Will it go Big Bang Again ?
Joel Achenbach's Washington Post's article today asks "Will the Universe Go Crunch, or Will 'Dark Energy' Rip It Apart? Either Way, Your Head Will Pop."
Answer?
"We're not sure if the universe will keep expanding or start contracting. We don't know if The End, if there ever is such a thing, is many billions of years away or many trillions of years away. We don't know the nature of dark energy, this strange force that's shaping the universe. We don't know if constants are constant. We don't know why there are laws of physics. We don't know why there's something rather than nothing."
