POPSScience breakthrough There is no current reasoning over why matter prevailed over antimatter, but many believe it was the result of asymmetry, and some scientists believe that the ratio of this asymmetry was roughly a billion antimatter particles to a billion and one matter particles

POPSRocket Scientists Say We'll Never Reach the Stars Even the most theoretically efficient type of propulsion, an imaginary engine powered by antimatter, would still require decades to reach Alpha Centauri, according to Robert Frisbee, group leader in the Advanced Propulsion Technology Group within NASA's Jet Propulsion Laboratory. And then there's the issue of fuel. It would take at least the current energy output of the entire world to send a probe to the nearest star

POPSIs The "Scientific Consensus" On Global Warming A Myth?
Their work is cited and acclaimed throughout the scientific community. No wonder Gore and his allies want to pretend they don't exist. This is the one book that PROVES the science is NOT settled. The scientists profiled are too eminent and their research too devastating to allow simplistic views of global warming--like Al Gore's--to survive. Al Gore says any scientist who disagrees with him on Global Warming is a kook, or a crook. Guess he never met these guys Dr. Edward Wegman demolishes the famous "hockey stick" graph that launched the global warming panic Prof. Hendrik Tennekes states "there exists no sound theoretical framework for climate predictability studies" used for global warming forecasts. Dr. Antonino Zichichi who discovered nuclear antimatter--calls global warming models "incoherent and invalid." Dr. Syun-Ichi Akasofu twice named one of the "1,000 Most Cited Scientists," says much "Arctic warming during the last half of the last century is due to natu

POPSHow Anti-Matter Propulsion Works It's not rocket science...at least rockets as we know them. :) So, why haven't we built a matter-antimatter reaction engine? The problem with developing antimatter propulsion is that there is a lack of antimatter existing in the universe. For now, we will have to create our own antimatter. Luckily, there is technology available to create antimatter through the use of high-energy particle colliders, also called "atom smashers." But these high-energy particle accelerators only produce one or two picograms of antiprotons each year. A picogram is a trillionth of a gram. It states that anti-matter propulsion is the most energy efficient propulsion. I suspect that will be true as long as the process of making the anti-matter is itself efficient enough to make it feasible.

POPSNew twist to matter-antimatter mystery Here is an "almost breakthrough" A major mystery of modern physics is why normal matter particles are the building blocks of the observable universe. Why are we not made of antimatter? Or pure energy? Scientists speculate that a tiny imbalance in the early universe allowed a small fraction of normal matter – one particle for every one billion – to avoid annihilation and survive to form stars, planets, and humans. When we come to know that we don't know, there is a new place for hope...

POPSThe ABCs of nuclear science - Interesting link * Do you want to know about the modern concept of the nucleus? * How nuclear physicists view the nucleus? * How could anyone measure something that small? * Do you know how we find new elements? * What are accelerators used for? * What is radioactivity and is it dangerous? * What do nuclear physicists really do?

POPSWeird dark stars dotted early universe Quasars usually need the mass of a galaxy to form, and astronomers have been unable to explain how some quasars seemed to appear before galaxies had formed to make them. These 'dark stars' provide a means by which this may have happened.

POPSGod Is the Machine---0 then 1 There are many ways to view God & any sober member of AA realizes that some concept of God/Power greater than themselves is necessary to their recovery & part of the 12 Steps. 2. Came to believe that a Power greater than ourselves could restore us to sanity. 3. Made a decision to turn our will and our lives over to the care of God as we understood Him. 5. Admitted to God, to ourselves and to another human being the exact nature of our wrongs. 6. Were entirely ready to have God remove all these defects of character. 11. Sought through prayer and meditation to improve our conscious contact with God as we understood Him, praying only for knowledge of His will for us and the power to carry that out. 12. Having had a spiritual awakening as the result of these steps, we tried to carry this message to alcoholics and to practice these principles in all our affairs.

POPSMust-know terms for the 21st Century intellectual One author's mostly optimistic prediction of the ideas that will come to define our collective future. Nicely done. Open Source : This is a term that most people are familiar with, but it’s worth re-stating. The open source revolution, where information is freely distributed and editable, is already reshaping a number of industries and upsetting traditional economic and intellectual property models. Wikipedia has very quickly become the world’s largest repository of encyclopedic information. Linux and other open source software continue to rival the big players. And looking further down the line, there’s the potential for open source science, culture, and the disturbing potential for open source warfare.
