dark matter blob confounds experts
This composite image shows the distribution of dark matter, galaxies, and hot gas in the core of the merging galaxy cluster Abell 520, formed from a violent collision of massive galaxy clusters. Starlight from galaxies is indicated in orange. Green indicates hot gas, and blue indicates mass, most of which is dark matter.
From an article by Alan Boyle on CosmicLog… I love finding examples that remind us that there’s so much more to “this world” than we may see with our eyes or hear with our ears…
“…Studies have shown that we can see only about 15 percent of the matter in the universe. Most of the matter that exists around us can’t be seen directly, but can be detected only by its gravitational effect. Scientists don’t know what dark matter is, but they suspect it’s an exotic class of subatomic particles that can interact only weakly with the kinds of matter we can see.”

Ha!
I love coming across something small, clean and neat that tweaks my curiosity, waters my imagination!
I watched a video of a presentation about scientists leaving Hubble on a point of “nothing” for 10 minutes. Some scientists got their knickers in a knot over such a waste of valuable time. Turns out, Hubble did it’s work of wonder and opened a whole raft of new universes! Yeay! I love mankind being shown how we simply are not all that gloriously all-knowing!
Wow, Amy, that’s so wonderful, I want to see/read that story! I’ve experienced some very powerful instances lately, of miracles peeking out through the cracks between the big chunks (the chunks where we tend to look for them!)… Life is truly magical. Wishing you a week filled with wondrous surprises! Love & light, Leslee
