What is the Hubble Ultra Deep Field??
Adapted from Wikipedia:
The HUDF is the deepest image of the universe ever taken in visible light and it will be used to search for galaxies that existed between 400 and 800 million years after the Big Bang (Redshifts between 7 and 12). The star near the center of the field is USNO-A2.0 0600-01400432 with apparent magnitude of 18.95.
The field imaged by the ACS contains over 10,000 objects, the majority of which are galaxies, many at redshifts greater than 3, and some that probably have redshifts between 6 and 7. The NICMOS measurements may have discovered galaxies at redshifts up to 12.Click Here for a detailed image of the Ultra Deep Field
In other words, the scientists are close in finding what actually happen before and during the "Big Bang", a theory that states the formation of our universe...(That's what they claimed...not me...)
There are infinite possibilities of what might occur before the Big Bang, such as the M-Theory (Membrane Colision that creates the Big Bang theorem..I am no cosmology here...Google for more information of these terms..Nothing....Big Ball...Pangu (Chinese Myths), Aliens....etc
Maybe some day we'll see God on the other end creating the universe...who knows?
