Imagine a star 30 times thr mass of the sun made of iron. Explode that star into an expanding sphere of iron atoms and by the time it reaches a radius of 1 light year, I bet you would not have any two iron atoms within an AU of each other. Not to mention that thc atoms would be going .99 times the speed of light and the escape velocity of a single atom of iron aint that much.

that’s a Bizzarro theory

‘Bizarro theory’ — how droll!

Once those AU atoms slow, they’re subject to the Law of Gravity, I suspect.

Will they drift aimlessly forever? Will they loiter in deep space, doing nothing? (Yes, I am deep in the thickets, and sinking!) Or will they eventually cluster where iron will do its chemical best to brood life.

Only the Lord knows.

Eeh, gads! A lover of science and order who believes in God? You bet ‘cha!

Einstein was right; God does not play dice with the universe.

I write schlocky sci-fi here and there.
One trope in sci-fi is “God as unknown alien intelligence creating man”.
I took it one step further: man genetically modifies lower lifeforms to insert human level intelligence, the resulting creations wondering about the Creator of their creator.

The universe is weird, LL Pegasi is a nebula one third of a light year across that faintly glows green.
Inside it two extreme carbon stars orbit each other.

And Einstein was right, He doesn’t play dice.

We are also blessed to be where we are st.
Active galaxy 3C 321 has relativistic jets, one of which is blasting the crap out of a neighboring smaller galaxy.
I wouldn’t want to be on the receiving end of that.

“1:1 - In the beginning God created the heaven and the earth.
1:2 - And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
1:3 - And God said, Let there be light: and there was light.
1:4 - And God saw the light, and it was good; and God divided the light from the darkness.
So, the cosmos was without form, Big Bang created light, long after a local star went supernova for MORE light, and the resulting caused the solar system to form; fish were formed before man, man came about in God’s spiritual image having the capacity to think and understand good and evil, and our human nature leads us to choose what is selfish rather than think first of others. Science again runs parallel to Scripture.”

Why must we think of others first? Why is it wrong to be selfish if selfishness means concern with ones own interests. Why can’t we be primarily concerned with our own lives and happiness and concern ourselves with others when we choose to? Because “God said so” or “the bible said so” is not a rational reason. No one has ever given me a rational answer to these questions. Don’t we first have to take care of our own needs before we can help others? Do we exist to serve others’ lives and never our own? Why do you feel the need to make such a statement on a thread about a supernova? And by the way you pulled a fast one and changed the wording from “in the beginning the Earth was without form” to “in the beginning the cosmos was without form”. Now why did you do that? Earth came much later than the big bang. And isn’t it true that man was not created with the ability to understand good and evil according to he bible but gained that ability from eating the forbidden fruit, for which he was thrown out of the garden and became fallen?

From what I have read all elements above Iron are created during supernovae. But yes the Iron in your blood was created in a star as was the Carbon and Potassium and every other element above Hydrogen.

Deep thought references in the arts: MIB touched on this with the locker sequences and the ending, no?

I sometimes wonder if we are some teenaged alien's science fair terrarium project ... what happens when the judging is over?

Like all good mad science projects, we get turned loose upon the universe.

Imagine a star 30 times thr mass of the sun made of iron. Explode that star into an expanding sphere of iron atoms and by the time it reaches a radius of 1 light year, I bet you would not have any two iron atoms within an AU of each other.

Let's do the math. The amount of iron ejecta from a Type II supernova isn't known for certain, but one rough estimate claims it to be about half the mass of our own sun, or about 1030 kg. One light year is about 1013 km. The volume of a sphere of that size (4/3 pi r2) is about 1026 cubic kilometers. Divide that by the mass of the ejecta (1030 kg) and you get 10,000 kg of iron per cubic kilometer.

This of course assumes a uniform distribution. Actual supernovas produce complex wavefronts (see the Crab Nebula) where the local density might be might higher.

Anyway, at 10,000 kg per cubic km you get about 10 micrograms per cubic meter. The atomic weight of iron is 55g/mol. Multiply by Avogadro's number (6.02 x 1023 atoms/mol) and you get 100,000,000,000,000,000 atoms per cubic meter.

That's a teeny weeny bit larger than 1 atom per AU.

Wait a sec, Einstein denied that God played dice with the cosmos... ;’)

The lines quoted at the top...the ones with chapter and verse say Earth. The lines that do NOT have chapter and verse are my own long view of what the scripture is saying, nothing more. So no, I did not "switch" anything, I applied my own point of view to Scripture, and it is clearly noted as such.

To ancient peoples without science who knew the stars as only lights hanging in glass domes, Earth would BE the cosmos. I merely sought to show how the Genesis that some take as literal (I don't) runs parallel to science if you allow it to. Clearly Earth is mentioned later than the creation of Light. Works for me.

Well that's big iron. I knew that the sun is about 8 light min from earth so I could have easily calculated 1ly=65700AU a number much smaller than I would have guessed. And a half solar mass of 1030 kg is mind bogglingly large to me, much larger than I would have suspected. In my imagination I was applying the inverse square principle to an under esteemed mass over an over esteemed light year.

Notwithstanding that your formula for the volume of a sphere is off by a order of magnitude of the radius, my imagination stands metrically and mathematically corrected. Thank you sir!

I'm still curios about how all that fast moving matter could coalesce to form asteroids and planets. I'll read the article. I'll also read about the history of the solar mass estimation. That's really facinating.
