As I understand the book the answer is that Gargantua isn't a single black hole. Or rather, it is, but there are other orbiting black holes around it. And so the time dilation (and gravity) effects are far more chaotic.
Really? As far as I remember, the movie does not clarify this at all. I'm a bit confused as how it would achieve the particular effects depicted, but again, I'll have to read the book. Now I am even more curious.
You know, I'd love to see how the spacial mechanics work for how black holes 'orbit' each other, as I understand they don't generate a gravitation field in so far as to have a 'orbit' as we'd define it via a planetary body, the only known exception to this really isn't a exception, the binary black hole phenom in which two black holes basically consume each other, and result in a single black hole, all theoretical, to my knowledge there has been no confirmation of their existence beyond if I recall some sort of reading that was detected via deep space radio wave or some such.
But then you have situations like the collector base and multiple black holes that are apparently in a stable 'orbit' as we'd define it, as improper as the term may be. After all black holes rarely supposedly move, but they can move if say a star explodes or some such garbage, which you figure would be a frequent occurrence and yet there seemed to be no shortage of occurring black holes, but they did not consume each other. I tend to play it off as visual effect given my admittedly mediocre knowledge of astrophysics disputes it but perhaps it is possible due to some mass effect universal space magic.
So ultimately I'd assume, from what I know of these little rips in reality, if they are in proximity to 'orbit' each other, they will eventually merge into a singular hole. Unless if you apply some reaper tech apparently.
People have this tendency of thinking that black holes project black hole magic all around, but truth is, outside of the event horizon, Black Hole gravity is pretty ordinary, even if very strong. However, any object following a proper geodesic and with the necessary speed will orbit a black hole just fine, even other black hole. Should the Sun be replaced by a black hole with one solar mass, earth's orbit would go on unhindered, and we would freeze and starve, not be crushed into non-existence.
That's very interesting, thank you. I imagined the whole ''Power of Love'' nonsense didn't have any basis other than artistic license, but the whole timey whimey shtick being rooted in theoretical science is news to me.
I still think the sequence is overly dramatic and overdone (transmitting the magical equation that solves everything in Morse messages in the dust, really?), that said timey wimey location having a direct link to some girl's bedroom is awfully convenient, and that the main character actually understanding what in the blazes is going on while being thrown into something no human being has come close to experience, is a bit silly. Plus I dislike time travel as a plot point as a rule.
I like the movie for what it's worth, but I agree that the dramatic parts are quite lacking.
Sorry, but this isn't totally correct. It absolutely does matter if a black hole is supermassive vs. a stellar mass black hole. While yes, all black holes warp space time to the point of a mathematical singularity (which likely doesn't actually exist, but for the sake of discussion...), the mass of the black hole determines the effect of time dilation at a given distance from the horizon. The effect of it from a stellar mass black hole is not negligible, but comparatively so to a supermassive black hole. Also, paradoxically, it is easier to maintain a stable orbit around a supermassive black hole than it is a stellar mass black hole.
In Interstellar, it is worth noting that their ship wasn't actually orbiting the planet that they landed on. It was in orbit around Gargantua at a significant distance from the planet. The effect of time dilation decreases exponentially with distance from the black hole, that's why there was a difference in the passage of time.
But yeah, the effects are extreme. Thorne deliberately pushed relativity to its limits with Interstellar. But the movie is true to his vision.
I'll go on a limb and say we are not actually disagreeing in anything. Am I correct to assume that you are saying that the size of the black hole matters, because you are assuming that the distance between the planet and the black hole is the same with either? Because if that is the case, I'm on board, and agree entirely.
My point, however, was that it does not matter because every black hole has AN orbit in witch the time dilation would equal to the one depicted. As the objects are both fictional, they could very well have achieved the same dilation on a stellar mass, without changing as much as a line of dialog, as the distance is never described.
That said, it's news to me that the ship was not orbiting the planet. Makes more sense in so far as the dilation differential goes, but opens a second problem, as it makes the concept of a quick EVA in the surface much less feasible.
