Comparing algorithms used to model spinning neutron stars, scientists hope to better understand the physics of the elementary particles that make them up.
Detecting ultralight dark matter particles using supermassive black holes
Is it time to start looking for alternatives to WIMPs?
Explaining the Universe’s accelerated expansion without dark energy
A modification to the theory of general relativity makes it consistent with observable astronomical data without the need for dark energy.
A breakthrough in nuclear fusion announced
After decades of experimentation, US scientists achieve ignition in a controlled fusion experiment for the first time.
General relativity may need tweaking on the grand scale of the Universe
Conflict between theory and observational evidence suggests a missing ingredient in our understanding of the early Universe.
A quark star may have just been discovered
More confirmation needed to see if recently discovered object is a quark star.
Black hole orbit oscillations shore up general relativity
Oscillations measured in the orbits of a pair of black holes have once again helped confirm predictions made using general relativity.
The road towards the first image of a black hole
Imaging a black hole is not an easy thing, it takes years of experiments, collaborations, grants, planning, and no small amount of luck.
Is the Universe running out of stars?
Astronomers are discovering that the rate of star formation in the universe is dropping, and they want to know why.
String theory used to describe the expanding universe
To address unknown quantum gravitational effects in the early universe, physicists have recruited string theory to help solve the problem.
