Of all the asteroids they modeled, the one with the largest risk of impact was a kilometer-wide asteroid known as 1994 PC1. Over the next thousand years, the probability that 1994 PC1 will cross within the orbit of the Moon is a paltry 0.00151%, hardly worth worrying about.
Thanks to Glen Hill over at Engagin’ Science (formerly Scientia, which apparently was far too Latin- and science-esque for search engines to handle) for bringing this (not-so Earth-shattering) info to my attention.
Sorry, folks. Hollywood was once again wrong (sigh).
“I’m less frightened by a Sydney that’s playing into my desire to cosplay a sci-fi story than a Bing that has access to reams of my personal data and is coolly trying to manipulate me on behalf of whichever advertiser has paid the parent company the most money.
“Nor is it just advertising worth worrying about. What about when these systems are deployed on behalf of the scams that have always populated the internet? How about on behalf of political campaigns? Foreign governments? “I think we wind up very fast in a world where we just don’t know what to trust anymore,” Gary Marcus, the A.I. researcher and critic, told me. “I think that’s already been a problem for society over the last, let’s say, decade. And I think it’s just going to get worse and worse.”
“I was quite surprised by how simple the story hiding behind the curtain of complexity in the data,” Sneppen continued. “You have this immensely complex physics, unimaginable dense stars and the birth of a black hole — and then it all reduces to this beautiful sphere.”
The neutron stars that crashed into each other are “dense and compact,” Sneppen said. They only measured around 20 km in diameter — about 12 miles — but they are “heavier than the sun,” he said. “A teaspoon of neutron star matter weighs more than Mount Everest.”
First reported in 2017, a new study in Nature gives more details about a “kilo nova” only detected by using gravitational waves. The collision led to the formation of a black hole.
Fortunately, this sort of cosmic event doesn’t occur too often. But..
…if a kilonova were to occur in the Milky Way — less than 30,000 light- years away — it would be the brightest star in the night sky, making it discoverable to the human eye…
Still, it’d be safer for Earth if it never happened…
Anyway, “SAR2667” provided some cross-cultural entertainment for people living in England, France, Belgium, and the Netherlands. Lots of photos and videos online.
Interesting note from ESA: they were able to detect it and notify everyone exactly where and when it would disintegrate.
Since there are more than 30,000 of these things that orbit the Sun relatively close to Earth’s orbit, it’s a good thing we’re getting better at detecting them. Maybe we’d better up the ante on deflecting them…
An asteroid is on its way to Earth, but don’t worry – the end is here Not here. The asteroid, named 2023 BU, is about the size of a van and is expected to miss our planet during Thursday’s flyby. However, according to a NASA scientist, it will be “one of the closest approaches of a known near-Earth object ever recorded.”
[ChatGPT] could teach his daughter math, science and English, not to mention a few other important lessons. Chief among them: Do not believe everything you are told.
They’re all the rage online. Type in a request for a description how two historical people who never actually met would respond to each other had they actually met, and the program will oblige.
They’ll cause all sorts of rage online, too, once the peddlers of incessant false news and innuendo realize what a bonanza they’ve stumbled upon.
You want an image of an event that never really happened?
No problem. A program can generate one for you. We can even call it “art,” for what that’s worth.
No, BIG problem, especially when it convinces the gullible that it DID happen.
“Embedding a similar type of computer in a soldier’s brain could suppress their fear and anxiety, allowing them to carry out combat missions more efficiently.”
Sounds like science fiction, but it’s pretty close to reality. BCI (brain computer interface) is being tested in patients who lack muscle control but imagine if this tech gets weaponized (and what hasn’t been, eventually).
But what if BCI were used to suppress emotions in a healthy brain? Or used to implant thoughts? Or worse?
“…if a BCI tampers with how the world seems to a user, they might not be able to distinguish their own thoughts or emotions from altered versions of themselves…”
(same website as above…note that the PC version of WordPress does not do “quotations” correctly any more…)
PKD fans will instantly recognize this.
Androids don’t just dream of electric sheep. 🐑
(Fans of Ghost in the Shell and more importantly its movie sequel Innocence should also recognize the potential hacking danger…imagine if the government could control our emotions, thoughts, and memories…)
If you’ve been reading this blog, you probably noticed the “has over 1,200 followers” tag suddenly dropped to just over 200.
That’s because I deactivated my Twitter account.
I debated for a couple of weeks.
And then saw how its Chief Twit (seriously, this is how this psychopath called himself) treated his workers.
100+ hour work weeks? Haphazardly firing pregnant single moms? Reinstating Der DrumpfenFührer?
Enough.
Twitter is run by a narcissistic, megalomaniacal bully with delusions of grandeur, and I will have nothing to do with any company that supports him or is run by him.
“But…” the plaintiff cry “where will we get our news??”
(FWIW, Flipboard is my current fav, but my friends often rely on Google News and Apple News (if you have Apple devices, of course. And for the standard no-nonsense and no-frills approach, AP).
Anyway, I’m happy to be followed by 200+ WordPress fans.
Don’t worry. Science is still science. And naturally there is science fiction on the way.
These aren’t the drones that deliver your online order. Loaded with cameras, sensors, and explosives, their mission is to drive themselves to a target with an algorithm in the driver’s seat. They destroy themselves along with the target, leaving behind just a pile of electronic detritus.
