    1. I have an issue with the 3 Body Problem

      Warning: this post may contain spoilers

      Alright, a 2nd spoiler disclaimer for those who accidentally clicked it anyway.

      When it became apparent to me that the alien race had sent over two 10-dimensional supercomputers folded into the size of a proton trying to halt human scientific progression in an attempt to maintain its technological advancement while making the travel towards Earth, something doesn't sit right with me.

      Why oh why, if you were a 10-dimensional supercomputer being nearly all-knowing yet having only the capacity to be at one point in time and space to deny or halt scientific progression, you wouldn't just write code to A) make copies of yourself to then B) hack all the systems and possible computers in the world to halt anything and everything and basically just plunge humanity back into the dark ages if not outright spreading a deadly virus that would eliminate us from the face of the earth if we are such a big threat to them.

      And over the concept of lying and then not being able to coexist with that even though you have the technological head start? And why only communicate with a human to figure out about us if you have two quantum entangled super computers capable of overseeing everything and anything all the time anywhere to gather pure 'scientific' data about us as a species.

    2. Ahsoka doesn't really work

      Warning: this post may contain spoilers

      I just finished this show, having waited for it all to come out before getting into it -- other Disney+ Star Wars series taught me the lesson that they are much better binged than watched week to week and I was not wrong.

      Spoilers below

      The endless references to a children's animated show that I have less than zero interest in viewing really drags it down, which is why my main take away as per the title is that it doesn't really work. Most of the premise of the show is finding Thrawn and Ezra -- two characters you have no way of knowing about unless you watched that cartoon. Yet these two characters are constantly referenced and for some reason important, but you're never really sure why.

      It kind of works with Thrawn because there's a mysterious villain type of thing going on. But Ezra? Why do we miss him? Who is he? What did he do? Almost none of my questions are ever answered, even after we find him! Aside from simply being told by other characters that he is important, I am never told how or why. Nothing they say or do makes me care about him. They don't show me anything that makes me want to get emotionally invested in him. And no, I am not watching hundreds of hours of cartoons to understand the context. That is simply too much.

      This show is in a very strange place between obviously trying to cater to a large audience (it is a Disney property after all, so $$$), but it simultaneously can only be fully understood by extremely hardcore Star Wars fans. I consider myself a fan. I have watched all live action movies and shows, even the laughably bad stuff like the Boba Fett and Kenobi shows. That they intentionally mix together animated and live action storylines though -- especially with any context lacking -- is a major misstep.

      I like the Star Wars universe a lot. And while a lot of it is entertaining, it feels very bad to feel left out. It would be different if it was a small cameo or name drop once in a while. But the main storyline gets impacted by this, and it just kind of leaves a sour taste after finishing it.

      I was decently entertained and it had some very good moments, particularly the Baylan and Shin duo was intriguing -- which is ironic as I understand that they are among the only original characters in this show. Regurgitating old canon is not the way.

      7/10. Entertaining but unsatisfying.

    3. Futurama Season 8 Episode 2 discussion

      Warning: this post may contain spoilers

      This thread may contain spoilers.

      I thought it was pretty good! Better than the last episode, we were pleasantly surprised here at house Godzilla. We actually watched the older episode where Kif gets pregnant the night before, so we were very curious to see how Amy would handle everything. Feels were had.

      What were your thoughts? Let your voice be heard!

    4. Futurama Season 8 Episode 1 discussion

      Warning: this post may contain spoilers

      The first episode of the new season is out! What do you think of it?

      I thought it was pretty okay. It was too self - referential for me. It kept making too many "we're back" jokes but they kind of did that the last time they were cancelled and brought back. They eased off those kind of jokes eventually the last time it happened.

      I was worried about how they would handle references to more modern things as "Attack of the killer App" was really painful to watch. But it seems like they handled it pretty decently.

      I'm slow, but it took me a while to realise that Scary Mirror as a replacement for Scary Door was a jab at Black Mirror.

      I didn't think the episode was very funny, but it wasn't bad either. What was good about it shows promise, so I'm hopeful.

    5. Star Trek: Strange New Worlds S02E04 - "Among the Lotus Eaters" Episode Discussion

      Warning: this post may contain spoilers

      The first three episodes didn't quite hit the mark for me, but this felt like proper TOS style Star Trek.

