RE: Early stars
Isn't this stuff just amazing? I feel more "spiritual" than I ever have when I was religious. I always loved astronomy, but there was a belief in God behind the Big Bang. Now that I let that go, the uncertainty beyond the Big Bang is exciting. To know that I came from the core of stars just moves me every time I look up at the night sky.

I fucking love the universe. Bowing

A coup ? or a coupe ? Like the one, (Chevy) orbiting Pluto, (and YOU CAN'T prove there isn't). I'd have to enter the training program.

That's a whale of a tale.
I like that the story is from Kamchatka...the country that my sole knowledge about comes from the game Risk...Kamchatka for World Dominance!

RE: Early stars
Another question, today stars have more chemicals than the early stars. Scientists can look at the light of those stars and see from what chemicals they're made of. Are there still stars like the early ones who were made primarily out of hydrogen? Were the early stars different from the present ones? Was their lifespan shorter? How do more chemicals affect a star besides deciding what the colour prism is?

Not unless they formed in nurseries which has a pure supply of hydrogen available to them. The first Supernovas ruined that.

RE: Early stars
I'm Going To Be A Star

By Protostellar Molecular Cloud Barnard 631

I know what you're thinking, and it's true: In this big,
crazy universe, gaseous regions with the density and heat required to
ignite deuterium fusion are a dime a dozen. Any wannabe can overcome
internal pressure in order to initiate gravitational collapse. But
you're dead wrong if you think I'm going to let that stop me. I'm more
than some molecular cloud with the potential to have an unstable core,
and I won't just be almost undetectable molecular hydrogen forever. I've
got what it takes. Stardom, here I come!

Here I am, stuck in some podunk H II region not even visible to the
naked eye. Do I let that get me down? No way. Sure, the Horsehead and
Crab Nebulas have all the star-making rep, and if you're a young and
hungry mass of interstellar dust, gas, and plasma, they say it's not who
you are, but the supernovae you know. All I need is that one Big Break
to show you what I'm really made of. Point me in the direction of some
cataclysmic, entropic, destabilizing explosion, and look out, Milky Way!


Yes sir, once I get that fusion of heavy hydrogen underway, there's
no holding me back. After that, it'll only take a couple hundred
millennia before I'm on the scene. Then I'm gonna outshine everything
for light-years around with a candlepower unseen in this galaxy. Look,
the universe is just going to have to make room for this rising
circumstellar disc. After all, when you've got that kind of
electromagnetism, everything revolves around you.

I realize the outward pressure of the resultant radiation could slow
me down—happens to the hottest stars out there. But I'll be goddamned if
I muddle around in the obscurity of gradual accretion just to end up as
some pathetic, ancient black dwarf that no longer even registers in the
visible spectrum. When I get there, I'll work even harder, ceaselessly
raining down my remaining cloud matter until everyone recognizes me. If I
just fight through all the negative energy from the bipolar flow, the
solar masses of the Bok globules I create will be higher than this
quadrant has ever seen. You'll see. Twinkle, twinkle, little star?
Hardly. I'm going to be hot. The hottest.

I'm going main sequence, baby. The Big Time.

But when you're as hot as I'm going to be, there's bound to be a
downside. I'll have to deal with constantly having my picture taken and
getting my radiation, temperature, and rotation velocity routinely
measured. Other, lesser bodies will try to get in my orbit and share my
intense light. Any binary relationships I may have with other stars will
be placed under the telescope as well. But it will all be worth it, and
every body that comes in contact with me will have to understand that
when the time comes to expand exponentially—well, I can't be held
responsible for those destroyed.

I know that stars that hot only last one, three million years, tops.
But it's better to explode with 100,000,000,000,000,000 times the solar
luminosity than it is to fade away.

Don't cry for me, though: My legacy will extend far beyond your
lifetime. After my spectacular collapse due to hot-and-fast living,
you'll look up, and I'll be as bright as ever. No one will even know I'm
gone.

Not for at least 600 million years, anyway.
