I recently finished reading Max Tegmark’s latest book, ‘Our Mathematical Universe‘, about his views on multiverses and the ultimate nature of reality. This is the second in a series of posts on the concepts and views he covers in the book. Tegmark postulates four levels of multiverse. In the first post of this series, I described Termark's Level I … Continue reading Tegmark’s Level II Multiverse: bubble universes

Tegmark’s Level I Multiverse: infinite space
I've just finished reading Max Tegmark's latest book, 'Our Mathematical Universe', about his views on multiverses and the ultimate nature of reality. This is the first in a series of posts that I plan to do on it. Tegmark postulates four levels of multiverse. This post is about the first, and simplest version, the Level I … Continue reading Tegmark’s Level I Multiverse: infinite space
The fine tuning “problem”
An interesting article byJonathan Borwein and David H. Bailey on why science needs philosophy. When renowned scientists now talk seriously about millions of multiverses, the old question “are we alone?” gets a whole new meaning. Our ever-expanding universe is incomprehensibly large – and its rate of growth is apparently accelerating – but if so it’s … Continue reading The fine tuning “problem”
How a Medieval Philosopher Dreamed Up the ‘Multiverse’ | Space.com
The idea that our universe may be just one among many out there has intrigued modern cosmologists for some time. But it looks like this "multiverse" concept might actually have appeared, albeit unintentionally, back in the Middle Ages. When scientists analyzed a 13th-century Latin text and applied modern mathematics to it, they found hints that … Continue reading How a Medieval Philosopher Dreamed Up the ‘Multiverse’ | Space.com

You say multiverse, I say galaxies
Corey Powell has an interesting post up on what he calls the Four Great Eras of Exploration. The first era was Galileo's discovery of the vastness of the universe, the second that stars were composed of chemical elements, and the third was Hubble's discovery of other galaxies. The fourth, and main topic of his post, … Continue reading You say multiverse, I say galaxies
When Classical Universes Collide, The Result is Quantum Mechanics, Say Physicists
I shared this on Twitter, but it occurred to me that, although I didn't have any particular comment to make on it, many of my non-Twitter readers might find it interesting. The strange behaviour of the quantum world is direct evidence of the interaction between our universe and many other classical universes, according to a … Continue reading When Classical Universes Collide, The Result is Quantum Mechanics, Say Physicists
Are Parallel Universes Unscientific Nonsense?
If you’re a multiverse skeptic, you should know that there are many potential weaknesses in the case for parallel universes, and I hope you’ll find my cataloging of these weaknesses below useful. To identify these weaknesses in the pro-multiverse arguments, we first need to review what the arguments are. via Are Parallel Universes Unscientific Nonsense? … Continue reading Are Parallel Universes Unscientific Nonsense?
The physics of the multiverse
Fellow blogger agrudzinsky shared this video in a comment, but I thought it was good enough to warrant a full post. http://www.youtube.com/watch?v=Ywn2Lz5zmYg I like the fact that he repeatedly states that these ideas have not been experimentally confirmed, and the wrap-up where he points out that physics is not philosophy (or at least it's not supposed to … Continue reading The physics of the multiverse
Why a Larger Multiverse Shouldn’t Make You Feel Small | Max Tegmark
The Higgs Boson was predicted with the same tool as the planet Neptune and the radio wave: with mathematics. Why does our universe seem so mathematical, and what does it mean? In my new book, Our Mathematical Universe, which comes out today, I argue that it means that our universe isn't just described by math, … Continue reading Why a Larger Multiverse Shouldn’t Make You Feel Small | Max Tegmark
