This isn't necessarily true. The article largely explains it. The interaction of particles trends to infinity faster than time. Another way to think of it... Let's say that t is trending to infinity starting from 0. There are #s that will always be larger than t. Such as (t+1)^2. One more way... Time is one dimension. The rest of space-time is 3 (at least). The size of possibilities is larger to 3 orders of magnitude. And a last way... If it's feasible that matter can expand forever, then there's no way for the particles to repeat themselves. They just keep going and going...
