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 Groups peculiar velocity.
The remaining motion cant 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.

600 km/s could get you a speeding ticket in most galaxies.
I knew it!! Clearly we have a case of galactic climate change.

(KJV)
9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light;
“I knew it!! Clearly we have a case of galactic climate change.”
So, you’ve finally FLIPPED huh,Wilson....LOL...

Uh Huh- tell that to God when ya see him- He’ll likely be unimpressed with your conclusions
Astronomers generally stay away from the Zone of Avoidance. When one astronomer didnt, she found a giant cosmic structure that could help explain why our galaxy moves so fast.

Now there's a paradox that's sure to swallow up entire galaxies of established wisdom.
Big Bang?
Wasn’t that dismissed a few weeks ago by another scientific/astronomical group?
Ping
No problem. It's nothing that some more taxes and laws won't fix.
There was no Big Bang.....
They recently pointed the Hubble at an area where it appeared to have no stars as it was referred to aa large black void. Well they found millions of stars,.opps
>>Shapley Supercluster
Hopefully Al Frankin won’t be allowed near it while it’s asleep.
More taxes should indeed fix this case of galactic climate change. But are the Klingons and Romulans paying their fair share?
LOL!! ... and very perceptive as "galactic warming" wouldn't quite work now, would it?
I would call it galactic warmingcoolingorsomething but it is too long. So I went with climate change.
I’m sure the Klingons are, but the Romulans? If they were, I’d be more surprised than anyone!
CA....
Thanks stockpirate. Also going to ping the APoD list, bound to be of interest.
Life has such odd ironies, some of which are just artifacts of insane politics.
