Gravity tends to clump stuff up.

But not the same way luminous matter (the "standard" stuff) clumps up. The mass distribution needed to explain spiral galaxies assumes that this "dark matter" remains at the periphery of the galaxy, keeping the rotational velocities constant as one moves away from the galactic center. So now, dark matter has to be something that doesn't interact with gravity (or curved space-time) the same way normal matter does. It curves space-time like normal matter does. But it isn't pulled into the gravity well (space time curve) toward the center of a galaxy the way other matter is.

Or, our model of gravity/space-time isn't quite right.

I probably just crossed some age line where "everything I have now is good enough dammit!"

I am still using a 13 Pro Max, so you're not alone.

This whole "buy a new expensive phone every year or two" mentality has always bugged me. Yes, "battery life is better" on a new phone versus a not-new phone... but the question SHOULD be "is the battery life on that not-new phone actually an issue?". And yes, the cameras on a new phone are probably better, but is there an actual practical difference the end user will actually see?

A lot of those arguments seem to be post hoc justifications for a purchase decision that was already made.

It probably is all around us, but does not interact with regular matter a lot.

It appears not to at solar system scales. Because we can plot the trajectory of a satellite to intercept an object beyond the orbit of Pluto without considering its effects. But at galaxy scales, it distorts the effects of gravity and galactic rotation sufficient to be easily observable.

Magic stuff, this dark matter. It knows when to be there and when not to.

Comment what is a reserve? (Score 2) 67

a government or anyone may decide they need a reserve of something in case it later becomes unaccessible when needed. When can a government *need* BTC? Needing oil or food or water or weapons or gold is understandable, those are real things and it is possible to run out of these items and be in a position where access is limited.

If one "needs" crypto currency they may either purchase it in the market freely or just start their own, even Trump has done this on multiple occasions.

Note, it says "a reserve", not a speculative asset to gamble on its price.

Comment Re:Raise the costs even more! (Score 5, Interesting) 54

Assuming equal regulatory burden, fission power is cheapest, not most expensive. For example, for an equivalent safety level, coal plants would need to capture every bit of reaction products (which currently are vented into the air), store them safely, and place somewhere where they'd no longer cause harm if released. Which for combustion products means forever. The plan itself would need decade-long studies wrt its localisation, many rounds of votes among the regional population -- etc. And throw in another 10x cost factor of bureaucratic costs.

The reason? Completely banning nuclear power was unfeasible politically, but adding layers after layers of "safety" was easy to be voted in.

Result? Hardly any new plants have been built. A good part of existing installed power dates back to the first generation -- which was indeed unsafe (as expected of any new technology). All three plants that failed have been built in the '60s.

Has anyone heard of "Plex" before this was posted here?

I haven't.

Plex, Jellyfin, Kodi, etc. are somewhat popular pieces of software among those people who have home media streaming libraries. People like me who like to purchase DVDs / BluRays of movies and TV shows, rip them to disk, and then never touch the original media again.

They all descended from the original XBox Media Player, if you remember that from way back.
