Abstract
Objects in the universe are observed by virtue of the radiation they emit. On the basis of strongly supported theories dealing with the formation and propagation of radiation, astronomers have been able to determine distances from Earth to extremely remote segments of the universe. If one assumes that the radiation received from a distant object was generated by the object itself, and that the radiation traversed the distance between the object and Earth at a constant velocity, then the universe is at least as old as the radiation's travel time. Since radiation from some objects has taken billions of years to arrive, the universe is at least billions of years old. A common young-earth retort to the above astronomical argument for an extremely old universe is to claim that objects were created with their radiation en route to Earth. That is, both the object and the radiation en route to Earth. That is, both the object and the radiation appearing to emanate from it were created simultaneously. Although distance measurements may be accurate, no correlation exists between distance and age. Hence the universe may seem billions of years old, but its actual age is only a few thousand years.
