Space may be created by the interaction of individual quanta of gravity

If you're at a party, talking to someone, and the conversation is lagging, consider saying the title of this blog post: Space may be created by the interaction of individual quanta of gravity.  One of two things could happen, the first being most likely. Either the person will look at you like you're crazy and make an excuse to leave your company, or they'll reply, "That's so interesting. Tell me more." Having read physicist Carlo Rovelli's book, "Reality is Not What It Seems: The Journey to Quantum Gravity," I could talk some more about quantum gravity, but only a little…

“Reality is Not What It Seems,” a book by Carlo Rovelli

My new favorite book, until a fresh one arrives from Amazon, is Carlo Rovelli's Reality is Not What It Seems: The Journey to Quantum Gravity. Rovelli is an Italian theoretical physicist who, not surprisingly given the title of his book, is focused on resolving the mismatch between relativity theory and quantum mechanics. The key to doing this is to find a theory of gravity that is more fundamental than Einstein's general relativity, which describes gravity as the warping of space-time and isn't compatible with quantum mechanics. That's a fascinating subject, made more fascinating by Rovelli's impressive writing ability, albeit in…

Life is Simple, a fascinating book about Occam’s razor

I've been making my way through Johnjoe McFadden's book Life is Simple:How Occam's Razor Set Science Free and Shapes the Universe. It traces the history of science through the lens of Occam's razor. William of Occam, who was born in the late 13th century, is famous for favoring the simplest solutions in theology, science, and other areas of life. The book says, "Three centuries after his death, the French theologian Libert Froidmont coined the term "Occam's razor" to refer to William's preference for shaving away excess complexity." But contrary to how many people look upon Occam's razor, this doesn't mean…

I aspire to a radical embrace of reality

There's quite a bit to unpack in the title of this blog post, but I'll try to keep it fairly simple.  "Aspire" obviously means that a radical embrace of reality is something that I'd like to be able to do, but often this is more of a hope than an actuality for me. "Radical" refers to the fact that I, along with just about everybody else in the world, chooses to not embrace reality much of the time. Too disturbing. Too painful. Too whatever. So we cling to a form of unreality instead. If we always turned toward reality, that…

Calm acceptance of what is — my newest adage

I enjoy coming up with new pieces of advice that I can tell myself. They become temporary mantras, something I can repeat in my mind now and then to keep myself as centered as possible in an unpredictable world. Calm acceptance of what is. This is my newest adage.  I've always been impressed by people who can stay calm in stressful circumstances. Soldiers fighting in war. Emergency room doctors and nurses. Parents of a two year old having a temper tantrum. So many other examples of humans handling difficult situations with poise and competence. That requires a certain detachment from…

Enjoying religious stories is fine. Just realize they’re fiction.

As I've noted before on this blog, I'm a big believer in good stories. I enjoy reading fiction. I enjoy watching fiction.  It never fails to amaze me that I can be sitting in our bathtub every evening, nestled in hot water with a vaporizer full of quality Oregon marijuana, holding an escapist thriller book (I love Vince Flynn's Mitch Rapp novels; he's a CIA operative), getting excited about whether Rapp is going to succeed in his latest exploit -- while I know full well that Mitch Rapp is a creation of Flynn's imagination, or in the case of the…

We live in a world of imperfect realism

A few days ago I explained why I wasn't writing about an idea I had: Embrace what's real, not an ideal. I was planning to revisit that topic tonight. But this morning I read a fascinating chapter in David Chalmers' new book, Reality+: Virtual Worlds and the Problems of Philosophy.  The chapter, "Have we fallen from the Garden of Eden?," reflected the basic notion I had. That there's a marked difference between viewing life as it actually is, versus how it could ideally be. Chalmers starts off his chapter with a creative look at how science has changed the Eden-like…

Mind-body dualism almost certainly isn’t true, but it could be in a simulation

Are mind and body two different things, or one thing? Descartes, along with Eastern religions that view consciousness as immaterial, argue that mind and body belong to different realms, nonphysical and physical. A big problem with this view, of course, is that it's obvious that mind and body are intimately connected. I think, "Type I think," and voila, that's what happens. If mind and body are different, how could an immaterial mind control the physical fingers that tap out letters on my keyboard? And how is it that ingesting coffee, LSD, alcohol, or numerous other substances affects the mind, if…

If we’re in a simulation, its creator is our god

A few days ago I wrote about one of the central notions in David Chalmers' new book, "Reality+: Virtual Worlds and the Problems of Philosophy. Namely, that if we're in a simulation, our world is still real.  In this post I'll talk about a chapter in the book with a compelling title: Is God a hacker in the next universe up?  What I'm enjoying most about Reality+, aside from how clearly Chalmers writes and reasons, is how he integrates basic philosophical questions with the specific issue of us being in a simulation. Does God exist? The question has been asked…

Even if we’re in a simulation, our world is real

As computer simulations become more and more lifelike, the question could we be living in a simulation?  becomes more interesting. Especially to fans of The Matrix movies.  But also to philosophers, since Plato, Descartes, and many others have wondered whether this world that we assume is real, actually is. David Chalmers, a philosopher who is the codirector of the Center for Mind, Brain and Consciousness at New York University, has written a fascinating book: Reality+: Virtual Worlds and the Problems of Philosophy.  In an early chapter, Chalmers summarizes the central questions he addresses in the book, along with his one…

Does spacetime emerge from a more fundamental reality?

