1000 times bigger than originally thought? And they say 15 meters in diameters? That would mean they originally thought it was 1.5 cm big. It seems
they where originally very dumb, or something doesn´t smell right here.
Yeah - you math!
1000 times the mass is not 1000 times the diameter - volume increases with the cube of the diameter (radius x 2) - so it is about 10 times the
A 1.5m diameter sphere has a volume of about 1.8 cubic meters, and I saw somewher the figure of 4.25 t/m^3 for the material, so that's about 7.5
Make the sphere 1.7m and you get 11 tonnes - yep - just a little increase in diameter - 0.2m, about 8", adds almost 3.5 tonnes!! (unless my math has
suddently gone to carp!!
