A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

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.

i doubt i would have time for cooking at an active orogeny.
