How do we know that there isn't something else in space that bends light?
Water bends light, and in the right conditions you can't visually prove that it is in between the eye and the object.
Is it possible that space is filled with something which isn't percieved by material beings and their material instruments?
While an absense of physical evidence isn't a licence for the imagination, it is presumptuous to say that what is observable is the only truth.
