The Boom in Galaxies After the Big Bang

More proof that the Universe is continually expanding at an increasingly accelerated rate. Why resist change, growth and transformation when its the natural state of everything!

The Boom in Galaxies After the Big Bang: "Two independent teams of astronomers are reporting that they might be zeroing in on the time that bright galaxies began to light up the primordial universe."

The number of galaxies, they say in two papers published today in Nature, seems to have sharply increased 700 million to 900 million years after the Big Bang. If true, the results could be a boon to theorists who would like to understand how galaxies formed and what stars they were made of.

The results also lend support to the prevailing notion of galaxy formation. That theory holds that luminous galaxies were rare in early times and that they grew from the assembly of smaller building blocks.

Astronomers compute the distances of cosmic objects in space and time by measuring how much their light has been lengthened in wavelength, or “red shifted,” by their motion away from Earth because of the expansion of the universe.
