Scientists find cosmic ripples from birth of universe

Scientists find cosmic ripples from birth of universe

Published March 17, 2014


Astronomers have discovered what they believe is the first direct evidence of the astonishing expansion of the universe in the instant following the Big Bang -- the scientific explanation for the birth of the universe some 13.8 billion years ago.

Scientists believe that the universe exploded from a tiny speck and hurled itself out in all directions in the fraction of a second that followed, beginning just 10 to the minus 35 seconds (roughly one trillionth of a trillionth of a trillionth of a second) after the universe's birth. Matter ultimately coalesced hundreds of millions of years later into planets, stars, and ultimately us.

And like ripples from a ball kicked into a pond, that Big Bang-fueled expansion caused ripples in the ancient light from that event, light which remains imprinted in the skies in a leftover glow called the cosmic microwave background.

Scientists still don’t know who kicked the ball.

But if confirmed, the newfound ripples would be amazing proof of what has long been mere theory about what happened in those first millionths of a second.

“The implications for this detection stagger the mind,” said Jamie Bock, professor of physics at Caltech, laboratory senior research scientist at the Jet Propulsion Laboratory (JPL) and project co-leader. “We are measuring a signal that comes from the dawn of time.”

"It would be the most important discovery since the discovery, I think, that the expansion of the universe is accelerating," Harvard astronomer Avi Loeb, who is not a member of the study team, told Space.com. He compared the finding to a 1998 observation that opened the window on mysterious dark energy and won three researchers the 2011 Nobel Prize in physics.

The groundbreaking results came from observations by BICEP2, a telescope at the South Pole, of the cosmic microwave background -- a faint glow left over from the Big Bang.

Beginning a fraction of a fraction of a second after the universe's birth, according to the current theory, space-time expanded incredibly rapidly, ballooning outward faster than the speed of light. The afterglow from that expansion is called the cosmic microwave background, and tiny fluctuations in it provide clues to conditions in the early universe.

For example, small differences in temperature across the sky show where parts of the universe were denser, eventually condensing into galaxies and galactic clusters.

Since the cosmic microwave background is a form of light, it exhibits all the properties of light, including polarization. On Earth, sunlight is scattered by the atmosphere and becomes polarized, which is why polarized sunglasses help reduce glare. In space, the cosmic microwave background was scattered by atoms and electrons and became polarized too.

“Our team hunted for a special type of polarization called ‘B-modes,’ which represents a twisting or ‘curl’ pattern in the polarized orientations of the ancient light,” said Bock.

The team presented their work at a press conference Monda at Harvard -- the discovery of that characteristic pattern of polarization in the skies, which they called proof of the gravitational waves across the primordial sky.

“This work offers new insights into some of our most basic questions: Why do we exist? How did the universe begin? These results are not only a smoking gun for inflation, they also tell us when inflation took place and how powerful the process was,” Harvard theorist Avi Loeb said.

Bubble Universes

In addition to the multiple universes created by infinitely extending space-time, other universes could arise from a theory called "eternal inflation." Inflation is the notion that the universe expanded rapidly after the Big Bang, in effect inflating like a balloon. Eternal inflation, first proposed by Tufts University cosmologist Alexander Vilenkin, suggests that some pockets of space stop inflating, while other regions continue to inflate, thus giving rise to many isolated "bubble universes."

Thus, our own universe, where inflation has ended, allowing stars and galaxies to form, is but a small bubble in a vast sea of space, some of which is still inflating, that contains many other bubbles like ours. And in some of these bubble universes, the laws of physics and fundamental constants might be different than in ours, making some universes strange places indeed.

It's pretty mind boggling, isn't it?

Absolutely. It's mans greatest achievements that we have come to discover things so vastly far away and those so vastly small as well. I can't imagine anything more interesting or awe inspiring. I saw a quasar 10 billion light years away. Thats

6,000,000,000,000,000,000,000,000,000,000 miles away. Thats impressive in my book.

Lawrence Krauss has answers to that.

"Krauss's latest book, A Universe from Nothing: Why There is Something Rather than Nothing, explains the scientific advances that provide insight into how the universe formed. Krauss tackles the age-old assumption that something cannot arise from nothing by arguing that not only can something arise from nothing, but something will always arise from nothing."

Oh and to continue being devils advocate (although I'm being dismissed). If the answer is just because I believe it; to both the religion and the universe, maybe natural sciences formed from nothing without design and by accident is just as hard to comprehend as a little invisible guy in the sky.


Perhaps, the eternal universe is the eternal being, both "super natural" and "natural science" joined together and explained by two opposite sides of our human comprehension.

I would also like to point out I'm playing devils advocate on this, not trying to convince anyone the existance or non-existance of anything.

But when you rally simplify the entire arguement, science says creation happened basically by chance; while religion points more toward a designed /planned event. As far as I know it could be either. The Big Bang theory could have just been a random gas explosion, or a designed gas explosion. the findings mentioned in the OP are not proving / denying the nature to the primal question, "why".
No, Science does not say the universe happened by chance. Science says that we don't have enough information to know how the universe came to be. It's not an "either religion or science" choice regarding the beginning of the universe. The Big Bang theory doesn't actually address the creation of the universe. Because science currently doesn't have the technology to find any evidence of what happened before the universe began expanding. The Big Bang theory only addresses the time frame of several seconds after the universe was the size of a marble, to present time when the universe is measured to be 13 billion light years wide. It makes no claims of what might have happened before the universe began expanding.

The Big Bang(if true) wasn't simply a big explosion. There is no confusing the Big Bang with a random gas explosion. Before that point, there wasn't even empty space.

The findings in the OP were never meant to explain the "Why". The findings were meant to show that one of the major predictions for evidence of the Big Bang has actually been verified, giving more validity to the Big Bang theory as a whole.
