“Waysis.”

shouldn’t that be “Milky Waysist.”

Just a ping for keeping up on the latest in astrophysics. Interesting stuff.

First “they” come for the dark matter. And then “they” come for the rest of us.

[only1percent]

Didn’t they come up with the theories of “dark” energy and matter in order to fudge the calculations that disproved some pet creation theory, like the Big Bang?

No. Astrophysicists observed some time ago that the rotation and certain other behavior of galaxies seemed to require the galaxies have more, and more smoothly distributed, mass than was accounted for by their stars (the non-dark, or baryonic, matter). In other words, galaxies spun more like they were solid discs rather than collections of stars separated by light years from one other.

This phenomenon would require some explanation regardless of the origin of the present universe. Red shift and other evidence of expansion continues to support the Big Bang theory notwithstanding other phenomena as of yet not explained.

Buddy of mine and I were just talking about this over the weekend. We are amateur astronomers, and were out observing. I was looking at NGC 2419, a Globular Custer that is so far away that it might just not be part of our galaxy at all, but, just floating between the galaxies in the local group. We postulated that if the universe has an abundance of these clusters, many very small (NGC 2419 is fairly bright, but, is larger that many of the custers around the milky way) then the universe could be fairly full of these things and we wouldn’t know it.

Photographs show that most galaxies have an abundance of globular clusters ‘halo’ed around them. No reason to suspect that there aren’t more free floating.

Just speculating!

I think a globular cluster is a proto-galaxy trying to organize itself......................

"I recommend the book “Privileged Planet”.

I recommend the DVD of the same title. This one, and "Star of Bethlehem" make a wonderful set for gift giving.

[MrB]

The DVD is good. Of course the book had a lot more examples and details of each example.

The DVD would have been 5 hours long if they included it all.

[redhead]

oooh, sweet!

Man plans, God laughs.

I hate DWTS.
My wife loves it for some reason..........

Thanks Ernest for the link, thanks Red Badger for the topic.
