RE: Let's Learn Something Cool - The Solar System (The Trolls Are Back!)
"At a rough guess our solar system is about 4.6 billion years old. "
I'd hate to have to be the one to blow out the candles at the birthday parties. 4.6 billion of them! geez!
So, let me get this straight. Was our whole Milky Way galaxy this "primary cloud" which began to cool down, or just our solar system part of it?
And all those other galaxies. Were they part of this "primary cloud" too?
Before the Big Bang, was it so quiet that you could hear a pin drop?
Are your trolls trolling us?
I just wanted to comment on this question of yours. Theoretically, the big bang is the moment in the universe's history where time started to be defined. Therefore, there is no "before the big bang" moment and your question cannot be answered :)
What good is a question that can't be answered?
I know!
"A man's grasp must exceed his reach
Or what's a Heaven for?"
Okay, you got one point here. :p
Please let me try to reformulate: 'In the context of Standard Cosmology, your question cannot be answered as it goes beyond the domain of application of this theory'.
Is it better? :)
But, but, but, my question wasn't formulated from the standpoint of, wait for it, dum tada dum........"Standard Cosmology".
It's more the sort of thing that goes through what's left of my mind when I'm assisting the Heyoka at a Sundance.
Woah! Lots of questions!
Let's sort it out with a story:
Once upon a time there was total darkness and silence until one bored child decided to light a match and then BOOM! Helium and hydrogen gas scattered and formed big clouds! The little child was so excited to see how the clouds then either started to form stars which gathered and made the protogalaxies or the protogalaxies were formed first and within them smaller clouds gave birth to stars (we don't know that yet).
The stars in those protogalactic masses were soon put out and the little child got disappointed. But the disappointment did not last long. Soon new stars started popping from the countless clouds like fireworks on a New Year's night and galaxies were made.
Those galaxies kept travelling around the universe, meeting one another, sometimes merging to form bigger clusters of star neighborhoods. The little child is still out there, watching this colorful and noisy experiment go on and on and on until...no one knows!
How does that sound?
Have you ever heard the phrase: "It's turtles all the way down."?
If not, ask me about it some time.
Nope, never heard of it, what does it mean? :)
The natives of North America call the continent "Turtle Island"
A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man, very clever," said the old lady. "But it's turtles all the way down!"
"Turtles all the way down" is a jocular expression of the infinite regress problem in cosmology posed by the "unmoved mover" paradox. The metaphor in the anecdote represents a popular notion of the model that Earth is actually flat and is supported on the back of a World Turtle, which itself is propped up by a chain of larger and larger turtles. Questioning what the final turtle might be standing on, the anecdote humorously concludes that it is "turtles all the way down".
The expression is an illustration of the concept of Anavastha in Indian philosophy, and refers to the defect of infinite regress in any philosophical argument. Contrary to most extant western references, it is not a popular Hindu belief." Wikipedia
Thank you for that!
It reminded me of Atlas, who was punished to hold the skies. Could turtles derive from Atlas?
turtles - turtlas - tartlas - atlas? :P
Jokes aside, myths are fascinating and human imagination can create amazing stories. It's funny though how some ideas remain the same within different cultures.
Logic and (modern western) science take place in the conscious mind. The subconscious is much more powerful and makes little or no use of logic at all! It's language is that of myth and dreams.
And there are theories of a deeper still "collective" consciousness which might explain the recurrence of mythological themes throughout history and across geological barriers.
