[1] [2] Collision simulations support the idea that the large low-shear-velocity provinces in the lower mantle may be remnants of Theia. [3] [4] Theia is hypothesized to have been about the size of Mars, and may have formed in the outer Solar System and provided much of Earth's water, though this is debated. [5]
The researchers ran computer simulations examining the impact event, geophysical properties of the material that likely made up Theia and the evolution of Earth's mantle - the broadest of the ...
Theia, an ancient planet, collided with Earth to form the moon, scientists believe. A new study suggests Theia could have also formed mysterious blobs called large low-velocity provinces, or LLVPs.
If a separate proto-planet Theia had existed, it probably would have had a different oxygen isotopic signature than Earth, as would the ejected mixed material. [51] The Moon's titanium isotope ratio (50 Ti/ 47 Ti) appears so close to Earth's (within 4 ppm), that little if any of the colliding body's mass could likely have been part of the Moon ...
4.5 billion years ago, Earth experienced a cataclysmic rendezvous with a planet named Theia. Evidence of the impact is still buried deep within the Earth. 2% of Earth's Mass May Be Debris From the ...
Early accounts gave her a primal origin, said to be the eldest daughter of Gaia (Earth) and Uranus (Sky). [4] She is thus the sister of the Titans (Oceanus, Crius, Hyperion, Iapetus, Coeus, Themis, Rhea, Phoebe, Tethys, Mnemosyne, Cronus, and sometimes of Dione), the Cyclopes, the Hecatoncheires, the Giants, the Meliae, the Erinyes, and is the half-sister of Aphrodite (in some versions ...

First proposed in 2010 [1] as an eon, it is named after Chaos, the primeval void in Greek mythology. This proposal defines the Chaotian eon as a Solar System-wide time between the initiation of planetary formation and the hypothesised collision of the trojan dwarf planet Theia with the proto-Earth.
