Some stars seem to be defying the known laws of physics; others are found to produce specific rare elements when they collide

In our universe: Researchers are finding more evidence that colliding neutron stars forge not only gold but strontium, lanthanum, and cerium. They expect to discover more rare elements in the debris as well. (Universe Today, October 29, 2022) At this rate, we won’t run out. 😉 The paper is open access. When neutron stars collide: Speaking of stars, some seem to be defying the known laws of physics: “An international team of astrophysicists has made a puzzling discovery while analyzing certain star clusters. The finding challenges Newton’s laws of gravity, the researchers write in their publication. Instead, the observations are consistent with the predictions of an alternative theory of gravity. However, this is controversial among experts. The results have now…

Super-Earths that might have life, choosing life forms to take to Mars, and self-replicating robots…

A roundup from popular science news sources: ★ Are any super-Earths habitable? The largest single class of exoplanets discovered are super-Earths — bigger than Earth but smaller than Neptune, of which there are 1,577 confirmed discoveries. Some lie within the habitable zones — at least in principle — of their stars. Stony Brook astrophysicist Paul Sutter ponders the factors that go into determining how many of them are actually habitable, concluding, Perhaps the best candidate for a habitable super-Earth is LHS 1140b, which orbits a red dwarf star about 49 light-years from Earth. It’s about 60% wider than our planet but 6.48 times as massive. It orbits extremely close to its parent star — its orbital period is just 25…

Unexplained — Maybe Unexplainable — Numbers Control the Universe

For example, brilliant physicist Richard Feynman called 1/137, the fine structure constant, “a magic number that comes to us with no understanding by man”

In Carl Sagan’s Contact, the extraterrestrials embedded a message in the irrational number pi (the circumference of a circle divided by its radius). But some other numbers are critical to the structure of our universe too — and why they are critical does not make obvious sense. ➤ Perhaps the most fundamental and mysterious one is the fine structure constant of the universe: A seemingly harmless, random number with no units or dimensions has cropped up in so many places in physics and seems to control one of the most fundamental interactions in the universe. Its name is the fine-structure constant, and it’s a measure of the strength of the interaction between charged particles and the electromagnetic force. The current…

In an Infinity of Universes, Is Another You Reading This Article?

Maybe. But the recent science evidence is not especially encouraging

It is generally believed that the early universe widely inflated. So, reporting on a recent article submitted to Journal of Cosmology and Astroparticle Physics, Stony Brook astrophysicist Paul Sutter points out: First off, they found that eternal inflation wasn’t nearly as common as originally thought. Their explanation for why cosmologists had thought eternal inflation was generic was because those earlier cosmologists had studied only a limited set of models. They found that many viable inflation models (“viable” here means they didn’t obviously contradict observations) didn’t lead to an eternally inflating scenario. Paul Sutter, “How real is the multiverse?” at Space.com (December 16, 2021) Cosmologists line up on both sides: Prominent proponents of the multiverse have included well-known cosmologists such as Max Tegmark and…

Will Humans Ever Be Fully Replaceable by AI? Part 1

We must first determine, what is a person and what is the nature of the universe in which a person can exist?

The title question has been around for quite some time. In this discussion, I would like to take an ontological look at this question. What is the essential nature of being a person? To fully replace humans, what must AI machines become capable of? IF we want to consider the possibility of making humans obsolete, we need to know what is the essence of humanity? What is the ontological nature of a person? What characteristics define being a person? Even before we can address the essential nature of a person, we must identify the essential nature of the universe in which that person exists. What is the universe? How many dimensions does it have? Can the universe, or in it…
