The entire universe is expected to decay at approximatly one google years(10¹⁰⁰). At this time, every planet, star, black hole, etc. will be broken down into their basic particles. These particles will never again interact with one and other. Seeing that time relative, once all of the universe's components have been broken down, time itself will be destroyed along with it. Thus leading to an occurence where a non-physical dimension is destroyed.

There is no evidence of proton decay ( yet ).

You are talking about the heat death of the Universe; the idea that at some point in the future the Universe will be in thermal equilibrium. With everything in equilibrium nothing will change, it is all 'frozen' and it will look like time no longer exists. However, time as a fourth dimension will still exists, there is no reason for such a topological change.
