    A fireball that appeared over the Sri Lankan province of Polonnaruwa on December 29, 2012 was a meteorite containing algae fossils, according to a paper published in the Journal of Cosmology. A team of researchers, led by Jamie Wallis of Cardiff University, believes that these fossils provide evidence of cometary panspermia, the hypothesis that life originated in outer space and comets brought it to Earth. Scientists at the Sri Lankan Medical Research Institute in Colombo forwarded 628 stone fragments that allegedly fell from the fireball to Cardiff University, where Wallis' team indentified three as originating from a carbonaceous chondrite.

    Massive Quasar Cluster Refutes Core Cosmology Principle by Brian Thomas, M.S. * Astronomers recently found a distant collection of quasars. But those quasars shouldn’t exist. And while they certainly appear connected, they’re spread too far across space for standard secular models of the structure and origin of the universe to accommodate. “It is the largest structure ever seen in the entire universe,” according to astrophysicist Roger Clowes from the University of Central Lancashire.1 Clowes led a team of researchers, who published their discovery in The Monthly Notices of the Royal Astronomical Society,2 in analyzing data from the Sloan Digital Sky...

    A group of Penn State physicists says the universe we now see could have arisen from a "Big Bounce" rather than a Big Bang. The new work by Penn State, led by professor Abhay Ashtekar, director of the Institute for Gravitation and the Cosmos, proposes ways to apply quantum physics "further back in time than ever before – right back to the beginning," the university says in a release. We have a pretty good idea of the large-scale structures of the universe when it was only a few hundred thousand years old. That comes from studying the fingerprint of the...

    Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe. Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full moon. The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble Space Telescope data from 2003 and...

    University of Warwick astrophysicists have pinpointed four white dwarf stars surrounded by dust from shattered planetary bodies which once bore striking similarities to the composition of the Earth. The scientists publish their results in a paper in the journal Monthly Notices of the Royal Astronomical Society. White dwarfs are the final stage of life of stars like our Sun, the residual cores of material left behind after their available fuel for nuclear reactions has been exhausted. Using the Hubble Space Telescope to carry out the biggest survey to date of the chemical composition of the atmospheres of white dwarf stars,...

    Astronomers have discovered their "holy grail" - a planet capable of supporting life outside our solar system. The planet lies in what they describe as a 'habitable zone', neither too near its sun to dry out or too far away which freezes it. And the discovery could help answer the question of whether we are alone in the universe, which has been plagued astronomers and alien fanatics for years. Scientists found the planet, Gliese 667Cc, orbiting around a red dwarf star, 22 light years away from the earth. Red dwarf stars are the most common stars in the neighbourhood of...

    Einstein is still the boss, say researchers with the BOSS project for measuring key properties of the universe. BOSS, for Baryon Oscillation Spectroscopic Survey, has measured the distance to faraway galaxies more precisely than ever before, mapping the universe as it existed roughly 6 billion years ago, when it was only 63 percent of its current size. The findings suggest that the mysterious “dark energy” causing the universe to expand at an accelerating rate was foreseen by Einstein, the researchers reported April 1 at the American Physical Society meeting. To keep the universe in a static state, Einstein added a...

    Astronomers have measured the precise distance to over a quarter of a million galaxies to gain new insights into a key period in cosmic history. The 3D map of the sky allows scientists to probe the time six billion years ago when dark energy became the dominant influence on the Universe's expansion. No-one knows the true nature of this repulsive force, but the exquisite data in the international BOSS survey will help test various theories. The analysis appears in six papers. These have all been posted on the arXiv preprint server. "This is an incredibly exciting time to be working...

But a new study hints that the most common life in the universe might exist deep inside eternal-night worlds far from any star, adrift in the icy dark of interstellar space. Researchers at the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) at Stanford University estimate that "nomad" planets, ejected from their home stellar system and now free-floating through the Milky Way, could outnumber stars by as many as 100,000 to 1. Earlier estimates were more like a...

