Researchers investigate dark photons as alternatives to dark matter, aiming to detect these particles through experiments involving the conversion of light.
Galactic clusters may be key to testing competing theories of dark matter and dark energy
Scientists propose a modified cosmological model that challenges the existence of dark matter and dark energy.
Quantum tunneling may have ruled out a popular theory of dark matter
The composition of dark matter remains a mystery, but a new theory involving quantum tunneling may have eliminated some candidates.
Could dark matter be measured around black holes?
Dark matter could be aggregating around black holes, providing a possible means of indirectly measuring its properties.
Modified theory of gravity eliminates the need for dark energy
Many physicists are still skeptical that dark energy can fully explain gravity, and are therefore exploring alternative theories.
String theory may offer an alternative to dark energy
A new study evaluates gravity using string theory, a promising candidate for describing particle interactions at their most fundamental level.
Could black holes be dark energy?
Astronomers looking at how black holes grow over time may have found the answer to one of the biggest problems in cosmology.
Searching for dark matter in our solar system
Sending atomic and nuclear clocks into the inner reaches of our solar system could help scientists find proof of elusive dark matter.
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.
Dark matter from quantum gravity
Researchers at the Southern University of Science and Technology in China ask if gravitons can be promising candidates for dark matter components.
