PremiumVIVAnews -Whether the universe had a definite or indefinite size? Concerning the size of the universe which can be seen increasingly widespread, is the farthest object that could be seen to be much older than that estimated that about 14 billion years.
Known, photon on the cosmic microwave background has been a time of 45 billion a year to arrive on Earth. That means, of the universe seen by the eye at least has a size of 90 billion light years.
However, it turns out that the universe is much more widely. This can be known thanks to the statistical analysis made by Mihran Vardanyan and colleagues, researchers from the University of Oxford.
According to Vardanyan, as quoted from Daily Galaxy, Wednesday 4 May 2011, the key from knowing the actual size of the universe is by measuring lengkungannya.
Previously, astronomers have several methods to measure the curvature. One of them, according to Technology Review from the Massachusetts Institute of Technology, is using the objects in the distance already known size and compare with how great she looks.
If the object it looks bigger than it should, the universe is closed. If it looks just as it should, the universe is flat. However, if smaller, meaning the universe open (infinity).
The problem is, when scientists observed data of various models, they get a different answer to find out the answer for sure around the arch and the size of the universe. Then, where the most accurate of whom?
Breakthrough taken Vardanyan and his team are known by the name of the model averagingcall Bayesian Networks. The technique is more intelligent than by using measurement of curvature commonly used by scientists to describe the data they have.
According to the modeling made Vardanyan, the curvature of the universe is very close to 0. In other words, most likely, the universe is flat.
A universe is flat can also be infinite. And calculations made by Vardanyan was also consistent with this. From the calculation, the universe has a size of at least 250 times larger than the volume measuring Hubber 13.8 billion light years. (art)
