      (It got deleted when I edited, so reposting:)

      I asked ChatGPT about orbiting a blackhole. These are the main difficulties according to it:

      Gravitational Forces: Black holes have incredibly strong gravitational fields. To maintain a stable orbit, a planet would need to be positioned at a safe distance where the gravitational forces from the black hole do not tear it apart. This distance would depend on the mass of the black hole and the planet’s velocity.
      Radiation: Black holes emit various forms of radiation, including X-rays and gamma rays, as a result of matter falling into them and undergoing extreme processes near the event horizon. This radiation can be lethal to life forms and could strip away the atmosphere of a planet or damage its surface.
      Tidal Forces: Close to a black hole, tidal forces would be extreme. These forces can stretch and deform objects, potentially causing geological instability or disrupting the planet’s structure over time.
      Accretion Disk: Many black holes are surrounded by an accretion disk, a swirling mass of gas and dust spiraling into the black hole. Debris from this disk could impact the planet, causing catastrophic events such as meteor strikes or intense heat.
      Time Dilation: Due to the intense gravitational field of the black hole, time dilation effects would occur. Time would pass more slowly for the planet compared to observers far away from the black hole. This could have profound implications for the planet’s inhabitants and their perception of time.

      On the topic of light and heat, it said:

      Lack of Light: Black holes themselves do not emit light, as their gravitational pull is so strong that not even light can escape from them. Therefore, any planet orbiting a black hole would not receive direct light from the black hole itself. Additionally, if the planet were located far from other light sources such as stars, it would experience perpetual darkness.
      Lack of Heat: Similarly, black holes do not emit heat in the form of radiation that could warm a planet. Planets typically receive heat from their parent star through radiation and, in some cases, from internal sources such as geothermal activity. Without a nearby star or other heat source, a planet orbiting a black hole would likely be extremely cold.
      However, there are a few scenarios where a planet orbiting a black hole might receive some light and heat:

      Proximity to Other Stars: If the black hole is part of a binary system or located within a star cluster, the planet may receive light and heat from other stars in the vicinity.
      Accretion Disk: The accretion disk surrounding some black holes emits intense radiation, including visible light and heat. If the planet is close enough to the black hole to intercept some of this radiation without being consumed by it, it could receive some light and heat from the accretion disk.
      Internal Heat Sources: Depending on the planet’s composition and geological activity, it might generate its own heat through processes such as radioactive decay or volcanic activity. However, this would likely provide only minimal warmth compared to the heat received from a star.

      ChatGPT may not be good for most writing related things, it is useful for asking about planetary conditions and geological phenomena.

        I don’t know if this is scientifically accurate, but it sounds to me like the planet is super cold, so maybe they can determine the time by the temperature? Like how night is colder on Earth than during the day. The star is still not visible, but rotating on the axis still brings one side of the planet closer to heat than the other. Maybe they have a special frozen liquid in the planet’s natural biome that has to be in a very specific temperature, and if they’re even a little closer to heat, the frozen stuff starts to melt. They could even determine the time by how many drops of the substance has fallen (like a stalactite or something).

        Just spitballing here :]

            @highscribeofaetherium They can count time by whatever happens to be in their sky. You said there’s a moon (or several moons), right? They can count time by that. In one story I had, a computerized “skygrid” was projected onto the sky and brightened/darkened to show the passing of time. Or something such as the tides can show time also, if there’s water on this planet. The moon(s) would gravitationally affect any large body of water in a semi-predictable way.

                      I haven’t been on KP so this is a bit late sorry. So something you should be thinking about for one is do they even need to keep track of time? How relevant is exact time keeping to there experience? What would a culture be like if there was no modular concept of time?

                      Now, if you really just want to have some conception of time, then you can come up with anything. It’s possible that they come up with something innovative, but that goes back to the question of how things worked before said innovation was made, a culture that probably doesn’t have much of a concept of modular time. So if they have a concept of modular time, then it needs to be something naturally occurring. If the moons are visible and cyclic, then that works, but it doesn’t need to be celestial in nature. There’s one tribe in Africa that actually tells time based off of what bird chirps. There’s different species of birds that chirp at different times of day, so they form a reliable if irregular modular conception of time.

                      So:

                      It doesn’t need to be exact.

                      It doesn’t need to be celestial in origin.

                      And it doesn’t need to even be a concept at all if you want to see what such a world would be like.

                      If there is innovation, it should be something that they either really really need for their growing world, or there is a preconception of modular time from some natural source as previously expressed.

                          @anyone

                          If there are any physics people out there, I could use some help figuring out an effect of one of my magic systems.

