    New measurements confirm cosmos should have self-destructed if Big Bang true! Despite the organization’s $1.24 billion annual budget for 2017, the physicists at CERN, the European Organization for Nuclear Research, are being forced to admit failure in their latest effort to explain why any of us are here. Indeed, why there’s even a “here” here at all. “The universe should not actually exist,” said Christian Smorra, a physicist at CERN’s Baryon–Antibaryon Symmetry Experiment (BASE) collaboration. CERN, founded in 1954, features a circular tunnel some 17 miles around that houses a particle accelerator, which uses peak energy of 14 trillion electron...
  • Is The Inflationary Universe A Scientific Theory? Not Anymore

    We are made from stretched quantum fluctuations. At least that’s cosmologists’ currently most popular explanation. According to their theory, the history of our existence began billions of years ago with a – now absent – field that propelled the universe into a phase of rapid expansion called “inflation.” When inflation ended, the field decayed and its energy was converted into radiation and particles which are still around today.

    We know, to the best of our senses and instruments, that the universe exists. How did it come into reality 13.8 billion years ago? In other words, what caused the Big Bang? Roughly speaking, there are two possibilities: “nothing” caused the universe to come into being or “something” triggered it into existence.
  • There have probably been trillions of alien civilizations, and yet we may still never see one

    Sorry, everybody. We’re just not that special. In more than five decades of scanning the heavens, the search for extraterrestrial intelligence (SETI) has found no sign of alien life. Yet now two American astronomers, in the scientific equivalent of a back-of-the-envelope calculation, are estimating that over the course of its history the universe has seen at least half a trillion technologically advanced species. Remember, 420 billion intelligent civilizations is the “pessimistic” estimate. But sadly—or happily, depending on your view of aliens—it doesn’t make us any less alone.

    In case you haven't been paying attention, it has been a pretty exciting last few years for what astronomers call the "observable universe." It's been a particularly rewarding stretch for Albert Einstein too, even though he died in 1955. For instance, last year astrophysicists made the first observations of gravitational waves, which Einstein, exactly 100 years ago, predicted should exist. These waves, which I won't even try to explain, were observed when two black holes crashed into one another and merged. A black hole is formed from matter so dense, and with gravity so strong, that anything near it -...

    Astronomy Picture of the Day ^ | 15 March 2017 | Hubble Legacy Archive, NASA, ESA
    Explanation: Stars are forming in the gigantic dust pillar called the Cone Nebula. Cones, pillars, and majestic flowing shapes abound in stellar nurseries where natal clouds of gas and dust are buffeted by energetic winds from newborn stars. The Cone Nebula, a well-known example, lies within the bright galactic star-forming region NGC 2264. The Cone was captured in unprecedented detail in this close-up composite of several observations from the Earth-orbiting Hubble Space Telescope. While the Cone Nebula, about 2,500 light-years away in Monoceros, is around 7 light-years long, the region pictured here surrounding the cone's blunted head is a mere...

    In “Physics: A cosmos in the lab,” a review of A Big Bang in a Little Room: The Quest to Create New Universes by Zeeya Merali, cosmologist Andreas Albrecht writes at Nature, The question of cosmic origins, and the possibility that humans might create new universes, can connect with religious concerns. These form a substantial thread through A Big Bang in a Little Room that significantly reduced the book’s appeal to me. I am an atheist. I respect that many people are deeply religious (some are very close to me) and that religion can have a positive, even beautiful,...
  • The Most Persuasive Scientific Reason to Believe?

    What scientific argument for the truth of Christianity do you find the most persuasive? As I contemplated this question, my answer was big bang cosmology. Here’s why. All big bang models include three essential features: (1) constant laws of physics throughout the universe; (2) a dynamic universe, one either expanding or contracting; and (3) a beginning to the universe. Remarkably, the biblical description matches these essential features. Constant Laws of Physics The scientific enterprise depends on a universe governed by constant laws of physics. If measurements today have no bearing on what happened yesterday or will happen tomorrow, no scientific...

