That guy is who I'm hearing. Agree earth's core is huge as in the size of the moon, Now the moon is slowing down and moving away from earth at 3.8 cm/ year. That creates the tides and also slow down earth rotation. Have fun measuring that inside the earth. Granted volcanism and plate tetonic is an stronger force than tides Quote Link to comment Share on other sites More sharing options...

Russian segment is only funded until 2024, ESA and NASA have received an okay to continue until 2030, nothing has been done on JAXA’s part but presumably they will continue until 2030 too. Nauka is supposed to become part of the ROSS (Russian ISS replacement). For NASA, probably ESA, and presumably JAXA, commercial space stations will replace it. The original idea was to use a modified Progress spacecraft to push it out of orbit. It’s unclear what is going to happen with that though.

Everyday learn something new I think that is not uncommon, you want solar panels for power and it need to be light weight. The common and smaller weather balloons does not but they are designed for pretty short term use. Bu this is more common for huge science balloons.

The suggestion is that initially, these collections may have been just a way for humans to signal those same things. Like "Hey babe, wanna see my hand axe collection? I've got tons of them!"

A bunch ready for the whole tribe to use when they drag home a mammoth? Obsidian is pretty sharp, maybe they used them to shave (j/k)?

Read about that theory before and it makes some sense and don't see other good reasons and people still show off wealth or an illusion of it. Now flint workshops are pretty common finds but then just flakes removed and broken stuff. Many times the only thing found at site as stones break down slowly. But its mind boggling how long hand axes was in use, yes later versions looks better but the idea of putting the ax head on an shaft was late.

Spoiler So, at the special closed NASA meeting it was explained to the JWSTelescope, that his intentions to look more informed in cosmology than the whole scientific community is, and to disprove the basement of the modern picture of the Universe, are selfish, futile, and can significantly decrease the estimated lifespan of the JWST equipment. JWST has promised that he will take into account the community interests, stop showing off with its extravagant results, and adjust the picture of the early Universe to make it matching the theoretical predictions.

Gargamel Posted February 7, 2023 Share Posted February 7, 2023 This is not _quite_ a moderator request, but a personal request from somebody who is a moderator. I do like this thread cause it induces people to post articles that they might not otherwise post. But I also don’t want to see discussion muted on a topic because it’s in this thread. A lot of people skip these threads cause they’re multi topic and somewhat confusing at times. So, using your best judgement, if you think your post might generate some meaningful discussion, however small (like 3 or more replies or abouts), feel free to post it in its own thread. Or if a topic has garnered some good discussion in this thread, feel free to report the original post and we’ll peel it off. And of course, if we already have a thread on a topic, it is much better to post it there than here. And if you do post a new thread, and it doesn’t get the replies, don’t worry, no big deal. These aren’t rules or anything like that, just a small request to see more topics in the S&S sub that have some good discussion. Thanks!

This might be the most elegant solution. It's almost impossible to guess which articles might grab our fellow forumites' attention and imagination. I've dropped stuff in here I thought was cool - only to see it garner zero response and seen things that just seem of passing interest get a page of discussion. But for the most part three to six responses seems like the most an article gets. So maybe we can just do as you suggest and if we discover a topic that merits it's own thread we can break it out?
