DNA molecules can unite in only so many ways. Actually, the number of ways is 10 to the 2,400,000,000th power. So the chances of there being someone with exactly the same makeup as you is 10 to the power of 2.4 billion (that's 10 with 2.4 billion zeroes following it. Someone calculated that to write this number out longhand with each zero being one inch wide it would be 37,000 miles long! It's very hard to put figures like this in perspective. But physicists have estimated that the total number of particles in the whole universe is about 10 to the power of 76. Ouch, my brain hurts!
We've all heard it said that we are one in a million... well, that's just a slight understatement!
