I wanted to find out the difference between a supernova, and the energy it would take to blow up the Solar System.
This guy:

Says it would take the equiv of 5.09x 10^37 Tons of TNT to blow up the Solar System
Wikipedia says a Super Nova is 1x10^28 Tons of tnt.
So the Super Nova would be much smaller.
Then I did my own calcs ( all numbers are J )
I took the gravitational binding energy of the Sun 6.9 x 10^41
Then of the planets, For the planets I took earth's:
binding energy of Earth = 2 x 10^32
Multiplied it by 9 for each planet , and then doubled that number for a decent estimate:
So : 36 x 10 ^32
so Binding energy of sun + 36 x 10^32
and I got
6.900000036 x 10^41
As the energy needed to destroy the SS by over coming the binding energy
( for this whole thing I am ignoring distance from the cause and such, assume they are all right near each other )
And the energy of a Supernova is 10^44
So with my way of doing things, and the others guys both contridict, Mine shows that a SN would be about 200x a Solar systems destruction.
And the tnt Guy's seems to show a Supernova is MUCH less than a Solar System level explosion
Thank you for the help!
