“Is spacetime a fluid?” Leading physicists query

Summary of the spacetime issues discussed in this article. One can use photons and astronomical objects as test particles to measure spacetime over 22 orders of magnitude in scale, ranging from the cosmic horizon (probing the global topology of and curvature of space - top) to distant supernovae (giving evidence of dark energy) down to galaxies (giving evidence for dark matter), galactic nuclei and binary stellar systems (giving evidence for black holes)

Quarks in six-packs: Exotic Particle Confirmed

For a long time, physicists were only able to reliably verify two different classes of hadrons: baryons and mesons. Experiments performed at Jülich’s accelerator COSY have now shown that, in fact, another class of exotic particles made up of six quarks exists.

New research shows that gravitational fields around black holes might eddy and swirl

This artist's concept depicts a supermassive black hole at the center of a galaxy. The blue color here represents radiation pouring out from material very close to the black hole. The grayish structure surrounding the black hole, called a torus, is made up of gas and dust.
