I would like to understand the science behind how bacteria can live under the 50 gigapascals of pressure that one would find in the base of a skyscraper.
My intuitions currently tell me that finding life underneath such mechanical stress is comparable to finding life inside the lava of a volcano or on the surface of the sun.
- YayamiOmate 7y agoWell, there are bateria living on chemical energy deep down in the oceans near volcanoes, that's not far from your example.
- Gibbon1 7y agoThere are actually bacteria living in rocks thousands of feet below the surface.

I guess you will need to rethink about the order or magnitude of the pressure you cited: https://en.wikipedia.org/wiki/Orders_of_magnitude_(pressure) https://en.wikipedia.org/wiki/Orders_of_magnitude_(pressure) Easy comparison terms are pressure to create artificial diamonds 18 GPa, pressure at the bottom of the Mariana Trench 110 MPa. Compression resistance of concrete is between 20 and 80 MPa: https://en.wikipedia.org/wiki/Compressive_strength https://en.wikipedia.org/wiki/Compressive_strength Where 20 is "common" concrete, 30-50 is typical reinforced concrete, anything above is specisl, high strength concrete.
