    Still violates the laws of physics

    You and I are in two conventional spaceships traveling at 0.86c relative to each other. In my reference frame, you are traveling through time at half the rate I am. This is due to time dilation, not speed of light delay. After I experience one year on my ship, you will have experienced 6 months on your ship. In your reference frame, the opposite is true. After you experience one year on your ship, I will have experienced 6 months on my ship. This violates no laws of physics, because even though there is no universal “present,” the limited speed of light ensures that causality is maintained.

    Both of our ships have away shuttles with Alcubierre drives. These away shuttles can move arbitrarily fast, far in excess of the speed of light, without ever leaving their parent ship’s reference frame.

    After 60 years, my ship has a cyclospirosis outbreak because someone didn’t wash their hands. The last pilot not suffering from explosive diarrhea hops in our away ship and instantaneously warps some distance in front of your ship (reminder: in my reference frame, you have only aged 30 years). He sends you a message explaining the situation. This message reaches you after you’ve only aged 30 years.

    Swapping to your reference frame now. Causality must be preserved, so since you received that message after 30 years in my reference frame, you must receive that message after 30 years in your own. But in your reference frame, after 30 years of passed, my clock is only at 15 years. You decide to send your own away shuttle to warn us about this future outbreak. Your away shuttle arrives arbitrarily fast, sending us a message about a future cyclospirosis outbreak that arrives 45 years before that outbreak happens.

    You can dress your FTL technology in whatever sci-fi snake oil you want. If you can get information to a destination faster than a photon could, you can break causality.







  • Well nowadays there is “someone else” (for a given definition of “someone”) with a set of controls. Kids are being taught to drive in machines that literally drive themselves, and they need to learn that every decision that the self-driving computer makes ultimately falls on them as the driver. I think they were saying that this is a concept that needs to be taught, not a law that needs to be enacted.

    That’s not to say that a manufacturer is blameless when a FSD car careens into the side of a building at 80 mph. Just that immediate legal responsibility for the movement of a vehicle generally falls on a driver.


  • I’m someone else! I actually keep a running list of shows that don’t include the typical anime turnoffs. No sexualization of minors, and no incest.
