Dark Matter Missing in Milky Way and Nearby Galaxies – after thorough searches
Gigantic pillars of Big Bang are creaking and starting to collapse like colossal dominoes. These are tumultuous times in Cosmology. Recently I described how the “The voice you hear getting louder is Brünnhilde practicing Götterdämmerung” in describing the fruitless and … Continue reading
Your Cosmology Hypotheses Invited

Electron No Longer a Fundamental Particle
Amazing news: Researchers in Switzerland split an Electron into two smaller particles – a “Spinon” and an “Orbitron;” meaning they have separated the spin and the orbit properties of an Electron. Until now, standard physics generally accepted that an Electron … Continue reading

Astronomical Image Enhancements
It is not always made clear that astronomical images are altered or “cleaned-up” before we see them. You know the colors of gasses and dust are “adjusted” so we can more easily see different astrophysical phenomena. You might be surprised … Continue reading

“Perfect” Light Speed available with miniscule adjustment to the Second or the Meter Definition
Currently the speed of light in a vacuum is just a hair under 300,000 kilometers per second (more precisely 299,792,458 kps). Because the speed of light (known as “c” to mathematicians and physicists) does not exactly match 300,000 kilometers per … Continue reading

Is Dark Matter “The Emperor’s New Clothes?”
“To claim that you have simulated the Big Bang is like a schoolboy claiming after winning a high jump medal that he is close to jumping on to the moon.” Esteemed Cosmologist Professor Emeritus Jayant V. Narlikar reports from a … Continue reading

Must Faster-than Light Neutrinos Cause Cerenkov Radiation?
A recent criticism of the apparently Faster-than-light (FTL) Neutrinos inspiring a lot of discussion is the claim that if Neutrinos are going FTL – they must cause Cerenkov radiation. Why? That doesn’t make sense. How would they do that? Cherenkov … Continue reading

Observation of two early yet mature galaxies: Rare objects or is Big Bang model inaccurate?
Observation of two early yet mature galaxies: Rare objects or is Big Bang model inaccurate? (c) Copyright 2011 Louis Marmet The European Southern Observatory (ESO) recently reported a surprise while observing two extremely distant galaxies; at a very high redshift … Continue reading

Can Dark Money Theory Explain World Economic Crisis? (spoof)
Here’s a fun article comparing the claims that 96% of the Universe (matter and energy) is missing according to Big Bang conjecture and that 96% of the world’s cash that is missing due to derivatives.

Faster than Light Concern – Detecting Only 1 Neutrino per Hour
Regarding the potentially Faster than light Neutrinos, it is vital to realize that only about one (1) Neutrino is detected by Italy’s OPERA every hour; that’s one Neutrino per hour. Compare that to how every square centimeter on Earth (facing … Continue reading

Inflation’s Problems explained well
Here’s a very clear article in (relatively) plain English explaining problems with the Cosmological Inflation conjecture by Sean Carroll in Discovery Magazine. While I disagree with the author’s conclusion that the final ingredients of a “settled” cosmology hypothesis will include … 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. The most expensive science experiment in history, the Large Hadron … Continue reading

Stars or Sand? Are there more Grains of Beach Sand or Stars in our Visible Universe?
This began as a simple question, but it has intrigued enough people that I decided to feature it as an article._____________ Carol: “I have heard people say that there are more stars in the universe than there are the grains … Continue reading

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

Inverse Femtobarns – Measuring Collider Effectiveness

Physical Cosmology Hypothesis Application Form

New Record for Directly Measuring Astronomical Distances beyond our Local Supercluster – 450 million light years – with only 9% uncertainty
The new record for the farthest object whose distance was directly measured is 450 million light years with an uncertainty of no more than 9 percent. Our Milky Way galaxy is only 100,000 light years across. 450 million light years … Continue reading
