Planetary scientists suggest a solution to the Fermi paradox: Superlinear scaling leading to a singularity

The researchers describe their hypothesis as superlinear scaling—where a civilization grows exponentially, colonizing other worlds until they became unable to sustain the energy demands of their constant encroachment. Eventually, if they did not take action, they would reach a singularity—a point of no return, at which they could not save their civilization from collapse. They note that were it not for the vast distances involved, we would likely easily spot evidence of an alien civilization on the point of collapse because it would be emitting enormous amounts of energy.

• The paper says 'a global civilization will march towards a singularity where energy resources can no longer sustain the trajectory of unbounded growth'. But I can't envisage a point when we can't access unlimited energy.

I favour the idea as put forward in The Three Body
Problem, that upon detecting an emerging civilization,
any existing one will immediately destroy it.

Nobody who does exist is advertising their presence.

Egypt waited too long, did they?

Exodus 1:5 And all the souls that came out of the loins of Jacob were seventy souls: for Joseph was in Egypt already.
6 And Joseph died, and all his brethren, and all that generation.
7 And the children of Israel were fruitful, and increased abundantly, and multiplied, and waxed exceeding mighty; and the land was filled with them.
8 Now there arose up a new king over Egypt, which knew not Joseph.
9 And he said unto his people, Behold, the people of the children of Israel are more and mightier than we:
10 Come on, let us deal wisely with them; lest they multiply, and it come to pass, that, when there falleth out any war, they join also unto our enemies, and fight against us, and so get them up out of the land.
