We have 26 constants of nature whose value we need to feed into our scientific theories to get predictions about everything else.
The key question is: will their values emerge from a deeper theory or if they’re simply randomly initialised in our universe?

The fact we exist depends a lot on what value these constants take (e.g. mass of electron), so it’s hard to digest that they’re randomly initialised to lucky values.
Our universe can’t be fine tuned.
Our universe can’t be fine tuned.
But they could very well take on random values across a much bigger multiverse and hence we’ll always find them to be lucky in a universe we live in.
This possibility of multiverse is unnerving.
If all values and laws exist, physics becomes geography - the study of our region.

What will be unimaginably beautiful is if we discover that ultimately all laws and constants of our universe emerge out of a logical necessity of some sort.
