Ancient Hebrew Cosmology

clipper's remarks: Ancient Hebrew cosmology as illustrated by Michæl.Paukner:

The preceding description of the world doesn't share the same scientific view that we have, in which the Earth is one planet around one sun in a universe full of suns and planets. The ancient picture of the universe portrays a world in which the Earth is a disc surrounded by water not only on the sides, but underneath and above as well. A firm bowl (the firmament) keeps the upper waters back but has gates to let the rain and snow through. The Sun, Moon, and stars move in fixed tracks along the underside of this bowl. From below the disc, the waters break through as wells, rivers and the ocean, but the Earth stands firm on pillars sunk into the waters like the pillings of a pier. Deep below the Earth is Sheol, the abode of the dead, which can be entered only through the grave.

As portrayed in the illustration, the biblical cosmos consisted of three basic regions: the heavens, the land, and the underworld. In conclusion

Einstein's many contributions to physics include his special theory of relativity, which reconciled mechanics with electromagnetism, and his general theory of relativity, which extended the principle of relativity to non-uniform motion, creating a new theory of gravitation. His other contributions include relativistic cosmology, capillary action, critical opalescence, classical problems of statistical mechanics and their application to quantum theory, an explanation of the Brownian movement of molecules, atomic transition probabilities, the quantum theory of a monatomic gas, thermal properties of light with low radiation density (which laid the foundation for the photon theory), a theory of radiation including stimulated emission, the conception of a unified field theory, and the geometrization of physics.

The Stats Are In: No Global Cooling

Yet, as we see in the news there are those who want alternatives to Darwinian theory (solidly established in its basic form) as well as cosmology. Global warming does not impact the theology of a deity, but it does impact the theology of the dollar. So there is a lot of investment in creating noise and confusion on the matter. This is not too different from the tobacco industry's "Tobacco Institute," meant to make counter claims against cancer links and to generate noise and a smoke screen to protect profits from the industry. We have been seeing similar trends, with the Heartland Institute and others.

Stephen Hawking steps down as Lucasian professor at Cambridge

Wed Sep 30, 12:41 PM

LONDON - Physicist Stephen Hawking stepped down Wednesday as Lucasian Professor of Mathematics at Cambridge University after 30 years in the post.

The roughly 350-year-old position has been held by such luminaries as Isaac Newton and Charles Babbage, one of the fathers of modern computing. It is customary for professors to retire from the post the year they turn 67.

Hawking, who reached that age in January, will continue to work at the university as director of research at a department dealing with applied mathematics and theoretical physics.

"This is an exciting time in cosmology with new observational results coming in thick and fast and large-scale terrestrial and satellite experiments underway," Hawking said in a statement. "I want to make sure this progress is matched by the development of theories of the universe which are both mathematically consistent and observationally testable."

Olber's Paradox

In astrophysics and physical cosmology, Olbers' paradox, is the argument that the darkness of the night sky conflicts with the assumption of an infinite and eternal static universe. It is one of the pieces of evidence for a non-static universe such as the current Big Bang model. The argument is also referred to as the "dark night sky paradox" The paradox states that at any angle from the earth the sight line will end at the surface of a star. To understand this we compare it to standing in a forest of white trees. If at any point the vision of the observer ended at the surface of a tree, wouldnt the observer only see white? This contradicts the darkness of the night sky and leads many to wonder why we do not see only light from stars in the night sky.(see physical paradox).

Redshift

clipper's remarks: This could change your notion that the redshift of stars equals velocity. In fact, it challenges the notion of the Big Band theory itself! The redder the object, the younger it is.

Halton Arp

Because of Arp's photos, the assumption that high red shift objects have to be very far away - on which the "Big Bang" theory and all of "accepted cosmology" is based - is proven to be wrong! The Big Bang theory is therefore falsified.

The final irrefutable falsification of the "Redshift equals distance" assumption is the following image of galaxy NGC 7319 (Redshift = 0.0225). The small object indicated by the arrow is a quasar (Redshift z = 2.11) This observation of a quasar

In fact, a higher magnification image of the quasar (below) shows a "jet" of matter extending out from the center of NGC 7319 toward the quasar.

