Big+Bang


 * //The Big Bang Theory //**

 The Big Bang Theory is an effort to explain what happened at the very beginning of our universe. According to the standard theory, our universe started  its existence as "singularity" around 13.7 billion years ago. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of black holes. Black holes are areas of intense gravitational pressure. Our universe is thought to have begun VERY small, hot, and dense. Since it was so small and all the pressure from the black holes it all came together until it couldn’t anymore and than it started to slowly expand into the universe we have today, it’s thought that the universe is still expanding.

**//MISCONCEPTIONS: //**


 * Some Misconception are that, we tend to imagine a giant explosion, Experts however say that there was no explosion it just expanded.
 * Another misconception is that we tend to image the singularity as a little fireball appearing somewhere in space. According to the many experts however, space didn't exist prior to the Big Bang. [[image:bigbangMFL.jpg width="255" height="164" align="right"]]

 **//FACTS://**
 * //EVIDENCE FOR THEORY: //**
 * First of all, we are reasonably certain that the universe had a beginning.

 * <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; mso-fareast-font-family: 'Times New Roman';">Third, if the universe was initially very, very hot as the Big Bang suggests, we should be able to find some remnant of this heat.
 * <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; mso-fareast-font-family: 'Times New Roman';">Finally, the abundance of the "light elements" Hydrogen and Helium found in the observable universe are thought to support the Big Bang model.

 * The universe is 13.7 billion years old
 * All the matter in the universe used to be very close together (very dense)
 * The universe used to be a very uniform cloud of energy/mass despite it being very clumpy today (galaxies being those clumps)
 * Space began to expand and pushed matter apart
 * The expansion of space is accelerating
 * In the beginning the universe was so hot all the universal forces (gravitation, electromagnetism, etc.) were one force
 * The accelerating expansion of the universe will one day spread galaxies so far apart we will not be able to see them because the light leaving them will constantly have new space created in front of it.

We think that the big bang theory really existed.**
