I'm still not sure of course whether the emdrive is a real effect or not, but for fun I've written a humorous dialogue about it and MiHsC, so in the spirit of amusement here it is: Kirk, Spock and McCoy travel back to 2014 curious about the early origin of the theories that lead to inertial damping and faster than light travel..
Spock: Captain, I've found some recent references to a theory called MiHsC and an experiment on something called the emdrive.
Captn: Alright Spock, let's have it!
Spock: I'll come to MiHsC in a moment, but the emdrive is a resonant microwave cavity, cone-shaped, that appears to move slightly towards its narrow end..
McCoy: Now just wait a minute Spock, I'm a Doctor not a physicist, but doesn't that violate the old conservation of momentum?
Spock: You are, surprisingly, correct Doctor.
McCoy: Why thank you Spock. I suppose that ends that conversation..
Kirk: Don't bet on it bones!
McCoy: Sounds like another crackpot lead to me.
Spock: I find it fascinating.
McCoy: Why doesn't that surprise me!? But it still violates momentum conservation.
Spock: Doctor, the medical physics courses you took, even in our time, are still based on old 20th century physics and skim over the new physics, but the Enterprise would not move without it.
McCoy: You're telling me they repealed the conservation of momentum now?
Spock: No, but at this time, humanity is still mostly unaware of the momentum obtainable from the zero point field.
McCoy: But this emdrive looks like baloney: you can't make something move without applying some sort of detectable force!
Spock: Indeed you can if you know how. Even in this backward time period that was possible, though the wider potential was not realised until MiHsC was proposed. Are you aware of the Casimir effect?
McCoy: Forgive me Spock, I was busy curing real people while you were devoting your life to inanimate objects and impenetrable ideas.
Spock: Very commendable Doctor, but the Casimir effect is produced by putting two parallel plates close together, so that they damp virtual particles of the zero point field between them, so that more particles hit the plates from outside them than inside, and so the plates move together very slightly.
McCoy: What's your point?
Spock: The system has moved without a 'detectable' outside force being applied to it.
McCoy: Sounds like a lot of goddamned voodoo to me.
Spock: On the contrary, even at this time the Casimir effect has been observed many times and was the first experimental inkling of the 21st century revolution in physics.
McCoy: Well, be still my heart, but if it's only a tiny effect..
Spock: We have a saying on Vulcan: "If a door is slightly ajar, it's wide open"...and there's a theory proposed in this time called Modified inertia by a Hubble-scale Casimir effect (MiHsC) that brought the zero point field and horizons into physics, and also predicts the emdrive quite well..
Kirk: MiHsC, MiHsC! That reminds me, Dr Carol Marcus used to go on about a funny old theory called MiHsC that started a paradigm shift and got rid of the need for something called dark matter and energy.
McCoy: Brings back fond memories does it, Jimmy boy?
Kirk: Bones, as a Doctor you ought to know better than to reopen old wounds.
McCoy: Very funny. I'm sure you've made that joke before.
Kirk: Good work Spock. It could be the beginning we need..
McCoy: (mumbles) Still sounds like a lot of baloney to me..
