Dark Matter — You’re Out !

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 essentially completed search for Higgs Bosons. (Update: See “Did CERN Find a Higgs ? Well not quite. But they probably found a New Particle ! and extended their funding for years“) Well, now the hypothesis called “Dark Matter” is facing a similar fate. What a contrast with a mere five years ago when both Dark Matter and Higgs Bosons were expected to be found rapidly. Continue reading →

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 an Electron was a fundamental particle – that it was not made of smaller components.

However, as early as 1980 theorists had predicted an electron could be made of three smaller pieces: A “Spinon” (providing spin), an “Orbiton” (providing the orbit) and a “Holon” (carrying the charge).

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 to learn everything that goes into making the celestial beautiful.

Well, here’s an interview with an Astronomical Image Enhancement engineer, Brant Widgeon, who describes one of the lesser known phenomena that interferes with so many space photographs.

“Perfect” Light Speed available with miniscule adjustment to the Second or the Meter Definition

Posted on January 30, 2012 by David

LightSpeed HyperSpace
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 in vacuum in 1⁄299,792,458 of a second.“

Because the speed of light (known as “c” to mathematicians and physicists) does not exactly match 300,000 kilometers per second, it makes calculations for physicists and mathematicians unnecessarily tedious.

Must Faster-than Light Neutrinos Cause Cerenkov Radiation?

Posted on November 22, 2011 by David

Cherenkov Radiation Credit: Wikipedia

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 how would anyone test that?

Cherenkov Radiation Requires Charged Particles – But Neutrinos Have No Charge

The beautiful blue-violet glow of Cherenkov Radiation is only caused by charged particles, primarily electrons.

Observation of two early yet mature galaxies:

Rare objects or is Big Bang model inaccurate?

News Flash: (June 12, 2012) This article was just nominated as one of the best science blog articles of the past year at 3-Quarks Daily. In voting it just missed getting in the top 20 of the 107 articles nominated; proving more popular than several Scientific American articles.

The European Southern Observatory (ESO) recently reported a surprise while observing two extremely distant galaxies; at a very high redshift (z = 3.57); so far away that they are seen as they were a long time ago: only 1.8 billion years after Big Bang.

The surprise was to discover that the cool gas in these presumably young galaxies was very rich in heavy elements (all called metals), a chemical composition usually only seen in older galaxies because it takes so long to make heavy elements.

ESO reports that an international team used the flash of a distant gamma-ray burst GRB 090323 as a probe to study the spectra of the two galaxies (G0 and G1). The bright light emitted by the burst was absorbed by the gas in both galaxies. The measured absorption spectrum allowed an evaluation of the density of heavy elements. Continue reading →

Not Sure about Uncertainty ;-)

I’m Not Sure about the Uncertainty Principle

Apple Bitten: courtesy Wikimedia

It is difficult to test the flavor of an apple without biting it or taking some sample out of it. You or I can test or measure its flavor by taking a bite of it or taking a small piece for examination. Either method of testing changes the apple irreversibly. Testing which harms or changes the tested phenomena or materials is called “Destructive Testing.”

When I take a photograph inside a building, where the light is dimmer, I usually use a flash.

Using a flash intentionally affects the subject of the photograph in a demonstrable way (a flash changes how someone looks in a photograph), and also in an unintended way — some people react to a strong flash of light in their eyes.

By contrast – photography without a flash does not affect the “model,” at least not with light.

Similarly, while X-rays show us the inner workings of some things, they also harm living photography subjects by damaging the DNA of living tissue.

Faster than Light Concern – Detecting Only 1 Neutrino per Hour

Posted on October 25, 2011 by David

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 the Sun) encounters some 65 billion solar neutrinos per second.

Neutrino Beam Path

When that single neutrino hits in Italy, its timed arrival is associated (extrapolated back) to a recorded proton pulse at CERN by using the time it would take for a photon to travel the same distance.

Stars or Sand? Are there more Grains of Beach Sand or Stars in our Visible Universe?

Posted on October 10, 2011 by David

This began as a simple question, but it has intrigued enough people that I decided to feature it as an article and expand it so we can have some fun.

_____________
Carol Charming:

“I have heard people say that there are more stars in the universe than there are the grains of sand ‘on the beach.’

What size is the beach and are the grains of sand coarse or fine? Or does the saying go “all the grains of sand on all the world’s beaches,” something I simply can’t believe to be true.”

Carmel (Charmel) Beach has many more grains of sand than our Milky Way has Stars

Carmel (Charmel) Beach has many more grains of sand than our Milky Way has Stars

Disclaimer —
You and I will work through to get an answer, but be warned — There will never be a definitive, conclusive, absolute, precise or final answer to this question.

