they always do) to notice that the human mind is a quite different sort of development than, say, sexual reproduction or flight. It's the mind that prompts us to even ask questions about ET, yet no one has any idea what consciousness even is. Read More ›

An astrophysicist makes clear why a multiverse MUST exist

You should be suspicious of any science claim that could have been thought up as a sheer work of the imagination. The multiverse is just such a concept: Somewhere, everything and its opposite happens or doesn’t, in an infinity of infinities. No math needed. Read More ›