      Starfleet messing up the Prime Directive. A villain who is actually a victim. Spock is challenged on feelings versus logic. The overall theme of exploring the importance of personal memories and the straight forward metaphor of fascist regime controlling the people, didn't feel as hamfisted as I have found some of the other newer trek episodes. It does stand on its own as a well rounded singular trek story. I do however still have a bit of a problem with how newer trek seems to like hand to hand combat violence so much. Feels unnecessary in most cases.

    6. 'Silo' season finale: book reader discussion

      Warning: this post may contain spoilers

      I would like to have a discussion of the season finale and season as a whole of Silo with other book readers who know the overarching plot. Non book readers are welcome obviously, but spoilers will be here.

      Click for spoilers

      Overall I think it was decent and I like a lot of the additions they made. Some of the episodes in the middle were very filler-y and kinda boring. But I wasn't a huge fan of the reveal in the show vs the books, for the screen and especially for the tape. The heat tape is like the determining factor here and they really glossed over it. I'm not sure if I would have gotten it if I didn't read the book.

      However there are still mysteries, I was wondering where they were going to go with Lukas since he got busted in the last episode. Now he's going to the mines??? Who is she going to talk to over the radio now? Also where do the mines go to avoid other silos lol? Although I'm not really mad about the change if Lukas doesn't end up being Bernard's shadow. In the book it was very "hey you random dude, be my shadow now suddenly"

      And what about that mystery door? Are they connected to the other silos somehow? Bernard seemed kind of surprised when Jules mentioned it and said there were many mysteries... I wonder if he actually knows anything about them or not. I was surprised Sims didn't know about the fake helmet screen, but I guess he wouldn't know that if wasn't actually Bernard's shadow yet. I really question if he will actually end up being Bernard's shadow though...

      Overall, would watch season 2. I wanna know what ends up happening.

    7. How do the human-like Cylons work, in 'Battlestar Galactica' (2004-2009)

      First It was mentioned that, there are 12 of them. If one dies there memory is uploaded and another gets activated, I thought it was somewhat like cylo in star wars. later, we see all of them...

      First It was mentioned that, there are 12 of them. If one dies there memory is uploaded and another gets activated, I thought it was somewhat like cylo in star wars. later, we see all of them operating together, so they sync continously or at certain period? I'm wondering how do they actually work, in data sharing/sync scenario?

      PS. My heart weeps for firefly.

    8. The Expanse: Thoughts on railguns

      Having finished out the Amazon Prime series "The Expanse" I'm now working my way through the novels and I keep coming up against a problem with with railguns. Specifically, the way that railguns are used in The Expanse doesn't mesh well with the way they're portrayed.

      First, some background. Ships in The Expanse are generally unarmored. There are a bunch of reasons for this but the short version is "most things that can hit you in space will kill you anyway" and armor adds mass which makes every manuver more expensive in terms of reaction mass. So no one has armor. This is important because it means that ships in the Expanse can get ripped up by something as mundane as a stray bullet from a Point Defense Cannon (PDC). PDCs are... well, they're guns. Regular guns which are flinging around much less mass and at much lower velocities than railguns.

      Thus, ships in the Expanse are equipped to handle impacts but nothing much bigger than a sand-grain moving at a few km/s.

      When we're introduced to rail-guns in the series we're given to understand that they use magnetic acceleration to chuck a 5kg chunk of tungsten and/or uranium at a target at an "appreciable percentage of C." That's much faster than a bullet or any micrometeors ships are likely to encounter. Even 1% of C is ~3,000 km/s.

      5 kg of Tungsten is less than you think. Some back of the envelope math suggests that's about cube about 2.6 inches on a side... which is not big. That works out to an incredible energy density which would make a lot of sense if railguns were routinely being fired at planets or asteroids but, since they seem to mainly target ships, the vast, vast majority of the energy that goes into flinging that slug at its target is going to carry through to the other side of the ship.

      All total we're talking about 488.5 million Newtons of force for 1% of the speed of light. Helpfully, this scales roughly lineraly so long as we don't get too close to C and induce relativistic mass issues, so 10% of C is 4.8 billion Newtons and so on. So, that railgun slug is carrying a lot of energy. At 1% of C it represents 22.5 trillion joules of kinetic energy. Written out long-ways so we can appreciate all those zeros it's 22,500,000,000,000 J. At 10%, we're talking 2.25 quadrillion joules. To give some sense of scale, that means that, at 1% of C, three rail-gun slugs are delivering about as much energy as the bomb that destroyed Hiroshima in 1945. At 10% of C one round carries about 537 kilotons, or about the yield of a modern, city-busting hydrogen bomb.

