It would take about 400 nonillion (10^30) joules to destroy EarthI then asked for human translation... as you often have to do with these Braniacs...
that is 10^39 ergs -- a nova can release about 10^45 ergs, so if the solid angle subtended by the planet was greater than 1 in a million, and the energy was distributed isotropically, then a nova could do it. It is unclear though -- it depends on the properties of the nova and the planet though. A supernova could for sure. Now, how much mass would you have to convert into energy to make that happen? 10^24 kg, or very roughly 10 sextillion Harrys oops, hold on, made a mistake in that last calculation doing this in my head, because I don't have any paper in front of me 4x10^15 kg only ~20 trillion HarrysSo there you go - to destroy that planet you'd have to about 20 Trillion of Me to convert into 400 nonillion Joules... which would obliterate Earth. SO at least I know that I could contribute in some small way to the destruction of Earth if my energy was maximized with a shitload of Harry clones. Of course - Copernicus number use of me as the destructor of mankind... I think... if you saw 20 Trillion of me coming towards Earth - it'd be a lot more frightening than Romulans... right? Anyway - Here's the latest TV spot in massive beauty. Enjoy!
