That expansion at an accelerated rate - that's just so eerie when you think about it. The furthest objects we can see right now will slip away out of reach forever for the next generation, and so on. It's crazy to think that as time goes on, there will be less and less universe to observe.
That's something really interesting, though. When we look at distant objects, we aren't limited by the distance they're at right now. We're limited by the distance they were at when they emitted the light.
So the observable universe is still growing because the edge of that bubble is such a long time ago that everything was still much closer together.
But the light that reaches us is constantly getting stretched (red-shifted), so I'm not sure that our bubble is growing. Instead when they're stretched too thin, we won't be able to see it. I'm not 100% sure on the expansion rate of the universe and the pace of red shifting. Also, eventually all the galaxies are expected to be pushed so far away from each other due to the pressures exerted by Dark Energy, that soon we'll only be able to see just the stars of our Milky Way.
One of the weirdest facts. One that really makes you feel so small.
