For me, fun is taking a program, language, whatever and making it do things it's designer never envisioned it doing. It comes in handy when I'm asked to do something a little outside the norm as part of my job.

comment Water in vacuum (or space) and temperature in space
Given that the triple point of water is several orders of magnitude higher than ambient pressure I wonder how the water could remain liquid even for a few tenth of a second. Does the inertial confinement keep the pressure high enough or is the freezing process that slow?

A simple (and kitchen safe) demo of pulling gas out of solution can be done by allowing clear soda to go mostly "flat" and then using it a in a siphon.

comment Would a directional “graviton” emitter violate any known laws of physics?
@dmckee I didn't think gravitational waves (or at least any kind we know how to make) were any more directional than a simple dipole antenna would be. (See edit)

comment Would a directional “graviton” emitter violate any known laws of physics?
@dmckee Why would it inherently be any more complicated than, for example, a Yagi-antenna? What would require a graviton to be harder to manipulate than a photon? -- Besides, I'm specifically ignoring the practicality to look at the practicability and the implications of it being even possible.

comment Best EM/Photon rocket using avalable tech?
the laser beam might be highly collimated but the waste heat (IR) won't be. Besides, it adds a relatively large mass that it has to accelerate (which might be an issue is your power supply has a high enough specific power).

See user34445's answer: the 'supersystem' is math and logic.

tl;dr; A ToE can exists under Gödel and still 'describe' everything physical but e.g. will not be able to 'describe' things intellectual.

I guess the question devolves to a balance between mass of the device and how well it collimates the radiation. I suspect that a dish would have to be VERY deep to do a lot better than a hot plate and will be a lot more complex.

@BenCrowell countering that sort of things (or more accurately torques caused by them) is the application that got me thinking about this.

comment Best EM/Photon rocket using avalable tech?
I could see how that would work is it was an AC power source, but it raises the question of how efficient it is. I'd expect this becomes a "directional antenna" problem: i.e. the more directional an antenna you build the more efficient a thruster it becomes. The question then becomes is it easier to make an X Watt EM radiator highly directional in the RF band or the IR band?

I'm thinking space (so a box fan is out).
