lets destroy the sun

Probably a little more like Larry Niven, but your point is well taken.

Although...

I don't see it being able to be stretched any more than double per the description. Are we just extrapolating here, or are we just applying that sentence multiple times? I guess with a generous reading we could do that.

I'm applying the clause multiple times. There's nothing there that says you can -only- halve the thickness to double the area.

Strict V permissive reading of an ambiguous rule like this is up to the individual GM. I don't think my reading changes the power level of the spell at all.
