Related: UniverseTeleportation Teleportation is the name given by science fiction writers to the feat of making an object or person disintegrate in one place while a perfect replica appears somewhere else. How this is accomplished is usually not explained in detail, but the general idea seems to be that the original object is scanned in such a way as to extract all the information from it, then this information is transmitted to the receiving location and used to construct the replica, not necessarily from the actual material of the original, but perhaps from atoms of the same kinds, arranged in exactly the same pattern as the original. A teleportation machine would be like a fax machine, except that it would work on 3-dimensional objects as well as documents, it would produce an exact copy rather than an approximate facsimile, and it would destroy the original in the process of scanning it. In 1993 an international group of six scientists, including IBM Fellow Charles H. C.H.
The History of Pretty Much Everything : Starts With A Bang “Listen; there’s a hell of a good universe next door: let’s go.” -e. e. cummings Sometimes, you just need to take stock of what we know, and appreciate how far we’ve come. Will Betelgeuse really become a second sun in 2012? Several online news sites, including the Huffington Post, have reported that the star Betelgeuse will undergo a supernova explosion next year — yes, that's 2012 — and shine as brightly in the sky as a second sun. But according to scientists, it's all nonsense. "Betelgeuse is losing mass, and it will turn into a supernova soon, but that 'soon' means on an astronomical time scale: It's as likely to happen a million years from now as it is tomorrow," University of Illinois astronomer Jim Kaler told Life's Little Mysteries, a sister site of SPACE.com. No one knows quite when Betelgeuse, which is about 10 to 20 times more massive than our sun, will explode. But when it does detonate, the star, which forms the constellation Orion's right shoulder, won't look like a second sun in our sky, Kaler said. "The supernova would hit somewhere around the brightness of a crescent moon," said Kaler, who has focused his research on dying stars since the 1950s.
Birth of the Moon Posted by admin on Saturday, February 11, 2012 · The latest episode of Cosmic Journeys, enjoy in full HD 1080p. Scientists have been reconstructing the history of the moon by scouring its surface, mapping its mountains and craters, and probing its interior. What are they learning about our own planet’s beginnings? Decades ago, we sent astronauts to the moon as a symbol of confidence in the face of the great cold war struggle.

How the Sun Shines by John N. Bahcall* What makes the sun shine? Through The Wormhole: Are There Parallel Universes? Since the ancient Greeks first speculated that everything they observed in reality was the result of the interaction of tiny particles they called atoms, great thinkers have tried to find a single mathematical formula that governs and explains the workings of the entire universe. So far, though, even minds as brilliant as physicists Albert Einstein and Stephen Hawking have been unable to come up with that single grand equation of everything, also known as the theory of everything, or the final theory. Nevertheless, they continue to try, because without that final piece of the puzzle that is reality, the sum total of what we know falls a bit short of making sense. Perhaps the most illustrious searcher for the equation of everything was physicist Albert Einstein, who spent the last 35 years of his life trying to uncover such an overarching explanation.

Exoplanets An interactive version of XKCD 1071: Exoplanets using data from Planetary Habilitability Laboratory (via @ProfAbelMendez) and adapted code from the d3.js Bubble Chart example (by @mbostock). Planets are drawn to scale using radius data. The dataset also includes attributes such as atmosphere type, which is included in the information area on the left. The dataset is large (about 1.1mb), so it may take a few seconds to load. All blue and light brown planets are smaller than Jupiter. Space Zen: Will Humans' Brains Change During Travel in Outer Space? -A Galaxy Insight In February, 1971, Apollo 14 astronaut Edgar Mitchell experienced the little understood phenomenon sometimes called the “Overview Effect”. He describes being completely engulfed by a profound sense of universal connectedness. Without warning, he says, a feeing of bliss, timelessness, and connectedness began to overwhelm him. He describes becoming instantly and profoundly aware that each of his constituent atoms were connected to the fragile planet he saw in the window and to every other atom in the Universe. He described experiencing an intense awareness that Earth, with its humans, other animal species, and systems were all one synergistic whole. He says the feeling that rushed over him was a sense of interconnected euphoria.

Two Good Ways to Really *Get* the Solar System The Sun is one busy celestial body. In addition to giving us light, holding the solar system together, and providing the energy for almost every living thing on Earth, it’s also a grapefruit in a grass field in Austin, Texas, and a 50-foot yellow archway in northern Maine. Now, obviously this huge mass of incandescent gas is not literally making a tour of some of the geographical extremes of the contiguous U.S. states.
Greek Mythology Resource Page Greek Mythology Resource Page Greek mythology refers to the entire corpus of fantastic and heroic stories used by ancient Greek people to make sense of the world in which they lived. Though they are studied now mainly from a literary and cultural perspective, for the people of the classical Greek world, they were the facts of religious life. Greek mythology was intricately bound up in notions of cosmology , the study of the origin and nature of the universe. Natural phenomena in the observable world were attributed to gods from the earliest times; this helped Greek people understand and cope with the natural world.
