Reply to What if The Universe Has Always Existed by GhostCallOut2

The very idea that time passes differently around black holes is part of Relativity. Relativity implies the universe is not static, I.E it is expanding. The universe having a beginning was first suggested by Relativity. These two things do not work without the other also being true.

They are what is known as a stellar nursery. Inside these pillars of gas stars are being formed in truly breathtaking numbers. Looking up close you can see the young stars shining through the clouds.

Sadly they no longer exists. The light we are seeing is about 7000 thousand years old and in those years they've probably been blown apart by the stellar wind of all the stars that have formed inside them.

The pillars are that "hand" in the middle. It's a famous photo taken by Hubble telescope in 1995. "These elephant trunks had been discovered by John Charles Duncan in 1920 on a plate made with the Mount Wilson Observatory 60-inch telescope"

Usually they're shown more zoomed in(newer photo from 2014) https://upload.wikimedia.org/wikipedia/commons/6/68/Pillars_of_creation_2014_HST_WFC3-UVIS_full-res_denoised.jpg

Reply to Soyuz MS-23 may share design flaw with MS-22 and Progress MS-21. Soyuz MS-24 may launch earlier than planned. by AWildDragon

Anyone who has manufactured complex systems knows that one of the benefits of serial production is that problems tend to repeat until you find and solve the root cause

I'm not saying this isn't a defect their qc system would have caught in the past but it is possible the root cause is some new failure mode the system is currently unable to catch.

I would not berate the Russian engineers until the facts come out

Do recall that we lost two space shuttles, one due to a management error launching when too cold. But the other was lost due to complacency. Seeing huge chunks of ice falling away and no problem resulting from it was a huge miss

I expect engineers around the world do their best on these things. Most really care. The tougher one is management. They are budget and time constrained and often not knowledgeable engineers. It is way easier to make the wrong call in these cases

As an engineer in the US who started out in aerospace, I'm astonished at how well the US and Russian space communities have held together given the world situation. It must be very difficult to collaborate effectively but they seem to be doing it much better than I would have hoped.

I recommend we cut them some slack and let them do their jobs with less heckling. They are all people like you and me.
