Most physicists don't understand it either. Many aren't developing new formulas because they're teaching old formulas, some are using it for weaponization and few are interested in quantifying aliens because they think Fermi and Drake already covered it in the Milky Way. However the Dill Equation can be applied to other galaxies.
Edit:// I am only amused by Dr. Michio Kaku in this era after Hawking passed away, others bore me with how far behind me they are as a citizen scientist peer reviewing them and I don't want to publish everything because it's not the complete model I'm working on.
