Electron No Longer a Fundamental Particle ?
Amazing news: Researchers in Switzerland have separated an Electron into two smaller quasi-particles – a “Spinon” and an “Orbiton;” meaning they have physically separated the spin and the orbit properties of an Electron. Until now, standard physics generally accepted that … 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). “In 1983, the metre was redefined in the International System of Units (SI) as the distance travelled by light … 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 Cherenkov radiation. Why? That doesn’t make sense. And its never been observed so … 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

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.”
