That do. The failure comes if the spacecraft use lower air pressure, then the ink is pushed out of the pen by the pressurised gas in the ink
The same thing causes some pens to leak in aeroplanes.

Sure, but if we take it as true that light speed is the same in every direction – which is perfectly consistent with everything ever measured – you can measure speed between two endpoints using two atomic clocks and a synchronised experiment, with corrections for the relativistic effect of moving the clocks to the different places

Unfortunately you then get the low bandwidth of the frequencies that can penetrate that much ground

That speed of causality is usually at least 3 times better than you can get in real life
You get 300 million metres per second in light (including radio in free space) so wifi to your laptop is at that speed
A wave in wire (eg ethernet over cat6 cable) is seldom better than 0.9c
Laser light in an optic fibre (how almost all data moves long distance) is about 100 million metres per second as it follows a zig zag path in the fibre reflecting off the walls of the fibre
The future promise of starlink – where your connection goes to a satellite then to another and another satellite until being down linked to the server farm hosting the content – should provide much lower latency

Nothing is ever a generation’s fault. There are and were good and bad among every generation. Some had luck buying into housing or business at just the right moment that value went up
Boomers, X, and older Millennials all had more luck than younger Millennials; at least the Millennials and later had recognition of autism and ADHD.
My autistic friends weren’t diagnosed until their 40s, some had to work it out out on their own after the internet became popular

It was a longboat, not a raft, and he had a sextant and almanac so he could look up rise and set times for stars. He lacked charts.
It was a remarkable feat

I have a friend who’s sure I’m on the spectrum, and points at things I talk about as my current hyperfixation. Meanwhile I’m talking imprecisely forgetting detail.
If I’m on the spectrum, I suck at fixating on stuff

Kangaroos form two sorts of groups
- Like most herbivores, they have one male and many females in a mob (kangaroo equivalent to a herd)
- Males outside that mob form loose groups for defence and within that they fight to establish dominance and the top roo may challenge the male lead of a mob to take it over

I used to do that in the swimming pool (I have always lived far inland) it’s often called dangerous on the mistaken belief that it’s like shallow water drowning where someone hyperventilates to swim underwater longer; since those people have blown off so much CO2 they don’t get a signal to breathe and suffocate.
Our method doesn’t involve hyperventilation, and wow does the need to breathe get strong

Evolution isn’t aimed. A T-Rex needs to be good enough to hunt enough food.
Our ancient ancestors smashed the skulls of animals killed by African predators to eat the brains, smashed bones to eat the marrow.
Later as our ancestors became bigger and stronger they hunted and needed to communicate with each other to effectively track and take down an animal. Maybe they needed twenty words. Chickens have three words (or cluck patterns)
At the same time women collected stuff and needed to share how to identify this from that with younger women. They might have needed a hundred words.
Then those who could talk better were more attractive to the other sex than those who couldn’t (even now being well spoken is attractive) then a few millions of years later we’re making stone knives, hammers, axes; then ten minutes later aeroplanes and machine guns
In short: we had it hard enough we needed to share information. We later found communication sexy. T-Rex had no such trouble. We seem to be the only animal that solved “scavenging is dangerous” and “hunting is hard” with talking to each other rather than by getting bigger and getting claws or vicious teeth
I understand we selected for tall by fighting humans

Yeah it’s outside my expertise so I’m bad at the detail.
Normal process is the nice efficient anaerobic process that produces ATP from glucose
Cancers use an all aerobic process which is less efficient but faster at producing ATP

There was that man who was all in on Google.
He had a telemedicine appointment for his son who had a problem with his penis. Dr asked him to send a close-up photo so he could diagnose the skin condition
So the guy takes the photo with his pixel phone and sends it
The phone automatically backs up the photo
Google’s AI says it’s child porn, his account is deleted and police are contacted
Police look into it and say “not porn, totally fine” but have to go to his house to tell him the was no problem because his phone was Google, his internet was Google fibre, his email was Gmail and his photo album was on Google and all that was irrevocably deleted

You can still enjoy the movie and the book. You can ignore the upcoming film. New media cannot ruin old media, follow the example of the matrix fans who say “shame they never made a sequel”

When this happens, the mitochondria start burning sugars using oxygen as a fuel source
That’s also (almost?) universal in human cancers
