The universe was very different when he was young. Recently, astronomers discovered that complex physics in young cosmos may have caused the development of supermasif stars, each weighing up to 100 thousand times the mass of the sun.
We currently have no observations about the formation of the first star in the universe which is thought to occur when our cosmos is only a few hundred million years old.
To understand this important age, astronomers turn to sophisticated computer simulations to test the model of how the first star is formed.
Over the years, astronomers struggled with questions about how typical sizes of the first stars. Some initial estimates estimate that the first star can be hundreds of times more massive than our sun today, while the next simulation shows that they are more normal.
Recently, a research team has compiled a new simulation round and reached a very surprising conclusion. Their simulation specifically observes the phenomenon known as cold accretion. To build a big star, we must draw a lot of material into a very small volume very quickly.
And we have to do it without raising the temperature of the material, because warmer material will prevent him from collapse. So, it takes several methods to eliminate heat from the material because the material will collapse very quickly.
The previous simulation has found the appearance of a solid bag in an early galaxy that cools quickly because it emits radiation, but does not have the resolution needed to follow the next evolution.
New research takes further steps by checking how cold solid bags that were originally formed in the initial universe behaved.
This simulation reveals that the large flow of cold and solid material can attack the accretion disk in the center of giant material lumps. When that happens, shock waves will form. The shock wave quickly made the gas unstable and triggered the collapse instantly the big material pockets.
The large pocket can be tens of thousands of times more massive than the sun, and in some cases even 100 thousand times more massive than the sun. Without anyone stopping his collapse, they immediately formed a giant star, known as a supermasifmist.
Astronomers do not yet know whether the supermase star is formed in the early universe. They hope that future observations using the James Webb space telescope will express instructions about the formation of the first stars and galaxies and determine whether this monster appears in the 'baby' universe.
