- Comment on is white light "white" because that's what our start emits? 1 day ago:
I’d assume if we lived on a world where UV or infrared wavelengths were the most intense we’d evolve eyes to work around the problems that our eyes have. There probably is an upper and lower limit to the wavelengths that animals on earth have adapted to and there probably also is some physical limit (imagine wavelengths of 1 kilometer). However the ability to see in the wavelength that is most intense is a big advantage since everything that does photosynthesis is probably that colour and being able to see those tasty morsels would be an advantage.

It depends on if our cone cells which are responsible for colour reception would have evolved differently. With our current sun and atmosphere they have evolved to perceive a range of wavelengths that are the most abundant/intense and don’t have a drop in intensity in the middle. Here is a graph showing solar and terrestrial wavelength intensities compared to wavelengths we have evolved to see.
So to find out if the range of wavelengths we are able to see would be different if our star were a red dwarf we would need to take the emission spectrum of the star you’d want to replace our star with(the orange part), then remove from that the percentages of each wavelength that our atmosphere absorbs to get the terrestrial wavelength intensities (the dark blue part). Then you could probaly look at that graph and take a chunk out of the Y-axis that covers the highest intensity wavelengths (cause plants would probably have that colour and we’d want to see those) while not getting too long and also trying to avoid lower intensity dips in wavelength. Then you’ve got your visible colour range. If that range is the same as our current one then white stays white. In general objects that appear to us as white reflect or emit a mix of waves with different wavelengths in such a way that we perceive the total of it as roughly equally blue, red and green. If the visible colour range we perceive is different, then our cone cells would also be triggered at different wavelengths.

Following the headlines logic: Germany is angry at this post right now for overgeneraling them in a topic where there are a lot of fake news and and propaganda spreading actors already. Germany will now go and make itself tea.

- Comment on the 'it' in 'it snows' doesn't refer to anything 1 week ago:
That somehow feels right. I still kind of want some phrase that you could substitute for it though. The most correct feeling thing I could think of are seasons as in ‘the summer rains’. But from a logical standpoint a concept that is defined by humans producing something material doesn’t really make sense since a concept isn’t material.

Which sentence do you mean?
- Comment on the 'it' in 'it snows' doesn't refer to anything 1 week ago:
‘It’s raining’ must refer to the same it as the one in ‘it rains’. From that we can gather that the entity referred by ‘it’ must be quite capable as it can do the raining as well as be raining. However ‘It’s cold outside’ could refer to the air as in the air is cold outside. Similarly the ‘it’ in ‘it is the case’ needs some context in a prior sentence or something else in the real world otherwise the sentence doesn’t make sense.

I think it’s OK. It looks very normal in this video. Not perfect is fine for a Pope who wanted the grave of a normal person.

- Comment on The best thing *you* can do for the fediverse is *just be kind* 2 months ago:
I said don’t engage with spam bots. And no I can’t fully ignore baseless negative comments when I see them. They still register in my brain. I would need to have a filter in my brain or eyes that blanks them out. I wish I had one. Because they affect me even if they aren’t directed at me. Not in the same way but more in the sense that when you see a mother hitting her child on the train you feel compelled to say something. If I don’t I feel a sting and it doesn’t sit well with me. Because I care about others in general. Not implying you don’t. I know not everyone is a helpless child but a lot of people are mentally not in a state where they have the ability to deal with this stuff myself included sometimes. That’s also why I try to be kind to strangers on the internet in general.

We do not need all the engagement. Just engagement that most lemming users enjoy. The comments of spam bots for example are also good for engagement but are not enjoyable content. I personally hate being pissed of online cause it caries into my real life and people in general also do so most people come to this general idea that they don’t piss anyone of and expect other people to come to the same conclusion of not pissing anyone of. This leads to a less toxic environment which allows them to spend more of their time and energy on more productive stuff. Cause at the end of the day needlessly making other people feel bad for your own entertainment is a downwards spiral if everyone’s doing it.

Oh that’s a good explanation for four twists. It sounds pretty likely that this was factored into the design.
- Comment on Actually it's pretty cool 3 months ago:
Interesting. Their proposed stelaris reactor only has four twists in it though if I interpret the Plasma’s shape as shown in their paper correctly.
It could be due to the generators much larger size but that’s just a hobbyist’s guesswork. Here a comparison of the height of one coil to other reactors and a human:
I’m not sure yet how much they are exaggerating with their capabilities and the reactors feasibility since I’m not a physicists and my only trust towards them stems from them working with the Max plank institute. But I hope it’s solid work. I’m looking forward to the reactions from other physicists to the plan though.
