(Phys.org)—Recent gravitational wave detections have allowed physicists to confirm with greater and greater precision what Einstein predicted over 100 years ago in the theory of general relativity: that gravity does not ...
There's a handy trick for reading station signs that otherwise fly past in a blur as you travel in a high-speed train. Look at one side of the window and then immediately at the other side of the window. When you change your ...

When an airplane begins to move faster than the speed of sound, it creates a shockwave that produces a well-known "boom" of sound. Now, researchers at MIT and elsewhere have discovered a similar process in a sheet of graphene, ...
