POPS'Dark energy' may mean the end of the Universe And, they believe, a strange, yet-to-be-detected form of energy called dark energy pervades the Universe, which would explain why the sum of all the visible sources of energy fall way short of what should be out there. Dark energy, goes the thinking, is a result of the Big Bang and is accelerating the Universe's expansion.

The energy shift from the decay would destroy everything in the Universe, "wiping the slate clean," says Lawrence Krauss of Case Western Reserve University in Cleveland, Ohio.

POPS 'A Wrinkle in Time' author L'Engle dies I admired her and she shared her love of science with us. She was the first author of popular fiction to explain what she called the tesseract...the folding of space/time to travel. I will never forget the world where Meg and her friends travel where everyone does everything alike, even at the same time, no one would talk out to complaine, and all the houses looked exactly the same...eeriely prescient.
