This week on Spacetime, we take a detour into how geometry works in spacetime. Last time we talked about what curvature means, looked at geodesics, great circles on spheres, and tried to understand ...

When white light is passed through a prism, the rainbow on the other side reveals a rich palette of colors. Theorists have shown that in models of the Universe using any of the quantum theories of ...

Just as white light is made up of various wavelengths of light, so too is spacetime composed of various versions of spacetime. Michelle Starr is CNET's science editor, and she hopes to get you as ...
