Multiverse Cosmology Is Not a Good Argument Against God

Or against fine tuning of our universe. God could have created countless universes on various principles for a variety of reasons

Mathematics, Philosophy, Science

New Scientist’s executive editor Richard Webb, a “recovering particle physicist,” offers a look at the current state of the idea that there might be an infinity of universes out there. Why believe it? Mainly, it turns out, to avoid believing something else: Gods and their intelligent designs are less in the mainstream of scientific thought now, yet similar ideas about an optimal universe still trickle through cosmology. That is principally down to some mysterious numbers that determine its workings. Tot them all up in the standard models of particle physics and cosmology, and you end up with about 30 constants of nature – numbers like the strengths of the fundamental forces and the masses of elementary particles that our theories Read More ›

In Define information before you talk about it, neurosurgeon Michael Egnor interviewed engineering prof Robert J. Marks on the way information, not matter, shapes our world (October 28, 2021). In the first portion, Egnor and Marks discussed questions like: Why do two identical snowflakes seem more meaningful than one snowflake. Then they turned to the relationship between information and creativity. Is creativity a function of more information? Or is there more to it? And human intervention make any difference? Many questions arose during the discussion. Does Mount Rushmore have no more information than Mount Fuji? Does human intervention make a measurable difference? That’s specified complexity. Putting the idea of specified complexity to work, how do we measure meaningful information? How Read More ›

Why Just Anything Can’t Happen via Infinite Universes

We can see why not, using simple mathematical reasoning in this universe

Mathematics, Science

Can anything happen if there are an infinite number of universes each with an infinite number of possibilities in each? Can you be bald in one universe and fully haired in another? Can you have two eyeballs in this universe and three in another? The answer is no. In a nutshell, the reason is that some infinities are bigger than other infinities. (And this is not a claim like infinity plus one is bigger than infinity. Infinity plus one is still infinity.) The number of points on a line segment from, say zero to one, is a bigger infinity than the number of counting numbers {1,2,3,…}. We can label the infinite number of universes in the multiverse as universe #1, Read More ›

In the “Does God exist?” debate at Theology Unleashed between theist neurosurgeon Michael Egnor and atheist broadcaster Matt Dillahunty (September 17, 2021), we now look at questions from the audience on whether singularities are really a part of science and whether atheism is really a belief system that can make predictions. Readers may recall that the debate opened with Egnor explaining why, as former atheist, he became a theist. Then Dillahunty explained why, as a former theist, he became an atheist. Michael Egnor then made his opening argument, offering ten proofs for the existence of God. Matt Dillahunty responded in his own opening argument that the propositions were all unfalsifiable. When, in Section 4, it was Egnor’s turn to rebut Read More ›

In early, easily-mocked sci fi, a little green man points his raygun at an unsuspecting passerby and barks “Take me to your leader.” Fast forward: If the little green man didn’t have the technology to figure out who the leader was before landing, he certainly wouldn’t have the technology to get here. In any real-world scenario, we must assume that extraterrestrial intelligences are doing common sense logical things that we would do: Check Earth’s inhabitants out first by monitoring our communications. Some analysts have pointed out that there are places they could even hide technology in our solar system (Lagrange points, for example) with much less chance of being noticed.

Have you ever been in an online discussion where a vocal proponent confidently claimed that his opponent was the victim of the dreaded “Dunning–Kruger” effect? At Vox, Brian Resnick explains, “That’s where people of low ability — let’s say, those who fail to answer logic puzzles correctly — tend to unduly overestimate their abilities”: An obvious example people have been using lately to describe the Dunning-Kruger effect is President Donald Trump, whose confidence and bluster never wavers, despite his weak interest in and understanding of policy matters. But you don’t need to look to Trump to find an example of the Dunning-Kruger effect. You don’t even need to look at cable news. Brian Resnick, “An expert on human blind spots Read More ›

University College London cognitive neuroscientist Brian Butterworth, author of a forthcoming book, Can fish count? (Basic Books, 2022), reckons that, one way or another, in a modern urban society, we process about 16,000 numbers in an average day. Numbers create conceptual relationships between vastly different things. From the publisher’s introduction to his book, we learn, “The philosopher Bertrand Russell once observed that realizing that a pair of apples and the passage of two days could somehow both be represented by the concept we call “two” was one of the most astonishing discoveries anyone had ever made.” At The Scientist, Catherine Offord, discussing his work, offers a critical distinction between estimations of quantity and actual counting: “Our perception of quantity, separate Read More ›

COVID-19, Bayes’ Rule, and Simpson’s paradox

Israeli data, when studied carefully, confirm the effectiveness of COVID-19 vaccines

