Massive Monsters Mash Models (of universe evolution)

A net friend alerted me to the article “Galactic Monster Mystery Revealed in Ancient Universe” (Nov. 19, 2015, by Ian O’Neill). The “monsters” involved are massive galaxies. There are lots of massive galaxies in the universe. What makes these such monstrous mysteries is that they are very far away, and (given the time it would take light to travel so far) we’re seeing them as they were (or would have been) billions of years ago, so long ago that the earliest are said to be at the stage when the universe was just one billion years old: “This selection of massive galaxies all seem to have formed no earlier than around 1 billion years after the Big Bang;” Continue reading Massive Monsters Mash Models (of universe evolution)

NPR admits existence is a mystery

All too often, scientists and others give the impression that we know very nearly all the answers to the major questions, and there’s little left except filling in the details. This was a widespread attitude in the late 1800s, too, about the same time that Darwin’s theory became widely adopted. Soon after, physical science took some strange new turns, with Einstein’s General and Special theories of relativity and quantum mechanics. Our “knowledge” of the solar system and universe has increased and undergone some alterations, too. There are still a lot of major mysteries and unresolved discrepancies, so it is very strange that some people seem to think that “Science” has pretty much figured out everything and left no room for the supernatural and religion.

So I found it refreshing to see an article on the NPR website that points out that “There was a big bang and the universe appeared and that’s how we got here” isn’t really settled and the end of the story.  Continue reading NPR admits existence is a mystery

Black Holes, Gravity Waves, and Unending Gaps

First, two news stories.

First up: “Black hole is 30 times bigger than expected” By Amanda Barnett, CNN, Updated 8:04 PM ET, Sat September 26, 2015

“This shouldn’t be possible. Researchers say they’ve detected a supermassive black hole at the center of a newly found galaxy that’s far bigger than current theories allow.” As the title indicates, specifically it’s about 30 times larger than a galaxy the size of the one it’s in should be able to form. Wow.  Not much else to say about it; if you want the details, click on the title to go to the article. As to how this surprise came about, the scientists can only guess: “…it could be that the black hole just grew much faster than the galaxy surrounding it, or maybe the galaxy’s growth was prematurely stopped.” Why or how the black hole would or could grow fast, or what would or could stop the galaxy’s growth, they don’t say.
