Re: APOD: Active Galaxy NGC 1275 (2023 Jan 26)

Considering the similarities between the cosmic web and our neuronal network , it seems likely there is some corollary. If a 4th dimension is defined as every point in the 3rd dimension having accessibility anywhere within the fourth, there is an eerie similarity to quantum entanglement . Perhaps th...

The "How To" create a space image seems a lot easier than getting there. Plenty goes into the process but anyone can imagine their way into space. :yes:

Re: APOD: Galaxy Wars: M81 and M82 (2023 Jan 20)

Are density waves a proven theory ? To me, they sound as nebulous as dark matter. :? There is no such thing as a proven theory. They cannot ever be proven, only disproven. Density wave theory is very widely accepted because it is modellable and the output of the models closely match observation. Th...

Re: APOD: NGC 2264: The Cone Nebula (2023 Jan 10)

My first thoughts revolved around how many stars and planets does an area of the size and density of the Cone Nebula represent? The nebular hypothesis speaks to the process why these clouds form components, and are essential in the universe for the star and planet accretion, but is how many may even...

What I'd like to see is a three dimensional portrait of the galaxy and relative directional motion of it's different areas. The reddish dust lanes, if that's correct, leading toward the center appear to be rising up from the plane and returning toward the center. Just saying it has an appearance of...
