Best known to astronomical trivia buffs as the man who coined the term “black hole,” University of Texas physicist John A. Wheeler died this morning at the age of 96. Wheeler “was legendary for his way with words, coining such terms as wormholes, quantum foam, black holes, and the wave function of the...

Did a parent, boyfriend/girlfriend, spouse, supervisor, etc., ever say to you in an argument, “You’re not the center of the universe, you know!” Well, sorry to disappoint, but you’re not the center of the galaxy either.

Well, Wednesday was my shortened day. I was at the meeting for only the morning. In that time I went to three press conferences and wandered around some of the posters … all before 1:15 p.m. Then I had to bug off to grab my shuttle to the airport. Today was a lot of high-energy and cosmology — the really...

At a press conference yesterday morning, several scientists spoke about their recent research into these objects, whose gravity...
