A new study suggests that dark energy might not be real after all. But other scientists have found major flaws with this bold claim.
A super telescope has begun the most detailed survey of the Universe ever undertaken.
A mind-bending new theory claims to make sense not just of the expanding universe and extra dimensions, but string theory and dark energy as well. According to the new model, proposed in the journal Physical Review Letters by researchers from Uppsala University, the entire universe is riding on an expanding bubble in an “additional dimension” — which
During the 1930s, astronomers came to realize that the Universe is in a state of expansion.
When it comes to scientifically mysterious concepts that begin with the word “dark,” dark matter attracts most of the public attention.
A new study may help reveal the nature of dark energy, the mysterious substance that is pushing the universe to expand outward. Dark energy may emerge from fluctuations in the nothingness of empty space, a new hypothesis suggests.
A team of researchers from the Department of Physics and Astronomy at the University of British Columbia, Canada, has tackled the question ‘what causes the slow accelerating expansion of the Universe’ in a study that tries to resolve a major incompatibility issue between two theories: quantum mechanics and Einstein’s theory of general relativity.
Long ago, physicists identified and categorized the components of the visible universe. Up until recently, 16 particles formed everything in the known universe. But now, thanks to the efforts of physicists at CERN working with the Large Hadron Collider (LHC), we have added another particle, the Higgs boson, to the Standard Model of physics.
