The environment was different when he was young. Astronomers have recently discovered that the complex physics of that tiny space may have led to the formation of supermassive stars, each weighing 100,000 times the mass of the Sun.
We are currently not seeing the formation of the first stars in the Universe, which is thought to have occurred when our cosmos was only a few hundred million years old.
To understand this important moment, astronomers use the most advanced computer systems to see how the first stars formed.
For many years astronomers have grappled with the fundamental question of what the first stars were like. Some early calculations predicted that the first stars could be several times larger than the Sun, while later simulations showed that they would be appropriately large.
Recently a group of researchers have created a new parallel circuit and reached a very surprising conclusion. Their experiments focused specifically on a phenomenon called cold accretion. To make big stars you have to squeeze a lot of material into a small volume very quickly.
And you have to do it without raising the temperature of the things, because hot things protect themselves from falling. So you need some way to get rid of the heat from things that are falling apart very quickly.

Previous modelers had discovered the appearance of pockets of ice inside early galaxies that rapidly cooled due to radiation, but had no idea how to track their evolution.
This new study is a step forward in investigating how the cold pockets that originally formed in the early Universe behaved.
These simulations revealed that large outflows of cold, dense matter can hit the center of large bodies of matter. When this happens, the threat begins. These shocks quickly disrupt the gas and cause the collapse of large pockets of material.
These supermassive masses can be thousands of times larger than the Sun, and sometimes even 100,000 times larger than the Sun. With nothing to stop their fall, they immediately form massive stars, called supermassive stars.
Astronomers still do not know whether the most massive stars formed in the early Universe. They hope that what will happen in the future using the telescope called James Webb Space Telescope will show how the first stars and galaxies were formed and find out if these monsters appeared in the early Universe.
