These Incredible Gravity Defying Things Will Make You Look Twice

Yet if they are so common in the universe, why haven't physicists found them? "We can detect massless particles such as photons just fine, but gravitons elude us because they interact so weakly with matter," said Michael Turner, a cosmologist at the University of Chicago. "We simply don't know how to detect one." Turner, however, isn't despondent about humanity's quest for gravitons. He thinks we'll eventually ensnare a few of the pesky particles hiding in the shadows of more easily detected particles.​​​​​​​
