"But not if our Universe is accelerating. If something is receding from us right now at more than 299,792.458 km/s—faster than light speed—and it’s accelerating too, how could anything reach it?"
Isn't c the upper bound of speed in our universe?
is the upper bound of acceleration through space. Think of it this way. acceleration of a point through the 3d graph of space IS limited to C. But the lines of the graph itself that define the 3d location of things in space are accelerating from each other... the farther they are from each other the farther they recede. There is no limit to that recessional velocity. You will get to a point where acceleration being fixed simply can't keep up with the recession, so you'll never reach those parts., nor will light from those parts reach your position. Vice versa applies here. We're receding at a speed greater than light from those areas. We're not feeling relativity effects because we're moving WITH OUR SPACE
I'm surprised that no one has yet mentioned the ultimate consequence of this recessional acceleration. Eventually the regions where this shows as an effect become smaller and smaller. Galaxy super clusters, then clusters, then galaxies fly apart, and that's when the effect really accelerates, shortly there after, solar systems, stars, planets, and ultimately even the atoms that once composed you and I fly apart as even as the recessional lines of space, accelerated by dark energy rip our observable universe down to a literal NOTHING. So the other end of the Big Bang becomes a Big Rip. Look it up.
