Ted Cruz Is No Hypocrite. He's Worse.
Updated on February 18 at 2:29 p.m. ET Nero fiddled while Rome burned; Ted Cruz jetted to Cancún.

Researchers observe stationary Hawking radiation in an analog black hole
Black holes are regions in space where gravity is very strong—so strong that nothing that enters them can escape, including light. Theoretical predictions suggest that there is a radius surrounding black holes known as the event horizon. Once something passes the event horizon, it can no longer escape a black hole, as gravity becomes stronger as it approaches its center.
