Funny, I get more alarmed by light aircraft. It's like... I can see from the outside that it's just a bunch of sheet metal stuck together with rivets. It's not even particularly neat, either — there are gaps and uneven overlaps and stuff. And we're going to get into that thing and fly it up into the sky? Ummm... okay, I guess! 😬

If you understand how a U-shaped piece of paper with two points connected by a tunnel would work...

I'm not sure there's much more to the understanding.

That's how it's possible.

The physics inside a wormhole wouldn't be like that of the paper certainly.

After all, it's not paper and a tunnel. It's connecting two singularities in a way that gets rid of their infinite natures in a physically accurate way.

But it means you can't pass information through them. Because the information can never move faster than light and the space between these two black holes would.

At least that's what I take from EPR=EP

I saw on one of the space blogs (that I'm too lazy to find) that they brought massive bags of super-strong concrete (refractory cement?) for the pad after the last damage, and those bags disappeared so it was assumed the new cement had been used, but they were later spotted elsewhere at the facility, so there was some conjecture that they may have used standard cement again and doing this knowing it is a sacrificial pad. So don't be too surprised, or too concerned if the pad is damaged - the fancy cement is on site.

From the FAA, they got a mitigated Findings Of No Significant Impact, meaning they were given a checklist of like 70 items they had to complete in order to proceed. That was in the middle of last year, and they've been working on that behind the scenes. Most of it was pretty basic stuff.

This experiment marks the first time that UCLA scientists will send rodents to the International Space Station. According to the article, "After living in microgravity and receiving NELL-1 injections for about four weeks, half of the rodents will return from space and land in the Pacific Ocean off the coast of Baja, California."

Dr. Eric Ting Kang first discovered the NELL-1 protein in 1996 and, "NELL-1 has a powerful effect on tissue-specific stem cells that create bone-building cells called osteoblasts. When exposed to NELL-1, the stem cells create osteoblasts that are much more effective at building bone. Furthermore, NELL-1 reduces the function of osteoclasts, which are the cells that break down bone."

Well, no, there really isn't. You say Webb produces data 'without intervention by a human', and 'a huge amount of findings [are] produced by an algorithm'. That's a really weird way of putting it, because the vast majority of Webb time is obtained by individual projects designed to look at specific things, with dedicated analysis plans. Of course there's a nonneglible amount of bycatch, so to speak - but that's not what I read in your comment.

Very fair and true. There are some of the world's most brilliant people doing that work, history making stuff. I wouldn't want to diminish their effort. At the enterprise level, in terms of how tf do you build a space company when at the time there weren't too many examples and virtually no examples of non-major-contractor launch providers, especially with an indigenous system. The fact that she took them through that totally unknown terrain, giving the rest of the brilliant minds the runway they needed to create something wholly new, that deserves a lot more public attention than perhaps she gets.

But again, I agree with you. It takes a village of geniuses.

Yikes, there's too much to unpack here but I think what you're referencing is the images that are created from the archive. Are you familiar with the 3 stages of the pipeline?

Remember too, there are 10 detectors in the JWST, and the limit in the SSR is only 65GB, so much of the processing is done on board to reduce data excess. Tons more info can be found here: https://jwst-docs.stsci.edu/jwst-general-support/jwst-data-volume-and-data-excess

More info on the data pipeline can be found here: https://jwst-docs.stsci.edu/jwst-science-calibration-pipeline-overview/stages-of-jwst-data-processing#:~:text=The%20processing%20of%20JWST%20data%20goes%20through%203,%28slope%29%20images.%20Stage%202%20calibrates%20the%20slope%20images.

Also keep in mind JWST does thousands of exposures using many of the instruments. That data is accumulated in the SSR and is streamed every 12 hours or so to earth.
