Currently astronomy is limited by our visibility horizon to about 14 billion light years away since we are limited by the speed o of light.
But could dark energy not only cause FTL (= faster than light) expansion but actually travel faster than light speed?
If so, could we some day have dark energy telescopes that would allow us to observe many times further than our visibility horizon allows us to observe?
After all, we have all sorts of telescopes using all sorts of energy to make observations. Why not dark energy as well?
