Light doesn't have any matter, yet it can be bent by gravity...I don't get that :-/ Can someone explain it please?!

As Einstein showed us with general relativity, gravity is curved geometry. The presence of matter/energy results curves spacetime. Particles (both massive, and then massless) then follow the shortest paths in this curved spacetime, which results in what we think of as gravity.
