>except it has momentum, can create independent forces, does affect the gravitational acceleration of objects near it proportional to said lights magnitude, has varying levels of luminosity again proportional to its magnitude, allows the formation of black holes to even be defined and literally cannot travel at its maximum velocity when not in a vacuum
