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.
Swedish researchers have devised a new model for the Universe, that may solve the enigma of dark energy. They proposes a new structural concept of a universe that rides on an expanding bubble in an additional dimension.
UK researcher, Jamie Farnes, suggests both dark energy and matter can be unified into a single substance — a negative-mass ‘dark fluid.’ The theory may also prove right a prediction that Albert Einstein made 100 years ago.
The theory, which was submitted for publication before Hawking's death earlier this year, is based on string theory and predicts the universe is finite and far simpler than many current theories about the big bang say.
Lengthy observations by the Hubble Space Telescope indicate the universe is expanding faster than predicted by standard models and that Einstein’s cosmological constant, thought by many to define dark energy, may not be so constant after all.
The simulation consists of 18 simulations covering various scales - each a cubic mock-up of space up to 1 billion light years wide - tracing the evolution of the Universe from just after the Big Bang into the future.
Even though we cannot physically access the 4D world, being aware of its existence will pave the way to future discoveries and a better understanding of our Universe.
