The Great Void
How real is Laura Mersini-Houghton a physics professor from University of North Carolina theory about the Great Void?
Speaking of distance in the form of light years is often times hard for the average person to wrap their minds around. A light year, however, is a measure of distance, and it represents how far light can travel in one year. The velocity of light is approximately 300,000 kilometers each second! That is a staggering number, but that being said, in one year, light can travel about 10 trillion kilometers. Kilometers are an adequate measure of what goes on here on earth, but they fast become near useless when we are confronted with explaining the vastness of the galaxy. For this reason, light year becomes a useful measure when the numbers become just too big to write. For example, the distance to the next big galaxy, Andromeda, is 21 quintillion kilometers. …
