The Earth is actually two planets - not one

Scientists have determined that the Earth and moon are made up of material from two separate worlds.
Somewhere around 100 million years after the Earth was formed it had a run-in with another planet known as Theia, but while previous studies had suggested that the two worlds had only side-swiped one another, new research has revealed that they were most likely involved in a head-on collision.

The cataclysmic smash was so destructive that Theia was reduced to a cloud of debris which gradually merged together with the Earth to form both the moon and a single, larger planet.

The research was based on a new analysis of rock samples retrieved during the Apollo moon landings which showed an identical ratio of oxygen isotopes to materials collected on the Earth - something that shouldn't be possible if the Earth and Theia had only side-swiped one another.

"Theia was thoroughly mixed into both the Earth and the moon, and evenly dispersed between them," said UCLA geochemist Edward Young.

"This explains why we donít see a different signature of Theia in the moon versus the Earth."

Or... Maybe the moon rocks are from earth, because the moon landings were faked. Occam's razor, people. G'day JimmyKrajeski, and welcome to UM. Ockham's Razor is always a good place to start when looking at a problem. However it's also important when using it to ensure we have all the information when using OR. In this case, where the only mention of Moon rocks is their similarity to Earth rocks, it's tempting to assume they actually are Earth rocks. If that was all the information we had to judge whether the Apollo missions were faked, then that would be a tempting conclusion. But what the ar... [More]

I dont know i didnt read what he wrote i was just going off the other comments thanks for the usual melodrama. Oh please. There was no "melodrama". You were rightfully and unmelodramatically called out by a total of two people for claiming that what Sitchin wrote "was coming true" when Sitchin's fantasies are nothing like what is being proposed by actual scientists. You should grow a thicker skin if you're going to be posting online.

I tend to go with the collision theory, where the Earth and the other planet collided and it was debris which formed the Moon. Due to the fact that so little heavy elements ended up on the Moon. (Or has that idea been debunked??)

(Or has that idea been debunked??) No, it remains very much at the core (okay, pun intended) of the Giant Impact theory.

Now it begs the question, where did life originate, Terra or Theia? Or was it that interaction of the two bodies that caused life to form, something about the collision which over time ushered in life? What a fascinating discovery. Plus where did the other planet originate the galaxy that collided with the spiral or the spiral?

Plus where did the other planet originate the galaxy that collided with the spiral or the spiral? There is no reason to think that the planet that collided with Earth didn't also come from the Solar system, so what does spiral galaxies have to do with this ?

Plus where did the other planet originate the galaxy that collided with the spiral or the spiral? No need to involve the galaxy. Everything that happened to create the Earth-Moon system as it is today originated in the forming Solar System, which was...well let me go back a couple of steps. 1. The Solar System (that is, the Sun, the eight planets and their moons and the various dwarf planets, asteroids, comets and so on) is believed to have originated in a cloud of dust and gas which slowly coalesced, probably under the pressure of a shockwave from a nearby supernova. 2. As the cloud coalesced... [More]

What a fascinating discovery. doesn't matter since the two planets were destroyed, thus life on both planets would have been destroyed. besides this is the theory of how earth got a moon.
