Reply to comment by InGenAche 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
"Noticably" doesn't mean a lot, on a human scale, when it's 21st-century scientific equipment doing the noticing.

You should probably read the article before posting comments like that.

It's the pollution in our beans that did it.

Plus copy editing standards have gone through the floor for both fact checking and simple spelling and grammar errors.

I would actually have to disagree since Rocket lab is sending two photon spacecraft to Mars next year

Who's gonna be the first one to be spaghettified by a black hole? That's one unenviable first.

one of the reasons gen-x is so jaded and dubious.
we set in classrooms and school libraries across the country
only to see tragedy
we were thrilled all morning
that ended after ~70 seconds
yet most of still dream of stepping into the dark void above

There's even supposition it may reverse direction, and researchers are looking for evidence of past impacts.
Thing is, humans didn't even know the core-as-a-core existed 60 years ago. They were still thinking that all the surface stuff was one big shell. So while it's fascinating to learn new things, figuring out what this means will take time.
And NOBODY knows for sure what's next. It's outside of our control, let's enjoy the mystery.

I applaud the ambition…However, anyone can “plan” a mission and secure some VC funding. At the end of the day, the only commercial space company launching anything past GEO anytime soon is SpaceX so…Yeah I think asteroid mining is a little ways away.

The one potential saving grace I see for SLS is that there is a realistic escape aystem

So you’re saying this is all because of some US government secret experiment that has chemically castrated us all and polluted our oceans?

Possible. But umless needed, it might get cracked into O2 and propellant. You can always recombine, the energy is probably gonna be really cheap. I've always thought smelting on the earth crossing returning orbit would be profitable, but certainly not now at bootstrap time.

It does, but the same is true for satellites, and the answer for both is to build a clock that if run on earth would be wrong, but in it's designed environment is perfectly synced with clocks on earth.

The problem is that if you wake up at the same time every morning, every day you're 37 minutes more out of sync with sunrise and sunset, which would be unacceptable when spacewalks are common.

A majority of the first asteroid mining(s) should be used to gather and sell water for fuel, space infrastructure, and manufacturing.
The other materials coming as a bonus, possibly used to contain the water in transport.

Reply to comment by patasthrowaway in Asteroid 2023 BU about to pass Earth in one of closest ever encounters by C1519
Yeah, I'm just browsing the sub now since I remembered the local time it was passing and I figured why not go out and see if there's anything there haha.
Kinda hard when I couldn't find anything about what direction to look towards here and since it was the closest to latin america I probably had no chance anyways being located all the way up in Norway.
Always fun browsing r/space though!

Is the mechanism that causes this comparable to how a pendulum with a spring instead of a string goes from bouncing up and down to swinging side to side?

A smidge of concern to who?
