What nonsense did you believe in as a kid?Ever thought that you could get flushed down the loo? That girls wee out their bottoms? Or that bumming means two men rubbing their bums together? Tell us about your childhood misconceptions. Thanks to Joefish for the suggestion.

Found some physicsKinetic energy = 1/2 mass x velocity²
Kinetic energy = 1/2 (5.9736×10^24 kg) (12300 m/s)²
Kinetic energy = 4.52x10^32 J
In terms of Megatons of TNT, that's about 1.08x10^17 Megatons. The biggest nuclear weapon ever designed had a maximum theoretical yield of 100 Megatons, so it would take about 1 QUADRILLION bombs. That's more than one hundred fifty thousand 100-Megaton bombs for every man, woman, and child alive today. Needless to say, the world's nuclear arsenal isn't anywhere near that size. Even if we DID have that many bombs, and if we COULD get them all into one place and cause them to blow up perfectly (without having ANY of them vaporized before they detonate...a technical impossibility), you'd still need to have ALL of their energy go into moving the Earth. In reality, that simply won't happen. That 1 quadrillion bombs is a very, very low estimate of how much firepower you would actually need to knock the Earth out of the solar system.
