Strange lumps in the depths of the Earth's mantle are remnants of the planet from the collision that also created the moon

The new research from Calcutta suggests that remnants of that ancient planet known as Theia are still inside the Earth and explain the origin of the "lumps" near the core-mantle boundary. Other remnants of it coalesced to form the moon

Things that Yorams know: why does the earth rotate like shawarma?

What would happen if the earth did not rotate on a north-south axis (like a shawarma skewer) but on some axis on the equator?

Does the geological clock based on the half-life of radioactive materials need to be recalibrated?

Are events in the distant past, such as the extinction of the dinosaurs, about ten percent closer in time to us? And how does it relate to solar flares? This is according to ongoing research by a group headed by Prof. Yitzhak Orion from Ben Gurion University. In an interview with the Hidan site, Prof. Orion also explains the role of the neutrino particle in the phenomenon

Things that Yaorim know: where does the compass needle point?

Niv asks: Why does the compass point north if the dynamo that flows under the surface of the ground, under the entire earth, is the one that creates the magnetism?
Is it possible to reconstruct the Earth's magnetic history using glacier samples?

The magnetic field and electric currents in and around the Earth produce complex forces that have a huge impact on our day-to-day lives. One can imagine the field as a giant bubble, protecting us from space radiation and charged particles with which solar winds bombard the earth. Credit: ESA/ATG medialab

One of the 60 micrometeorites found in a 2.7 billion year old limestone from the Pilbara region of Western Australia. These micrometeorites are composed of iron oxides formed when meteoric iron dust particles oxidized as they traversed Earth's atmosphere, revealing that the upper atmosphere was surprisingly rich in oxygen.Credit: Andrew Tomkins
