A Universe From Nothing (Lecture)

Via (topdocumentaryfilms.com):

Lawrence Krauss gives a talk on our current picture of the universe, how it will end, and how it could have come from nothing.

Krauss is the author of many bestselling books on Physics and Cosmology, including “The Physics of Star Trek.”

If you’ve ever wanted to answer that annoying question, “how could the Universe have formed from nothing”, then watch this video.

Lawrence Krauss is funny, informative, and if you watch the entire video (it’s over an hour long, so you might need to pause it a few times), he will blow your mind. Lawrence seems like a pretty cool guy.

This is an absolutely AMAZING lecture given by such a brilliant physicist living among us. Presented by Richard Dawkins, Lawrence Krauss is deemed the “Woody Allen” of physics & this lecture carries monumental information about the history of everything, the complexity & sophistication of the universe we currently exist in, the different universes that must exist, the end of our universe & other universes throughout present/future space & time, there being unequivocally no need to turn away from this reality & substitute it with God or a deity, the importance & incredibly humble virtue it is to be living at the age of space & time we are at right now, and above all, that we are of very little insignificance when understanding the cosmic perspective of life.

‘Jaw-Dropping!’ Crab Nebula’s Powerful Beams Shock Astronomers

When astronomers detected intense radiation pumping out of the Crab Nebula, one of the most studied objects in space, at higher energies than anyone thought possible, they were nothing short of stunned.

The inexplicably powerful gamma-rays came from the very heart of the Crab Nebula, where an extreme object called a pulsar resides.

“It was totally not expected — it was absolutely jaw-dropping,” Andrew McCann, a Ph.D. candidate at McGill University in Montreal, Canada, and a co-author of the new study, told SPACE.com. “This is one of the hottest targets in the sky, so people have been looking at the Crab Nebula for a long time. Now there’s a twist in the tale. High-energy rays coming from the nebula are well-known, but coming from the pulsar is something nobody expected.”

Eye-Popping Look Into Space

More than 9,000 light-years away from Earth, stars form within the star cluster NGC 281, colloquially known as the “Pacman Nebula.” The nebula gets its name because optical images show dust obscuring some of the nebula’s glowing gas in a shape reminiscent of the arcade character. This infared image shows that dust glowing brightly instead.
