Faith, the Universe, and Wisdom

Image
I think the universe is billions, not thousands, of years old; Earth isn't flat; Adam and Eve aren't German; poetry isn't science; and thinking is not a sin. If you've been reading my posts, you know why being a Christian doesn't interfere with my interest in science. Feel free to skip the rest of this post. It's mostly about reading the Bible, the universe, and getting a grip. I'll be back next Friday, 1 most likely talking about Proxima Centauri b , a planet orbiting the next star over from ours: in Proxima's habitable zone. More at A Catholic Citizen in America .

Starshot, SETI, and the Universe

Image
We may be within a generation of sending probes on flyby missions to other stars, high-energy jets from several distant galaxies all point in the same direction, and we're learning more about hot super-earths. That sort of thing fascinates me, your experience may vary. Meanwhile, SETI researchers will be checking out red dwarfs: which may be more promising places to look for neighbors than we thought.

Neutrinos and a Fading Universe

Image
We knew this universe was fading, but now scientists have a much clearer picture of how fast the lights are going out.... ...Other scientists are pretty sure they're detecting neutrinos generated inside Earth. "Pretty sure" isn't "really sure," though, so they're still working on that research.... ...Right after a very quick glance at natural philosophy becoming science, I'm going to say why I do not believe that thinking is a sin — again. You've probably read that sort of thing on this blog before, so skip ahead to Portrait of a Fading Universe , teach yourself origami, read a good book, whatever....

The Universe: a Magnificent Tent

Image
Folks have looked up and been impressed for a long time: " 1 Think! The heavens, even the highest heavens, belong to the LORD, your God, as well as the earth and everything on it. " ( Deuteronomy 10:14 ) " The heavens declare the glory of God; the sky proclaims its builder's craft. " ( Psalms 19:2 ) That galaxy is M31, the Andromeda Galaxy . Back when I was in high school, a fair number of books I read called it the "Great Andromeda Nebula." More up-to-date books occasionally called it an "island universe."

Large Hadron Collider: There’s More to Learn

Image
The world's largest and most powerful particle collider , CERN's Large Hadron Collider (LHC), is back in operation. Scientists will be studying conditions like those just after this universe began: at about twice the energies they used back in 2013. I'm excited at the prospect of learning more about the workings of matter and energy: and news about the LHC is already starting to get goofy. More at A Catholic Citizen in America .

Humility, Science, and Accepting Reality

Image
I could be a Christian, following my Lord, if I believed that we live on a flat plate with nothing between us and the cosmic ocean but a sold dome that holds the stars. But my faith doesn't depend on maintaining ignorance of what we've learned in the last two dozen or so centuries. Imagery in 1 Samuel 2:8 and Psalms 148:4 is beautiful, poetic, and consistent with Mesopotamian cosmology : hardly surprising, considering where the Hebrews lived. That was then, this is now, and we've learned quite a bit about the universe since the days of Kubaba and Enmerkar . Some details of their lives seem exaggerated, but folks still pad their resumes, and that — isn't another topic.... More at A Catholic Citizen in America .

Schrodinger's Cat(s); and Gravitational Waves, Revisited

Image
Quantum mechanics makes more sense if the Many-worlds interpretation of quantum mechanics is right, and we're still not sure whether BICEP 2 detected gravitational waves: or polarized dust. If you've been here before, and know why I don't see a conflict between science and faith, feel free to skip straight to "Who Killed Schrodinger's Cat?" (No animals were harmed in the writing of this post) ... ...Since I'm a Catholic, I believe that God created, and is creating everything. Since I also believe that God isn't a liar, and that truth cannot contradict truth: honest research cannot hurt faith. (Catechism of the Catholic Church, 144 , 159 )...

Scientific Discoveries: an Invitation to "Even Greater Admiration"

Image
This universe has been around for about 13,798,000,000 years, give or take 37,000,000. That's the current best estimate, from 2013 . It's big, too. The photo shows part of the Hercules Cluster of galaxies. Light from that bunch of galaxies traveled for about 500,000,000 years before reaching us. What we see is the Hercules Cluster as it was around the middle of the Cambrian here, roughly when the first trilobite showed up. Taking the universe 'as is' makes sense: for me, anyway. I would much rather learn more about this wonder-filled creation, than insist that the Almighty is limited to what folks knew a few centuries back. More at A Catholic Citizen in America .

Science, Faith, and Leaving the 19th Century Behind

Image
(From Peter Kennett, via Wikimedia Commons, used w/o permission.) (M31, the Great Andromeda Galaxy, one of 54 galaxies in the Local Group , photographed in 2005.) Folks can see the Andromeda Galaxy from Earth's northern hemisphere: on a clear night with no moon, anyway. Abd al-Rahman al-Sufi gets credit for 'discovering' it: but I'm pretty sure that quite a few folks had seen it before he mentioned "A Little Cloud" in " Book of Fixed Stars, " somewhere around 964. Knowledge and Change In 1764, Charles Messier, another astronomer, put the galaxy in his catalog as a nebula: object M31. By the 19th century, astronomers realized that some light from the Andromeda "nebula" resembled light from stars. In 1925, Edwin Hubble used observations of Cepheid variable stars to demonstrate that the Andromeda Galaxy was another " island universe :" far outside our Milky Way Galaxy. Light from the Andromeda Galaxy passing Earth toda

Jadeite from Space; a Moon of Mars; and Kepler's New Mission

Image
A century ago, we didn't realize that mountains fall from the sky at irregular intervals. A century from now, we'll probably be mining asteroids. Today, we're learning that there's much more to learn.... ...Knowledge and Dominion (From ESA/Hubble, via Wikimedia Commons, used w/o permission.) " Today I would like to highlight another gift of the Holy Spirit: the gift of knowledge . When we speak of knowledge, we immediately think of man's capacity to learn more and more about the reality that surrounds him and to discover the laws that regulate nature and the universe. The knowledge that comes from the Holy Spirit, however, is not limited to human knowledge; it is a special gift, which leads us to grasp, through creation, the greatness and love of God and his profound relationship with every creature.... " (Pope Francis, General Audience . (May 21, 2014)) We live in a beautiful, good, ordered universe: surrounded by wonders which had remained unkn
