It's estimated there are 10^80 atoms [1] in the visible universe, so 2^256 is definitely a huge number. I didn't realize 256 bit brute force was nigh feasible with only a solar system.

I'm a bit surprised the quantum algorithm only gives a polynomial speedup.

10^80 = (10^3)^80/3 = 1000^80/3 = 1000^26.67

2^256 = (2^10)^25.6 = 1024^25.6

These number seem very close.
