Scientists detect gravitational waves!



 
Two naive questions from a non-physicist: (a) The fact is, the earth isn't "sitting" still in space, but actually hurtling at approximately 66,6000 MPH. So is it possible that the squeezing and stretching of the earth, which scientists observe, somehow comes from its massive speed around the sun? (b) If indeed gravitational waves behave in an undulation, then the force that presumably "holds" us to the ground should somehow undulate, too, no?
