Deep beneath our feet — 2,900 km down — lies a continent-sized mystery.
A region where seismic waves slow down,
where the chemistry shifts,
and where Earth’s deepest secrets seem to gather.

In 2023, a groundbreaking study proposed a stunning idea:
this vast hidden layer may be the last surviving fragment
of an ancient planet — Theia,
the world that struck the proto-Earth 4.5 billion years ago
and gave birth to the Moon.

If true,
then an entire lost planet isn’t drifting in space…
it is buried inside Earth itself.

A vanished world.
A mysterious mantle structure.
A collision that shaped the oceans, the seasons, and life itself.

Today’s topic:
Theia — the ancient planet that may still be inside Earth,
and the deep-Earth structures that rewrite our understanding of the Solar System.
