'Cosmic web' observed for the first time

Scientists have revealed the first photograph of a universe-spanning network of intergalactic filaments.
Known as the cosmic web, this previously unseen highway is made up of gigantic filaments of gas (mostly hydrogen left over from the Big Bang) which bridge the void between galaxies.

It is thought that the web contains as much as 60% of all the gas in the universe.

Actually observing these filaments directly however has long proven a challenge because they are incredibly faint and easily overshadowed by the intense glow of the galaxies around them.
Now though, scientists have finally been able to piece together the first photograph of these cosmic structures converging on a distant galaxy cluster 12 billion light years away from Earth.

This feat was achieved using the Multi Unit Spectroscopic Explorer instrument on the European Southern Observatory's Very Large Telescope in Chile.

"The main obstacle to see the filaments is their faintness," said study lead author Hideki Umehata.

"To circumvent this, one can turn to a region where the filaments are much brighter than the usual case. In this work, we focus on a core of the protocluster where a number of star-bursting galaxies illuminate the filaments."

"...for the first time"??? But my avatar has been the Laniakea for years...

So I am confused. If we have the Laniakea cluster and all hurtling towards the great attractor... How do people envision that as possibly being the process of a "big bang"? It looks more like a "big drain" to me.
