Largest structure in universe found

A quasar cluster about 4 billion light years wide. For comparison the Milky Way is about 100,000 light years wide.

Mind blowing.

It is mind-blowing, and these extreme distances that we're talking about are why interstellar space travel, or really much of any space travel, is really so very far fetched. At least in the present.

Unless we can find a way to travel using black holes or something similar.

You mean wormholes, which probably wouldn't work as proposed. Much less be stable. Because you need something supermassive enough to bend space so that you can walk across the street from Pittsburgh to Chicago. It's just sci-fi. Somebody played with high level esoteric math until they produced 50 lines of equations that suggested that a wormhole was theoretically possible. Now the reality is a little different.
