A retired cosmological theory should be given a second chance at explaining anomalies in our Universe, according to theoretical physicist Rajendra Gupta from the University of Ottawa in Canada.
Scientists have for the first time observed the early universe running in extreme slow motion, unlocking one of the mysteries of Einstein's expanding universe.
Astronomers have made a discovery that confirms the existence of gravitational waves, which sound like the hum at a large gathering. These ripples in space-time were proposed by Albert Einstein over a century ago.
There could have been two scenarios with the two Big Bangs. The Hot Big Bang, as in the standard picture, creates the hot plasma of visible matter and radiation and the dark matter, however, could have been created in a later, ‘darker’ Big Bang.
According to a new U.S. research it appears that the Universe is actually getting hotter as time goes on. The mean temperature of cosmic gas has increased more than 10 times and reached about 2.2 million K.
Recently scientists suggested that have suggested the universe may be hundreds of millions of years younger. However a new observations suggest the universe is still about 13.8 billion years old.
One of the core assumptions of astronomy is that the universe appears the same in all directions, or it is isotropic. However, a recent study suggests that may not be the case.
Years of observational data, cosmological models and physics suggest the Universe is flat. However, a recent study suggests that the Universe is actually curved and closed, like an inflating sphere.
Astronomers have made a new measurement of how fast the universe is expanding, using an entirely different kind of star than previous endeavors. The revised measurement may lead to a new interpretation of the universe's fundamental properties.
It has taken researchers almost three years to produce this deepest image of the Universe ever taken from space, by recovering a large quantity of ‘lost’ light around the largest galaxies in the iconic Hubble Ultra-Deep Field.
