- Comment on New Objective: Convince an astronaut to use the Fediverse from space 10 hours ago:
This might be more achievable than it sounds: there is quite a bit of space content on Mastodon already. Seti have an official account along with several astronomers, observatories and astrophysicists. Nasa possibly used to have an official account that has gone inactive. I can’t see any astronauts there at the moment but that could easily change

Off topic but anyone looking for serious criticism of Newton only has to read about his time at the Royal Mint sending counterfeiters to face the death penalty: www.londonmintoffice.org/…/184-mud-and-madness-2

I enjoyed this video, it’s funny because the Cornish accent is the same in Cornish as it is in English
- Comment on CEO of Palantir Says AI Means You’ll Have to Work With Your Hands Like a Peasant 2 days ago:
It would be interesting to know where your friend works and what kind of application it’s on, because your comment is the first time I’ve ever heard of this level of automation. Not saying it can’t be done, just skeptical of how well it would work in practice.
- Comment on The lithium boom: could a disused quarry bring riches to Cornwall? 2 days ago:
If it creates some jobs then that’s good regardless, but of course you’re still right and I saw in the article the quote from the local MP was along the same lines:
“Mining is more capital intensive than it used to be, and not as labour intensive. Part of the challenge is sharing the prosperity”
Personally I really hope this takes off as it could be great for Cornwall. The big challenge will be whether it can compete with international markets if it gets to that point.

The Hopkins tweet is somehow way worse than I expected, and I already knew how awful she is. No joke, no argument, just literally listing minorities and reacting with disgust. I don’t know how anyone can stand her.

ec.social-network.europa.eu/@EUCommission
It has over 3k posts and 145k followers. Mastodon posts don’t federate to lemmy unless they tag a lemmy community
- Comment on Search Engine Podcast Episode: The Fediverse Experiment 3 weeks ago:
Integration between lemmy and mastodon is clunky, I think it’s possible to subscribe and post to lemmy communities from mastodon but there’s no way to follow a mastodon account from lemmy.
- Comment on What are your technology mispredictions? 3 weeks ago:
I remember I wasn’t impressed with smartphones when they first appeared. Phones were already everywhere and gimmicky variations were appearing all the time. The Internet and social media were much less popular and to use them you generally wanted to be sat down at a desk. At the time it really felt like anyone with a fancy phone was just going to use them for calls and text and nothing else.
- Comment on Two Palestine Action Hunger Strikers at Risk of Imminent Death 4 weeks ago:
I realised I didn’t know what their demands are, but it’s in the article:
The group’s demands include immediate bail, the right to a fair trial, the deproscription of Palestine Action, the shutdown of Israeli weapons firm Elbit Systems’ sites on British soil, and an end to alleged prison interference with their letters and other communications.
Worth noting that they’re not asking for any charges to be dropped, so they would probably still face long prison sentences for criminal damage even if the government agreed to all of this
- Comment on 4 weeks ago:
Personally I think it’s very cool that different kinds of software can interact like this, it makes content more visible for everyone. I’ve also heard some people say they don’t like the formatting, and tags can be confusing because they don’t mean anything on lemmy.
My advice is keep doing it, just make sure to follow community rules.
- Comment on Great British Railways flies the flag as logo goes back to the future 1 month ago:
Ah sorry I was talking about the train livery. You’re right, I don’t think the logo will be unpopular
- Comment on Great British Railways flies the flag as logo goes back to the future 1 month ago:
The geometric design thing can sometimes look quite generic, like not quite original enough to really stand out and also not quite the classic look of a solid colour. But then I think this one looks decent enough.
Of course I’m not a designer or anything and I’m thinking purely about how it will look on a Hornby train set.

- Comment on Could rising sea levels caused by climate change be thwarted by digging a big hole at the bottom of the sea? 3 months ago:
I have a grain of crack here for those who are interested.
You don’t need to do many calculations to see that the AI has gone slightly wrong. Since water covers roughly twice as much of the Earth’s surface as land does, lowering the oceans 1 inch should raise the land by about 2 inches, assuming that the volume of dirt isn’t changed by the process of moving it.
More precisely: Area of the oceans = 361,000,000 km^2^ 1 inch = 2.54cm = 0.0000254 km Volume of dirt = 361000000 * 0.0000254 = 9169.4 km^3^ Area of land on Earth = 149,000,000 km^2^ Height of dirt spread over land = 9169.4 / 149000000 = 0.0000615 km = 6.15 cm = 2.4 inches
Not going to say how many Everests as estimates for the volume of Everest seem to be all over the place. But the point stands that it’s a huge amount of material making the idea somewhat impractical.
- Comment on Should Neutron Stars be Added to the Periodic Table? 4 months ago:
we have assumed that Rex is comprised of a uniform nucleon fluid, with protons, neutrons and electrons in an idealised 1:8:1 ratio
This is how the author is estimating it, they are assuming 1/9th of the mass is protons. No idea how good that assumption is though, there is a source which doesn’t look the most convincing
- Comment on Should Neutron Stars be Added to the Periodic Table? 4 months ago:
After reading I realised that this proposal isn’t a single new element for all neutron stars, but a separate new entry on the table for every individual neutron star in existence, unless there are two that happen to have the exact same number of protons which is unlikely. Sounds good to me

Strange how much higher the top one, 123456, is than the others, and how the most popular ones with repeating numbers also have 6 digits. Why do people like 6 digits so much more than 5 or 7?

Unfortunately yes. I’ve met people who ask chatgpt about absolutely everything such as what to have for dinner. It’s a bit sad honestly
- Comment on Where do British elites get their news? Publishers, social media and AI 6 months ago:
41% of all adults and 60% of decision makers according to the article. But that includes online newspapers, and the number who actually named their favourite newspaper was far lower.

Anyone else shocked that 19% of people in “senior jobs and leadership positions” read the Daily Star??!!
- Comment on Time travel doesn't work unless you also have teleportation. If you travel to the past/future, Earth will be in a different position in its orbit, and you'll die in space. 6 months ago:
This is interesting because the most “realistic” (i.e. still not realistic) depictions of time travel in fiction involve travelling through a singularity or wormhole. So you probably have to be in space to start with, but also both ends of the wormhole have mass so they can be orbiting a planet or star and stay within a stable distance of it. It solves this particular problem (just leaving the other usual problem of causality!) It also proves your point since it does allow travelling in space, in fact it allows travelling faster than light.
I think the converse is true as well, that if faster than light travel is possible then time travel must be possible, at least if you take relativity at face value. As others have pointed out there’s no universal reference frame, and for any journey that is faster than light in one reference frame, there is another frame in which the journey goes backwards in time.
