While many will likely defend them to the death, a big problem with thinking about the heavens in the context of this forum (a designed universe) is that many of the theories of stellar and planetary formation leave a lot to be desired.
- Something blew up (supernova or several).
- The results then gathered together. -- But I thought they blew up? When was the last time you saw something taking spontaneous order?
- Then gas congealed, violating lots of known principles and not only did a star form, so did planets, without orbital velocity being wacky.
This grossly simplifies some things, but this is the reason I have such a hard time with the modern myth of Chance being the "new god." It doesn't make sense at so many levels.
Getting back to this blog though, even these wacky ideas are probably necessary to have a universe to explore. How do things keep going for the long periods of time to travel stellar distances otherwise?
