Surprise Black Hole Discovery Could Explain How They Grew So Enormous in The Early Universe

Posted by in categories: cosmology, materials

In recent years, cosmologists peering back to the very dawn of our Universe have discovered something peculiar. A whole bunch of supermassive black holes — in a time thought way too early for such massive objects to have formed.

Exactly how they got to be so freaking huge so quickly is a heck of a puzzle — but a new surprise discovery might have delivered an answer. The disc of dust and gas around a supermassive black hole is moving in such a way that it’s slurping down material faster than it would normally.

That means it’s gaining mass faster than expected — which in turn could explain what happened in the earliest days of our Universe.

Scientists may have discovered parallel universe

Posted by in categories: astronomy, cosmology, physics, science, space

Scientists believe they may have caught a glimpse of a parallel universe bumping up against ours.

They’ve seen hints in signals from the most distant points of the universe that suggest the fabric of our universe has been disrupted by another incredibly different universe. Their analysis may be the proof for the multiverse theory.

According to researchers: “Dr Ranga-Ram Chary examined the noise and residual signals in the cosmic microwave background left over from the Big Bang (pictured) and found a number of scattered bright spots which he believes may be signals of another universe bumping into our own billions of years ago.”

At least that’s the tentative conclusion researchers have come to. According to some cosmological theories, collisions of alternative universes should be possible. Theories conclude that our universe is like a bubble among many.

Stretched photons recover lost interference

Posted by in categories: computing, cosmology, particle physics, quantum physics

The smallest pieces of nature—individual particles like electrons, for instance—are pretty much interchangeable. An electron is an electron is an electron, regardless of whether it’s stuck in a lab on Earth, bound to an atom in some chalky moon dust or shot out of an extragalactic black hole in a superheated jet. In practice, though, differences in energy, motion or location can make it easy to tell two electrons apart.

One way to test for the similarity of particles like electrons is to bring them together at the same time and place and look for interference—a that arises when particles (which can also behave like waves) meet. This interference is important for everything from fundamental tests of quantum physics to the speedy calculations of quantum computers, but creating it requires exquisite control over particles that are indistinguishable.

With an eye toward easing these requirements, researchers at the Joint Quantum Institute (JQI) and the Joint Center for Quantum Information and Computer Science (QuICS) have stretched out multiple photons—the quantum particles of light—and turned three distinct pulses into overlapping quantum waves. The work, which was published recently in the journal Physical Review Letters, restores the interference between photons and may eventually enable a demonstration of a particular kind of quantum supremacy—a clear speed advantage for computers that run on the rules of quantum physics.

Black holes might not crush you after all—they could be even weirder than that

Posted by in categories: cosmology, singularity

Just when you thought one of the most bizarre things in space was something that eats massive amounts of light and energy and would probably shred you with its gravitational forces, what if it was something even harder to imagine?

Black holes are supposed to have a singularity—a point that is so small and dense we can’t even fathom it—in the middle of all that swirling light and gas. But what if at least some cosmic phenomena that look like black holes are actually cosmic objects full of dark energy? That is what astrophysicists Kevin Croker and Joel Weiner of the University of Hawai’i at Manoa recently published in a study in The Astrophysical Journal that tries to prove these hypothetical Generic Objects of Dark Energy (GEODEs) exist.