So, Arp is correct in his contention that redshift is caused mainly by an object's being young, and only secondarily because of its velocity. Therefore, quasars are not the brightest, most distant and rapidly moving things in the observed universe - but they are among the youngest.

A new cosmology

clipper's remarks: The Electric Universe states that the Big Bang never happened, that the universe is predominately electric in nature and that black holes, dark matter and pixie dust aren't real.

Clip Source: www.holoscience.com

Unlike big bang cosmology, plasma cosmology is subject to experimental tests in the laboratory and follows the Lichtenberg experimental tradition. Any 'bangs' it creates are real and noisy. Plasma cosmology can demonstrate with simple physical principles the electrical formation and behavior of spiral galaxies and stars without recourse to hypothetical dark matter and black holes.

The plasma cosmologist Eric Lerner, author of The Big Bang never Happened, says:

... one of the most destructive features of the methodology of the big bang is that it conveys the idea that only people versed in extremely complicated mathematics can understand the universe… This is, of course, the argument of the emperor's new clothes. If you can't see the emperor's new clothes you must be either stupid or incompetent.

Engineers are neither stupid nor incompetent.

And it is engineers who tend to prefer the real-world simplicity of the Electric Universe to the metaphysics of the big bang and black holes.

A theory of dark matter

Dark matter is unseen matter -- unseen in the sense that it emits no detected electromagnetic radiation (light, radio waves, etc) -- but it has been definitively spotted nonetheless because its gravity has measurable effects on stars, things that we can see.

CfA scientist Douglas Finkbeiner, together with three of his colleagues, has published a new paper

There are only four known forces in the world: the familiar gravitational and electromagnetic forces

the so-called strong and weak forces

So far as we know, these are the only forces there are, and scientists have generally supposed that these four will ultimately explain the dark sector as well

In working out their self-consistent theory of dark matter, the scientists find that a new, fifth force of nature is implied.

they argue that it is in fact a relatively straightforward solution

appears to solve a number of independent problem

subsequent research can now either contradict ... or confirm

inverse gambler's fallacy

Tue, 08 Sep 2009 13:31:49 GMT

clipped by: skwirlinator

Clip Source: en.wikipedia.org

The inverse gambler's fallacy is a term coined by philosopher Ian Hacking to refer to a formal fallacy of Bayesian inference which is similar to the better known gambler's fallacy. It is the fallacy of concluding, on the basis of an unlikely outcome of a random process, that the process is likely to have occurred many times before. For example, if one observes a pair of fair dice being rolled and turning up double sixes, it is wrong to suppose that this lends any support to the hypothesis that the dice have been rolled before. We can see this from the Bayesian update rule: letting U denote the unlikely outcome of the random process and M the proposition that the process has occurred before, we have

and since P(U|M) = P(U) (the outcome of the process is unaffected by previous occurrences), it follows that P(M|U) = P(M); that is, our confidence in M should be unchanged when we learn U.

No Inverse Gambler's Fallacy in Cosmology.

anthropic principle

Tue, 08 Sep 2009 13:21:50 GMT

clipped by: skwirlinator

Clip Source: en.wikipedia.org

In physics and cosmology, the anthropic principle is the collective name for several ways of asserting that physical and chemical theories, especially astrophysics and cosmology, need to take into account that there is life on Earth, and that one form of that life, Homo sapiens, has attained rationality. The only kind of universe humans can occupy is one that is similar to the current one.

The anthropic principle has given rise to some confusion and controversy, partly because the phrase has been applied to several distinct ideas. All versions of the principle have been accused of undermining the search for a deeper physical understanding of the universe. Those who invoke the anthropic principle often invoke multiple universes or an intelligent designer, both controversial and criticised for being untestable and therefore outside the purview of accepted science.

Suicidal planet seems on death spiral into star

Suicidal planet seems on death spiral into star

The odd, fiery planet is so close to its star and so large that it is triggering tremendous plasma tides on the star. Those powerful tides are in turn warping the planet's zippy less-than-a-day orbit around its star.

The result: an ever-closer tango of death, with the planet eventually spiraling into the star.

The star is called WASP-18 and the planet is WASP-18b because of the Wide Angle Search for Planets team that found them.

