“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.”
