I was just reading this article and this sentence stood out.
https://www.bbc.co.uk/news/science-environment-49648746
“Water has been detected on other planets but they have been either too big or too hot to support life.”
The hot bit is obvious but how might a planet being too big affect its ability to support life?
In: Physics
As planets get bigger, their gravity increases substantially. At a certain point it becomes impossible for humans to survive somewhere if the gravity is too strong. Some bacteria could survive at several thousand times earth’s gravity, but we can only survive at a few times earth’s gravity.
