Reminds me of a joke:

A doctor, an architect and a programmer talk about their professions. "Mine is the oldest", says the doctor, "as everybody knows God created Eve from the rib of Adam, and that's definitely a medical operation". "Right", says the architect, "but in fact architect is even older - it's definitely an architectural project to create the world from chaos". At this point programmer kicks back in the chair and gives friends a mysterious look. "Who, do you think, created the chaos?"

How is it possible to simulate an entire universe within a universe. Wouldn't you run into fundamental computational limits?

Just turn the resolution down, don't render anything smaller than the Planck length.

There are two main possibilities here, either the simulated universe is simpler (a 4d universe simulating a 3d one for example) or you only simulate consciousness and the bare minimum needed to make it believe that it's in a persistent environment.

Now I wonder if our simulation is written in Rust or a GC-ed language because It doesn't segfault.

How would you know if a segfault occurred? The simulation crashing would halt your own consciousness as well. It will probably be fine though, they started with a stress test of extreme conditions back at what we call the big bang.
