It's not a coincidence, it's just physics. Any rotating system like this will tend to sort objects by mass, with the heaviest at the middle. You can see this if you just take some sand and swirl it in a cup with some water. The largest grains will end up at the center. Why? They're the heaviest, and it takes the most energy to fling them around. If we simplify a galaxy to a two body system, you will imagine that a light star and a heavy black hole will orbit each other with the star making a much longer orbit than the black hole, which may be almost stationary. In a galaxy, you don't have a two body system, you have every body in the entire galaxy acting together, and relativistic effects and all that, but the same thing is happening. The distribution of masses in a galaxy broadly follows what's called the Einsato profile, which essentially says the densest objects will have the lowest radius. Of course, galaxies come in all shapes and sizes, and come in various states of development (a galaxy that has just collided with another may have a random distribution) but over time, a galaxy will organize itself with the densest objects at its center.

I'm sure it'll have plenty of impact, just as falcon 1 did, as a technology demonstrator. Really, terran 1 is a demonstration of their ability to print the rocket, stick all the avionics together with their engines, and get to orbit. For them to have any chance of securing the funding for terran r, which actually does take advantage of the 3d printing process, they kinda have to start small. And ultimately, what they're really building here is the ability to build rockets on the moon and mars, which is a big deal in and of itself. Same goes for spinlaunch, for that matter. They're both building launch vehicles with technologies that don't make that much sense on earth, but do make a ton of sense once you get off it.

Because those things are fucking enormous.

Oh that's nothing. A dusty plasma fission fragment rocket can deliver an ISP of 1-2 million seconds, using technology with already high TRLs.

Yeah it's not a damn microwave oven. They're just not going to be that powerful on the ground. You need big ass antennas covering a lot of area to collect the power. Even if you wanted to fry birds with it, it would be a significant engineering challenge achieving that level of beam collimation.

Great now we just need to wait several days for the target to align itself with the orbit at the right time and ah fuck they shot it down

Everyone always forgets Pegasus. And Antares (sort of).
