Be advised: this thread is not for serious in-depth discussion of weighty topics (we have a link for that), this thread is not for anything Culture War related. This thread is for Fun. You got jokes? Share 'em. You got silly questions? Ask 'em.

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.

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!

Notes -
Haven't seen them myself IRL, but I saw them in the documentary Wild Wild Space. I can imagine I'll get a feeling of "the future is now" when I see them myself. Sounds a bit inspiring. A feeling of possibilities. Until there's way too many and the beautiful empty sky is more of a congested mess, heh. But why are they visible? I don't think I've heard of visible satellites before Starlink.
I don't do as much stargazing as I'd like to, but even before Starlink I caught satellite streaks on long-duration telescope photos, and saw dots that looked too fast+smooth to be planes only to discover they were satellites, both fairly frequently.
Starlink is what gets all the attention for two reasons:
They're very close to us, and brightness decreases with distance squared. They start out really bright (peak apparent magnitude 2.6 - the planets and the brightest hundredish stars are brighter but that's about it) and bunched up in "trains" of a couple dozen at a time, and they don't get separated or get dimmer (mag 5 for the first batch, dimmed to 6.3 for the first "visorsat" designs, brightened to 5.6 for the "v2 mini" design) until they've all spread out (under slow ion drives) and raised their orbits to their final altitude. (larger magnitude numbers are dimmer, and mag 6 is about the limit of what can be seen with the naked eye in a dark sky)
They're very numerous. About a hundred countries have put satellites in orbit, two of them have put at least a thousand in orbit ... and yet if you add up all the non-SpaceX satellites put together, SpaceX has more now. Like 50% more if you only count active satellites. It's something like 6000 right now. They literally launched 42 more with two rockets this morning. They're a bit preoccupied with a manned mission at the moment, so they probably won't be launching a couple dozen more until (checks calendar) Wednesday.

They're in a very low orbit, and get much less visible once there's not a giant row of them.
I sometimes lay down staring at the sky, and even with the light pollution being much worse now it's amazing the things you start seeing. Dim stars, thousands of meteors, satellites.

There are hundred of visible satellites apparently, though before seeing Starlink I had only ever seen one at a time.
