"Is that a Flip Wilson joke?"

The Milky Way, just like every galaxy in the cosmos, moves. While everything in the universe is constantly moving because the universe itself is expanding, since the 1970s astronomers have known of an additional motion, called peculiar velocity. This is a different sort of flow that we seem to be caught in. The Local Group of galaxies — a collection that includes the Milky Way, Andromeda and a few dozen smaller galactic companions — moves at about 600 kilometers per second with respect to the leftover radiation from the Big Bang.
Over the past few decades, astronomers have tallied up all the things that could be pulling and pushing on the Local Group — nearby galaxy clusters, superclusters, walls of clusters and cosmic voids that exert a non-negligible gravitational pull on our own neighborhood.
The biggest tugboat is the Shapley Supercluster, a behemoth of 50 million billion solar masses that resides about 500 million light years away from Earth (and not too far away in the sky from the Vela Supercluster). It accounts for between a quarter and half of the Local Group’s peculiar velocity.
The remaining motion can’t be accounted for by structures astronomers have already found. So astronomers keep looking farther out into the universe, tallying increasingly distant objects that contribute to the net gravitational pull on the Milky Way. Gravitational pull decreases with increasing distance, but the effect is partly offset by the increasing size of these structures. “As the maps have gone outward,” said Mike Hudson, a cosmologist at the University of Waterloo in Canada, “people continue to identify bigger and bigger things at the edge of the survey.

“Called peculiar velocity”
That’s what I told that policeman.
“Do you know how fast you were going?”
“No. I’m suffering an episode of peculiar velocity.”
Cost me $250.
That theory has been falsified, but establishment cosmologists refuse to even look at the evidence.
Search the term, 'electric universe' for more info.
The Shapley Supercluster itself (along with everything observed to date in the Universe) is moving toward some other object still more massive and sometimes refereed to as the Great Attractor in Sagittarius.
Some bad news for you folks. Our galaxy, The Milky Way Galaxy is heading straight for The Andromeda Galaxy, actually the two are on a collision course, at a speed of 400.000 mph. The good news is we’re 2 million, 300,000 light years apart.( a single light year, the distance light travels in a vacuum in one year is is around six trillion miles). But we’ve got some time yet. So if there is anything you’ve wanted to do or needed to get done, you’ve still got some time to do it. And now back to our regular programming.
If I recollect correctly, ludicrous speed is the magnitude of peculiar velocity.
No stars dude - GALAXIES !
Even more awesome, what was discovered was a plethora of galaxies.
Fascinating article... Thanks.

My pleasure.
