Here I am trying out many different fonts, layouts, color coding, drawing styles and such for a notebook I want to use for commonplacing. Also watching tons of YT videos on the matter and seeing how could I keep on doing this now that my week holiday finishes and I'm back to hectic working days. Also pondering if I should keep a hybrid method with physical notebook plus using Obsidian(I may actually study my pages while migrating physical to the app) and also wondering whether to use the commonplacing more like a personal curriculum where I deep dive in 8 or 10 things I like or keep it completely random 🤣 Guess time will tell! This is tougher than I thought, I wanted to have this page drawings one towards the top, another towards the bottom and forgot about it, continued writing and ended up with both drawings at the bottom lol. But I also shouldn't plan too much or else I will give up doing this during my working days. Btw you guys inspire me so much, great topics, artistry and imagination in this community!

Hi everyone, kindly bear with me since English is not my first language and I am also an amateur. So I have just watched AstroKobi's 'Could the Big Bang happen again?' video and it left me with more questions than I had before watching it.

So basically DESI was able to measure the 'growth' (?) of the Barionic Acoustic Oscillations (I envision all of this kind of like a tree's trunk growth rings) and apparently the data releases (not super good Sigma tho) says there are signs of DE weakening (?) Because the imprint of those BAOs (that are remnant of sound waves resulting from the interaction of something with photons (?)) froze when the universe changed phases and became transparent (?) and align with where galaxies like to be, and then the measurements of the galaxy clusters and filaments show a growth ever so smaller with time? So this means DE is weakening and the universe expansion acceleration is slowing down? I don't even know how they trace the size of the BAOs every x amount of time, can it be observed directly?

Among the russian doll of questions within questions I have, what strikes me the most is that those BAOs have been known for a while and there's been a mantra for 25 years or more saying the expansion rate of the universe is accelerating, there has to be a strong body of work to support this even if there was no direct measurement/observation or DESI map before, right? So I don't get this 180 now. Could you guys shed some light? Appreciate.

Commonplacing trial and error

DESI data release, BAOs, Dark Energy evolving/weakening and possibly ELI5?
