The Dancing Wu Li Masters by Gary Zukav
2 hr 41 min audio summary by author - Gary Zukav has written "the Bible" for those who are curious about the mind-expanding discoveries of advanced physics, but who have no scientific background. Like a Wu Li Master who would teach us wonder for the falling petal before speaking of gravity, Zukav writes in beautifully clear language--with no mathematical equations--opening our minds to the exciting new theories that are beginning to embrace the ultimate nature of our universe...Quantum mechanics, relativity, and beyond to the Einstein-Podolsky-Rosen effect and Bell's theorem. "Reality is what we take to be true. What we take to be true is what we believe. What we believe is based upon our perceptions. What we perceive depends upon what we look for. What we look for depends upon what we think. What we think depends upon what we perceive. What we perceive determines what we believe. What we believe determines what we take to be true. what we take to be true is our reality." EVERYTHING IS CONNECTED :)

Rare annular solar eclipse (longest of the millennium)
It was a once-in-a-millennium event on Friday when an annular solar eclipse plunged parts of Asia and Africa into partial darkness. The record-breaking eclipse, lasting 11 minutes, 8 seconds, will be the longest annular one until December 23, 3043, Reuters reported. According to astronomers, the best place to see the eclipse was in the Maldives, where it lasted the longest. An annular eclipse is when the moon passes in front of the sun, but does not completely block it, leaving a glaring ring of light.

Hubble's Successor: The James Webb Space Telescope
In this fourth episode of the Science@ESA vodcast series Rebecca Barnes will identify some of the key discoveries achieved with the famous Hubble Space Telescope, look at the concept of redshift, and meet a new telescope that will be used to uncover the early Universe.

The Fermi Gamma-ray Space Telescope, formerly GLAST, will open this high-energy world to exploration and help us to answer these questions. With Fermi, astronomers will at long last have a superior tool to study how black holes, notorious for pulling matter in, can accelerate jets of gas outward at fantastic speeds. Physicists will be able to study subatomic particles at energies far greater than those seen in ground-based particle accelerators. And cosmologists will gain valuable information about the birth and early evolution of the Universe.

before space there was no space - so the big bang occurred no where but everywhere how can there be a time before the bang when there was no such thing as time before the bang? before time there was not any time- - so, no time before time!

Time is flying by on this busy, crowded planet as life changes and evolves from second to second. And yet the arc of human lifespan is getting longer: 65 years is the global average way up from just 20 in the Stone Age. Modern science, however, provides a humbling perspective. Our lives indeed the life span of the human species are just blips compared to the age of the universe, at 13.7 billion years and counting. It now seems that our entire universe is living on borrowed time. How long it can survive in any form depends on whether Stephen Hawking's theory checks out.

that which consists of either matter or energy. Therefore if a god exists, it must be composed of either matter or energy. The opposite must also be true. If a god is not composed of matter or energy, then that god, by definition, does not exist. Thus to argue that a god exist, despite a total absence of matter or energy, is to argue, existence equals non-existence, which is a complete contradiction. If a god exists, then physical evidence is really the only methodology by which we can ascertain that a god exists. Of course, this does not require direct physical evidence -- we cannot perceive black holes directly, but we know that they exist due to the effects of their gravity wells on surrounding matter, as well as the flashes of energy that are released as captured matter crosses the event horizon. But since "existence" is defined as that which is composed of matter or energy, the proof of existence must be some evidence of that matter or energy. Evidence is defined as that which impacts our physical senses in some manner, either directly, or through some translating device such as a spectrograph or an oscilloscope. Since our sensory organs are designed to perceive the effects of matter and energy, it is through the evidence of the senses that we can determine the existence or nonexistence of things. If I argue that something exists, but then claim there is no way to detect it, my argument contradicts itself. Let's say I tell a deaf man that I hear a deep, loud sound coming from a speaker. If he lays his hand on it and feels no vibrations, he has every right to be skeptical. If I say that this loud sound does not have vibrations, he may then pull out his trusty microphone or other sound wave detector. If this instrument detects no sound in the vicinity, can I still tell him that this loud sound is occurring? At some point, if my definition of "loud sound" basically boils down to "that which is the opposite of any evidence that a loud sound is occurring," then clearly my approach to truth needs a little work. This approach helps clarify the truth value of the proposition that a god does not exist. If a god exists, then sensual evidence of some sort is required to determine the existence of that god. If a god is not made up of matter or energy, then that god does not exist, since that which is not composed of matter or energy -- does not exist. If a god is made up of matter and energy, then it is subject to physical laws. Since it is bound by physical laws, miracles are impossible, because miracles are, by definition, violations of physical laws. Likewise, a god cannot be all knowing and all-powerful, since both attributes would violate the basic tenets of physical laws. All knowing would require instantaneous knowledge of all matter, past, present and future, which is clearly impossible, while all powerful would require the ability to break the bounds of physical laws, which brings us back to the realm of nonexistence. If a god is subject to physical laws, then praying to a god makes about as much sense as worshiping a black hole, begging the Sun to grant you favors, or circumcising your son to appease the moon. If a god is not subject to physical laws, then the concept of a god is synonymous with the concept of non-existence. Why is there such resistance to the fact that a god does not exist? Many people redefine "God" within their own minds as "a potential form of matter or energy that has not been discovered yet," or "that which could exist in an alternate universe," or something to that effect. However, either a criterion for determining truth exists, or it does not. If such a criterion exists, then it must be objective, and based on the evidence of the senses and reason, which precludes the existence of any deities. If no such criterion exists, then both everything and nothing is true, and agnosticism, atheism, superstition, religion and the belief of the flying spaghetti monster are all equally valid. If an objective criterion for truth exists, then it cannot logically be applied according to whim, or only in situations that feel emotionally comfortable. Through this logical method we can determine no god exists. Actions are more important than beliefs.
