A “time-traveling” experiment has created precursors to life from seemingly “lifeless” Earth molecules in the Great Fire.
pig Sci-News, a research team tried to reproduce the famous experiment of scientist Stanley Miller from the University of Chicago (USA) in 1953, which managed to create 20 types of amino acids from methane, ammonia, d water and molecular hydrogen, as well as artificial lightning.
Dr. Miller’s experience is considered “half success” for actually helping to create certain amino acids, which are considered the building blocks of life, although a way to transform these amino acids into more complex forms has yet to be found.
Another big question: Will the clay be enough to produce the required number of amino acids?

New research, led by Dr Vladimir Airapetian, an astrophysicist at NASA’s Goddard Space Flight Center, shows that this path may be correct, but if we replace lightning with energetic particles from the solar sky, the effect will be more obvious. .
ƝThe research team strangely recreatedi Earth conditions in the Great Citadel of Firealso called “Old Taiyuan”from the birth of the Earth (more than 4.5 billion years ago) until 3.8 billion years ago.
On this hot, ancient planet, the Sun is about 30% dimmer than it is now, but emits powerful streams of energy every 3 to 10 days.
They combined carbon dioxide, molecular nitrogen, water and varying amounts of methane in each sample, capturing the mixtures with sparks that simulate lightning or protons that simulate the flow of solar energy.
The results show that cosmic energetic particles fired from the Sun produce more amino acids and are more diverse than those fired by lightning. This source of energy is more abundant than lightning.
“These experiments suggest that the young and very active Sun could be the catalyst for the precursors of life, more easily and perhaps earlier than previously thought.” magazine publishing Life confirm.
