500,000,000,000,000,000,000,000 = 5 x 1023 = 500 sextillion.
This is just shy of the number of molecules in one mole of any substance (6.022×1023 = Avogadro's number).
This number also happens to be in the ballpark of the diameter, in miles, of the observable universe, based on latest astronomic research (90 billion light years, multiplied by 6 trillion miles per year).

Sharks are known to swim at speeds ranging from about 1.5 mph to 60 mph, depending on the species. Most sharks typically swim at an average speed of around 5 mph to 10 mph. The shortfin mako shark is one of the fastest shark species, capable of reaching speeds up to 60 mph in short bursts.
