What's the difference between orchestration and automation?

Source:

https://opensource.com/article/20/11/orchestration-vs-automation

"The difference between automation and orchestration is primarily in intent and tooling. Technically, automation can be considered a subset of orchestration. While orchestration suggests many moving parts, automation usually refers to a singular task or a small number of strongly related tasks. Orchestration works at a higher level and is expected to make decisions based on changing conditions and requirements."

The Big Bang never happened but fusion will?

Source:

https://asiatimes.com/2020/11/the-big-bang-never-happened-but-fusion-will/

"Eric Lerner: Saying that the Big Bang theory is a well-confirmed theory is very much like saying that the emperor's clothes are beautiful. It's something that lots of people agree on because ultimately their jobs and income depend on it. But it's not something that's backed up by scientific evidence.

Whenever and wherever you look at what the Big Bang hypothesis predicts, and you compare with observations, then in almost every single case you get a mass of contradictions. 

This theory – despite its widespread support in the cosmology community – is like Swiss cheese, full of holes."
