ERIS: World's first realistic simulation of the formation of the Milky Way

Isn’t there supposedly a black hole at the center of the Milky Way and if so, did it or did it not figure in the formation of the galaxy? Or any spiral galaxy.

Yup. There is, in fact, a supermassivie black hole at the center of this and every other galaxy that is observable. It has been proven by measuring the speed of the orbit of stars near the center of each galaxy - the stars whip around something invisible at blinding speed and sometimes lose streams of material to the black hole. If you watch how fast the middle dot is spinning in the video, I believe they did use the black hole in their equations.

Fascinating stuff.

Well...this brings up a fascinating 'chicken or the egg' question as relates to the video and the timeline they propose.

Bringing Order out of Chaos would seem to violate the Second Law of Thermodynamics -- unless there is an Organizing Principle outside the system. I do not see Discordianism as a serious thing at all. But I see an organized Universe, and I know that God exists. And I see a project called ERIS showing how the Milky Way became organized and I see science showing me that God exists.

It's just physics. Sheesh. Lighten up. Gravity just works. No deities required. No thermodynamic laws are broken by some matter being drawn toward other matter and going into orbit.

Yeah, but if I had to guess, I would say that the BH forms early on and creates a huge gravity well which then causes more matter to be drawn into the area, whch then creates an even bigger gravity well - so on and so on... A small cluster of stars with one really big one that collapses and becomes a BH can then become an even larger gravity well that draws in more and more stars as the eons pass.

Very cool!!!!!

Zurich, huh. Makes sense that they’d present it as a clockwork.

Funny response to the YouTube video: “Can we see it in real time?”

[TheOldLady]

Very nice, Joe.

[Bloody Sam Roberts]

That was my thought as well. It would take a massive gravity well or singularity to initiate the clumping of matter from such huge distances. More than could be expected in a more spontaneous and black hole-less event. And since there were plenty of stars at that time anyway, I imagine there were a goodly number of black holes or even neutron stars around after many a hot, fast burning star collapsed.

God, I wish I had access to his wardrobe hand me downs.

I didn’t see anything referencing this article at the link?

It looks more like an advertisement for an Internet book store. Isn’t posting advertisements on FR frowned upon?
