We can see things moving faster than light

TL;DR I think there's a misconception that comes because they don't clarify that the hubble parameter is actually decreasing

Sorry, I'm not sure if what I wrote below is actually correct

I think the hubble parameter is a measure of the rate at which a fixed unit of space is expanding, and it is decreasing, that's why the Hubble sphere expands

When they say that "space expansion is accelerating", they are not talking about an hypothetical fixed unit of space, they are talking about all of space, a.k.a the universe, another way to say it, the space created per second in the whole universe is accelerating, and that makes totally sense, the more space there is the more is going to be created, in other words, as long as there's some space been created per second per unit of space, the universe's *volume* will accelerate, but not the radius (assuming it's finite)

So the rate at which space is being created inside our *current* Hubble sphere, is decreasing over time, hence the expansion that's happening in a straight line is slowing, light from farther away will be able to reach to us and thus the hubble sphere expands
