Mysterious New 'Dark Flow' Discovered in Space. "As if the mysteries of dark matter and dark energy weren't vexing enough, another baffling cosmic puzzle has been discovered. Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can't be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon 'dark flow.' The stuff that's pulling this matter must be outside the observable universe, researchers conclude." [more inside]

Astronomers find a giant hole a billion light years across & located 8 billion light years away from us. They believe it could be evidence of another Universe at the edge of ours.

Remember CERN from The Da Vinci Code? And their mega-project the Large Hadron Collider(previously mentioned here?) This BBC Horizons show, The Six Billion Dollar Experiment, does a good job illustrating why such an experiment is so cool, important and fascinating. Apparently, the universe is finite.

As the Pentagon ousts plans to turn insects into cyber war machines you'd be forgiven for asking the question: Where does the real digital end and the faked life begin? Are we simulating life synthetically? or just speeding up an entirely natural process? Technologically engineered life is here to stay. Its not far fetched to speculate that simulacra may become all there is.

If the universe is a hologram and the healthy human brain a valve of consciousness then where'd this mental infinity come from? Are we simply living the simulacrum? Or does Pi protect us all, forever, infinitely?

Misconceptions about the Big Bang

Parallel universes Alternate universes may exist besides our own in some ghostly manner. Various science-fiction series explore parallel universes, but what do serious physicists think? Hugh Everett III's doctoral thesis outlines a controversial theory in which the universe at every instant branches into countless parallel worlds. Physicist Andrei Linde's theory of self-reproducing universes implies that new universes are being created all the time through a budding process. Stephen Hawking's quantum cosmology also suggests the possibility of other universes connected by wormholes. Some scientists feel that the famous photon double slit experiments proves the existence of parallel universes in which a photon from one universe interacts with a photon from another. Black hole theory suggests that black holes may be portals to parallel universes.
    Science-fiction stories about parallel universes always delight the mind. Two of my favorite SF novels on parallel universes are Heinlein's Job and Number of the Beast. Several others intrigue me, such as The Neoreality Series, Diaspora, and Parallelities. Science books on the subject include a famous book by David Deutsch.
    Do you have any favorite books on parallel universes or parallel realities, fiction or nonfiction? What do you think? No doubt, scientists and science-fiction authors will continue to explore the concept in the decades to come.

you know, you're right... it really does look like my morning coffee. but wait just a minute, didn't we say it was more of a blue-green Tidy-Bowl kind of hue? now i am all confused. good thing i didn't go through with that "paint my house the color of space" idea...

So you think the expansion of the universe is accelerating? Think again! (Contains links to full paper in .pdf etc.)

Stephen Wolfram: A New Kind of Science - From the publisher's summary, "Starting from a collection of simple computer experiments — illustrated in the book by striking computer graphics — Wolfram shows how their unexpected results force a whole new way of looking at the operation of our universe." May be big. Thoughts?

Black holes blow as well as suck. It's amazing what we find out about the universe. Imagine what we don't know?

The Big Re-run? "In the first millionth of a second after the universe’s beginning, the entire cosmos consisted of this ultradense, ultrahot brew, scientists say." And now scientists are trying to re-enact the Big Bang. Too big of a task to take on?
