What if the Earth collapses to a black hole, instantaneously?
JupyterLab notebook, view as:
- PDF document without code <-- easiest to read
- PDF document showing code <-- shows all work
<-- in the cloud, editable and interactive
Using the GColab link lets you run the IPython code in the cloud; you're welcome to change my starting values and play around with the results. You can even change my equations, if you wish. Both diagrams are auto-generated and will adjust to your changes.
This was for fun, and was inspired by a cool podcast scenario:
You’re standing on the Earth's equator, when it suddenly collapses to a black hole, out from under you. Do you fall into the resulting black hole, the size of a peanut?
- The Makefile is currently used to generate the two output PDFs automagically.
- I use the fantastic direnv package for a local Python3 env. See .envrc.
- The needed pip3 packages can then be loaded using requirements.in.
- gh-pages or similar
- installation instructions on iPad, Mac/Linux/Win
I also need to update my conclusions for a likely limit to black hole angular momentum. Yes, it seems likely that the Earth has way too much rotational angular momentum to collapse ALL of its mass into a black hole.
