How Are Neutrino Flavors Different ? Maybe There Is Only Vanilla . . .
Neutrinos are fundamental particles, more closely related to Electrons than Neutrons because they are not made up of smaller particles (Neutrons are made up of 3 Quarks). Here are some odd things about Neutrinos. 1. All three flavors (types) of … Continue reading

Elusive Dark Matter Idea Evaporating
NewScientist reports that “NASA’s FERMI satellite has confirmed a previous hint that there is more antimatter than expected coming from space. The bad news is that the result strongly almost certainly rules out Dark Matter as the source.”

Higgs Boson – Imaginary Particle Remains Science Fiction – Big Bang Weakens Further
The voice you hear getting louder is Brünnhilde practicing Götterdämmerung. Thats because the search is all but over for “the most sought-after particle in modern physics” – the Higgs Boson. Update: In March 2013, while there are a few loose … Continue reading
Universe Maps (inspire look for our nearest non-solar planet)
Here’s a very good set of maps of our Universe. It starts with maps of our solar system, then, in steps, it covers larger and larger volumes of space. Here you go — “Map of Our Universe”

Ethan Siegel Makes Science Errors, Corrects One
(Update: July 20, 2011 – Today Mr. Siegel corrected his article where it had wrongly claimed my article had quoted Professor P.J.E. Peebles “out of context.”) While Ethan Siegel generally does a good job illuminating science, he recently wrote a … Continue reading

Article on Big Bang’s Inadequate Definition Disputed – But Article Emerges Unscathed
I just found a critique by Ethan Siegel implying that there is some flaw in my article explaining Big Bang’s lack of an adequate scientific definition and hypothesis (titled “International Astronomical Union has no Definition for Big Bang“). While flattering … Continue reading
