The rock, before it was metamorphized, was a granitoid that formed 4.03 billion years ago. This age is based on radiometric dating of zircon crystals at 4.031x10 years. The Acasta Gneiss is important in establishing the early history of the continental crust.

Origin of water on Earth
The origin of water on Earth is only partly known. Life as we know it depends on water, and most types of life started in the seas. Earth is the only planet known with liquid water on its surface. The water on Earth may have come from the Solar System as it formed, or it may have formed on Earth. Both are possible.
Our planet is in the habitable zone, not so far out that all water freezes, and not so close to the Sun that all water evaporates into space. This is why liquid water, necessary for life as we know it, continues to exist on the surface of Earth.
It was long thought that Earth’s water did not come from the planet’s region of the protoplanetary disk. Instead, it was thought water must have been delivered to Earth from the outer Solar System later in its history. However, recent research suggests that hydrogen inside the Earth played a role in the formation of the ocean. The two ideas are not mutually exclusive: there is evidence water was delivered to Earth by impacts from icy planetesimals similar in composition to asteroids in the outer edges of the asteroid belt.
One problem, not yet resolved, is that the noble gas isotope ratios of Earth's atmosphere are different from those of its mantle. This suggests they were formed from different sources.
Untriseptium
Untriseptium (), also called eka-dubnium or element 137, is a possible chemical element which has not been synthesized. Due to instabilities, it is not known if this element is possible, as the instabilities may hint that the periodic table ends soon after the island of stability at unbihexium. Its atomic number is 137 and symbol is Uts.
The name "untriseptium" is a temporary name.
It is sometimes called feynmanium (symbol Fy) because Richard Feynman noted that a simplistic interpretation of the relativistic Dirac equation runs into problems with electron orbitals at "Z" > 1/α = 137, suggesting that neutral atoms cannot exist beyond untriseptium, and that a periodic table of elements based on electron orbitals breaks down at this point. However, a more thorough analysis calculates the limit to be around element 173.
