I would draw a similar graph for FTL and knowledge of physics

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

Why is there something rather than nothing? Why would there be nothing?

Amanda Gefter has an interesting article at Nautilus looking at a somewhat perennial question: How can something come from nothing? The Bridge From Nowhere – Issue 16: Nothingness – Nautilus. In science, explanations are built of cause and effect. But if … Continue reading

The double slit experiment and the utter strangeness of quantum mechanics

Occasionally I remark about how illogical quantum mechanics is.  Sometimes people either insist that it is logical, or simply assert some simple explanation that shows they don’t really get how utterly strange this stuff is. This video of Jim Al-Khalili gives a … Continue reading

Does the Higgs boson actually exist?

I have to admit to wondering the same thing Nick talks about here.  Do any of these subatomic particles actually exist?  At least in the way we conventionally define “exist”?  We’re talking about entities that are sometimes a wave, sometimes … Continue reading
