A new theory suggests that dark matter may be more dynamic than we currently assume.

The telescope may give us a long-awaited glimpse at what lies behind the cosmic veil of the Milky Way’s super-massive black hole.

Scientists have used telescopes from all over the earth to edge closer to imaging the supermassive back hole (SMBH) at the center of the Milky Way, reports Newsweek. An SMBH, the largest type of black hole, is found in the middle of almost all known massive galaxies. The SMBH that inhabits our galaxy is located at approximately the galactic center of the galaxy (18hrs, −29 deg), and it is known as Sagittarius A*.

Pronounced Sagittarius A-star, this spiral structure within Sagittarius A West and Sagittarius A East “contains an intense compact radio source.” It’s located approximately 26,000 light years away from earth, and it can’t be seen by normal optics. Instead, Sagittarius A* lies hidden beneath the Milky Way’s enormous dust clouds.

Astronomer Misty Bentz would like you to know that black holes don’t suck. “They’re not cosmic vacuum cleaners going around and sucking everything in,” she says. “They just use gravity the same way everything else does.”

Instead of a cosmic drinking straw, a black hole is a place in the universe that is so massive and dense that anything caught in its significant gravitational pull is unable to escape.

Black holes have been in the news a lot lately, from the swarm found near the supermassive black hole at the center of our galaxy, to the fastest-growing black hole ever observed, which ingests the equivalent of the mass of our Sun every two days, to the most distant black hole ever detected, dating to the dawn of the universe. From their inception to their potential demise far in the future, black holes are a fascinating part of our universe. Here’s their story as we understand it now, from start to finish.

Based on complex simulations of quantum chromodynamics performed using the K computer, one of the most powerful computers in the world, the HAL QCD Collaboration, made up of scientists from the RIKEN Nishina Center for Accelerator-based Science and the RIKEN Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) program, together with colleagues from a number of universities, have predicted a new type of “dibaryon”—a particle that contains six quarks instead of the usual three. Studying how these elements form could help scientists understand the interactions among elementary particles in extreme environments such as the interiors of neutron stars or the early universe moments after the Big Bang.

Particles known as “baryons”—principally protons and neutrons—are composed of three quarks bound tightly together, with their charge depending on the “color” of the quarks that make them up. A dibaryon is essentially a system with two baryons. There is one known dibaryon in nature—deuteron, a deuterium (or heavy-hydrogen) nucleus that contains a proton and a neutron that are very lightly bound. Scientists have long wondered whether there could be other types of dibaryons. Despite searches, no other dibaryon has been found.

The group, in work published in Physical Review Letters, has now used powerful theoretical and computational tools to predict the existence of a “most strange” dibaryon, made up of two “Omega baryons” that contain three strange quarks each. They named it “di-Omega”. The group also suggested a way to look for these strange particles through experiments with heavy ion collisions planned in Europe and Japan.

Black holes formed from the death of a single star may collect and collide with other black holes to form even more-massive objects.

It’s growing so rapidly that it’s shining thousands of times more brightly than an entire galaxy.

A “supermassive” black hole swallowing up the mass of our sun every two days has been found by Australian astronomers.

Astronomers at the Australian National University (ANU), led by Dr Christian Wolf of the Research School of Astronomy and Astrophysics, found the fastest-growing black hole known in the universe by looking back more than 12 billion years to what they call “the early dark ages of the universe.”

According to the current dominant theory, if there are other universes out there, they’re not likely to have life. But now an international team of researchers has demonstrated that the Multiverse is more hospitable than we thought.

The Multiverse hypothesis — wherein our observable Universe is just one of many universes — is a proposed explanation for the not-large-enough amount of dark energy in the empty space in our Universe.

We don’t really know what dark energy is — it’s the name we give to the force that drives the expansion of our Universe, which, contrary to pretty much everything else we observe, accelerates over time instead of slowing down.

Two new studies analyzing the relationship between dark energy, life, and the multiverse suggest it’s possible life exists in universes outside our own. Though the idea of the multiverse is not new, the concept of our universe being extraordinarily special might not be true.
