David Deutsch’s version of many worlds

Schrodinger's cat in many worlds

I've written about the bizarre nature of quantum physics many times, providing a lightning primer back in May on three major interpretations: Copenhagen, pilot-wave, and many worlds.  The many worlds interpretation (MWI) is often summarily dismissed by people, often along with visceral shudders or high doses of outrage.  I understand the discomfort.  When I first … Continue reading David Deutsch’s version of many worlds

Sean Carroll’s Something Deeply Hidden

I'm just about finished reading Sean Carroll's Something Deeply Hidden.  I was going to wait to post this until I'd completely finished, but all I've got left is the appendix, I perceive that I've gotten through the main points, and discussion on the previous post is veering in this direction. As widely reported, Carroll is … Continue reading Sean Carroll’s Something Deeply Hidden

Einstein, Schrodinger, and the reluctance to give up hard determinism

Ethan Siegel on his Starts With a Bang blog has an interesting review of Paul Halpern's new book on Einstein and Schrodinger, and their refusal to allow the implications of quantum physics to dissuade them from idea that the universe is strictly deterministic.  It's an interesting post and one that I recommend reading in full. … Continue reading Einstein, Schrodinger, and the reluctance to give up hard determinism

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
