Cosmic inflation: 'Spectacular' discovery hailed

RATE THIS! +35
Posted in Science on 17th Mar, 2014 11:27 PM by AlexMuller

Scientists say they have extraordinary new evidence to support a Big Bang Theory for the origin of the Universe. Researchers believe they have found the signal left in the sky by the super-rapid expansion of space that must have occurred just fractions of a second after everything came into being. It takes the form of a distinctive twist in the oldest light detectable with telescopes.

 
"This is spectacular," commented Prof Marc Kamionkowski, from Johns Hopkins University.
 
"I've seen the research; the arguments are persuasive, and the scientists involved are among the most careful and conservative people I know," he told BBC News.
 
The breakthrough was announced by an American team working on a project known as BICEP2. This has been using a telescope at the South Pole to make detailed observations of a small patch of sky.
 
The aim has been to try to find a residual marker for "inflation" - the idea that the cosmos experienced an exponential growth spurt in its first trillionth, of a trillionth of a trillionth of a second.

This is an outstanding observation and a great breakthrough in understanding the very beginning of the universe. This supports an important hypothesis and provides a bases to build on Reply

This is the case when the direct testing is possible: inflation came with a very specific prediction - that it would be associated with waves of gravitational energy, and that these ripples in the fabric of space would leave an indelible mark on the oldest light in the sky. So, one could try to observe this!

And scientists now identified this signal . As they state This is opening a window on what we believe to be a new regime of physics - the physics of what happened in the first unbelievably tiny fraction of a second in the Universe." Reply

What a great way to run the "movie" backwards. Everything must have been much closer together in the past and the earliest moments can now be grasped. Reply
