SOLUTION: According to the Einstein�s Theory of Relativity, nothing in the universe as we presently know it can exceed the speed of light; in a sense, it is the ultimate cosmic speed limit.

Question 323000: According to the Einstein�s Theory of Relativity, nothing in the universe as we presently know it can exceed the speed of light; in a sense, it is the ultimate cosmic speed limit. Speed of light in vacuum is 300,000 kilometers/second or 671,080,888 miles/hour! Take a moment and think about this tremendously high speed; it is extremely fast; faster than a speeding bullet (speed of a rifle bullet is in the range 400 to 3,350 miles/hour). a) Show the speed of light in scientific notation in units of miles/hr. b) Given that Moon on average is 240,000 miles away from where you are standing on Earth, how long does it take a light ray to travel from the Earth to the Moon?