    NASA's Spitzer Space Telescope has detected the crossing of a solid planet in front of a star located at only 42 light-years in the constellation Cancer. Thanks to this detection, astronomers know that this "super-Earth" measures 2.1 times the size of our Earth. This is the smallest exoplanet detected in the neighborhood of our Sun. The discovery is based on data acquired by the Spitzer spacecraft last January. The data allowed astronomers to detect the "transit" of the planet, i.e. the tiny decrease of the star's brightness occurring when the planet passes in front of it. "So far, the exquisite...

    If the Universe expands and contracts in cycles of Big Bangs and Crunches, some black holes may survive from one era to the next, according to a new analysis Black holes are regions of space in which gravity is so strong that nothing can escape, not even light. Conventionally, black holes form during a gravitational collapse, after a large supernova for example. But there is another class of objects called primordial black holes that cosmologists think must have formed in a different way. These are essentially leftovers from the hugely dense ball of stuff from which the universe expanded, some...

    The latest experiment at CERN went ahead despite warnings by a group called Heavy Ion Alert that it could trigger a catastrophic chain reaction that might destroy the Earth. The reaction created temperatures a million times hotter than the centre of the Sun, which have not been reached since the first billionths of a second following the Big Bang. This was expected to cause atomic particles such as protons and neutrons to melt, producing a "soup" of matter in a state previously unseen on Earth. Scientists, including British particle physicists, will now study the particles in the hope of...

    Today physicists announced that they may have found the key to explaining dark matter in the universe. It all has to do with the potential discovery of a "sterile neutrino." According to a release about the new study: Neutrinos are neutral elementary particles born in the radioactive decay of other particles. The known "flavors" of neutrinos are the neutral counterparts of electrons and their heavier cousins, muons and taus. Regardless of a neutrino's original flavor, the particles constantly flip from one type to another in a phenomenon called "neutrino flavor oscillation." An electron neutrino might become a muon neutrino, and...

The main purpose of this book is to give a brief synopsis of this evidence to readers who...

Surveys of the cosmos are based on a signature of ultraviolet light that turns out to be a poor indicator of what's out there, its authors say. In the case of very distant, old galaxies, the telltale light may not reach Earth as it is blocked by interstellar clouds of dust and gas -- and, as a result, these galaxies are missed by...

    Was Newton right and Einstein wrong? It seems that unzipping the fabric of spacetime and harking back to 19th-century notions of time could lead to a theory of quantum gravity. Physicists have struggled to marry quantum mechanics with gravity for decades. In contrast, the other forces of nature have obediently fallen into line. For instance, the electromagnetic force can be described quantum-mechanically by the motion of photons. Try and work out the gravitational force between two objects in terms of a quantum graviton, however, and you quickly run into trouble—the answer to every calculation is infinity. But now Petr Hořava,...

This was satirized by Sidney Harris years ago in a cartoon that showed a grad student filling a blackboard with equations. His adviser called attention to one step that needed some elaboration: It said, "Then a miracle happens." Examples of miracles in evolutionary philosophy include the sudden appearance of the universe without cause or explanation, the origin of life, the origin...

    When the Fermi team did the calculations, using the most conservative estimates for how astrophysics plays into this, they determined that the mass scale must be at least 1.2 times the Planck mass, and by using reasonable but less conservative assumptions, they derived lower limits on the mass scale of up to 100 times the Planck mass. One way to interpret this is to say that there is no variation of the speed of light coming from any quantum gravity effects at less than 1.2 times the Planck mass. And given that some quantum gravity frameworks predict that effects should...

    Many people make a distinction between the origin of life and the evolution of life. In this view, biological evolution refers to the gradual development of the diversity of living things from a common ancestor, while the ultimate origin of life is a separate question. This is a legitimate point, but evolution is about much more than just biology. The evolutionary worldview is that all of physical existence, both living and non-living, arose through purely natural processes. With this broad definition of evolution, abiogenesis--the spontaneous appearance of life from non-living matter--is a necessity. If life did arise on earth by...

Women are evolving fatter:  New Scientist and PhysOrg said that natural selection is making women shorter, plumper and more fertile.  “The take-home message is that humans are currently evolving,” said Stephen Stearns of the National Evolutionary Synthesis Center in Durham, North Carolina.  “Natural selection is still operating.” Killer algae heading north:  Science Daily said that toxic algae was a key player in mass extinctions in the past, and...