                          The specific ability I need help with is one that lets a person influence an object or person’s speed through time. You can accelerate or slow it. (These are referred to as positive dilation and negative dilation, respectively.)

                          So, the way I’m playing this is that when you dilate an object, you inversely change its inertia (but not its mass.) So, an object at 2x speed is at 1/2 of its normal inertia. This causes dilation not to influence the actual kinetic energy, because an object with more inertia has more kinetic energy than another object travelling at the same speed. So, if you have a bullet, that is dilated to 2x speed, it moves twice as fast, but doesn’t exert any more force when it collides, because its inertia is only half. (Tell me if this doesn’t make sense. I think it does, but I could be wrong.)

                          My question is, does this impact temperatures? Since temperature is kinetic energy in particles, that should be affected by dilation, but I’m not sure if the change in inertia would balance it out. If you dilate yourself to 2x speed, the molecules in your body are now vibrating 2x as fast. To you this doesn’t make a difference, as it remains consistent with your speed through time. However, would this cause you to start radiating heat into the comparatively cold environment? At the same time, you would start freezing. Then once, you returned to normal speed, the environment would be 2x hotter by comparison to your body, which would have cooled while dilated. If this is how it would work, that is a pretty severe limitation on this power, which might be a good thing, but I’m not sure if this is what should happen. Would the halved inertia of the particles balance out the difference in speed compared to the outside particles?

                            I haven’t been active lately, sorry. Here’s some of my thoughts on this.

                            I think it would be more helpful to think of this in terms of momentum than inertia. Momentum equates to the velocity of an object times it’s mass (which is equal to inertia). So the goal of the magic is to preserve momentum. When velocity increases/decreases, mass/inertia changes likewise to make sure momentum remains constant. You can claim that the mass remains the same, but that simply wouldn’t be meaningful, because if measured, it would have a different mass, even if all the same stuff there. Regardless, this makes sense, if an object was flying, it would slow down if it got bigger, and it would speed up if it got lighter.

                            As for the temperature, my immediate intuition is no, it would not change. Temperature is based off of particles bouncing off one another. A particle with halved inertia bouncing off another particle would still deliver the same momentum, because it hit with twice the speed.

                            Think of it this way: you have a bowling ball that hits a pool ball at some speed. The energy of the first ball would transfer some amount of energy to the second. Now make the bowling ball travel twice the speed, but make it half as big. The same amount of energy will escape into the other ball. Thus your body will remain the same temperature.

                              So, from my understanding, mass and inertia are basically the same thing (mass could even be considered the measure of inertia), except in one instance. The force with which gravity pulls on something is directly proportional to its mass, but greater inertia would slow down your acceleration. Since mass and inertia are always the same irl, this leads to everything falling at the same speed. But if you uncoupled them, you would fall at different speeds (but with the same force), which is how changing the speed of time should work.

                              If I’m understanding correctly, momentum would be another way to think about the same thing?

                              As for the temperature, my immediate intuition is no, it would not change. Temperature is based off of particles bouncing off one another.

                              Okay, that’s kind of what I was thinking, since all the other elements of the system seemed to balance out, but I was having a hard time thinking that abstractly.

                              Thanks for your reply!

The force with which gravity pulls on something is directly proportional to its mass, but greater inertia would slow down your acceleration.

But if you uncoupled them, you would fall at different speeds (but with the same force), which is how changing the speed of time should work

                                Ok, so I just did some equation shuffling for a bit, and here’s what I can say. Mass is what determines inertia. When a bowling ball and pool ball are dropped from some height, they land at the same time, because while they have different mass, and therefore different inertial resistance, they balance because a different amount of force is being put on each, as determined by there mass. The bowling ball has greater mass therefore inertia, but for the same reason, it has greater force applied. So in other words, there is no uncoupling of mass and inertia here.

                                The momentum is just the mass times the velocity (M=mv). So when you decrease mass and increase velocity, momentum stays the same. When you introduce gravity however, then we’re not talking about velocity and momentum, we’re talking about acceleration and force, which you also need to work out. Lucky for us, it’s essentially the same thing, just replace momentum and velocity with force and acceleration, F=ma. When mass decreases, but velocity increases, acceleration will increase by the same factor by definition, since acceleration is just velocity over time. So now when you have a ball falling, and you work your magic on it, you preserve the force exerted on it, but it will accelerate faster than other objects, although it will seem to have less mass.

                                Okay, that’s kind of what I was thinking, since all the other elements of the system seemed to balance out, but I was having a hard time thinking that abstractly.

                                Yeah, since we’re preserving both momentum and force, we won’t see anything change in temperature, which will actually be a weird effect.

                                  Okay, yeah that makes sense. That’s basically what I was going for, but that seems like a more scientifically accurate way to put it.
