Nothing can travel faster than light, so no, nothing can catch up to something traveling at the speed of light. Really though the physics says nothing can _attain_ the speed of light, so light (or some other photon) could still intercept something with mass traveling at 99.9999999% the speed of light. And that thing with mass will never reach 100% the speed of light. If you want to look deeper I suggest checking out the accelerating expansion rate of the universe, and what that means for information traveling throughout the universe over the next billions of years. Humanity is actually extremely lucky to have been born at a time when the universe was young enough to still be mostly visible. Civilizations that come about in the next 10s of billions of years might actually assume their galactic clusters are the only ones in existence (much like we thought initially until Hubble found another galaxy).
