Does "speed up at the beginning of their expansion" mean something different than "increase in velocity from beginning" to you? I don't know what
you're asking that I haven't already answered before you asked it. "Speed up" and "velocity increase" seem synonymous in this case.
A spring being sprung occurs usually in a second or so. And because springs are finite, yes obviously they slow down towards the end because their
momentum is being directly halted. So I was wondering if considering a spring more like the size and duration of the universe and less like the
springs that do their actions in terms of seconds. So say a spring is compressed fully, like the universe was thought to be before the big bang
(spring being sprung), and then it is sprung, and you are saying the spring consistently will increase its velocity from the moment of being sprung
until it reaches a 'tipping point' in which it begins to slow down, only because it has begun to extend to its greatest point of length, and expend
its total amount of stored energy. But it is thought the universe is not like this, because unlike the material binding of the spring as an object to
itself, the universe, or its space, does not seem to have as gravity, a strong enough material bind to itself to create a tipping point, in which it
begins decreasing momentum and becomes drawn back towards its singularity.
