Try to fathom a cosmos that is so immense that it takes a
beam of light fifteen billion years to travel from one end to the other. Who
can fathom fifteen billion years? Now try to think of the size of the universe
by calculating the speed of light at 186,000 miles per second, 11,160,000 miles
per minute, 669,600,000 miles per hour, 16,070,400,000 miles per day, 5,869,713,600,000
miles per year. Now all you have to do is multiply that by 15,000,000,000.
That’s the size of the universe. We literally do not have words to express that
number. It is incomprehensible and ineffible.
