Furthermore, these experiments often produce such copious amounts of data that hundreds or thousands of researchers are needed to analyze the results, often with the aid of computers, clusters of computers or supercomputers. But that does not mean there are no great mysteries left to solve or that earth-shattering discoveries like the CMB finding are relics of history. Clara Moskowitz is Scientific American 's senior editor covering space and physics. She has a bachelor's degree in astronomy and physics from Wesleyan University and a graduate degree in science journalism from the University of California, Santa Cruz.

This light, left over from shortly after the big bang, pervades the universe and carries a record of the first epoch after the birth of the cosmos The instrument was designated as a National Historic Landmark in for its role in the significant finding, which opened the gateway to modern cosmology This configuration allows it to make sensitive measurements of far-off objects without interference from background radiation Get smart.

Rather than imagining a balloon popping and releasing its contents, imagine a balloon expanding: an infinitesimally small balloon expanding to the size of our current universe. 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. Back in the late '60s and early '70s, when men first walked upon the moon, "three British astrophysicists, Steven Hawking, George Ellis, and Roger Penrose turned their attention to the Theory of Relativity and its implications regarding our notions of time. In and , they published papers in which they extended Einstein's Theory of General Relativity to include measurements of time and space. Prior to the singularity, nothing existed, not space, time, matter, or energy - nothing.

So where and in what did the singularity appear if not in space?

We don't know where it came from, why it's here, or even where it is. All we really know is that we are inside of it and at one time it didn't exist and neither did we. First of all, we are reasonably certain that the universe had a beginning. Second, galaxies appear to be moving away from us at speeds proportional to their distance.

This is called "Hubble's Law," named after Edwin Hubble who discovered this phenomenon in This observation supports the expansion of the universe and suggests that the universe was once compacted. 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. This is thought to be the remnant which scientists were looking for.

Penzias and Wilson shared in the Nobel Prize for Physics for their discovery. Finally, the abundance of the "light elements" Hydrogen and Helium found in the observable universe are thought to support the Big Bang model of origins. Is the standard Big Bang theory the only model consistent with these evidences? No, it's just the most popular one.

Internationally renown Astrophysicist George F. Ellis explains: "People need to be aware that there is a range of models that could explain the observations…. For instance, I can construct you a spherically symmetrical universe with Earth at its center, and you cannot disprove it based on observations….

Can We Find Out Where The Big Bang Started?

You can only exclude it on philosophical grounds. In my view there is absolutely nothing wrong in that. What I want to bring into the open is the fact that we are using philosophical criteria in choosing our models.

A lot of cosmology tries to hide that. Gentry claims that the standard Big Bang model is founded upon a faulty paradigm the Friedmann-lemaitre expanding-spacetime paradigm which he claims is inconsistent with the empirical data.

He chooses instead to base his model on Einstein's static-spacetime paradigm which he claims is the "genuine cosmic Rosetta. Any discussion of the Big Bang theory would be incomplete without asking the question, what about God? This is because cosmogony the study of the origin of the universe is an area where science and theology meet. Creation was a supernatural event.
