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.

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?
Ethan Siegel: How we can get a universe from nothing?
Siegel: In order for inflation to end, that energy has to get converted into matter and radiation. The evidence strongly points to that happening some 13.8 billion years ago.
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…
New Scientist: Our understanding of the cosmos is “seriously wrong”
But don’t fret that a better understanding of the universe will leave entertaining crackpots out in the cold. Won’t happen. Can’t. Ethan Siegel explains why, in part.
Continuing efforts to erase the beginning of time
It’s quite clear that Siegel’s objection to the idea of a beginning to the universe is philosophical. Most of the nonsense one hears, generally, can be traced to unwillingness to admit that.
Should we call the Pauli Exclusion Principle quantum fine-tuning?
Absent the Principle, says astrophysicist Ethan Siegel, “most horrifically, carbon-based organic compounds — the building blocks of all life as we know it — would be an impossibility for us.”
In this version of the multiverse, you are unique
But wait! There might be an infinity of multiverses in which you are not unique. This is the only one in which your head has not exploded.
At Forbes: Cosmology’s crisis is merely “manufactured misunderstandings”
An astrophysicist dismisses the concerns as “ideologically-driven diatribes.”
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.
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.
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.
Uses and misuses of the Anthropic Principle
Theories multiply because the facts favor fine-tuning of the universe.
At Forbes: The real reason we haven’t found dark matter
According to astrophysicist Ethan Siegel: Personally, I don’t expect these direct detection attempts to be successful; we’re stabbing in the dark hoping we hit something, and there are little-to-no good reasons for dark matter to be in these ranges. But it’s what we could see, so we go for it. If we find it, Nobel Read More…
