Article I, Section 8, of the Constitution, which enumerates the powers of Congress and provides Congress with the authority to make all laws necessary and proper to carry them out; also referred to as the elastic clause.
There is an exact numerical answer to this question. By definition, 1 light year is exactly 9,460,730,472,580,800 meters. By definition, 1 mile is exactly 1,609.344 meters. So, 1 light year is exactly 5,878,625,373,183 and 849/1397 miles, by definition.
There are 186282 miles in a light-second. 3600 seconds in an hour, 24 hours in a day, and 365 days in a year (the year used to define the light-year)â¦ so there are: 186282x3600x24x365x8 = [you do the math] billion miles in eight-billion light years.