The title of this blog post is a question posed on the cover of the February 2022 issue of Scientific American. It refers to a story in the issue, "The Origins of Space and Time."  I enjoyed the story, even though it was difficult to understand.  Here's an image that encapsulates the two main approaches to figuring out what space and time (or as relativity theory puts it, spacetime) emerge from -- assuming they emerge from anything. So if you were expecting some explanation that could be fit, or crammed, into a religious or mystical worldview, expect again. Science of…

The best spiritual practice could be…nothing

Here's some thoughts about the value of basing your spiritual practice on... drumroll please... absolutely nothing. But I'll introduce this topic by sharing an anecdote. Yesterday I took our dog for a walk around the community lake near our rural property. A house is for sale that overlooks the lake. A woman and two children were walking down from the house toward the lake, seemingly because the family was looking into buying the house. A young boy came up to the fence that our dog and me were on the other side of. He pointed and said, "nice lake." Then…

Respect for facts is a great virtue

I'm a lover of facts. That's why I'm a hater of religion. Ah, but don't religions seek the truth? Not really. They claim to, but only in the sense that QAnon followers believe they're truth-seekers.  In each case, religion and QAnon, truth is viewed much more as a belief, as something they hope is the case, rather than as an aspect of objective reality. So facts are different from truth. There's lots of ways people define those two terms, as I learned by doing some Googling.  This article describes the difference quite clearly. A Fact and a Truth walk into…

Christmas is a good time to debunk all religious belief

Naturally Christianity comes to mind in December, since Christmas includes the word "Christ." But I view this time of year as an opportunity to remind myself, and others through this blog, of the absurdity of all religious belief.  Of course, it is only us atheists who look upon all religions as absurd. Since most people are religious, they view their faith as making good sense. It's those other religions that are absurd. To offer a few examples: -- Christians have no problem believing that Jesus was born of a virgin, walked on water, and came back from the dead. But…

Reason rules with God’s will, karma, and laws of nature

Having written about reason and rationality recently, here's some thoughts that came to mind (weird phrase, since where else would thoughts appear?) as I was musing about how people believe in God's will and karma as other-worldly explanations for why things happen as they do. It struck me that God's will and karma are appealing notions for many because they provide reasons for happenings that often aren't pleasant. Or are surprising. For example, I know someone who got stage 4 lung cancer even though she never smoked. Thankfully, she's doing quite well, even after several years have passed since the…

Why people with religious delusions do fine in everyday life

I've finished Steven Pinker's book, Rationality: What It Is, Why It Seems Scarce, Why It Matters. I enjoyed it, though some chapters were a bit tedious. The final chapters, though, held my interest. Here's what I liked most in the next to last chapter, "What's Wrong With People?" Meaning, why do so many people believe such crazy irrational stuff? It starts off with a great George Carlin quote. Tell people there's an invisible man in the sky who created the universe, and the vast majority will believe you. Tell them the paint is wet, and they have to touch it…

The chance that you know something others don’t is very small

After over fifty years of pursuing spirituality in one form or another, I've come to one firm conclusion. I'm nothing special. And neither are you. Nor is anybody else. Now, I'm not saying that everybody is the same. Obviously every person is different. We all have different thoughts, emotions, talents, likes and dislikes, appearance, and so on. What I mean is that we're all material beings living in this material world, to sort of quote Madonna.  So whatever we know about the world, almost certainly other people possess the same knowledge. Most of us like to think that in some…

Presumptions are necessary for reasoning to work

Almost everybody who has had a child -- that includes me -- knows how annoying it can be when they learn how to make "Why?" into a way to drive a parent crazy. You need to turn the TV off and go to bed.Why?Because it's late and you need to go to school tomorrow.Why do I need to go to school?So you can learn things.Why should I learn things? And so it goes, until the parent gets fed up and ends the discussion with "Because I said so! Go brush your teeth!" Andy Norman uses this sort of Why? reasoning…

“Moon” movie points to shocking non-supernatural realization

A year or so ago I watched "Moon" via Netflix. I guess at this point I need to enter an obligatory spoiler alert, in case anyone hasn't seen this 2009 movie and thinks they might want to see it without knowing a crucial plot element. This was an intriguing movie, though not super-entertaining. The acting was good, but not exceptional. What I distinctly remember was a shocking twist. There Sam Bell (played by Sam Rockwell) is, at a base on the moon where a mining operation is taking place. He's looking forward to returning home after a three-year solitary tour…
