Interstellar! If only…

September 26, 2024

According to Thorne, who served as a consultant on the science of Interstellar, quantum mechanics could hypothetically explain a way to time travel via wormhole. So far, it’s a thought experiment that leads to the conclusion that you’d lose information along the way—not very practical.

First off, I’m incredibly annoyed at the way WordPress has screwed up the “quotation” function. It seems they are more focused on encouraging bloggers to use AI to write.

Uh. I don’t need AI. I blog. The end. WTH is the point of using AI to write my thoughts? It’s already being trained to USE my blog in the first place! Idiots.

OK. Second, the Popular Mechanics article I’m linking to is entitled “Interstellar travel is possible if we break into a higher dimension, scientists say.”

Only, that is NOT what scientists say. It’s still a thought experiment!

Starliner to Earth: “We have a problem…”

Starliner, the Boeing spacecraft whose launch was delayed by a helium leak, has now developed four additional helium leaks after docking successfully with the ISS.

They had to delay the docking due to a little problem with thrusters…

Five of the 28 thrusters were not operating but, after troubleshooting, Boeing recovered four of Starliner’s malfunctioning jets and NASA allowed the spacecraft to dock.

So their return to Earth has been delayed so that they can run some more tests.

I sure hope they have built some redundancies to this system. Remember, this is Boeing. QC is not exactly high on their priorities list…

Boeing Starliner delayed. They should delay again.

A contractor for Nasa urged the space agency to conduct more safety checks before the highly-anticipated first launch of its Starliner rocket – which is set to take off as soon as next week – “before something catastrophic happens”.

It was supposed to launch last week, but someone spotted a valve problem — *minutes* before the countdown procedure was about to start.

They’d better check for door plugs while they’re at it.

Boeing does not give a rat’s ass about whoever uses their products. They‘re only interest in paying dividends to stockholders. And of course paying the CEO’s ridiculously high salary.

NASA is trusting the future of space travel to people like Musk and companies like Boeing. Using taxpayer money to reward greed and incompetence.

We can do better than this.

Nuclear power on the Moon. Gee, no problem…

The South Pole, where power plants are likely to be constructed (without human help…)

“The truth is that nuclear is the only option to power a moonbase,” says Simon Middleburgh from the Nuclear Futures Institute at Bangor University in Wales.

https://www.bbc.com/future/article/20240417-the-nuclear-reactors-that-could-power-moon-bases

So far there are two major consortiums that have plans for moon bases:

The Artemis Accords, with 36 countries (the US, Japan, South Korea, UAE, India, etc.)

The countries that don’t like the US, the UK, and Canada (China, Russia, Belarus, Venezuela, Pakistan, South Africa, Egypt, Ajerbaijan)

OK, maybe a bit of an exaggeration, granted.

But there is no doubting the political ramifications of two competing groups of astronauts (cosmonauts, taikonauts) on the Moon.

And just wait until they get to Mars.

Imagine what might happen. (I did!)

When Google Gets it Wrong

May 10, 2024

Technology is becoming marvellously intuitive. After booking a holiday with friends, we were surprised to discover Google had already added the dates…
When Google Gets it Wrong

Google Maps initially listed our house with the correct address but also my family name —- because it thought it was a company.

It took them half a year after I complained about privacy violations to take the name off…

And they also took off the address!

And there is an abandoned house repurposed as an arts and crafts society event place that has the same address as us!

Annoying.

Not the arts and crafts society folk. They’re pretty cool. 🖼️ 📷 🎨

Well, hello, Voyager 1! The venerable spacecraft is once again making sense

NASA says it is once again able to get meaningful information back from the Voyager 1 probe, after months of troubleshooting a glitch that had this venerable spacecraft sending home messages that made no sense.
https://www.npr.org/2024/04/23/1246392066/nasa-voyager-1-spacecraft-talks-back

Hmm. Just a short while ago, Voyager’s days were numbered.

I guess these things were built to last… (also built when NASA got a lot more funding…)

Aristotle had something to say about this…

Today’s literary quote

February 19, 2024
MThomas

It is wise to have decisions of great moment monitored by generalists. Experts and specialists lead you quickly into chaos. They are a source of useless nit-picking, the ferocious quibble over a comma….The expert looks backward; he looks into the narrow standards of his own speciality. The generalist looks outward; he looks for living principle, knowing full well that such principles change, that they develop.
Frank Herbert (Children of Dune)

Another failure from the private sector

“We continue receiving valuable data,” the company said in a statement, “and providing spaceflight operations for components and software relating to our next lunar lander mission, Griffin.”
https://www.nbcnews.com/science/space/private-mission-moon-wont-land-lunar-surface-malfunction-rcna133082

Well, yeah, great. But the Peregrine lander still is a failure. Propulsion leak. Solar panels that didn’t open in time.

And NASA is counting on these privately operated products to get people back to the Moon? And they’ve delayed the Artemis again by another year?

When I was in school, we were all talking about people on Mars, living in permanent communities in the 2020s. And we can’t even get a tiny Moon lander to work right.

Sigh. And after BBC posted “Vulcan rocket” I so had my hopes up. (“The Vulcan rocket,” not “Vulcan rocket,” Spock 🖖)

When AI becomes actual AI…

October 26, 2023

We compared current scientific theories of what makes humans conscious to compile a list of “indicator properties” that could then be applied to AI systems.

We don’t think systems that possess the indicator properties are definitely conscious, but the more indicators, the more seriously we should take claims of AI consciousness.
https://theconversation.com/why-chatgpt-isnt-conscious-but-future-ai-systems-might-be-212860

Last year, an engineer for Google who was working on what was then called “LaMDA” (later released as “Bard”) claimed that the software had achieved consciousness. He claimed it was like a small child and he could “talk” with it.

He was fired.

Bard, ChatGPT, Baidu, and so forth are advanced chatbots built on what’s called “Large Language Models” (LLM) and can generate text in an instant.

But the programs are not AI, strictly speaking. They have no sentience.
