The world’s first reproductive molecules were produced – | Iranian and world news

Researchers have produced the world’s first molecules by imitating the world’s conditions at the time of emergence, according to . The findings of this study change our understanding of the root of the stars in the early world and reflects the re -evaluation of the combination of helium in the early state of the world.

The world was exposed to a very high temperature after the big explosion of 1.5 billion years ago. But a few seconds later, the temperature declined to form hydrogen and helium as the first elements.

According to researchers, a helium hydride ion or HeH+became the world’s first molecule. This ion is needed to form molecular hydrogen and is now considered to be the most accessible molecule in the world.

In order for a pre -star to start a fusion process where the stars can build their own energy, its atoms and molecules must collide with each other. This process is not efficient at temperatures below 5,000 degrees Celsius.

But hydride helium ions are very suitable for continuing this process and can even do it at cool temperatures. For this reason, they are an integral part of the formation of stars in the early world. Therefore, the amount of helium hydride ions in the world may have a significant impact on the speed and efficiency of the initial formation of stars.

The researchers reconstructed the initial reactions of helium hydride by storing ions at a negative temperature of 2 ° C for 5 seconds to cool them before compulsory collision with heavy hydrogen. They examined how these collisions, which are similar to those that start fusion in a star, change depending on the particulate temperature.

They found that the reconstruction rate between these particles did not decrease at lower temperatures, which contradicts older assumptions.

“Previous theories had predicted a significant decline in the likelihood of a reaction at low temperatures, but we could not confirm this in neither in experiments or in new theoretical calculations,” said Holger Grinkle.

This new discovery on how helium hydride ions works challenges the understanding of how the stars are formed in the early world. According to Grinkle, the reactions between these ions and other atoms for the chemistry of the early world appear to be much more important than previously thought.
