Small-Scale Question Sunday for February 12, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

What’s going on with all the objects getting shot down over the US this weekend?

Not just the US: China and Uruguay report very similar UFO's.

I don't have a contribution as to what they are, but I want to chime in with an objection I haven't seen answered from the aliens crowd- if they're from space, why are they showing up over the arctic and staying in relatively northern locales? AIUI the way de-orbiting works you generally want to do it over the equator, and ways around that are the kind of horrendous energy inefficiency that such small craft would require reactionless drives to overcome(which in turn is a far more fundamental violation of physical laws than "mere" interstellar travel would be). I don't see a way to square that circle into "told you so" memes featuring that guy from the history channel with a perpetual bad hair day unless you go full schizo.

If the objects showing up are aliens, they are certainly not using conventional fusion drives. We would notice the gigantic plumes of plasma from the other side of the solar system. Most reports seem to agree on anomalous propulsion, extremely sudden and violent acceleration. That could just be an optical illusion or error of course.

Alien technology is probably overwhelmingly beyond us, such that we don't understand the principles involved. Maybe once we have stellar-scale particle accelerators and planetary scale computers, a theory of everything, understand dark matter/energy and the origin of the universe, then we can be confident of these things.

Obviously a star decelerating into our solar system would’ve been immediately noticeable since at least the late 19th century, but solar sails or their magnetic equivalent could also be used to decelerate, and this is probably much less noticeable.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
