We have no idea what dark matter is, other than it’s some source of gravity that is completely invisible but exerts way more pull that all of the regular matter. More than all of the stars, all of the gas, all of the black holes…unless...

A fun nightmare sci-fi scenario is the sun being consumed by a black hole. Fortunately the chance of a black hole randomly wandering into our solar system is pretty tiny. That’s good news. But what if it’s already here, hiding in the...

One of the most fundamental physics facts is that the speed of light in a vacuum is constant for all observers. But can we really be sure that the speed of light wasn’t different in the past, or perhaps in other parts of the universe? In...

The primary characteristic that defines black holes is in the name. Black holes are black. The gravitational pull at the event horizon is so powerful that not even light can escape. In this case, black means absence of light. We also...
