Reply to comment by psychothumbs in Asteroid-Mining Startup Plans First Private Mission to Deep Space by psychothumbs

I'm guessing they are hoping to find gigantic pure nuggets of these 'rare' earth elements so to sidestep and corner markets on earth. But then if something like that happens, then we immediately become a post-scarcity society wrt to those metals. Then what? I think that's the point - they find these 'nugget's of pure metals (as pure as something like that can be ok< I have no idea>) and if they find a large enough chunk, then now they have a lotta things they can pull off - all sorts of 'secondary' things they can now build since the rare earths are now cheaper than water.

You want a solid platinum car? go nuts. etc etc. All those metals are still useful, but we'd have to settle with them being too cheap to sell direclty, but the since they are not worth it in a pure form, doesn't they aren't useful.

Meh, just how I've mused about it.

> I see nothing wrong with a factory which operates only for 2 weeks any month

Do all the energy-intensive processing during the day

Do all the manpower intensive maintenance at night

Just a scheduling problem

Reply to comment by Gutotito in Earth's inner core may be slowing down, but “Nothing cataclysmic is happening,” says Hrvoje Tkalcic, a geophysicist at Australian National University. “The inner core is now more in sync with the rest of the planet than a decade ago when it was spinning a bit faster.” by clayt6

We do underestimate how one minor variable could turn a usual occurrence into a catastrophe. Whether that change is immediate or over a longer period of time, we could only guess.

Unfortunately, we are going to have to face the elephant in the room - eventually. Our lives are in the hands of statistical anomalies and strange nonsensical occurrences, time for us is not endless .

It happens every couple decades. It’s a nothing story, cool to scientists, conspiracy bait to laymen.

I'm no planetcoreologist but I reckon a planet sized spinning blob of molten metal slowing noticeably over a mere decade might be cause for a smidge of concern?

Reply to comment by MoogProg in What time is it on the Moon? - Satellite navigation systems for lunar settlements will require local atomic clocks. Scientists are working out what time they will keep. by speckz

I read an estimate of about 22 milliseconds per year time difference between Earth and Moon due to relativistic effects. Which is about 1 second every 45 years or so. Probably just an easy leap second every half century.
