Let’s all whooooosh together. No REALLY whooooooooooooooosh! Think I’m being silly?? Well, rather than me going on about the silliness of the Space Lettuce today, enjoy it verbatim:
“Scientists think there’s a “dark matter hurricane” heading toward Earth. In fact, it might even be blowing through us already.
But don’t worry — it’s definitely not going to kill you. Mostly, it’s just a bunch of normal dark matter with especially good branding. And it really is headed (more or less) this way.
Here’s what’s going on: Back in 2017, astronomers spotted a stretched-out line of stars passing through our solar system’s general region of the Milky Way. The scientists named this group the “S1 stream,” identifying it as the nearest of several stellar streams moving through the galaxy. Parades of stars like these form when the Milky Way gobbles up a dwarf galaxy, stretching the smaller object out in the process. In a new paper, published Nov. 7 in the journal Physical Review D, researchers argued that S1 might be carrying with it a hefty load of dark matter from the original dwarf galaxy. And they gave that baggage the snazzy name “dark matter hurricane.”
Again, that hurricane is not going to kill you. Or blow the door off your house. But it just may cause some local spikes in dark matter, which would help researchers hunting dark matter actually find the stuff, the researchers wrote.
That’s because all galaxies, but especially dwarf galaxies, are held together by dark matter, physicists believe. So, the galaxy that was torn to shreds birthing the S1 stream likely dumped a bunch of dark matter into the stream’s path.
The problem is, no existing dark matter-detection devices have actually worked, in part because they’ve all been designed based on educated guesses as to what dark matter really is. (Scientists have very good reason to believe dark matter exists but are still guessing about its composition.)
So, the physicists behind the recent paper calculated how dense S1’s dark matter would have to be to influence signals at several soon-to-be-built dark matter detectors. When those detectors come online, scientists will know a lot more about the “hurricane” and whether it’s really blowing through our stellar neighborhood.
Until then, it’s fun to think about, isn’t it? A dense cloud of dark matter from a dead galaxy blasting invisibly through us as it follows the remaining stars on their doomed parade.

We get muddy today!! Mud floody, for sure! We get to know Martin Liedtke, find out more about the Hidden History that he has uncovered, and hear his mind get blown when he is asked if we may have all been shrunk! Martin has investigated conspiracies since 1974 and in 2015 “the penny dropped about...
Walt always says “You can’t write this shit…so THEY do.” But today we have an EXTRA special chunk-o-caca! Instead of me making fun of their ridiculous Mad Libs approach to Science writing, I’ll just put this here: “The Sun’s poles remain mysterious, but scientists are poring over past imaging data to construct artificial images of...

Turns out we live in a theory-tale world just jam-packed with thin-skinned, too-easily over-offended, ever-so-delicate snowflake-NPC sheeple-zombies. (But then, some would say I’m hyphen-happy!) Today, we get worked up over the idiocy of the easily-offended. How the HELL did we breed Humor out of humans? Flouride?? TV??? Fake space??? **–In our last hour we reveal...
Gotta love it! Vocabulation!! What does it mean? Does it mean squat? Squat, does it mean? Radioactive regolith. Hot rocks. Squat rocks. Melting away at the icy bum of our spinny space pear. Big ole chunks. “The process of melting we observe has probably been going on for thousands or maybe even millions of years...
I LOVE me some newfangled wordification! I’ve always prided myself on my intrinsicallastic abilities to vocabulate quite scrumtralecently on a regular tip, so whenever Josh comes acrossed new additionistical verbage, it is immediately added to the collective unctuosiousness. Thereby a show title was born! If you can tell us the minute mark where the word...
