Dark energy may be less energetic than previously thought

This is interesting.  Astronomers discovered dark energy, the energy causing the rate of expansion rate of the universe to speed up, by looking at large numbers of Type 1a supernovae. Type 1a supernovae are white dwarfs (collapsed stars after their … Continue reading

The movie ‘Interstellar’ and wormholes

The other day, I did a post on interstellar exploration which linked to one by Sten Odenwald on the problems with interstellar travel.  Well, he posted some follow-up remarks, expressing some surprise at the response, doubling down on the aspects of the limitations of … Continue reading

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 … Continue reading

Biology uses quantum effects.

When I first saw this article by Jim Al-Khalili and Johnjoe McFadden, my skeptical reflex kicked and I was, well, skeptical.  Often when quantum mechanics gets mentioned with biology, it’s questionable material.  But I’ve seen enough of Al-Khalili’s other work, and as … Continue reading

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 … Continue reading

Cosmic inflation appears to have shifted from settled science back to speculation

You can get background on what I’m talking about in this post here and here. Probably the best thing to do is let the experts weigh in on this. Planck team measurement consistent with our (Flauger et al.) estimates and … Continue reading

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 … Continue reading
