Protons for the emergence of life.

For Vladimir Airapetian, NASA stellar astrophysicist, he points out a new idea. He posed the following question and whether the origin was in energetic particles from the sun. To arrive at this idea he based himself on data from NASA's Kepler mission, a composite mission. of a space observatory that for years investigated distant stars at different stages of their life cycle.

Seeing how stars similar to the sun behave when they are young gives us an idea of what the sun must have been like in its youth and that basic idea was taken by Airapetian, in 2016 he published a study that suggested that During the first 100 million years of the history of the earth the sun was 30% darker or put another way it was 30% less bright than it is today, but it was much more active with many more solar super flares.

Super flares are powerful eruptions that we currently only see luckily once every 100 years, more or less, but during the early life of the Sun in its juvenile stage more than 4 billion years ago, super flares would have exploded. at a rate once every three to ten days practically a super flare or two a week.

These super flares launch particles at a speed close to that of light that when colliding with the Earth's atmosphere initiate chemical relationships, that is Airapetian's theory but proof had to be put, so together with a team of researchers they designed their own primordial soup experiment created a mixture of gases that coincided with the atmosphere of the primitive earth, but not as was believed in the 50s but with the updated data as we currently want what the atmosphere of the earth was like in its early days.

So they combined carbon dioxide, molecular nitrogen, water and a variable amount of methane, the proportion of methane in the early atmosphere of the earth is uncertain, but it is believed to be quite low, with this combination, with this primordial soup they made the scientists two experiments.

In the first, they fired the mixture with protons, thus simulating the action of solar particles, and in the second, they fired the mixture with discharges of sparks, thus simulating the action of storm lightning, and in this way they also repeated the experiment over the years. 50 of the Miller-Urey experiment in order to compare the results.

The conclusion was spectacular: the protons that imitated solar particles could create amino acids and other organic molecules with only tiny amounts of methane, and they also did so a million times in greater quantities than the organic molecules produced by the rays.

This means that, other things being equal, solar particles are a more efficient source of energy than lightning from storms, with an added bonus: in that primitive era, lightning storms must have been less frequent on Earth, since the sun It was much less bright and the earth was surely colder.

In conclusion, these experiments show us that our young and active sun could have provided the energy necessary for the creation of the molecules that gave rise to life and that this process could have occurred earlier than scientists assumed.
