A Little Sci-Fi?

On cosmological constants……

The proposition is this:

The increasing speed of the universe's expansion will eventually approach the speed of light. Today we say there is no faster speed than the speed of light. But, just as sound cannot be heard in the same way when one travels faster than the speed of sound, since you are moving away from the sound you created faster than sound travels to reach your ears, so objects and light sources will not be able to be seen as they move beyond the speed of light and the ability of your eyes to capture and your brain to confirm the existence of that light.
Thus, dark holes and dark energy.
We will have to learn to see into what is beyond us to understand and appreciate what happens when all matter as we know it moves into the invisible dimension of what we call darkness, but which could be brighter and faster than anything we’ve known until now. Harnessing the energy in the newfound immaterial dark fabric within that dimension will one day be the lifeblood of survival for humankind. Should humankind persist so long.
