A team of researchers from MIT, Harvard University and the University of Belgrade has found a way to make photons repel each other inside a cloud of ultracold atomic gas. In their paper published in the journal Nature Physics, ...
Computer simulations conducted by astrophysicists at Tohoku University in Japan, have revealed a new theory for the origin of supermassive black holes. In this theory, the precursors of supermassive black holes grow by swallowing ...
