Why the universe might be a hologram

A quarter century ago, physicist Juan Maldacena proposed the AdS/CFT correspondence, an intriguing holographic connection between gravity in a three-dimensional universe and quantum physics on the universe's two-dimensional ...

Researchers use supercomputer to investigate dark matter

A research team from the University of California, Santa Cruz, have used the Oak Ridge Leadership Computing Facility's Summit supercomputer to run one of the most complete cosmological models yet to probe the properties of ...

Astronomers go hunting for mysterious q-balls

Our universe may feature large, macroscopic clumps of dark matter known as q-balls. These q-balls would be absolutely invisible, but they may reveal their presence through tiny magnifications of starlight.

Black hole found hiding in star cluster outside our galaxy

Using the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers have discovered a small black hole outside the Milky Way by looking at how it influences the motion of a star in its close vicinity. ...

Is the nearest star cluster to the sun being destroyed?

Data from ESA's Gaia star mapping satellite have revealed tantalizing evidence that the nearest star cluster to the sun is being disrupted by the gravitational influence of a massive but unseen structure in our galaxy.

Image: Hubble's treasure chest of galaxies

Galaxies abound in this spectacular Hubble image; spiral arms swirl in all colors and orientations, and fuzzy ellipticals can be seen speckled across the frame as softly glowing smudges on the sky. Each visible speck of a ...
