In the quest to understand gravitational pull, researchers attempt to unlock a less theoretical and more quantum-based, or mathematical, explanation based on interactions of what it is exactly. One of the ways they are looking to understand how gravity and gravitational pulls work, is to see how it comes to violate laws by which they are defined. Let's try this as background. True to the pursuit of scientific knowledge, researchers look to aberrations and not constants. They look for a break in patterns to try to understand more of the picture.
Gravity is no exception.
Ubem is an author of a paper in this week's issue of the journal Nature, looking at the effect of the solar eclipse on atomic clocks. To better understand it and be able to put it in a quantum form scientists look for fluctuations in the laws of gravity to figure out how it can be explained. Solar eclipses have been associated with changes in gravitational pull and have been measured using gravimeters. So the overall pull would be less. To answer that question NASA researchers suggested that facilities located around the globe examine a solar eclipse, this past one in August, and look for quantifiable means to see if there was a way of seeing how gravity may be altered and what effects it may have.
