Well being that the potential black hole is inside a ship, and it was only large enough to affect one person id say it's not supermassive. Smaller black holes are even more dangerous imo. Negative mass/energy? Are you saying something like antimatter, antiprotons etc? The him being killed/scrambled is just a theory to explain why he seems to be slowly losing his mind. Not to mention is seemed like Tyr knew exactly what was happening to him and is refusing to tell him, possibly to spare him. We don't know what the effects on a living being traveling through a black hole to another universe would be. I wasn't going with spaghettification as the reason for him to die, I just didn't word my thoughts correctly. As I know the larger the hole the "safer" it is, it also needs to be spinning as well no? Could also end up being a donut 🍩 shape as well? Small black holes are the human-pastamaker ones. As the tidal forces between say your head and feet if u went in straight up and down is far too great and it can literally break the particle bonds making up your body, no? I'm just wondering if it somehow messed with the actual matter making up his body, right down to the electrons, protons, quarks and gluons. Heck, maybe it messed with the spin of the particles. Maybe it made the particles in his brain or change their handedness? Maybe their universe is predominantly left handed vs right or vice versa and that's causing all sorts of crazy shit? Wormholes while theoretically natural, don't most theorize they would be rather small without "feeding" them in order to increase their size and keep them more or less stable? Yeah this "hum" does sound like what they're harnessing from the hole to use as a power source. My wonder is, would a black hole be easier and/or safer than say, a Dyson sphere or swarm? I know gravity has ENORMOUS potential as an energy source, and it will far outlive every star, even red dwarfs in the universe, no? I'm also trying to understand the gravity well in the penultimate episode. It worked opposite of normal gravity, antigravity if you will. Yet he said it seemed as if its effects lessened the farther away from the center you got. Which would make sense with a black hole, but it's the opposite effect so.......white hole possibly? I've never studied astrophysics or even physics in general, I'm an auto mechanic. So, it's nice to know I got at least one part kinda right.
That's quite a long message but I'll try my best to respond to all your questions, also a reminder that my field isn't astro so there may be answers I do not know.
You asked if by negative energy/mass i was referring to antimatter, and unlike the confusing naming would suggest, they actually have nothing to do with one another, antimatter has positive mass and energy and exists, negative mass/energy is purely theoretical
I dont know what you mean with the black hole needing to spin, all natural black holes spin as far as I know, I also don't know what you mean by doughnut shape, if you're referring to the singularity and the effects of the ergosphere on it then I can inform you I have absolutely no clue what happens there and no one really does.
You also mentioned that Tucker might have moved to a universe with a different handedness/parity, that was a creative idea i haven't heard before, took me some time to properly think about it, it's probably not what happened because a basic change of parity would fck up lots of stuff in noticeable ways.
as for all your worm hole related questions, I have no clue, I know they're natural solutions for einstien's field equations and unstable so would need negative mass/energy to work but no more than that.
You also asked if a black hole generator would be easier and/or safer than say, a Dyson sphere or swarm, to that i say they're both sci-fi, at the end of the day they're both just fictional ideas, so both are not practical at all
It's nice to know that people are that interested in physics, and you know a lot about this subject, but I wouldn't fret about finding an exact physical phenomenon for the Mæron, imo its nicer to theorize broadly, most sci-fi doesn't exactly follow the theory anyway, and to be honest I like it better that way
So, I had a thought. What if the gravity well operates on the theory of repulsive gravity? Einstein's equations state it's possible to have repulsive/anti gravity, and some theorize that's partially responsible for the acceleration of the expanding universe. I'm not so sure about that but, it could work in this case to explain Rhoun's little impromptu experiment/floating session, 😆. Maybe the creation of the black hole 🕳 in the Mæron has a side effect of producing small pockets of repulsive gravity‽? I hate having ADD & ADHD, as I'm constantly thinking about stupid shit like this. I'm not intelligent enough for all this physics. I'm an auto mechanic, I shouldn't be having, or even being capable of these thoughts 😅.
Could they possibly send him to his home universe via a white hole? If we ignore the math saying his universe blinked out of existence the moment he crossed the event horizon and, if they could control or somehow know what universe it would send him into that is. Is there no way to private message on here? Would be nice to converse more.