    Oct 7, 2009 — Saturn has a newly-discovered ring to add to its decor – the largest of all. It’s so big, it makes Saturn look like a speck in the middle of it. The ring, located at the orbit of the small outer moon Phoebe, is inclined 27 degrees and revolves backwards around Saturn. This was announced today by...

    Outer Limits Not Lively Sept 29, 2009 — One of the “cosmic coincidences” cited in the intelligent-design treatise The Privileged Planet1 is the “galactic habitable zone” – a fairly narrow region of the galaxy where planets can form and exist safely.  The outer regions of the galaxy were described as lacking the heavy elements necessary for planet formation. Score one for the authors.  New Scientist reported on a planet search by astronomers at the University of Tokyo who failed to find planets in the outer reaches of the galaxy.  “Astronomers have long doubted that life could exist there,” the article...

    Scientists have peered further back in time than ever before using instruments designed to search for a phenomenon predicted by Albert Einstein almost a century ago but not yet proven to exist. An American observatory hunting for ripples in space and time called gravitational waves has produced its most significant results yet, despite not having directly detected any. Tycho's Supernova The “non-discovery” offers insights into the state of the Universe just 60 seconds into its existence. Previous research has been unable to look back in time further than about 380,000 years after the big bang. The new window on the...
  • Study Plunges Standard Theory Of Cosmology Into Crisis

    Science Daily ^ | 5/5/2009
    As modern cosmologists rely more and more on the ominous “dark matter” to explain otherwise inexplicable observations, much effort has gone into the detection of this mysterious substance in the last two decades, yet no direct proof could be found that it actually exists. Even if it does exist, dark matter would be unable to reconcile all the current discrepancies between actual measurements and predictions based on theoretical models. Hence the number of physicists questioning the existence of dark matter has been increasing for some time now. Competing theories of gravitation have already been developed which are independent of this...

    String theory “philosophy” challenged --snip-- The big bang is fundamental to cosmic evolution or the idea that somehow the universe made itself. The article majored on the varying ideas that emanate from big bang philosophy, such as dark energy and dark matter etc. that are used to solve some of the “science” problems of the big bang. It then went on to say that string theory is just another one of these ideas with no basis in experimental science...

    Re-Analysis of the Marinov Light-Speed Anisotropy Experiment Reginald T. Cahill School of Chemistry, Physics and Earth Sciences, Flinders University, Adelaide 5001, Australia E-mail: Reg.Cahill@flinders.edu.au The anisotropy of the speed of light at 1 part in 10^3 has been detected by Michelson and Morley (1887), Miller (1925/26), Illingworth (1927), Joos (1930), Jaseja et al. (1964), Torr and Kolen (1984), DeWitte (1991) and Cahill (2006) using a variety of experimental techniques, from gas-mode Michelson interferometers (with the relativistic theory for these only determined in 2002) to one-way RF coaxial cable propagation timing. All agree on the speed, right ascension and declination of...

    Building Planets: Can’t Make Them, But HurryMay 21, 2009 — Constructing planets is a delicate business.  Trying to get tiny bits of dust to join up into balls has never been found to work.  It has to work fast, though, because unless the whole planet clears its dust lane, it will be dragged into the star in short order.  It seems you can’t get there from the bottom up, and even if you could, you’d be in trouble.  These and other problems with planet-building were discussed this month in two papers in the Annual Review of Earth and Planetary...

    Don't try this at home. Several times a day, for several days, you induce pain in someone. You control the pain with morphine until the final day of the experiment, when you replace the morphine with saline solution. Guess what? The saline takes the pain away.

    Gravity: A Theory in Crisis May 5, 2009 — Note: This is **not** a joke. How could gravity be a theory in crisis? Isn’t gravity one of the best-understood facts of nature? Don’t we all avoid jumping off cliffs because of the law of gravity? Gravity is doing just fine, thank you. It’s our theory of gravity, and the cosmology built on it, that is in crisis – according to a report on PhysOrg today: “Study plunges standard Theory of Cosmology into Crisis.”...
