POPSThe life of Albert Einstein - He is best known for his theory of relativity and specifically mass-energy equivalence, E = mc2. Einstein received the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect."

POPSA new cosmology 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.

POPSThe End of Everything 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.

POPSMarcelo Gleiser on How do We Know? Marcelo Gleiser, Appleton Professor of Natural Philosophy at Dartmouth College, is a theoretical physicist who has worked on a diverse set of topics: cosmology, particle physics, phase transitions, condensed matter physics and biophysics. an interesting take on the concept of reality and existence, notice the last statement: "In this case, and in a paradoxical way, the theories that we construct to amplify our view of physical reality will actually limit what we can know about nature."

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.

POPSDyson, Freeman John There's an aspect of things which I find amusing: the flow back and forth between science and science fiction, which has been an important part of my life. I started out reading science fiction and then became a scientist, and that set the slant on my scientific work. I like to make connections between life and cosmology and astronomy. Science fiction raises all these interesting possibilities and has had some influence on science in the last 25 years – not only in the area of SETI, but also in other ways. 1. Dyson, F. J.

POPSArtifacts and Human History Yet many other unearthed "out-of-place artifacts" create obvious contradictions to the conservative picture of antiquity. They don't fit the established pattern of prehistory, pointing back instead to the existence of advanced civilizations before any of the known ancient cultures came into being.

POPSDark Energy’s Effects Clearly Seen For The First Time
The X-ray results combined with supernovas information has given astronomers the best data so far about dark energy properties and it clearly shows that dark energy exists and it’s a cosmological constant. However, this raises another debate as scientists believe now that hidden dimensions really exist. “Putting all of this data together gives us the strongest evidence yet that dark energy is the cosmological constant, or in other words, that ‘nothing weighs something’. A lot more testing is needed, but so far Einstein’s theory is looking as good as ever,” added Vikhlinin. Ultimately, the astronomers predicted the destiny of the Universe that will continue to accelerate and expand which means that the Milky Way and the Andromeda galaxies will never merge with the Virgo galaxy clusters. In conclusion, the astronomers believe that about 100 billion years from now, we will not be able to see other galaxies from the Milky Way, and many other galaxy clusters will eventually decompose.

POPSOn The Way To An Electrical Universe? Electrical effects and currents can be measured in the physical universe. Hence the character of the universe is electrical in nature period. If they look at the effects they'll see the electric nature of the cosmos.

POPSDark flow, when the universe as you know is closing on you
"If confirmed, this will be an exciting way of probing the ultimate structure of the universe and perhaps even the multiverse," Kashlinsky says. "But you have to check and recheck." "If this thing is confirmed and it is real, it will be incredibly important," says Aguirre, "on the same order of discovery as the realisation that those little smudges on the sky are other galaxies. The most important thing it would tell us is that the standard picture is broken in some way. And the most exciting thing it could tell us is that there are other universes." If it does, space and time will open up to reveal a reality that is so much bigger than we know. When that happens, those claustrophobia-stricken cosmologists will finally be able to breathe easy." What i find as most interesting is the passion to go beyond the obvious barriers. As i read once in a book series i love, the golden age, even in the size of the universe, a jail is still a jail...

POPSMystery roar detected from far, far, away continues: There is "something new and interesting going on in the universe," said Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md. A team led by Kogut detected the signal with a balloon-borne instrument named ARCADE (Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission). In July 2006, the instrument was launched from NASA's Columbia Scientific Balloon Facility in Palestine, Texas, and reached an altitude of about 120,000 feet (36,500 meters), where the atmosphere thins into the vacuum of space. ARCADE's mission was to search the sky for faint signs of heat from the first generation of stars, but instead they heard a roar from the distant reaches of the universe. "The universe really threw us a curve," Kogut said. "Instead of the faint signal we hoped to find, here was this booming noise six times louder than anyone had predicted."

POPSEarth is not the center of the universe The Copernican Principle, had a significant impact upon human perception, the self importance stemming from religious beliefs, was changed. it gave away for a more curious and ambitious perception.
