@ProfRob So your saying first the lighter elements formed from cooling and the heavier elements from heating up under there own gravity. Did the first proto stars have solar systems?

@controlgroup Your like cerberus at the gates of hell!! lol

@controlgroup Did the first protostar have an orbiting planet? I know it's a hypothetical question until it's not. No disrespect intended.

@controlgroup I don't want to sound dismissive however I don't like your counter-suggestion and dismissal its disingenuous. Although there may have been 'simultaneously' developed stars that did not have there own solar system this falls into the category that these protostars had to be formed by cooling from an initial plasma state. Plasma iron becomes a gas and a solid before hydrogen does the temperature scale.on earth proves this. Either the solar system came from a hotter thermal state and cooled or from a lower thermal state and heated up! Which is it ? Intergalacticly speaking?

Big Bang nucleosynthesis resulted in "mass abundances of about 75% of hydrogen-1, about 25% helium-4, about 0.01% of deuterium and helium-3, trace amounts (on the order of $10^{−10}$) of lithium, and negligible heavier elements".

A lot of stellar evolution occured before our solar system was born. Please see How can there be 1,000 stellar ancestors before our Sun? & astronomy.stackexchange.com/a/55456/16685

@PM2Ring I don't want to piss on your bonfire there are no halves or percentages found in reality those figures should not be taken seriously I deal with wholes, not their parts. However you break it down.

Sorry, I don't know what you're trying to say. But the point is that at the end of the Big Bang the matter in the universe was roughly 75% hydrogen, 25% helium (by mass), and negligible amounts of a couple of other light elements. There was certainly no plasma iron until a few million years later, after it was produced in stars.

@PM2Ring Thankyou for your reference. In your previous comment.

The very early stars were (probably) huge because of the lack of heavy elements. See astronomy.stackexchange.com/q/40206/16685

@PM2Ring How did the formation of our solar system happen earth is speculated to be of a majority of iron at the core and in the mantle aswell as are other planets such as mars. The formation of the sun and it's solar system had to be concurrent wirh the planets formation or before our sun formed or vice versa. It does not add up that the iron on earth was as a result of our sun spitting it out nor any other source of iron in the universe.such as mars etc or any other exoplanet. Iron solidifies when gases cool not when gases heat up!!

Right, the iron in the Earth wasn't "spat out" by the Sun. (And the Sun is too small to ever produce iron). The iron in the solar system was produced in large stars that died long before the solar system started forming.

The collapse of the giant gas & dust cloud that gave birth to our solar system (and likely many other star systems) was probably triggered by a nearby supernova. I have some info on that in astronomy.stackexchange.com/a/54582/16685

@PM2Ring If our solar system was formed from the gaseous explosion of an earlier star or a proto star how did the separation happen between the composition of the planets in the solar system and the composition of the sun?

@8Mad0Manc8 A stellar system forms when a giant cloud of gas condenses. However, that collapse process may be triggered by a nearby star exploding.

But anyway, the composition of the Sun and the planets isn't as radically different as it may first appear.

Condenses around what. Water condenses around a particle in the atmosphere?

The Sun and the 4 giant planets have a large proportion of hydrogen and helium. But that's just because they're so big, so they have enough gravity to hang onto those light elements.

But if you ignore the hydrogen & helium, the abundances of the other elements are fairly similar.

Does plasma condense?

BTW, the Sun has a lot more iron than Earth does.

@8Mad0Manc8 Sure. Once it cools down. That took a long time in the early universe. The original Big Bang plasma was glowing for around 380,000 years.

Which came first thermal energy or plasma or was it simultaneously. Sorry to quote first cause 😃

In the very early universe it was way too hot for matter as we know it to exist.

About a microsecond after the start of the BB, it was cool enough for protons and neutrons to stabilise.

I don't want to sound prophetic but your statement is prophetic the usual something from nothing. These simple paradigms are inescapable no matter how much science or theology you throw at them.

I didn't say anything implying "something from nothing". The universe was full of energy and matter from the first instant of the BB. But in the very earliest instants the energy density was so high that neither the energy nor matter was in the forms we typically encounter in the modern universe.

We can only speculate about the very early times, but we're more confident about conditions when the universe was around a picosecond old, because we can replicate that energy density in our particle colliders like the LHC.

Wikipedia has a timeline, with citations to 171 academic references.

@8Mad0Manc8 Except for spins, charges, weak isospins, weak hypercharges, color charges, connection coefficients, weak mixing angles, etc. etc. etc.... just saying. I agree with PM in that I couldn't respond to what you're trying to say because I don't know what you're trying to say, but I hope someone gives you an adequate answer eventually.

I'm just posing problems in the answer to your solutions!

OK...

??? What do you mean? You haven't answered "what is dark energy" or "what is dark matter" or "what happened in the instant after the Big Bang", so I think all our models are actually fine and have not had any questions answered for them.

Jesus your going have a heart attack at that rate. I'm in the UK we have a few defibrillators I hope there's so e around you 😃

? I am beginning to get the feeling that this conversation is going nowhere, so good day to you; I hope your question gets answered.

Seeya, @controlgroup

👋

You started it lol.
