I'm trying to help a new user here, but my first try didn't help and I'm about to leave after making my second try. If any of y'all see a way to help an earnest but confused new user, please do.
@MonicaCellio It might be some kind of stretch, but knowing the protocols in theatre when people are sick/giving birth (not saying it's the same, but protocols might be), might somewhat fit the scope... that would not be the most stretched question, IMHO.
However it needs to be a bit more specific, as you mentioned in your second comments, without details, it is far too broad...
@Secret Saw that a few days ago, thought it was pretty interesting, but one thing confused me. So light (in a vacuum) is already going at the speed of light, so why would bending it around a black hole help? Then I got to thinking. if you have a light sail and a laser, mount the laser on your ship, and then shoot it at the sail, nothing happens because the light pressure from the laser cancels out the light pressure on the sail. Also why you can't mount a fan on a sail boat to get speed.
But, if you were to aim the laser out the back, bend it around a really small black hole, and then have it hit your sail, then you'd have the light pressure from the laser and the light pressure on the sail both pushing you forward. But it only gets useful if you can drag the black hole along behind you. But does that violate physics? (aside from having to drag all that mass, even for a really small black hole.)
Also, unless you bring it with you, how the heck do you slow down, unless your destination also has a black hole to bend light around?
The idea is that as the light bends around the black hole pair, it steals some orbital energy thus blueshifting the laser. Hence the light pressure before and after do not cancel out
And the author in that video also mentioned, you need to find another black hole pair to slow down by basically doing the laser thing in reverse direction
Annoyed by some of my questions and those of other people being closed for spurious reasons, I decided to set up two test questions.
The first question
This was deliberately designed to be popular but to be thoroughly story-based. The answers were predictable and were nothing I couldn't have th...
@Secret "steals some orbital energy" queue a period far in the future where millions of ships have used a black hole pair in a popular location, and the orbital energy loss actually destabilizes the system
Also, if you have laser failure, you're suddenly plunging toward a black hole at superluminal speeds without brakes... sounds exciting
From time to time we encounter questions of the form:
What is the earliest time X could be discovered or built?
Examples include:
What is the earliest time a pulsejet could be built?
How early can transparent glass windows be easily available?
How early can nuclear reactors be built?

@Hosch250 Looking at that map that doesn't make sense... but we also don't know what time period was used, the exact trends looks up, lots of other stuff
I think the main point is that google trends can be used to generate mostly meaningless noise without too much trouble, hence the "least informative" label.
Several hundred years after Simon, the Sudoer, Anon and two gold dragons managed to seal him away, Heinrich, the First, formerly Henry, is back, this time with an M249, ready to give world domination another shot.

Next week is the kids spring break, and they are going to the mother in laws for at least half the week, and most of those days the wife is also working until very late, so it's almost as good.
