quote: I can appreciate your opinion, but the fact still remains that a actual model in physics is nonexistent, concerning even a single star formation in the early universe. The parameters under which star formation could occur involve more than undetermined apparatus , but defy physical phenomena (gas action in a vacuum). My opinion is that star formation can not be assumed to have a specific time value if we do not know the mechanism.

quote: Well I might bring up the fact that the oldest known star in the universe is HD 140283, which appears to be 14.3 billion years old, slightly older than the universe. Well if you consider the error of estimation to be .8 billion years, this star supposedly formed shortly after the big bang (although there is no evidence a star could form at all). It is interesting to note that it is a population II star, having low concentrations of metals. So you would have a population III star (mostly hydrogen) form, age and become a super nova in less than 400 million (corrected) years. Then HD 140283 formed from population III supernova in that same 400 million (corrected) years. This seems (Impossible) unlikely.By the way population III stars apparently don’t exist or have never been observed. Population III should be very plentiful at long distances as observed from earth. SeeStar found, older than Abe Vigoda HD 140283 - Wikipedia quote: We are just getting started. Edited by zaius137, : No reason given.

quote: You miss the point completely, the problem is relating the age of the universe. We can see objects 45 billion years ago in time (but light could only have traveld 13.4 billion light years). It is not a matter of relating the speed of light to distances, it is a matter of the assumed inflation epoch. citation for the visible universe (size not age).
According to calculations, the comoving distance (current proper distance) to particles from the CMBR, which represent the radius of the visible universe, is about 14.0 billion parsecs (about 45.7 billion light years), while the comoving distance to the edge of the observable universe is about 14.3 billion parsecs (about 46.6 billion light years),[1] about 2% larger.
Observable universe - Wikipedia Here are the 3 ways you measure he age of the universe. http://www.astro.ucla.edu/%7Ewright/age.html By the way good information anyway. Edited by zaius137, : No reason given.

I missed the cosmological estimation of age of the universe. Sorry, here is a brief description:
"Measurements of the cosmic background radiation give the cooling time of the universe since the Big Bang,[2] and measurements of the expansion rate of the universe can be used to calculate its approximate age by extrapolating backwards in time." wiki This related to more of my point than the other estimate methods.

quote: You are correct. Unsure about the exact accepted age of the universe at this time, I will correct it to 400 million years. Nobody is reading this except you.... thanks Edited by zaius137, : No reason given.

quote: Since HD140283 is older than the estimated age of the universe with an uncertainty of .8 billion years. The 400 million years would be the overlap of uncertainties between the age of the universe and the age of HD140283. I would claim that HD140283 would have to have formed 400 million years after inflation. Likely this time frame would be impossible, because some Population III stars would have to have formed, aged and went supernova before HD140283 could have formed (that by metals available in the early universe).

quote: I challenge you to read and find out what Genesis 1 says. The heavens and the Earth were first created then afterward was the six days of creation (concerning electromagnetic radiation, earth from a void state and life). The 6000 years you speak of do not allow a gap between the creation of the heavens and the Earth and the 6 days of creation. The gap is just some interpretation I happen to agree with. I am not set in stone on these issues because my understanding is always improving with information.

quote: There is an inconstancy with population III stars, if they were large and ended in supernova they were likely to have dispersed the metals they formed. If they formed black holes the metals they formed were sucked in. Waive your hands to make all the problems just go away.
quote: Restating my point: There was not enough time for HD140283 to have formed since the end of inflation. Simply because population III stars did not have enough time to form, age and go supernova. HD140283 was a low metal star not a zero metal star when it formed. Your assertion that Population III stars are super massive is even outdated. Large, short lived stars in the early universe create more problems than they answer. Consider the following
Population III stars were not only smaller than believed, they actually formed in binary systems, that is, pairs of stars that orbit a common center, say the results of a new simulation. Population III Stars And The Early Universe Get A New Hypothesis | Science 2.0 Smaller stars with less initial metal last longer. So there goes the short lived population III idea. Also population III stars have never been observed (your whole point could be a fairytale). There is a struggle to produce a realistic star formation model without producing numerous paradoxes. So far there is no comprehensive and scientific star formation model. All your hand waiving about stars and there formation is pure speculation and off subject. We were discussing the age of the universe. I still say that stars add nothing to question of the age of the universe.

quote: I will give you point 1 I think CMB is a better gauge for universe age as it relates to BB. When we talk about age, you may not be considering GR and maybe a gravity well effect for time. This would be a characteristic of a cosmology that disregards the current cosmological principle. NoNukes has set the current topic of this conversation, I am waiting for NoNukes to run out of gas. Let us talk about your points when the former permits.

That is just funny You know God loves the ignorant too At least the un-willful ones.
