Interesting, I was though asking specifically 10^1,000,000,000,000 years from now.
If the proton does not decay, there may still be some neutron stars and black dwarfs left in the universe at that time. In about 10^10^76 years though, they may quantum tunnel into black holes which would eventually evaporate, leaving a similar end state to that there would be if the proton did decay (every fundamental particle in existence being alone in it's observable universe). It would just take longer for the universe to get there than if the proton did decay.
