No matter what Martin Rees or anyone else says, physics dictates that the world is safe. The Large Hadron Collider is the world’s most powerful particle accelerator. An aerial view of […]
Lasers, mirrors, and computational advances can all work together to push ground-based astronomy past even the limits of Hubble. One of the most profoundly remarkable properties about our atmosphere is that […]
In a state-of-the-nation speech just weeks before Russia’s presidential election, President Vladimir Putin claimed his country had two new nuclear-powered weapons systems.

Both effects could be responsible for a redshift. But only one makes sense for our Universe. In physics, like in life, there are often multiple solutions to a problem that […]
Every physical theory has constants in it. The gravitational constant is remarkably uncertain. When we first began formulating physical laws, we did so empirically: through experiments. Drop a ball off […]
