Time is a slippery thing, as profound thinkers like physicist Albert Einstein and, well, fictional time traveler Dr. Who plainly understood. The latter, in a 2007 episode of the British sci-fi series, accurately described time as “wibbly wobbly.”

Scientists made that point anew on Monday in a study that used observations of a ferocious class of black holes called quasars to demonstrate “time dilation” in the early universe, showing how time then passed only about a fifth as quickly as it does today.
