    Scale Universe
AI Thread Summary
The discussion highlights the organization of celestial bodies, noting that planets group into stars, which in turn form galaxies. It emphasizes that the observable universe, as seen through the Hubble Telescope, may not represent the full scale of the universe. The conversation points out the existence of galaxy clusters and superclusters, suggesting that galaxies likely form around dense black holes created during the universe's early expansion. This process is driven by gravity, which also influences the formation of solar systems around massive bodies like suns. Overall, gravity plays a crucial role in the structure and formation of the universe.

If you look at the planets, they group into a star, which all form a galaxy. It just seems like everything groups together. Our observable universe with the Hubble isn't as enormous as the universe may be. If so, galaxys would form an even greater cluster and so on and so forth.

It's called gravity!
 
There are galaxy clusters and superclusters, yes.
 
Galaxies probably form around very dence black holes to begin with. The black holes probably formed at the earliest stage of the expansion when things were very close together bringing about the galactic formations. Solor systems form around massive bodies such as suns in the same way. All because of gravity.
 

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.

Thread 'Venus and Jupiter Conjunction'

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
