Something Strange Punched a Hole in the Milky Way. But What Exactly Is It?

There's a "dark impactor" blasting holes in our galaxy.

Stellar streams are lines of stars moving together across galaxies, often originating in smaller blobs of stars that collided with the galaxy in question.

Under normal conditions, the stream should be more or less a single line, stretched out by our galaxy's gravity, she said in her presentation. Astronomers would expect a single gap in the stream, at the point where the original globular cluster was before its stars drifted away in two directions. But Bonaca showed that GD-1 has a second gap. And that gap has a ragged edge — a region Bonaca called GD-1's "spur"... GD-1, it seems, was hit with that unseen bullet

This dense ball of unseen something plunging through our Milky Way offers physicists a new scrap of evidence that dark matter might be real. And it would suggest that dark matter is really "clumpy," as most theories about its behavior predict.

If dark matter is "clumpy," then it's concentrated in irregular chunks distributed roughly across galaxies — much like the luminous matter we see concentrated in stars and nebulae. Some alternative theories, including theories that suggest dark matter doesn't exist at all, ... and would have the effects of dark matter distributed smoothly across galaxies.

So far, Bonaca's discovery is one of a kind, so new that it hasn't yet been published in a peer-reviewed journal...

...she relied on data from the Gaia mission, an European Space Agency program to map billions of stars in our galaxy and their movements across the sky. It formed the best existing catalog of the stars that seem to be part of GD-1.

Rather than dark matter - I think it may have been a rogue black hole.

Which came first ?

Matter OR Space ?

If Time is only a measure of events, can there be time before matter came to be?

Ain’t words fun !!

There had to be space for things to occur in, initiating time. So space came first, then matter.

And it’s something quite peculiar...
Something shimmering, and white?

Added bonus that it’s one of those rare songs that even a novice (such as myself) can easily play on an acoustic, and do a somewhat passable rendition of (only five, simple chords).

If’n matter had failed to show up (From where/whatever)who/what would define ‘space’ ? Who / what would say -—> Space is empty ?

Words are fun !

Quantum foam throwing up virtual particles,
a feature of space, will fill in the missing matter.

Physics is fun!

That song reminds me of when I first moved to the DFW area, they played a free concert at The West End.

Apparently "another way".

People of Earth, your attention, please. This is Prostetnic Vogon Jeltz of the Galactic Hyperspace Planning Council. As you will no doubt be aware, the plans for development of the outlying regions of the Galaxy require the building of a hyperspatial express route through your star system. And regrettably, your planet is one of those scheduled for demolition. The process will take slightly less than two of your Earth minutes. Thank you.

"Something Strange Punched a Hole in the Milky Way."

Take a photograph of it and return it to the store ASAP... Then call a lawyer about your "milky way" deficiency post-traumatic stress......
