Scientists Use Neutrons To Search For Dark Energy

Vienna University of Technology With neutrons, scientists can now look for dark energy in the lab All the particles we know to exist make up only about five per cent of the mass and energy of the universe. The rest – "Dark Matter" and...

Scientists Make The Most Precise Measurment Of Early Universe Yet
2014-04-08 07:50:37

Lawrence LeBlond for redOrbit.com - Your Universe Online Two recent studies of the early Universe using the Baryon Oscillation Spectroscopic Survey (BOSS), a component of the third Sloan Digital Sky Survey (SDSS-III), have made the most accurate measurement of the rate of expansion in the early Universe to date. BOSS has pioneered the use of quasars to map density variations in intergalactic gas at high redshifts to trace the structure of the young Universe. BOSS helps scientists chart...

Dark Energy Hidden Behind Phantom Fields
2014-03-28 14:30:26

FECYT - Spanish Foundation for Science and Technology Quintessence and phantom fields, two hypotheses formulated using data from satellites, such as Planck and WMAP, are among the many theories that try to explain the nature of dark energy. Now researchers from Barcelona and Athens suggest that both possibilities are only a mirage in the observations and it is the quantum vacuum which could be behind this energy that moves our universe. Cosmologists believe that some three quarters of...

MONTREAL , March 7, 2014 /PRNewswire/ -- According to the Pantheory Research Organization, a new study of type 1a supernova data has concluded, for the first time, that dark energy probably does not exist. The paper is entitled "An Alternative Universe-Scale Analytic Metrology and Related Cosmological Model." The paper was published in the February 2014 issue of the journal of Applied Physics Research, by the Canadian Center of Science and Education. This new research study...

Non-Astronomy Scientists May Help Answer Cosmology Conundrum
2013-11-28 06:41:07

April Flowers for redOrbit.com - Your Universe Online Measuring the invisible and intangible is a challenge for sure, but scientists have made inroads on one front: the study of dark matter and dark energy, two of the most mysterious substances in the cosmos. Although dark matter is intermixed with normal matter, it gives off no light, making it impossible to see. Dark energy presents even more challenges, yet researchers believe it works against gravity to pull our universe apart at...

Study Uses Big Bang Afterglow To Show Earth Has No Special Place In Expanding Universe
2013-11-07 07:53:48

Dartmouth College In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion. While the findings don't explain the cosmic speed-up, they eliminate one provocative possibility that our planet, solar system and galaxy are at the center of the universe and that there is no dark energy. The findings appear in the journal Physical Review D. The 2011 Nobel Prize was awarded for the discovery that the expansion of the...

ESA Shutting Down Planck Space Telescope
2013-10-18 16:29:49

Brett Smith for redOrbit.com – Your Universe Online After for four years surveying the Universe for the European Space Agency (ESA), the Planck space telescope’s Low Frequency Instrument will be turned off on Saturday, having completed its science operations on October 3. The telescope’s High Frequency Instrument ended operation in January 2012, after conducting five all-sky surveys. With some operational loose ends still to tie up, Planck will finally be switched off next week....

Higgs Boson Dark Energy

John P. Millis, PhD for redOrbit.com - Your Universe Online For the better part of two decades, the greatest fundamental question facing physics and cosmology has been, quite simply, what is dark energy? Detailed observations of galaxies in our Universe reveal the expansion of the Universe is accelerating. Even after accounting for all of the normal matter, radiation, and even the theorized dark matter out there, there still simply isn't enough "stuff" to explain the dynamics of the...

3D Map Of The Large-Scale Structure Of The Universe Released
2013-08-08 13:58:29

Subaru Telescope An international team led by astronomers from Kyoto University, the University of Tokyo and the University of Oxford has released its first version of a 3D map of the Universe from its FastSound project (Note 1), which is surveying galaxies in the Universe over nine billion light years away. Using the Subaru Telescope's new Fiber Multi-Object Spectrograph (FMOS, Note 2), the team's 3D map includes 1,100 galaxies and shows the large-scale structure of the Universe nine...

Cosmic Microwave Background Radiation Data Allows Furthest Look Back Through Time
2013-08-08 04:23:16

April Flowers for redOrbit.com - Your Universe Online The best way to solve a mystery, as any detective can tell you, is to revisit the scene where it began and look for clues. Scientists, searching for the mysteries of our universe, are trying to go back as far as they can to the Big Bang. Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) conducted a new analysis of cosmic microwave background (CMB) radiation data to take the furthest look back yet. This look - 100...

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

Quintessence (Dark Energy) -- Quintessence or dark energy is a hypothetical form of energy postulated to exist in order to explain observations of an accelerating universe. This energy would act like a vacuum pressure, pushing things apart. Other attempts to explain these recent observations involve a non-zero cosmological constant, which has the same effect. Indeed, sometimes quintessence is said to result in a non-zero cosmological constant, and conversely a non-zero cosmological...

Wilkinson Microwave Anisotropy Probe (WMAP) -- The Wilkinson Microwave Anisotropy Probe (WMAP) was launched on June 30, 2001 at 3:46 p.m. EDT at Cape Canaveral Air Force Station, Florida, USA. The goal of WMAP was to map out minute differences in the Cosmic Microwave Background (CMB) radiation which would help test theories of the nature of the universe. On February 11, 2003, the public relations group from NASA made a press release regarding the age and composition of the universe....
