Just for fun...

Number of stars believed to exist in known universe:
70,000,000,000,000,000,000,000

Number of *drops* of water estimated to be the world's oceans (U.S. Navy):
222,000,000,000,000,000,000,000,000

Number of *unique* UUIDs:
340,282,366,920,938,463,463,374,607,431,768,211,456

So, your chances of a collision with *hundreds* of *billions* of truly
random UUIDs is inconceivably low.

The only thing you really have to worry about are humans and the code
they write ;)


Best,
