Scientists Hunt for Smallest Objects in Existence

Superstring theory could help us measure one

(Newser) - The tiniest thing in the universe is not a grain of sand, as people once thought, nor a proton or neutron, or even a quark or electron—as small as they all are. In fact, experts today balk at naming any point-like object "the smallest" because of a theoretical... More »

Gravity Doesn't Exist: Physics Prof

String theorist shakes up 300 years of science

(Newser) - Anyone who's ever seen a ball drop knows it's obvious that gravity exists—right? Not so fast, says a prominent string theorist who has called into question 300 years of science with a new paper arguing that gravity is merely an illusion. Dutch physicist Erik Verlinde says gravity is not... More »
