In summary: Interesting question (to which I have no answer!) but:The "first" (whoever he/she might be) probably postulated that the sun was similar to the stars.If I should venture an answer, I would say Empedocles or Heraclitus (pre-Socratic philosophers).Perhaps a qualification is in order: the 'first person' to make that 'postulate' will surely never be known.

Well, this is not really a question from homework but it sounds like one, thus I decided to post here instead of posting in the Stellar Evolution subforum...

Who was the first one to postulate that the light sources in heaven are stars similar to the sun and which argument or ‘proof’ was given?

Thanks.

I think you have it backwards:
The "first" (whoever he/she might be) probably postulated that the sun was similar to the stars.

If I should venture an answer, I would say Empedocles or Heraclitus (pre-Socratic philosophers).

As to deducing from extant records which person appears to have been first to have such a postulate recorded, well we can of course answer that!

You will probably need to make a somewhat arbitrary demarcation too, e.g. 'myths not allowed'. Why? Otherwise a creative interpretation of one of the many thousand stories and myths of native Australians (or Africans, or New Guineans, or ...) could be used as evidence to support a claim.

Yes Nereid you are right, a demarcation is needed...

In fact, I was not really interested in the first myth or guess about the similarity of the sun and the light sources in heaven, but rather in knowing which was the first proof or the first solid argument for this.

After reading arildno's post I took a look to greek philosophers and it seams that Aristarchus was on the right track. Here

http://www.varchive.org/ce/orbit/arisam.htm

it is written that

Aristarchus regarded the Sun as one of the fixed stars, the closest to the Earth.

but it seams that nobody belived him. Also I did not found any argument. So this would not answer my question.

...thus the question is: which (and when) were the first reasonable arguments or proofs for the similarity between the sun and the light sources in heaven?

Regards.

FAQ: Who First Proposed Sun-Like Stars Exist? The Arguments Behind It

What evidence supports the existence of sun-like stars?

The main evidence for the existence of sun-like stars is observational data collected from telescopes. Scientists use instruments like spectroscopes to measure the chemical composition of stars, and they have found that many stars have a similar composition to our own sun. Additionally, the laws of physics and theories about stellar formation support the idea that sun-like stars should exist.

Who first proposed the idea of sun-like stars?

The idea of sun-like stars has been around for centuries, but it was not until the 19th century that scientists began to seriously discuss and research the concept. In 1838, German astronomer Friedrich Bessel published a paper proposing that other stars in the universe could be similar to our sun. Since then, many scientists have built upon this idea and provided further evidence for the existence of sun-like stars.

What are the arguments for the existence of sun-like stars?

One of the main arguments for the existence of sun-like stars is the principle of uniformity, which states that the laws of physics and chemistry are the same throughout the universe. Since our sun is a relatively average star, it is likely that other stars in the universe would have similar properties. Additionally, the abundance of elements in the universe supports the idea that there are many stars with similar compositions to our sun.

How do sun-like stars form?

Sun-like stars form through a process called stellar evolution. This involves the collapse of a nebula, a cloud of gas and dust, due to gravity. As the nebula collapses, it heats up and forms a protostar. The protostar continues to grow and eventually becomes a main sequence star, like our sun. This process is supported by observations of young stars and theoretical models.

What impact does the existence of sun-like stars have on our understanding of the universe?

The existence of sun-like stars has greatly expanded our understanding of the universe. It has allowed us to better understand the formation and evolution of stars, as well as the chemical processes that occur within them. It has also given us insight into the potential for other habitable planets and the possibility of extraterrestrial life. Overall, the discovery of sun-like stars has greatly advanced our knowledge of the cosmos and our place within it.
