A mysterious marine-like planet could have made life on earth after a great impact

How did life on Earth begin, what made it possible and how did our natural satellite form be formed? These are just some questions that we all have asked and we have tried to find a reasonable answer.

Scientists believe that the moon was made with all the remaining material after Earth and a rock so big that Mars crashed 4.4 billion years ago. Through this impact, the Earth received most of the current carbon, nitrogen and volatile elements that support life.

Earlier studies theorized that meteorites were those that brought primordial material to help create life on Earth. His study was recently published in the Journal Science Advancements.

They observed all the primitive meteorites and impacts with the Earth and indicated the delivery of life through experiments. They discovered that the Earth's volatile elements that are essential for creating and sustaining life were delivered by the planet, giving them a sulphurous nucleus.

According to Damanveer Grewal, the lead author of the study, "the nucleus does not interact with the rest of the Earth, but everything that is on it, the mantle, the bark, the hydrosphere and The atmosphere is connected. Material cycles among them. "

Building blocks of life caused from outside our solar system?

The study co-author, Rajdeep Dasgupta, who is also the chief researcher of the CLEVER Planets project (funded by NASA), explains why this study can help us to understand the origin of our planet, and added that the essential elements of life can also come from outside our solar system:

"This study suggests that a rocky and Earth-like planet has more possibilities of acquiring essential elements of life if it is formed and grows in giant impacts with planets that have shown different building blocks, perhaps different parts of a protoplanetary disk ".

In addition, he added that silicate on Earth could not have produced our biosphere, the atmosphere and the hydrosphere, without the help of volatile elements that were introduced by another planet through a massive impact. You can consult an in-depth article about your study here.
