My though is that at the extremes of dimensions, space and time, things get strange and the rules of physics as we know them may not necessarily apply. We really don't know what happens to space-time in the vicinity of a black hole or at the first instant of inflation.Hi,
I am not sure it has to be comprehensible in the way that we usually need to comprehend things. In other words, it may be hard to imagine the scope of values from the very tiny to the very large, or even just the very large, but at some point in the future the presumed solution may fit in as part of another theory, and 2x the time is still 2x the time, whether it is a long or short time. That fitment may also fit into yet another discovered property that ends up solving some more practical problem such as time travel or something we don't yet have that would benefit mankind.
This might be read as the emergence of a new theory that actually helps us in some way rather than just stating a bunch of numbers for the sake of just stating numbers that sound good.
