<div>The fact that the universe has a finite life span might
be inherently related - i.e., it makes no sense to talk
about accelerating over infinite time, because infinite
time never exists. <br>

How do you know it has a finite life span? In fact, current
cosmological models suggest expansion forever.<br>
<br>
I think it is an open question whether infinite anything can exist.
I have not seen IMHO any sufficiently convincing arguments for or
against it.<br>
