Do you hear that? It might sound like nothing to you, but it's actually the sound of nuclear, wind and solar energy.

At EDF, we're busy generating more British

zero carbon electricity than anyone to help keep future energy

cost down for everyone and help cut UK carbon emissions to nothing. Sound good to you? Find out more about our

We are thrilled to be speaking to two guides to the formation of the moon and evidence of the

collision that happened very early in the solar system.

The article is in Nature magazine, Moon Form Impactor as a source of Earth's basal mantle anomalies.

David, you have a question for either the professor or the postdoc?

Yes, for either one so it's speculated that the

mashes into Earth proto-Earth so my question would be what percentage do you think of Thea is a remnant in Earth and

what percentage of Thea composes the moon and does that account for 100% of thea and if not where did the rest of the ago?

Chen you want to start? Okay, yeah, so according to our calculation, 10% of impactors mental may form this bas-based

of mental anomalies.

And for the moon in our model,

about 50% of the moon is also come from the impactor. So the rest of the

impacter is also come from the impacter.

Professor, about these percentages,

are they profound because you provide a video in your article that shows us what it would have looked like at the collision?

Are these numbers all consistent with that video?

50% is of the moon is earth 50% is there.

Yeah, these are from I have to give credit to Chen
