POPSRussia May Send Spacecraft to Asteroid Tunguska's piece of comet that detonated over Siberia in the early 1900's was estimated to be only One hundred feet across. How is a spacecraft going to move this rock with an impact--sustained ion-pulse rocket engines?? They'll just make it hit earth on 2029....I had hoped to live longer than this..

POPSA Fascinating NDE "The Void is the vacuum or nothingness between all physical manifestations. The SPACE between atoms and their components. Modern science has begun to study this space between everything. They call it Zero point. Whenever they try to measure it, their instruments go off the scale, or to infinity, so to speak. They have no way, as of yet, to measure infinity accurately."

POPSThe Fluff Is Coming! The Fluff Is Coming! "There could be interesting times ahead!" says Opher." More from the article below: "The fact that the Fluff is strongly magnetized means that other clouds in the galactic neighborhood could be, too. Eventually, the solar system will run into some of them, and their strong magnetic fields could compress the heliosphere even more than it is compressed now. Additional compression could allow more cosmic rays to reach the inner solar system, possibly affecting terrestrial climate and the ability of astronauts to travel safely through space. On the other hand, astronauts wouldn't have to travel so far because interstellar space would be closer than ever. These events would play out on time scales of tens to hundreds of thousands of years, which is how long it takes for the solar system to move from one cloud to the next."

POPS"Our World May Be A Giant Hologram" continues (full at source): For many months, the GEO600 team-members had been scratching their heads over inexplicable noise that is plaguing their giant detector. Then, out of the blue, a researcher approached them with an explanation. In fact, he had even predicted the noise before he knew they were detecting it. According to Craig Hogan, a physicist at the Fermilab particle physics lab in Batavia, Illinois, GEO600 has stumbled upon the fundamental limit of space-time - the point where space-time stops behaving like the smooth continuum Einstein described and instead dissolves into "grains", just as a newspaper photograph dissolves into dots as you zoom in. "It looks like GEO600 is being buffeted by the microscopic quantum convulsions of space-time," says Hogan.

POPSThe Psychology of Cyberspace John Suler, Ph.D. Department of Psychology, Science and Technology Center Rider University. There is a rapidly growing field of 'cyberpsychology': the contents here suggest some of the areas of focus. Clearly, business and marketing research are well represented in studies; another interesting area of study is the social site as a virtual laboratory for studying human personality, motivation,etc; related to the latter the pressing question of how internet relationships (e.g. friendship, group, lover) interact with individuals' lives beyond the internet.

POPSGraphic: Timeline of the Big Bang An informative graphical timeline of the very creation of time, space, matter, and energy in our universe. Cool! I just clipped the first paragraph of the nicely written description that accompanies it. Of course, cosmology, cosmogony, and quantum physics, and the origins of space-time are some of the hardest fields of study being pursued right now. Any other pointers to clip-size explanations would be welcome additions to Clipmarks.

POPSPlaying tricks with the speed of light The mechanics of slowing light down, as well as speeding it up, is governed by methods and equations that are pretty well understood. Now scientists just have to figure out what to do with it.

POPSThe Big Picture of the Milky Way The image spans a mind-boggling area of 120 feet long (ca. 36.6 m) by 3 feet wide at its sides, bulging to 6 feet at the center of our humongous galaxy. The panorama represents the combined effort of two Spitzer survey teams, who used two of the onboard instruments.
