Sorry, Kim K ... No One Can Break the Internet!

No one knows the Internet like Vint Cerf ... 'cause he invented the freakin' thing, and he says it'll take more than Kim Kardashian's naked ass to take down his baby.

We were hoping to get a funny answer from one of the "fathers of the Internet" when we saw him in D.C. -- but he took our photog's question about Kim K's "break the internet" campaign ... way too literally. Scientists do that sometimes.

Anyway, sounds like Cerf is throwing down the gauntlet in this clip -- bring it on Kim K., Miley Cyrus, Caitlyn Jenner, cats everywhere ...
