A physicist investigating black holes has found that, in an expanding universe, Einstein's equations require that the rate of the universe's expansion at the event horizon of every black hole must be a constant, the same ...
Using a specially designed 3D printed vacuum system, scientists have developed a way to "trap" dark matter with the aim of detecting domain walls. This will be a significant step forwards in unraveling some of the mysteries ...

A small team of astronomers from Yunnan University, the University of Utah, New Mexico State University, and the University of St Andrews has created a new model of the Milky Way galaxy based on the results of their census ...
A pair of astrophysicists with Princeton University and the SLAC National Accelerator Laboratory found possible evidence of dark matter particles colliding. In their study, published in Physical Review Letters, Carlos Blanco ...
In humankind's ever-ticking pursuit of perfection, scientists have developed an atomic clock that is more precise and accurate than any clock previously created. The new clock was built by researchers at JILA, a joint institution ...
