Suppose no stars more massive than the Sun had ever formed.Would life as we know it have been able to develop?

Question

Please explain the reason :)

Answer 1

no

when matter first formed in the universe, the only elements available were hydrogen, a little helium and perhaps a trace of lithium. one or two teaspoons worth of a trace. heavier elements, including carbon and oxygen, are formed as the result of stellar fusion

stars up to the mass of the sun are only capable of fusing elements as heavy as silicon before the fusion process ceases. the outer layers of the star do get blown off, back into space, but still consist overwhelmingly of the hydrogen and helium that was there all along. the heavier elements stay in place in the dead core of the star, right where they were formed

it takes larger stars than the sun to produce elements heavier than silicon, AND to explode so that those elements end up somewhere in the universe where life can develop

the universe's first stars, being composed almost entirely of hydrogen, were massive beasts larger than any stars now known, and ran through the entire fusion process in only a few thousand years. at the end of their lives, these stars exploded as supernovæ, and various amounts of every element up to uranium (though mostly even-numbered elements from beryllium through iron) were scattered throughout the universe

gravity has since caused this material to come together again, this time as planetary solar systems. sometimes, a planetary body will coalesce at just the right distance from a stable parent star (or configuration of stars), and liquid water, with its stellar-forged oxygen atom, will be available to spark also-stellar-forged carbon-based life on its way

Answer 2

There would be no rocky material that lead to the formation of the solar system.
It may even be that One solar mass stars could not have coalesced from the original hydrogen field.
If this had been the situation it is difficult to say how a universe could have evolved at all.
However the materials that were forged in massive were required to produce us.

Answer 3

Probably not. Wouldn't be enough heavy elements. It probably took the material from atleast one very massive supernova or the combined ejecta of several to form our solar system and the remarkable array of elements it contains. Without massive stars there would be no supernovas and new star formation would be a very slow process if possible at all.

Answer 4

No; our highly metalliferous sun and solar system came about as the result of the coalescing of the gas and dust shells resulting from 4 supernovae, which can only occur in stars much more massive than our sun.

Answer 5

IMO///Yes...because at least we would have something like the sun...and we are here because of the sun...

Also, there is an area of habitable zone around stars and if a planet happens to be in it, life may develop. The range of the habitable zone varies according to mass of star...the large the star, the further away it is...so it is more important whether any planet lies in the habital zone...

Answer 6

No.

If the largest stars were the size of the sun there would be no elements in the universe beyond iron, because these are all formed by larger stars. Such elements are essential to life.

Answer 7

It is possible coz around each stars there is a ideal zone for living provided the planet around that star has necessary atmosphere to support a living system

Answer 8

I try this each and each morning. it fairly is my on my own time. My time to in basic terms think of and don't something till the busy day takes over. i admire seeing the solar arise, listening to the birds and seeing the rabbits and squirrels working around. that is those straightforward pleasures that interest my memory to decelerate and enjoy issues in existence. existence protecting... a clean day and that i'm nevertheless in it. : ) i will nevertheless savor it.
