Under the CMB method, it sounds like the calculation gives the same expansion rate everywhere. Under the Cepheid method, they get a different expansion rate, but it’s the same in every direction. Apparently, this isn’t the first time it’s been seen. What’s new here is that they did the calculation for 1000 Cepheid variable stars. So, they’ve confirmed an already known discrepancy isn’t down to something weird on the few they’ve looked at in the past.

So, the conflict here is likely down to our understanding of ether the CMB or Cepheid variables.

Except it’s not that they are finding the expansion rate is different in some directions. Instead they have two completely different ways of calculating the rate of expansion. One uses the cosmic microwave background radiation left over from the Big Bang. The other uses Cepheid stars.

The problem is that the Cepheid calculation is much higher than the CMB one. Both show the universe is expanding, but both give radically different number for that rate of expansion.

So, it’s not that the expansion’s not spherical. It’s that we fundamentally don’t understand something to be able to nail down what that expansion rate is.

And the article content posted is just an excerpt. The rest of the article focuses on how AI can improve the efficiency of workers, not replace them.

Ideally, you’ve got a learned individual using AI to process data more efficiently, but one that is smart enough to ignore or toss out the crap and knows to carefully review that output with a critical eye. I suspect the reality is that most of those individuals using AI will just pass it along uncritically.

I’m less worried about employees scared of AI and more worried about employees and employers embracing AI without any skepticism.

Kids these days with their containers and their pipelines and their devops. Back in my day…

Don’t get me started about the internal devs at work. You’ve already got me triggered.

And, I can just imagine the posts they’re making about how the internal IT slows them down and causes issues with the development cycle.

Yeah, my hope is the small learning curve to join the fediverse means we don’t end up with the bulk of the active posters on reddit.

My fear is that Lemmy is about to see some attacks the fediverse isn’t ready to defend against.

Yeah, Usenet is what my brain mapped Lemmy to. You get your feed and post through your server. You read posts from others on other servers. Each local server decides what feeds it will carry.

Of course, there’s no central hierarchy for the communities like Usenet had.
