Scientists Now Offer Compelling Evidence: Earth Could Be The Result Of A Collision Between Two Early Planets
The origins of the moon have been a fascinating study over the last couple of years. It has almost been determined for quite some time that the Earth’s lone and natural satellite wasn’t captured, as Mars’ moons, or the result of some other natural phenomena. It’s long been thought that a collision took place with the Earth and some other massive object in the early stages of our solar system, causing for some of Earth’s mass to be ejected from the surface to form what mankind now knows as the moon.
This theory of a planetary collision forming the moon only was supported by a 2014 study that seemed to suggest its authenticity. The object that was said to have collided with Earth called Theia, the mother of the moon in Greek mythology, should have made up a majority of the moon’s surface material. This means that the Earth and the moon should have fairly different chemical signatures. While the study mentioned previously suggested that this was the case, a new UCLA study apparently disproves it. Their rather compelling study has been concluded and offers verifiable evidence that another kind of collision is indeed responsible for the formation of not only the moon, but of the third planet from the sun itself.
We know that Mars has a different complement than Venus, and Venus has a different complement from Earth, etc., but the fact that the Earth and the moon basically have the exact same composition of material means that they were in all likelihood even made at the same time. Moon rocks brought to us from the Apollo 12, 15, and 17 missions were also analyzed and then compared to the analysis of volcanic rocks from Arizona and Hawaii.
Finding that they essentially had the same isotopic signature, is pretty compelling evidence that Theia and the Earth never actually collided as the former theory said. Instead it’s more plausible, that Theia and some other planetary body likely hit head on, destroying both planets in the process and forming two new objects from the ruin: Earth and its lunar companion… and this is definitely an exciting discovery, one which could very well “re-write the science books,” as some say.
What’s truly exciting to see, however, is just how far technology and science have progressed so that answers that man once thought were impossible to know by the scientific method of that time are now unfolding before his very eyes.
