Even if it did, when that core material which is much smaller and cooled off to a "cool" lump of **** in many millennia or millions of years later, how would you detect it from many light years away?

OP wasn't questioning the whereabouts of our sun. He was wondering where the star/s that gave the materials that our solar system is made of, is.
The mystery is, we don't know the sizes of previous generation stars that kicked the bucket and passed on their "genes" to us.
I was asking a simple question but somehow there are couple of people here makes things sound more complicated than it is necessary. Or is it complicated? idk.
Anyhow, when a star explodes, the gaseous cloud is bounded by gravity to the star so they would move in tandem. They are bounded by the force of gravity.
They cannot move away from each other.
When the gaseous cloud ejected from the star, they move in very high speed away from the star and based on conservation of momentum, they would continue to move away from the star at the initial velocity. Since our solar system is about 5 billion years old, our solar system has move away from the star in that 5 billion years. And depends on the initial velocity, that would determine how far away our solar system from its parent star that gave it its birth.

These are likely to be high-mass stars that form and die quickly.
Low-mass stars use hydrogen fuel so slowly that they can shine for 100 billion to 1 trillion years.
Since the universe is only about 13.7 billion years old, this means no low-mass star has ever died.
Once the star explodes, it no longer has the gravity it once had. I think you are mixing the physics with the rocket launching from a planet.
They do move away from each other because the trajectory of movement is radial so further they are ejected, further each element gets separated from each other.
Is this a new subject now?

Found this info on the web that may give a hint as to how far the solar system is away from its parent star.
Speed of light is about 6.706e+8 per hour.
The gaseous material travels at 4e6 miles per hour away from the star.
In 5 billion years, the solar system would be about = 5 billions years * ( 4e6 / 6.7e8) = about 29 million light years away.

Who said the big bang and conception of our universe/s was the explosion of a large star?
I don't think I hear that one before.
I remember a theory about the big bang, something like a collision of matter and antimatter which caused the big bang and rubber band theory.
No idea if that is a technical enough parlance, or if it is a theory now since abandoned
No it was more a question of "did I miss something in my very basic knowledge?"
Not a criticism, but not clear either.

It will be interesting the mechanism of how the cluster would break apart - probably from collision with each other. This "break apart" is probably the cause of how the solar system was separated from its parent star.
You remember correctly. Allow me to expand.
The current thinking is that the Big Bang wasn't the beginning of the Universe. There was a period of rapid inflation which preceded it, during which the size of the Universe increased many, many times over.
During this exponential inflation, the energy that is intrinsic in cold, empty space itself was transformed into the hot dense soup of matter, antimatter and radiation that set up the conditions for the Big Bang. The transition from an inflationary spacetime into the beginning of the Big Bang is known as cosmic reheating.
The initial period of extremely rapid inflation set up the entire observable Universe and created the conditions for the Big Bang which produced the Universe we observe today. If you think about it, this explains why the Big Bang occurred everywhere at once, and not at a single point in space.
Ethan Siegel explains this hypothesis is some detail in the link below - I've simply extracted some of the more understandable information - he's cleverer than me - I'm just a 🤓!

As explained earlier, the newly formed stars in a nebula are thrown apart due to internal gravitational interactions.
In fact, stars rarely collide - unlike entire galaxies which often collide - the difference being to do with the relative packing densities of stars and galaxies.
