Our leading theory of dark matter may be wrong, huge new gravity study hints

A deep space image shows the phenomenon of gravitational lensing, with a circular ring of light bubbled around a golden star in the center of the image. The rest of the image seems bulged into a fish-eye circular shape due to the lensing.

Physicists' top theory about the nature of the universe may be wrong, a new study of strangely warped light suggests.

The new research looked into three leading theories of dark matter, the invisible stuff that makes up most of the universe and provides structure to most galaxies, though we still don't know exactly what it is.
