As far as we’re aware, dark matter only interacts with the universe gravitationally. It doesn’t even interact with itself, which is why we don’t see dark planets/stars/galaxies popping into existence. It only follows normal matter around.

As for why it’s not called cold, is for two reasons:

1. Cold gases of normal matter can condense to form stars. Dark matter doesn’t interact with itself, which implies it cannot condense into more concentrated forms of itself the way a gas cloud can eventually form a star.
2. We just don’t know what the stuff is, it could be clouds, planets, black holes, neutron stars, brown dwarfs, etc. But our best observations of dark matter are from very large distances away where we can measure the distortion of spacetime due to dark matter. We can’t see these smaller objects at these distances. But we should be able to see other clues that would indicate it’s normal matter.

If it happened to be clouds of gas and dust that overall had a net gravitational effect on the background galaxies, we’d be able to detect the spectral lines of these clouds. Same for just about all the other objects in that list. In some cases we do detect intergalactic gas clouds. But in places where there’s very clearly unaccounted for gravitational lensing, there isn’t any sign of this. So far the only things we can match up to the observations is a mathematical model of the stuff.

Reminds me of an interaction I had a long time ago.

Crossing my fingers and will be contributing to this hat trick come November

This both warms and breaks my heart 💚

Please do not boop this snoot for your own safety. Sometimes they get curious and may investigate you if you’re near their waters. Please do not freak out as they’re just curious but above all else: Do not boop

Green flavored is the best

Good luck China. Without reusable rockets, this will be extremely expensive. It’s certainly an issue that can be brute forced with spamming more rockets, but each launch won’t be as cheap as it could be if you could reuse each rocket.

I’ve been seeing a few details coming out from this about gas pipelines being a big reason for a push into this particular region of Russia. But things I haven’t seen talked about are things like this will cause Russia to have to spread troops thinner from the eastern fronts to handle this incursion. It’s also far enough away from Belarus that they don’t need to worry about any collateral damage. And most importantly, it’s in the general direction of Moscow so it cranks things up a notch in terms of proximity to the general population.

Oh wow, so the memes got the look down correctly! 🤣

I’m still doubtful they will return on Starliner. After all the issues they’ve discovered since delaying the vehicle’s return, it seems like returning on Crew Dragon would simply be the safest option at this point. Political optics be damned, the crew isn’t expendable.
