I’m interested in learning more about galactic sheets and voids. Via testimonials, what books or texts discuss and expound on that topic?

Summary: Non-Mathematical Description of the Higgs Boson I seek a recommendation for a book written for the layman describing the physics of the Higgs boson and related topics. Books that I have found tend towards the history leading up to the discovery of the Higgs or biographies of Peter...

I seek current textbook recommendations for Modern Physics (Relativity, Quantum, Nuclear, Particles), upper undergraduate and graduate level, preferably that which are used at top-tier universities. Suggestions appreciated.

If you bothered to read the original post, I gave the publication, issue date, and page number. The article is not available online in the public domain. You will not be getting a link because there is no link.

A link to what? The original article online? It is behind a paywall, and unless you have a paid subscription to SA (I do) you won't be able to access it. Furthermore, I quoted the relevant paragraph. That's all there is to it. If you wish to read the full article, visit your local library.

In an article published in Scientific American, authors Adam Riess and Mario Livio wrote: Why negative pressure? I would think the pressure would be positive, thus making gravity repulsive.

I seek an explanation as to how a particle can be its own anti-particle. I would think the instant such a particle comes into existence, it would self-annihilate.

In the continental United States, all weather generally moves west to east or northeast, so your observation about the tip of the anvil does not surprise me. Nevertheless, thanks for sharing.

They might or could. They are typically near the top of the troposphere and flow westerly (west to east), but they may not be above an erupting volcano.

Thank you for the elaboration. It is most helpful.

Ah, yes! Gravitational redshift would explain it. Thank you.

Stephen Hawking, in his book Brief Answers to the Big Questions (2018), wrote the following (pp. 106-107): "If you fall towards a black hole feet first, gravity will pull harder on your feet than your head, because they are nearer the black hole. The result is that you will be stretched out...

Why do plumes of smoke or ash rise to a certain elevation and then appear flattened?

I always thought there were 92 natural elements, ending with atomic number 92 Uranium. However, I read where 94 are considered natural, to wit, 93 Neptunium and 94 Plutonium. Yet, the latter two need to be synthetically prepared. How can they be considered natural? Was 94 always the accepted...

I am a reader of the NYT and the WSJ, and I am interested in all things STEM qualitative or quantatative. The level of complexity is not important. If I do not know the mathematics, I will learn it to add to my repertoire. I have no idea what Virasoro algebras are, but I will soon find out...
