Scientists Bring New Wild Theory for the Formation of Earth

Perhaps anybody wondered from time to time how our planet was formed. How did life begin on Earth? How did the human being begin to have rational and creative thinking? Why does Earth have such an unfathomable diversity of life forms?

But let’s return to the first conundrum. The classical scientific theory, to summarize it as much as possible, tells us that clouds of dust and gas surrounding the newborn star created planets while being under the pressure of gravity.  But a new theory will surely leave many of us speechless.

Collision of huge Moon-sized rocks led to the formation of our planet

According to Space.com, there’s a new theory explaining how planets the size of the Earth or Mars likely formed. Giant rocks the size of our Moon are likely to have been colliding together throughout many years to give birth to our planet and those of similar sizes.

Scientists analyzed 22 grams of material belonging to 17 meteorites that have their origin on Mars. The researchers further analyzed the isotopic composition of the samples gathered. The next phase was to compare levels of certain isotopes from Earth and Mars to those belonging to different groups of meteorites. The conclusion was that rocks from the Earth and Mars resembled meteorites from the inner solar system more.

Christoph Burkhardt, who’s the lead author of the study and a planetary scientist from the University of Münster in Germany, declared for Space.com:

We resolve conflicting interpretations of previous studies and show that Earth and Mars were formed from material that largely originated in the inner solar system,

Only a few percent of the building blocks of these two planets originated beyond Jupiter’s orbit. As such, we answer the fundamental question of what the Earth is made of, and this allows [us] to address the even more fundamental question of how Earth formed.

Feel old yet? Fast fact: the Earth has been around for 4.53 billion years.
