    No, it’s observation. An experiment involves manipulating an independent variable while controlling other variables. There’s none of that in space, not counting the ISS and Apollo. That said, you can still test hypotheses using observation. And that’s equally true in both astronomy and in social sciences.









  • These pods are only used on rails with very low ridership. They would switch to a train if ridership increased.

    Look at it this way: you can have a train that has a capacity of 100 people, but it only runs once a day due to the low demand, and only 2 people want to ride it at that time of day…Or you can have 10 pods, which do not require as much railway maintenance, and they can carry the 10 people who actually want to use this railway, completely on demand.

    Yeah, a train is better if you want to move ten thousand people a day at peak hour. But this is a cheaper way to move ten people at different times across a day. And it’s a cheaper way of inducing the demand that would justify the more efficient kind of expansion.


  • Proud luddite here. The original luddites destroyed machinery owned by capitalists which threatened their jobs. The choice was either destroy the machines, or stand by and become unable to feed your family while a rich man gets richer.

    I have no opposition to technology which is used for good, and whose control is placed in the hands of the workers. Your self-hosted AIs are fine, although I do ask that you only use energy intensive processes if you have solar panels. After all, this planet is the only one we’ve got. At our current rate of pollution, soon the world will only be inhabitable to AI.

    But I downvote anything promoting corporate AI designed to replace people’s jobs. I am all for replacing human jobs, if the humans get to relax and live comfortable lives afterward. But I am against replacing jobs if we choose to have a society where you need a job to live. That’s not nature, it’s a choice we make as a society. The minute you automate someone’s job, you do necessarily admit that society doesn’t need that person’s work to get by. The only reason they shouldn’t get to put their feet up and take it easy is political. And politically, we have decided instead what happens is they die. That’s unacceptable, and until it changes, we can’t afford to have job replacing machines.





  • Actually, cats really are alive and dead at the same time according to the many worlds interpretation. Under classical quantum mechanics, we say that superpositions collapse when observed, and since the cat is an observer of the quantum event (since the cat would die if the atom decayed), then the cat’s presence resolves the superposition. Thus, the cat is never in superposition.

    However, according to the many worlds interpretation, observation does not collapse superposition. Rather, it simply expands the superposition to include the observer. So the cat, as an observer of the quantum event, really is both alive and dead. And at the moment that you open the box to see whether the cat died, you will also observe the quantum event and become part of the superposition as well. You will both see a dead cat, and see a living cat. But your consciousness only experiences one of these possibilities. Presumably, you have another consciousness in the other possibility observing the cat in the other state. Two separate timelines have been created, which will each progress on their own according to causality. We may also call these timelines worlds or universes, seeing as they’re mostly self contained.





  • Narcisstic Personality Disorder is a lifelong disability with no cure. You can be a nice person with NPD. You can be a wise person with NPD. You can even be a healthy person with NPD, because disorders and illnesses are two different things. Having NPD is like having type 1 diabetes. You can live a normal life, but it’s still going to take constant attention to treat, and some stuff is always going to be just a bit harder for you. The myth that people with NPD are abusers is pseudoscientific bigotry. There are plenty of self aware people with NPD and there are plenty of non-abusers with NPD. People with NPD are most likely to be the victims of abuse compared to the abuser, but the kind of people who prey on the disabled to satisfy their own desire for cruelty don’t want you to believe that.
