I think it would be helpful to measure gravity so we know how it affects animals and plants and planes and spaceships and cars. I think the most important type of information it gives us is just like making sure people are safe and that there’s nothing we are going on or that the gravity increases at a rate or if it decreases just so we know how to handle it in the future and I think that information would be useful so we don’t die.
