Why do some say we are remnants of the big bang when our sun is only around 5 billion years old?

Question

According to some scientists,the universe is around 18 billion years old,so if our sun is only around 5 billion years,then we are actually been recycle at least once from a previous star,therefore not part of the original big bang explosion

Answer 1

You're exactly right...! All of us are made of 'star stuff' from some ancient star that exploded at least more than 5-billion years ago. There are also countless atoms in our bodies that were created from the energy of the Big Bang.

Answer 2

I would like to argue it on the basis of some proven scientific data.

The sun is a medium yellow star.
It does not contain an appreciable amount of heavy elements which result from Fusion of hydrogen to helium to other heavier elements.

As you pointed already...the sun is about 5 million years old.
So you would agree that it has consumed a lot of the initial hydrogen fuel. This consumed hydrogen must have been converted over the course of 5 million years to higher elements.

So if I assume the solar system is formed from remnant of a previous star, then there would have to be a significant amount of heavy elements present.
The above observation is found true to some extent especially if you consider the planets.....but the sun is an major exception!

If I include another variable that disintegration or simply death of a star by an explosion like a nova or supernova rather than by formation of dwarf stars, the distribution of elements is indeed uneven. In essence matter is scattered all over space.

But a core remains behind whatever be the result. There hasn't been any such core or a dwarf star or a nebula detected with the radius of proxima centauri that is to say 4 light years.

So I guess it kind of refutes your theory.

Answer 3

No, according to almost all scientists, the universe is 13.7 billion years old. Yes, the non-hydrogen elements in our solar system are from the remnants of massive stars formed in the early universe. But pretty much all the hydrogen around was formed right after the big bang.

Answer 4

The Big Bang did not create all the suns and planets instantaneously. It took that much LONGER for the process of our sun to be formed from the matter created during the Big Bang.

Answer 5

No credible scientist says that.

It's generally accepted that our sun is actually a third generation star, based on the quantity and types of heavier elements our solar system is comprised of.

Answer 6

That's a slightly poetic way of stating that the origin of all matter, and therefore all life, originated in the Big Bang. Every extant particle, including those that make up the Solar system, has its origin in that event.

Answer 7

yes, 5 billion is close, god is not real. astronomers can now see with the hubble space telescope the formation of protoplanetary disks , the formation of planets is documented, there's no god required in this process.
