Astrophysicists have believed that half the elements which are heavier than iron were formed in gigantic star explosions, known as supernovas. However, there is one little snag with this theory: Astrophysicists have huge problems to make computer simulations of a supernova. âA supernova is extremely complicated.

History records the largest Amur tiger as weighing in at 1,000 pounds, though this was an extreme case in a captive cat and they normally outgrow their wild cousins. A wild Amur would be lucky to reach 650 to 675 pounds. In length, thesetigerscan reach 13 feet, between the pegs, but this is the exception, not the rule. Lengths of 8-10 feet are more usual.
