Vor etwa viereinhalb Milliarden Jahren Der Planet Theia prallte auf die Erdezerstörte Theia, schmolz große Teile des Erdmantels und schleuderte eine riesige Trümmerscheibe heraus, aus der später der Mond entstand. Wissenschaftler fragen sich seit langem, woraus Theia besteht und woher es kommt. Jetzt Sie haben Beweise dafür, dass es sich ganz in der Nähe unseres Zuhauses gebildet hat.

Stupid question, why scientists wonders what it was made from? Our planet and the moon is where it’s remains are. So it was made of that stuff. No?
This feels like the ship of Theseus when it comes to Earth today and Theia/Old Earth.
Was Theia actually destroyed by Earth or did Theia and old Earth ombined to make a new planet?
All that empty space and you had to walk into my garden
Makes you wonder what the skies were like pre-collission. Did Theia appear in the sky periodically and just over the years came closer and closer? Imagine if the moon had a cycle where it appeared in the sky and grew larger and larger until a certain point before shrinking away again. Not just shadow cast from Earth, but moving closer and further, even disappearing for a bit, along with the shadow effect.
Silly, everyone knows the moon is made of cheese.
Was this always the theory? That it was an inner solar system planet? I also remember reading that all inner planets tend to be terrestrial because of what they are made of. So, this kinda seems like it had to be this way.
Was this even in question? I mean did anyone think it came from the outer portion of the solar system? That would have been interesting news, that it is made of similar products of earth and the moon and it came from the inner solar system is about as easy a conclusion as one could come by.
