From John Bailey
Max Tegmark has two suggestions for what will happen to the information in an expanding universe: either information is created, meaning we can no longer make predictions; or the quantum “grain size” of the universe – the effective “Planck length” – increases, leading to a breakdown of nuclear physics that Tegmark calls the “big snap” (24 September, p 8). Neither is acceptable.
There is, however, a third solution, which is that the universe is not a closed system, but rather is still connected to the multiverse from which new space/time is being introduced, thus allowing an increase in information without the problems Tegmark’s scenarios lead to. This would mean that the expansion of the universe would have to continue infinitely.
I suggest we all start looking for the inlet valve.
