A higher-dimensional model can help explain cosmic acceleration without dark energy
Dark energy remains among the greatest puzzles in our understanding of the cosmos. In the standard model of cosmology called the Lambda-CDM, it is accounted for by adding a cosmological constant term in Einstein's field equation ...
Experiment uses quantum techniques to stimulate photons, enhancing search for dark matter
Scientists cannot observe dark matter directly, so to "see" it, they look for signals that it has interacted with other matter by creating a visible photon. However, signals from dark matter are incredibly weak. If scientists ...
