Related to the post last week on quantum mechanics, here is a talk that got mentioned in the discussion thread. Warning: Carroll is a passionate advocate for the Many Worlds Interpretation, so don't expect a fair and balanced discussion. The video is about an hour long. http://www.youtube.com/watch?v=iXRLDatmbgA A couple of points. Carroll notes that we … Continue reading Sean Carroll on the Many Worlds Interpretation of quantum mechanics

Do all quantum trails inevitably lead to Everett?
I've been thinking lately about quantum physics, a topic that seems to attract all sorts of crazy speculation and intense controversy, which seems inevitable. Quantum mechanics challenges our deepest held most cherished beliefs about how reality works. If you study the quantum world and you don't come away deeply unsettled, then you simply haven't properly … Continue reading Do all quantum trails inevitably lead to Everett?
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
Sean Carroll makes the case for the Many-worlds interpretation of quantum mechanics
Sean Carroll has posted a passionate defense of the Many-world interpretation to quantum mechanics. I have often talked about the Many-Worlds or Everett approach to quantum mechanics — here’s an explanatory video, an excerpt from From Eternity to Here, and slides from a talk. But I don’t think I’ve ever explained as persuasively as possible why I think it’s the right approach. So that’s what … Continue reading Sean Carroll makes the case for the Many-worlds interpretation of quantum mechanics
A debate on quantum mechanics interpretations
"Anyone who is not shocked by quantum theory has not understood it." --Niels Bohr "If you think you understand quantum mechanics, you don't understand quantum mechanics." --Richard Feynman Quantum mechanics are utterly bizarre. Quantum particles behave like spread out waves, until their position is measured, when they suddenly behave like a particle with definite position. The … Continue reading A debate on quantum mechanics interpretations
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
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
Time to ditch falsifiability?
Related to my last two posts, and our discussion, Sean Carroll turned in an answer to the "What Scientific Ideas Are Ready for Retirement?" His answer? Falsifiability. Modern physics stretches into realms far removed from everyday experience, and sometimes the connection to experiment becomes tenuous at best. String theory and other approaches to quantum gravity … Continue reading Time to ditch falsifiability?
