as an actual engineer i just feel sad. i should probably feel happy but i like solving problems. fml i have becomea luddite.

If this is true it almost literally means black holes are a way for universes to make children. If we apply Darwin’s principles of the strongest survive this must mean that universes that produce the most black holes are the “best”. If correct, what does this actually mean?

i partly agree, but the fact that those blades cant even be recycled [0] but are instead dug down in the ground after use will probably be an ecological issue relatively soon.

felt like i read that article yesterday. 5 years ago, wow. has any progress been made there?

i believe so, https://en.wikipedia.org/wiki/Maxwell%E2%80%93Boltzmann_dist....

2k years is a long time for gas dispersion in such a "small" volume as the earth's atmosphere. early weather behaviour probably affected the distribution unevenly, but by now it should be relatively evenly distributed across the globe. no more or less in rome or italy. this is, however, as we say in sweden, a "guy's guess".

i guess this also means there are around 10^23 farts in the atmosphere. a quick empirical study just showed there around 10 farts to a breath.

indeed it seems so, i thought all atoms (except hydrogen) had some kind of decay. i thought so called stable atoms still had half-lives of 10^{very large number} years.

isnt the half life of most types of molecules in air far shorter than 2k years? maybe i am nitpicking, but would it not be more to correct to say we are breathing the same atoms as those in caesers last breath?

edit: itchy trigger finger, think i subconsciously wanted to be the first to comment. it is stated quite early that molecules preservation is assumed. still think it would be more correct and just as interesting to discuss atoms, not molecules.

edit 2: quick research has taught me that nitrogen gas, n2, and naturally occurring isotopes do not even have a half life. they do not radioactively decay. til.
