The December 8, 2011 Nature article ,Two ten-billion-solar-mass black holes at the centres of giant elliptical galaxies, by Nicholas J. McConnell et al :
"One key aspect to the early Universe is that the gas available to make stars did not have metals (which, to astronomers, mean every element except hydrogen and helium), since metals came later as a result of nuclear fusion in the stars themselves. This effectively made cooling of gas slow and...

Regarding the topic Is the universe expanding?, the ESA states:
1. "One of Hubble's initial 'core' purposes was to determine the rate of expansion of the Universe, known to astronomers as the "Hubble Constant". After eight years of Cepheid observations this work was concluded by finding...

The Big Bang disproved that we are at the center of the universe. :smile: The European Space Agency on July 5, 2010 had a article "Planck unveils the Universe – now and then" that I think is helpful to this discussion:
It's been a while since I read THE GRAND DESIGN by Stephen Hawking and Leonard Mlodinow. Please give me the page from the book that you are referencing in your statement. I'd like to review it. Thanks.:smile:
Orion1 deleted his/her contributions from this topic though I did quote (copy) Orion1 as noted in posts #296 and 297 prior to Orion1's action. Shame on you, Orion1! Beware people of Orion1's tricky nonsense. The person may do it again. You should know Orion1 that your message does appear...
Orion, I already answered the questions. You need to read again and attempt to understand what I have previously posted. Also, a theory doesn't deal with "ifs." You need to first understand what a theory means. There are no universes. Period. End of story.
"What is Beyond The Observable Universe?" is the topic. Science only deals with the observable. We have The Big Bang Theory. It is extremely important to know what a theory means. Also, the following definition of a *theory* applies to every other scientific theory. Everyone should know this...

Hi Jaebaeli, my previous statement was strictly about the fact that in Charles Darwin's lifetime he didn't write about cosmology though I am grateful for your contribution which allowed me the opportunity to bring forth to the public what the AAAS has to offer about Charles Darwin. I...
Hi jaebaeli. Nice to see you have joined PF. Darwin didn't write about cosmology. Here is a small section from a large document that hopefully helps you understand more about Darwin. The document is Benchmarks~ Online Project 2061~ AAAS (American Association for the Advancement of Science)
