How would you approach getting the state of the universe in the smallest possible compression?

Something like H265 I guess.

It depends on what the representation of the state of the universe would look like I guess, but assuming something like a 3D matrix of values that changes over time, where certain values are more common, where regions tend to have similar values, I guess it would be a similar problem to lossless compression of 3D videos, just at a larger scale.

Number of atoms in our Sun - 10^57.... I bring it up when talking about our possible simulation - I think that it would be approximated rather than having 10^57 atoms explicitly simulated....

I think it's better to start off with trying to save the state of the Sun.... the width of the Sun is about 1,300,000,000 meters. Planck length is 1.6x10^-35 meters... which is about 10^44 Planck lengths wide.... (10^44)^3 = 10^132 Planck spots (in a cubic Sun).

I'm not sure how many bits it would take to store a number between 0 and 10^132... (or 3 dimensions of 10^44)?

But anyway you'd need to multiply that number by 10^57 to work out the memory requirement for storing a snapshot of our Sun....
