Size of the Halo Earth (To a downplayer)

Okay as we all know, Covenant Ships are only building level going by this scene



Since Halo sucks, I will assume it is only the minimum of building level, or .25 tons of TNT

Also, since cinematic timing is BS, I will assume it took the length of the whole mission to destroy it. Or 5 minutes (That is how long I could stand the game)

So it has a power output of 3,486,666.67 watts.

Now it takes 30 years for the Covenant to glass the surface of the Earth. As a highball I will assume it meant the hole crust. It also said it needed a full fleet, since 500 ships is wank. I will assume it took the amount of ships of the entire Covenant. Or only 3000.

I get 9.90256338e18 joules to do that.

Now melting it would be wanking, I will assume they only pulverized it.

Thus I only get 4.59835773e13 liters.

The crust is 1% of the Earth. So the entire Earth is 4.59835773e15 liters.

I only get 12.8 Miles, which is very consistent.

As you see, Halo's Earth is only the size of an island.
