What toppings? Are we talking fresh Moz? White sauce? This is very important.
A pizza oven is about 450 C, so I’ll figure it out based on this graph of the temperature in the Earth by depth.
0 to 500 C = 80 px
6.25 C per pixel
450/6.25 = 72 px
0 to 100 km = 54 px
1.85 km per pixel
Line y coordinate at 72 px x coordinate = 9 px
9*1.85 = ~17 km
The deepest hole we’ve ever actually drilled is the Kola superdeep borehole, which is a bit over 12 km deep. This is a fair bit short of our ideal pizza oven temperature, but it did see temperatures of 180 C, which is certainly enough to cook a pizza.
The geothermal gradient is different at different parts of the earth. You can probably bake a pizza at much shallower depths at the mid ocean ridge, near a volcano, or even at an active orogeny.
Yeah. There is also likely a position in the earth where its possible to cook a human perfectly by getting them to bring a pizza there.
There must be infinitely many such positions if there is one
