We Might be able to Find Evidence for Modified Gravity…in the Earth - by PaulMattSutter
But we know the general relativity is incomplete. We know that it breaks down in the centers of black holes and at the beginning of the universe. So we know we do not yet have the full story of gravity in our hands. Motivated by this, many people over the decades have proposed theories of modified gravity, which constitute a set of extensions and refinements to Einstein’s original model..
The more ways we can develop to probe modified gravity the better. And so a team of researchers have found that weto test various modified theories of gravity. We can instead look down into the Earth. They discovered that under modified gravity, seismic waves travel through the Earth at different rates and in different ways.
Since we know so many properties of the Earth so well, like its mass and its moment of inertia, we can turn this knowledge around to use seismic data to constrain modified gravity theories. So far the data do not suggest any need for a deviation from Einstein’s original work. But the more tools we develop, and the more ways we can search, the better.
