What Is the Big Bang Theory?... by SkY2k 2015/11/27 23:39
Many People Have Their Own Ideas On How The Universe Was Created...Well After I Watched A Documentary Called The Big Bang Theory, I Would Like To Share To You What Iv Learnt In A Scientific Way Of The Creation Of The Universe...

The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it talks about the universe as we know it starting with a small singularity, then inflating over the next 13.8 billion years to the cosmos that we know today.
Because current instruments don't allow astronomers to peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical theory and models. Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background...

The First Second, And The Birth Of Light...

In the first second after the universe began, the surrounding temperature was about 10 billion degrees Fahrenheit (5.5 billion Celsius),according to NASA. The cosmos contained a vast array of fundamental particles such as neutrons, electrons and protons. These decayed or combined as the universe got cooler.
This early soup would have been impossible to look at, because light could not carry inside of it. "The free electrons would have caused light (photons) to scatter the way sunlight scatters from the water droplets in clouds," NASA stated. Over time, however, the free electrons met up with nuclei and created neutral atoms. This allowed light to shine through about 380,000 years after the Big Bang.
This early light sometimes called the "afterglow" of the Big Bang is more properly known as the cosmic microwave background (CM/smiley. It was first predicted by Ralph Alpher and other scientists in 1948, but was found only by accident almost 20 years later...

Arno Penzias and Robert Wilson, both of Bell Telephone Laboratories in Murray Hill, New Jersey, were building a radio receiver in 1965 and picking up higher-than-expected temperatures,according to NASA. At first, they thought the anomaly was due to pigeons and their dung, but even after cleaning up the mess andkilling pigeons that tried to roost inside the antenna, the anomaly persisted.
Simultaneously, a Princeton University team (led by Robert Dicke) was trying to find evidence of the CMB, and realized that Penzias and Wilson had stumbled upon it. The teams each published papers in the Astrophysical Journal in 1965...

Determining the age of the universe...

The cosmic microwave background has been observed on many missions. One of the most famous space-faring missions was NASA's Cosmic Background Explorer (COBE) satellite, which mapped the sky in the 1990s.
Several other missions have followed in COBE's footsteps, such as the BOOMERanG experiment (Balloon Observations of Millimetric Extragalactic Radiation and Geophysics), NASA's Wilkinson Microwave Anisotropy Probe (WMAP) and the European Space Agency's Planck satellite.
Planck's observations, released in 2013, mapped the background in unprecedented detail and revealed that the universe was older than previously thought: 13.82 billion years old, rather than 13.7 billion years old...

Gravitational Wave Controversy...

While astronomers could see the universe's beginnings, they've also been seeking out proof of its rapid inflation. Theory says that in the first second after the universe was born, our cosmos ballooned faster than thespeed of light. That, by the way, does not violate Albert Einstein's speed limit since he said that light is the maximum anything can travel within the universe. That did not apply to the inflation of the universe itself.
In 2014, astronomers said they had found evidence in the CMB concerning "B-modes," a sort ofpolarization generated as the universe got bigger and created gravitational waves. The team spotted evidence of this using an Antarctic telescope called "Background Imaging of Cosmic Extragalactic Polarization", or BICEP2.
"We're very confident that the signal that we're seeing is real, and it's on the sky," lead researcher John Kovac, of the Harvard-Smithsonian Center for Astrophysics, told Space.com in March 2014.
But by June, the same team said that their findings could have been altered by galactic dust getting in the way of their field of view.
"The basic takeaway has not changed; we have high confidence in our results," Kovac said in apress conference reported by the New York Times. "New information from Planck makes it look like pre-Planckian predictions of dust were too low," he added.
The results from Planck were put online in pre-published form in September. By January 2015, researchers from both teams working together "confirmed that the Bicep signal was mostly, if not all, stardust,"the New York Times said in another article...

Faster inflation, multiverses and charting the start...

The universe is not only expanding, butgetting faster as it inflates. This means that with time, nobody will be able to spot other galaxies from Earth, or any other vantage point within our galaxy.
"We will see distant galaxies moving away from us, but their speed is increasing with time," Harvard University astronomer Avi Loeb said in a March 2014 Space.com article.
"So, if you wait long enough, eventually, a distant galaxy will reach the speed of light. What that means is that even light won't be able to bridge the gap that's being opened between that galaxy and us. There's no way for extraterrestrials on that galaxy to communicate with us, to send any signals that will reach us, once their galaxy is moving faster than light relative to us."
Some physicists also suggest that the universe we experience is just one of many. In the "multiverse" model, different universes would coexist with each other like bubbles lying side by side. The theory suggests that in that first big push of inflation,different parts of space-time grew at different rates. This could have carved off different sections different universes with potentially different laws of physics.
"It's hard to build models of inflation that don't lead to a multiverse," Alan Guth, a theoretical physicist at the Massachusetts Institute of Technology, said during a news conference in March 2014 concerning the gravitational waves discovery. (Guth is not affiliated with that study.)
"It's not impossible, so I think there's still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [the idea of a] multiverse seriously."
While we can understand how the universe we see came to be, it's possible that the Big Bang was not the first inflationary period the universe experienced. Some scientists believe we live in a cosmos that goes through regular cycles of inflation and deflation, and that we just happen to be living in one of these phases...

With All Due Respect As I Stated In The Beginning Of This Post,Each Religion Believes On Their Own Aspects On How The Universe Was Created, So Don't Get Me Wrong Because This Is Just A Scientific Explanation /smiley

Expanding Earth theory evidence or articles, posts, discussions, videos and reports that are positive or at least consider the idea as an interesting proposal and and not on a witch hunt about the Growing Earth theory.

Oceanic crust underlies most of
the two-thirds of the Earths
surface which is covered by the
oceans. It has a remarkably
uniform composition (mostly
49% 2% SiO2) and thickness
(mostly 7 1 km).

The ocean floor is the most
dynamic part of the Earths
surface. As a result, no part of
the oceanic crust existing today
is more than 200 million years
old, which is less than 5% of
the age of the Earth itself.

New oceanic crust is constantly
being generated from the
upper mantle by sea-floor
spreading at mid-ocean ridges,
while other parts of the
oceanic crust are being recycled
back into the mantle at
subduction zones.