    Stargazers are in for a triple treat: Friday night will feature a type of lunar eclipse, the Full Snow Moon, and even a comet. You’ve likely heard of a “supermoon,” when the full moon appears brighter than usual because it’s closer to Earth. Friday night, something different will happen, in effect. The full moon will be darker. That’s because the Earth’s natural satellite will experience something called a penumbral eclipse. A full lunar eclipse happens when the Earth is right in between the sun and the moon, casting its shadow onto the moon. In a penumbral eclipse, it’s just the...
  • We Still Don't Know How Fast The Universe Is Expanding

    Forbes ^ | 12 Jan, 2017 | Ethan Siegel
    Once we discovered that the Universe was expanding, the next scientific step was to determine what the rate of expansion was. Despite the fact that it's been more than 80 years, we still don't have agreement on how fast that rate actually is. By looking at the largest cosmic scales and the oldest signals -- the leftover radiation from the Big Bang and the largest-scale galaxy correlations -- we get one number for the rate: 67 km/s/Mpc. But if we look at individual stars, galaxies, supernovae and other direct indicators, we get another number: 74 km/s/Mpc. The uncertainties are very...
  • Thou Art My Son...Psalm 1 and 2 pt 9

    …I will declare the decree: the LORD hath said unto me, Thou art my Son; this day have I begotten thee. Ask of me, and I shall give thee the heathen for thine inheritance, and the uttermost parts of the earth for thy possession.Thou shalt break them with a rod of iron; thou shalt dash them in pieces like a potter’s vessel.(Psalm 2:7-9)In its original context Psalm 2 is a coronation psalm.

    Since the Large Hadron Collider at CERN turned on, it’s brought with it an incredible slew of results. Large numbers of rare, exotic and unstable particles have been created, and their decays have been measured to unprecedented precision. The Higgs boson has been created and observed to have a mass of 126 GeV/c2, branching and decaying in exactly the ratios the Standard Model predicts. As it now stands, we’ve detected every particle and antiparticle predicted by the most successful particle physics theory of all time. Unless we get hit by a big physics surprise, the LHC will become renowned for...

    This could change everything. Back in 2011, three astronomers were awarded the Nobel Prize in Physics for their discovery that the Universe wasn’t just expanding - it was expanding at an accelerating rate. The discovery led to the widespread acceptance of the idea that our Universe is dominated by a mysterious force called dark energy, and altered the standard model of cosmology forever. But now physicists say this discovery might have been false, and they have a much larger dataset to back them up. For a bit of background on the 2011 Nobel Prize in Physics, it was shared between...

    A new study from a team of international astronomers, led by astrophysicists from the University of Nottingham with support from the Royal Astronomical Society (RAS), has produced some astounding results: The universe contains at least two trillion galaxies, 10 times more than the highest previous estimates. What's more, the new study suggests that 90 percent of all galaxies are hidden from us, and only the remaining 10 percent can be seen at all, even with our most powerful telescopes. The paper detailing the study was published today in the Astrophysical Journal. "We are missing the vast majority of galaxies because...

    A new record for the most distant galaxy cluster has been set using NASA’s Chandra X-ray Observatory and other telescopes. This galaxy cluster may have been caught right after birth, a brief, but important stage of evolution never seen before. The galaxy cluster is called CL J1001+0220 (CL J1001 for short) and is located about 11.1 billion light years from Earth. The discovery of this object pushes back the formation time of galaxy clusters – the largest structures in the Universe held together by gravity – by about 700 million years. “This galaxy cluster isn’t just remarkable for its distance,...

    If the universe was infinitely old, as we used to assume, then it must be filled with an infinite number of stars and galaxies. So why is the night sky not completely lit up by the light from these stars? This question was first asked by the nineteenth century astronomer Heinrich Olbers, and the answer is, because of the age of the universe, not all of the photons have had enough time to reach us yet. The amount of universe we are able to see is called the observable universe, and according to a pair of astrophysicists, it just got...

    Since the mid-1970s, modern physics has rested on the knowledge of four fundamental forces of nature: gravity, electromagnetism, the strong nuclear force, and the weak nuclear force. Now scientists are on the verge of discovering a fifth force of nature, which could change the field of physics forever. According to a recent paper published by University of California physicists in the peer-reviewed journal Physical Review Letters, what physicists thought was a new particle of matter could be a new force altogether.
