Are there more stars in space than there are grains of sand on earth?
So how many grains of sand are there in the world? You could start off by trying to guess how many grains of sand there are in a spoon of sand. Use a magnifying glass to count how many grains fit in a small section. Then, count how many of those sections fit in your spoon. Multiply the two numbers together to get an estimate. “Using this same principle, plus some additional information, mathematicians at the University of Hawaii tried to guess how many grains of sand are on the world’s beaches. They came up with 7,500,000,000,000,000,000, or seven quintillion five quadrillion grains of sand.” How many grains of sand are in the world? http://www.miamisci.org/tripod/whysand.html The calculation is detailed here: http://www.hawaii.edu/suremath/jsand.html That number is 7.5 x 10^18 or 7.5 billion billion. How many stars, galaxies, clusters, QSO’s etc. in the Universe? http://www.faqs.org/faqs/astronomy/faq/part8/section-3.html “To get the total stellar population in the Milky Way [that is,
