Many physicists are still skeptical that dark energy can fully explain gravity, and are therefore exploring alternative theories.
A new study evaluates gravity using string theory, a promising candidate for describing particle interactions at their most fundamental level.
Astronomers looking at how black holes grow over time may have found the answer to one of the biggest problems in cosmology.
A modification to the theory of general relativity makes it consistent with observable astronomical data without the need for dark energy.
Bright bursts of radio waves help astronomers locate a type of matter that researchers have been searching for for the past 30 years.
Gravitational waves could be the key to imaging elusive primordial black holes born in the first moments of our Universe.
It’s looking less and less likely that the Hubble tension is a result of observational errors.
Enhanced experimental precision has the potential to either confirm or dispel uncertainties surrounding the Standard Model of Physics.
Using quasars as ticking cosmic clocks, scientists took a journey back in time, discovering time progressed five times slower just after the Big Bang.
A new approach to understanding gravity helps eliminate some discrepancies inherent in general relativity.
