A Universe In Which Time Has No Beginning

"Maybe the Big Bang never happened because the universe never began because it has always existed." Scientific American magazine revisits the decade-old idea that we live in a "Rainbow" universe (where different wavelengths of light experience spacetime differently and where the big bang may never have happened) following the publication of new physics research on the subject.

Quantum Graphity

The start of the Universe should be modeled not as a Big Bang but more like water freezing into ice, according to a team of theoretical physicists at the University of Melbourne and RMIT University. Results published this month in Physical Review D (abstract) (via ABC Science). [more inside]

Dark Flow

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]

The Universe is Finite

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.

The Big Hum

The sound of the Universe being born. University of Washington professor calculates the frequencies of sound waves propagating through the Universe during its first 760,000 years by analyzing small differences in sky temperature. More information here and here.

What we need more of is science.

The PHENIX (Pioneering High Energy Nuclear Interaction eXperiment) collaboration hopes to study a new state of matter, the quark-gluon plasma, which they think was present in the first microseconds after the Big Bang. And they have games!

The oldest light in the cosmos

BAM! The Microwave Anisotropy Probe's long-awaited map of the afterglow of the big bang was released today, and all of a sudden, most of the uncertainty in the concordance model of cosmology has disappeared. We now know, to within 1%, that the universe is 13.7 billion years old. We now know that Hubble constant is 71, plus or minus 4. And though the results agreed stunningly well with the weird picture that cosmologists have about the nature of the cosmos, there was one surprise -- the first stars were born way before expected. Great day for science, and a likely future Nobel.

Oh sure, once again, this "theory" proves nothing. Nothing more than another failed attempt to dismiss God's work. When are these morons, with such an imagination, ever going to admit it, that their theory is nothing more than that. I could ramble on and on like these suppose "scientists" about nothing, and make all these supposed "patterns", milarky, lies, and made up falsehoods on how the universe was just made from some wild explosion. Oh sure, that is how it was made.....just some big bang, then the next thing you know, man walked out of the swamp, got in his Mercedes, and drove away....haha Just keep on believing such crap about this big bang "theory". But just like before, this will fail again and prove that God did create the world, and he has been, is, and always will be the creator, not the "big banger". And that is a FACT, not a "theory".....

The Big Re-run?

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?