For either counting stars or sand grains — there simply is no measurement, or accurate calculation or mathematical proof or method of counting – nor will one ever conceivably exist.

Its even worse than that — we can’t even get approximate numbers for either with much confidence.

We can only roughly estimate the number of stars in our own galaxy. Estimates easily vary by 150 times (more than two orders of magnitude) and estimates of the number of grains of beach sand are even worse.

How Are Neutrino Flavors Different ? Maybe There Is Only Vanilla . . .

Posted on September 27, 2011 by David

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 Neutrinos have zero electric charge making them beyond invisible; nearly impossible to detect. They are only affected by the Weak force and Gravity; both effects are extremely difficult to detect at the atomic scale.

What makes Neutrinos unique among particles is that they seem to change structure or “flavor” (called oscillation) . . . in very short distances. (Kind of like the Transformer toys – except instead of changing shape, Neutrinos seem to change mass ! – both up and down – which of course violates the bedrock principle of conservation of mass-energy.)

While working on another problem, a team of physics researchers at CERN and the Gran Sasso Laboratory in central Italy found a potentially revolutionary result seven months three years ago.

They have spent the subsequent seven months three years quietly verifying – that muon Neutrino particles seem to be traveling faster than the speed of light, called Superluminal Motion.

(A very happy) Team spokesman Prof. Dr. Antonio Ereditato said “We have high confidence in our results. We have checked and rechecked for anything that could have distorted our measurements but we found nothing,” he said. “We now want colleagues to check them independently.” (Quote credit: Reuters reporter Robert Evans)

Higgs Boson – Imaginary Particle Remains Science Fiction – Big Bang Weakens Further

Brünnhilde Singing

Brünnhilde Singing

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 ends, it appears that a Higgs Boson is detected. See “Closing in on Higgs Boson Certainty, But “Standard Model Higgs” Remains Distant“.

The most expensive science experiment in history, the Large Hadron Collider, has failed to find the Higgs Boson which is required for Big Bang and Expanding Universe ideas (as well as its role as a key component of particle physics “Standard Model“).

HyperBaseline Telescopes – NanoArcSecond Resolution

Posted on July 1, 2011 by David

HyperBaseline Telescopes

Imagine resolving details of nearby stars and their planets.

Sub-nano-arc second resolution should be possible with this proposal for a telescope that is composed of a set of three sets of two (six total) lens-sensor spacecraft systems that send images and data back to Earth from three baselines that can begin sending ground breaking data when the spacecraft are separated by 10 times Earth’s diameter. The baselines of the six spacecraft grow over some 100 to 200 years to about 100 billion miles (roughly 1100 AU, 2 hundredths of a light year or 160 terameters).

Article on Big Bang’s Inadequate Definition Disputed – But Article Emerges Unscathed

Posted on June 10, 2011 by David

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 (I’ve made mistakes before and far prefer to get them corrected quickly), the critique fails to identify any flaws in my article and contains a number of incorrect or misleading assertions — including the false claim that the complete quote by Professor Peebles is somehow out of context.

It also spends most of its extensive effort with an elaborate distraction where it tries but falls short of describing a complete hypothesis for Big Bang. Since the article is copied on other blogs, its errors need correcting. So, here are some responses to the dispute article’s ideas and quotes.

Inverse Femtobarns – Measuring Collider Effectiveness

Posted on May 31, 2011 by David

Here’s a fun article on possible identification of a new particle.

FermiLab - Illinois

FermiLab - Illinois

Update (July 2011): Unfortunately, this exciting potential evaporated under more rigorous scrutiny. But, that’s exactly the way science is supposed to work. We are supposed to abandon even our most treasured concepts when data can not support it, and embrace data even when it contradicts our wishes about natural phenomena.

Update (June 2011): Rats – verification by a second team failed; it shows no similar “bump” meaning that hope for the alleged new particle is evaporating, but not disappeared. Nevertheless, the amusing term remains :-)

It describes how the evidence is getting stronger – and we may have a new particle confirmed soon.

New Record for Directly Measuring Astronomical Distances beyond our Local Supercluster – 450 million light years – with only 9% uncertainty

Posted on February 19, 2011 by David

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 is more than four thousand times the diameter of our galaxy. Our “local” Supercluster centered on Virgo is only 150 million light years across – one-third of the new distance measurement record.

This was set by the world’s largest telescope, the Very Large Baseline Array telescope (VLBA) which extends from Hawaii to New Hampshire, and boasts a resolution a hundred times sharper than the Hubble Space Telescope.