Mathematics, Medicine and Health

Israel has a very high COVID-19 vaccination rate and yet, on August 15, 2021, 58% of those Israelis hospitalized for COVID-19 were fully vaccinated — suggesting that vaccinations are ineffective or even harmful. This is a great example of two common statistical traps. The first is confusion about inverse probabilities. One hundred doctors were once asked this hypothetical question: In a routine examination, you find a lump in a female patient’s breast. In your experience, only 1 out of 100 such lumps turn out to be malignant, but, to be safe, you order a mammogram X-ray. If the lump is malignant, there is a 0.80 probability that the mammogram will identify it as malignant; if the lump is benign, there is a 0.90 probability that Read More ›

The war continues so here are some updates: Recently, three mathematicians who immigrated to the United States weighed in: The United States has been dominant in the mathematical sciences since the mass exodus of European scientists in the 1930s. Because mathematics is the basis of science—as well as virtually all major technological advances, including scientific computing, climate modelling, artificial intelligence, cybersecurity, and robotics—US leadership in math has supplied our country with an enormous strategic advantage.

Why Animals Can Count But Can’t Do Math

At The Conversation, psychology professor Silke Goebel offers some perspective on the differences between the way animals and small children process numbers and the way adults do. As a researcher in numerical cognition, she tries to focus on how brains process numbers. Her research shows that Humans and animals actually share some remarkable numerical abilities – helping them make smart decisions about where to feed and where to take shelter. But as soon as language enters the picture, humans begin outperforming animals, revealing how words and digits underpin our advanced mathematical world. Silke Goebel, “Why animals recognise numbers but only humans can do maths” at The Conversation (July 28, 2021) Essentially, she says, there are two different types of counting Read More ›

Albert Einstein, Jogalekar tells us, considered it a privilege to walk home with Gödel every day. Why?: In an exceptionally elegant essay, science writer Ashutosh Jogalekar (no stranger to controversy) talks about the huge difference Kurt Gödel (1906–1978) made by eliminating the idea that some single, simple explanation would put an end to all questioning about the nature of the universe in favor of some simple materialism. In a review of Stephen Budiansky’s biography of Gödel, Journey to the Edge of Reason (Harvard 2021), Jogalekar explains how Gödel dashed such hopes: In September 1930, a big conference was going to be organized in Königsberg. German mathematics had been harmed because of Germany’s instigation of the Great War, and Hilbert’s decency Read More ›

Is Our “Number Sense” Biology, Culture — or Something Else?

It’s a surprisingly controversial question with a — perhaps unsettling — answer

Mathematics, Philosophy of Mind

British science writer Philip Ball, author of How to Grow a Human, offers an even-handed account of a controversy on the origin of our ability to understand numbers (numeracy). Numeracy is the beginning of mathematics, the most abstract of all human pursuits. It isn’t possible to get very far in mathematics without some ability to abstract. Ball cites as an example the difference between 152 and 153. Many life forms, competing for a pile of food items, can distinguish between 2 and 3. But distinguishing between 152 and 153 clearly requires abstraction. It’s the same principle as the chiliagon, a geometric figure like a triangle except that it has 1000 sides. A triangle can be envisioned concretely. A chiliagon can Read More ›

The video game fraud he focuses on involved a gamer’s claim that he had finished a round of Minecraft in a little over 19 minutes, a feat he attributed, Ritchie tells us, to “an incredible stretch of good luck.” “Incredible” is the right choice of word here. “Dream,” as the player was known, later admitted — in the face of skepticism — that he had “inadvertently” left some software running that improved his game — thus disqualifying Read More ›

No Free Lunches: Bernoulli is Right, Keynes is Wrong

What the Big Bang teaches us about nothing

Mathematics, Science

Jacob Bernoulli made a now obvious observation about probability over three-and-a-half centuries ago: If nothing is known about the outcome of a random event, all outcomes can be assumed to be equally probable. Bernoulli’s Principle of Insufficient Reason (PrOIR) is commonly used. Throw a fair die. There are six outcomes, one for each face of the cube. The chance of getting five pips showing on the roll of a die is therefore one sixth. If a million lottery tickets are sold and you buy one ticket, the chances of winning are one in a million. This reasoning is intuitively obvious.  The assumption about the die is wrong if the die is loaded. But you don’t know that. You know nothing. So Bernoulli’s PrIOR Read More ›

Gödel Says God Exists and Proves It

Mathematics, Religion

Kurt Gödel, an intellectual giant of the 20th century, offered a mathematical proof that God exists. Those who suffer from math anxiety admire what the theorem (shown below) claims to do, but have absolutely no idea what it means. Our goal is to explain, in English, what Gödel’s existence of God proof says. Gödel’s proof shows the existence of God is a necessary truth. The idea behind the truth is not new and dates back to Saint Anselm of Canterbury (1033-1109). Great scientists and philosophers, including Descartes and Leibniz, have reconsidered and refined Anselm’s argument. Gödel appears to be the first, however, to present the argument using mathematical logic. Lexicography In any development of a mathematical theory, there are foundational axioms Read More ›