The planet is 1.9 million miles from its star, 1/50th of the distance between Earth and the sun, our star. And because of that the temperature is about 3,800 degrees.

Its size - 10 times bigger than Jupiter - and its proximity to its star make it likely to die, Hellier said.

WASP group: http://www.superwasp.org/

Nature: http://www.nature.com/nature

The answer will become apparent in less than a decade if the planet seems to be further in a death spiral, he said.

Atheist Turns To God

clipper's remarks: g05 12/8 p. 28 Watching the World

Clip Source: jwitness-nonofficialwebsiteblogger.blogspot.com

A British philosophy professor who has been called “the world’s most influential atheist” now says that he believes in God. In an online preview of an interview scheduled to be published in the journal Philosophia Christi, 81-year-old Dr. Antony Flew said that he “had to go where the evidence leads.” According to Flew, this evidence includes recent scientific discoveries in the fields of cosmology and physics. Additionally, “the findings of more than fifty years of DNA research have provided materials for a new and enormously powerful argument to design,” he explained. Even the “biblical account [of Genesis chapter one] might be scientifically accurate,” he states. So, is he ready to become a practicing Christian? “It’s very unlikely,” he says. However, “if I wanted any sort of future life I should become a Jehovah’s Witness.”

it has been said that the observable universe is many orders of magnitude smaller than the greater universe that lies beyond the limits of our perception.

Imagine that the entire cosmological horizon is modeled by a sphere that is the diameter of a quarter (24.26 mm in diameter). If Alan Guth's inflationary model of early era cosmology is correct, the universe that lies beyond this “quarter-sized” horizon would conservatively be a sphere as large as the Earth globe itself.

Many of the great physicists have said that "time is an illusion". In the same sense, does that mean the big bang is an illusion?

Chaos

Later on Chaos was described as an original state of existence from which the first gods appeared. In other words, the dark void of space.

In Greek it is Χάος, which in ancient Greek was pronounced [ˈkʰa.os]. It means "gaping void", from the verb χαίνω "gape, be wide open, etc", Proto-Indo-European *"ghen-", *"ghn-"; compare English "chasm" and "yawn", Old English geanian = "to gape".

In Ancient Greek cosmology, Chaos was the first couple of things to exist and the womb from which everything emerged. For Hesiod and the Olympian mythos, Chaos was the 'vast and dark' void from which the possible first deity, Gaia, emerged. In the Pelasgian creation myth, Eurynome ('goddess of everything') emerged from this Chaos and created the Cosmos from it^{[citation needed]}. For Orphics, it was called the 'Womb of Darkness' from which the Cosmic Egg that contained the Universe emerged. It is sometimes conflated with 'Black Winged Night'.

clipper's remarks: End of Cosmology – 3 trillion years from now.

End of Stars – 100 trillion years from now.

The End of Regular Matter – 10 to the power of 30 years from now.

End of Black Holes – 10 to the power of 100 years from now.

The End of Everything – 10 to the power of 100 years and beyond.

Perhaps there will be another Big Bang someday. Perhaps the Universe is cyclical and the whole process will start up again.

Perhaps it won't, and this bleak future of a cold, dead Universe is all that awaits us. It's not happy, but it's awe inspiring to consider the long future ahead, and helps us appreciate the vibrant age we live in today.

The End of Everything

Let's really think big, stare forward in time, and think about what the future holds for the Universe. Look forward millions, trillions, and even 10¹⁰⁰ years into the future. Let's consider the end of everything.

End of Humanity

The vast majority of every species that has ever lived on Earth is now extinct. To think that humans can avoid the fate of every other creature is arrogant. Like all life on Earth, our time is limited. How long will we last?

There's no way to know, but there's a calculation that can help. It's called the Doomsday Argument

10,000 years

there's a 95% chance that humanity will have ended by the year 11,000.

End of Life – 500 million years – 5 billion years

That's because the Sun is slowly heating up.

Over the course of the next few billion years, evolution will seem to go reverse. The largest organisms and least heat tolerant animals will die out, leaving hardy insects and bacteria.

End of the Earth – 7.5 billion years

End of the Sun – 7.5 billion
