New interpretation of quantum physics: Many Interacting Worlds

There's a new interpretation of quantum mechanics: Scientists propose existence and interaction of parallel worlds: Many Interacting Worlds theory challenges foundations of quantum science -- ScienceDaily. This new interpretation appears to be similar to the MWI (Many Worlds Interpretation) where quantum superpositions don't collapse, but spread, creating what amounts to new universes.  However, in this theory, … Continue reading New interpretation of quantum physics: Many Interacting Worlds →

Multiverse theories: “meta-cosmology”?

Marianne Freiberger reports on a discussion she had with Bernard Carr on whether or not multiverse theories are science.  He has a suggestion for how we should classify these theories. With the possibility for indirect evidence in the future, maybe we shouldn't dismiss the multiverse as mere speculation, especially since it has many features that are … Continue reading Multiverse theories: “meta-cosmology”? →

New theory could be an alternative to the multiverse

It seems like there have been a number articles recently talking about the soul searching currently going on in the Physics community over the failure of the LHC to find evidence for super-symmetry (at least so far), a theory that had a lot of theoretical work resting on it.  This article discuses that and a new … Continue reading New theory could be an alternative to the multiverse →

Pseudophysics: The New High Priesthood

Wow.  Somewhat in balance to yesterday's reblog of part one of Coel Hellier's post defending multiverse theories as scientific, here's Amir Aczel skewering many of the proponents of multiverses and other untestable cosmological theories.  He takes aim at Brian Greene, Max Tegmark, Lawrence Krauss, and others, for presenting metaphysical assertions as science. The universe is a marvelous … Continue reading Pseudophysics: The New High Priesthood →

Max Tegmark and MinutePhysics on the mathematical universe

This is a subject that we've discussed repeatedly here, so I thought you might find Tegmark's narration of this video interesting. http://www.youtube.com/watch?v=HGG4HmlotJE I'm pretty sure that mathematics are not only something humans created, that they are based on relations we observe in the world, but beyond that, I remain largely agnostic on the Mathematical Universe Hypothesis … Continue reading Max Tegmark and MinutePhysics on the mathematical universe →

Quantum twist could kill off the multiverse, and Boltzmann brains

THE multiverse is dead, long live the multiverse. A radical new way of looking at quantum mechanics suggests that even the multiverse will come to an end. A popular view of the multiverse says that our universe is just one of an ever-inflating multitude of discrete "bubble" universes. These bubbles are eternally budding off new … Continue reading Quantum twist could kill off the multiverse, and Boltzmann brains →

Tegmark’s Mathematical Universe Hypothesis

I recently read Max Tegmark’s latest book, ‘Our Mathematical Universe‘, about his views on multiverses and the ultimate nature of reality.  This is the fourth and final post in a series on the concepts and views he covers in the book. The previous entries were: Tegmark’s Level I Multiverse: infinite space Tegmark’s Level II Multiverse: bubble universes … Continue reading Tegmark’s Mathematical Universe Hypothesis →

Tegmark’s Level III Multiverse: The many worlds interpretation of quantum mechanics

  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 third in a series of posts on the concepts and views he covers in the book.   The previous entries are: Tegmark’s Level I Multiverse: infinite space Tegmark’s Level II Multiverse: bubble universes Tegmark … Continue reading Tegmark’s Level III Multiverse: The many worlds interpretation of quantum mechanics →
