Math Problem Statement
It is believed that the universe began with a big bang about 16 billion years ago. Neglecting the expansion of the universe, we can reason that the most distant objects observable are no further than the distance light could have traveled in 1.6 × 1010 years. If the speed of light is 2.99792 × 108 m/s, what is the maximum possible radius of the observable universe? Answer in units of m.
