We already knew multiple star systems were extremely common, no?  I learned that in high school, if not earlier, and that textbook still had a full page spread of what an artist imagined would be Pluto.

Binaries would be the most common multiple star system as once you get above that, having a stable system gets more and more complicated to maintain.

Well if he had a very good telescope/sensor array/Jedi MacGuffin he could.

I'm more interested in what long term stable planetary systems are possible with binaries, what the habitable zone would look like, and what kind of climate variability planets would have.

Even with a tight binary pair acting 'more or less' like a single star, I can't imagine that kind of mass wobbling around would lead to conveniently circular orbits for planets.

What i find interesting about these "3d printed" homes is that we are doing nothing we could not have been doing with concrete already for the last several hundred years.

If concrete construction was good to do as piled up thin layers like that, pretty sure we'd already been doing it/seen examples of that from somewhere in the past already.

All i see here in this is basiaclly a bad "remix" where someone noticed that 3d printers squirt out layers of liquid that solidify to make larger shapes.
And they noticed concrete was a liquid that beceoms a solid to make larger shapes too.
And they thought, what if we used that 3d printer thing but with concrete?

But it does not appear that they took the time to find out why it was we have not just been building like that in thin stacked up layers in the first place?

I mean we seen the icing squeeze bags in kitchens already long time ago, and easily could have been using calorie powered versions of squeeze bags of concrete to build in thin stacked up layers like this at any time in the past.

Did we just fail to imagine that all this time already, or is that maybe bulling in concrete like that is not really making best use of the material properties of concrete?

Not that i actually know about those properties, but i do easily see that this methodology of using it has been an option for us practically sense the discovery of the material. So i find it pretty easy to imagine that some concrete experts somewhere in time likely already imagined trying to use it this way, and we don't see us using it in this technique, even though it's been an option for us all this time really.
