Gravity Waves Support Big Bang Theory

Gravity waves support Big Bang theory after scientists at the South Pole Background Imaging of Cosmic Extragalactic Polarization (BICEP) detected a slight twisting of cosmic microwave radiation. This discovery lends credence to the theory of universal inflation, which was penned to explain the uniformity of temperature in the observable galaxies. The microwave energy that was observed is found throughout space and shows the universe as it was when it was just 380,000 years old and the average temperature was close to that of the surface of the sun.

The background radiation observed is a left over from the initial reaction that started the Big Bang and exploded the matter of the universe from the size of a subatomic particle to a grapefruit (relatively speaking) in the barest instant of a second. It was discovered that this radiation is polarized in 2002, meaning that it prefers to vibrate in one direction over the other. It was theorized that the gravity waves would have a squeezing and stretching effect on the space it traveled through, and this would cause visible changes in the pattern of the microwave radiation.

To find the Gravity Waves that support the Big Bang theory the BICEP array, essentially a giant superconducting thermometer, was used to measure the temperature variances across a broad swath of space. The differences were very small and very hard to detect, but the dry, thin air of the South Pole combined with the highly refined BICEP telescope were able to detect a faint swirling of the radiation. Previous study into the issue by the PLANCK space craft set the maximum amount of swirl of .11 which would have debunked many popular inflation theories before the race started, but the BICEP array was able to detect a swirl of .20 which was within the parameters set by the theory.

Confirming the presence of gravity waves explains the flaws in the Big Bang theory, chiefly the uniformity of our universe, and sheds light on how the all of the various energies work together to make things run the way they do, despite all of the seeming inconsistencies. It is thought that the Big Bang was originated in a manner similar to a glass of water being super cooled. Under the right conditions water will stay liquid below freezing temperatures until it is disturbed at which point it freezes very quickly and throws out the latent heat into the surrounding air. It is thought just before the moment of the Big Bang (excuse the idea of a moment before celestial time has begun) the matter of the universe was in a similar state, liquid despite its surroundings. Einstein theorized that the because of this state, space itself was imbued with a kind of energy that caused space to repel itself and expand. As the expansion went on more space was created, which pushed the reaction further and further until we reached the state of the universe as we know it.

This will be much harder to confirm however, as despite our ability to identify gravity waves to support the Big Bang theory, even our most specialized instruments will not be able to look back to before the Big Bang, as all energy from that period was altered or absorbed in the initial reaction.
