Since the discovery of black holes, they have inspired images of the universe’s extremities in both scientists and storytellers. Their immense gravity — sucking in any matter and light unfortunate enough to come within grabbing distance — conjures images of crushing death and infinite possibility.

That same gravity, however, creates a well which consumes indiscriminately and from whence nothing can ever emerge. The only trouble is that isn’t the case. Among Stephen Hawking’s many accomplishments was the discovery that black holes actually radiate very slowly and will eventually evaporate. This discovery, while enough to make Hawking famous, threw a wrench in contemporary astrophysics by creating a paradox.

“This [study] shows us the evolution of the QGP and eventually [could] suggest how the early universe evolved in the first microsecond after the Big Bang,” said co-author You Zhou, an associate professor at the Niels Bohr Institute, University of Copenhagen in Denmark in an official statement.

“First the plasma that consisted of quarks and gluons was separated by the hot expansion of the universe. Then the pieces of quark reformed into so-called hadrons. A hadron with three quarks makes a proton, which is part of atomic cores. These cores are the building blocks that constitutes earth, ourselves and the universe that surrounds us.”

In a new study, scientists say they can explain dark matter by positing a particle that links to a fifth dimension.

(Updated version of the previous article.)

While the “warped extra dimension” (WED) is a trademark of a popular physics model first introduced in 1999, this research, published in The European Physical Journal C, is the first to cohesively use the theory to explain the long-lasting dark matter problem within particle physics.

Although dark matter is a central part of the standard cosmological model, it’s not without its issues. There continue to be nagging mysteries about the stuff, not the least of which is the fact that scientists have found no direct particle evidence of it.

Despite numerous searches, we have yet to detect dark matter particles. So some astronomers favor an alternative, such as modified Newtonian dynamics (MoND) or modified gravity model. And a new study of galactic rotation seems to support them.

The idea of MoND was inspired by galactic rotation. Most of the visible matter in a galaxy is clustered in the middle, so you’d expect that stars closer to the center would have faster orbital speeds than stars farther away, similar to the planets of our solar system. What we observe is that stars in a galaxy all rotate at about the same speed. The rotation curve is essentially flat rather than dropping off. The dark matter solution is that galaxies are surrounded by a halo of invisible matter, but in 1983 Mordehai Milgrom argued that our gravitational model must be wrong.
