Our Universe May Have Emerged from a Black Hole in a Higher Dimensional Universe

New research from theoretical physicists at the Perimeter Institute proposes that our universe may have emerged from a black hole in a higher-dimensional universe. The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it? Three Perimeter Institute researchers have […]

Perimeter Institute for Theoretical Physics Examines the Multiverse Hypothesis

In several new studies and a short video, researchers from the Perimeter Institute for Theoretical Physics detail their work on the multiverse hypothesis. Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science. Never […]

ideal time to study the cosmos was more than 13 billion years ago

The time to study the cosmos is now. New calculations show that the expansion of the cosmos is accelerating, galaxies are being pushed beyond our horizon and the scale of gravitationally unbound structures is growing larger and will eventually stretch beyond our horizon as well. Cambridge, Massachusetts – The universe is a marvelously complex place, […]

Gamma ray bursts (GRBs) have been routinely observed by orbiting observatories, such as NASA’s Fermi and Swift spacecraft, and astronomers are planning on using them as cosmic flashbulbs to probe the details of the early Universe. The researchers published their findings in the journal Nature today. GRBs are seen almost daily, and are thought to […]

A plot of the location in the sky of galaxies between about 280-420 million light-years of Earth

Once scientists realized that their understanding of the distribution of galaxies was incorrect, researchers began studying the large scale structure of the universe to better understand the sum of all movements in relation to Earth. Now some forty years later, a newly published study gives an unprecedented account of all of the normal matter within […]

A rare cosmic zoom lens, which uses the gravity of a large mass to magnify light from distant objects, has allowed a team of US and European astronomers to spot a galaxy so remote that its light was emitted 490 million years after the Big Bang, which is 3.6% of the Universe’s current age. The […]

bolshoi-simulation

The Bolshoi simulation is the most accurate cosmological simulation of the evolution of the large-scale structure of the universe. Larger simulations, including the BigBolshoi and Multidark, run at a volume 64 times bigger than Bolshoi and have just been publicly made available to astronomers and astrophysicists. The Bolshoi simulation used data from the Wilkinson Microwave […]

While it might sound like science-fiction, the idea that the Universe is embedded in a broader multidimensional space is something that cosmologists have been pondering. The cosmos might exist in parallel with outer universes in other sets of dimensions. These universes are called braneworlds. If this is an accurate description of what’s happening, then the […]

Timeline-inflationary-universe

There are quite a few challenges for cosmologists trying to discover evidence of what it was like early in the life of our universe, but while the inflationary universe scenario was an almost universally accepted model, there are still problems, especially for observational astrophysicists who don’t see any evidence of a flat universe, as inflation […]

Universe Collide

While it’s a well-known fact that there’s an upcoming Andromeda-Milky Way collision in 3 to 5 billion years, Stephen Hawking has stated that we should look to a collision between universes in the distant past of our own universe for explanations of why physical constants seem so fine-tuned to the values required for life to […]
