Why Is Earth’s Core Younger Than Its Surface?

parts of the world, Although it may not seem logical at first that they have different ages from each other, Scientists and a theoretical physicist have some opinions on this point.

What about the core of the earth? How can it be younger than its surface?

About 4.6 billion years ago, on the Earth’s surface, a hot dust cloud orbiting the Sun coalesced and began to cool.

Thus, heavier elements form the center of the Earth, while lighter elements form the center of the Earth. mantle and the thin crust layer formed on the surface created.

All of these are the world’s accumulated more matter in the intervening years caused. Additionally, according to the researchers, a potential collision with Theia, a Mars-sized planet that likely formed the Moon, was also involved.

So it has been confirmed that the core is younger than expected.

Also in the 1960s, theoretical physicist Richard Feinman argued that, according to general relativity, gravity has time-dilating effects. The center of the Earth is 1 or 2 days younger than the surface He stated that it was.

But again, objects with more mass have more gravity and The Earth’s heavy core consists of a much denser iron-nickel alloy than the surface Turns out Fineman was wrong.

According to scientists’ calculations, this period is actually It was 2.5 years, not 1-2 days. In this regard, it was also determined that the surface of the Sun is approximately 40,000 years older than its center.