      Those are absolutely titanic amounts of energy but, realistically, they'll never deliver that much power to a target. After all, a railgun round can only push on its target as hard as the target can push back on it. If the round just punches through the entire ship like it's made of paper, most of the energy stays in the railgun slug as it exits the other side of the ship and you get a neat hole rather than a gigantic flash as trillions of joules of kinetic energy turn into heat.

      And obviously, if we're trying to kill things, we want the latter. The solution to this problem is fairly obvious: you need fragmentation. While it's great to have a tungsten cube all tightly packed together as you accelerate it, if you're shooting at a ship, you want a fairly diffuse impact, especially if we're talking about a 10% of C railgun slug. There aren't a lot of things out there in the solar system which can take 500 kilotons of hate and come out the other side in one piece. Moreover, at the distances at which a rail-gun fight happens, that spread would help ensure that you hit your target. Like a shotgun loaded with birdshot, a fragmenting railgun round would provide a cone of impact rather than a line, making dodges less effective.

      And, as I mentioned earlier, you don't need a ton of mass to make this work. If a PDC round can go straight through a military craft then we can safely assume that a chunk of tungsten with the same kinetic energy will do the same thing. PDCs look rather a lot like the close in weapons systems in use on many naval ships today so we'll use those as a guide. The 20mm cannon on a Phallanx CWIS tosses out rounds at about 1,035 m/s. Those rounds weigh about 100 g (0.1 kg) which gives them a kinetic energy at the muzzle of 53,422 J.

      So, if we could predictably shatter our 1% C railgun round into 421,136 pieces, each would have about the same kinetic energy as a PDC round and be able to hole the ship. At 10% C we could go even smaller and do the same thing with upwards of 40 million shards. 1% is plenty though. Each hull-penetrating piece of our original 5 kg bullet needs only weigh about 1/100th of a gram, which works out to being about 1/100th of the size of a grain of sand.

      Put another way, if the fragmentation of a rail round could be precisely controlled, a target ship would experience hundreds of thousands of individual hull breaches with the mean distance between them determined only by the geometry of the ship and the angle of the attack. The result of this would be either the delivery of a titanic amount of energy to the ship itself as the armor attempts to absorb the impact or, if no armor is present (as seems to be the case in the Expanse) the rapid conversion of the interior of the ship to a thin soup.

      This, however, seems never to happen in the series and what leaves me scratching my head. As a book and TV series, The Expanse does an otherwise bang-up job with hard science fiction. Most things in universe make sense. This, however, does not. We have take as a given that the materials science technology exists to allow the mounting and firing of a railgun on a ship -- there are a lot of challenges there -- but the straight-line-of-fire use of them is a rare problem with the world-building.

      Any fans have any suggestions to help me square this circle?

    9. I want to talk about The Mandalorian, I don't seem to get it

      Some very mild spoilers for The Mandalorian

      I have not been really following Star Wars since Disney took over, I think I saw one or two of the new sequels (they were forgetable) and I saw Rouge One (It's great, would even call it the most Star Wars Star Wars movie)

      I had some time last weeks and I saw Andor and I was just stunned. Good to great actors, great worldbuilding, a bit on the nose but still engaging social critic and themes, an interesting and intense story based in gritty realism while still being very Star Wars. I think everybody who likes science fiction and/or spythrillers should watch it.
      So I was like: oooooh so they finally found a way to do new and interesting stuff with the Galaxy far far away. Everybody says nice things about the Mandalorian, let's check that one out. It got 92% on RT so I'm shure it's nice....

      I seem to hate it and it makes me angry that it turned out the way it did, because i still like a lot about it. It makes me sad that they botched it so badly.
      Maybe having a main character whitout a face is not helping? so i need a robot to tell me what Mando is feeling? Pedro Pascal is actually doing an incredible job working with body language and voice, but I don't think it's enough to actually be able to salvage this dumpsterfire of an realisation. Or maybe they should have kept with Mando being an unrelatable asshole, and not make him a disney daddy?
      And then they still show his face.... in the most anticlimactic way ever... why? just why do that? It makes me angry just thinking about it, how can you fuck that up so badly, that could be a series defining payoff, but no! They just waste it in the most boring and unconcequencial way ever.

      Then there is the Rule of Cool or Why is Everybody a Badass?. Mando is cool, i get it. He has an amazing Look (obviously the helmet is crazy good). He has very interesting and powerful weapons. But then I he still gets mostly his as kicked by nearly everything and everybody all the time?? I mean why do you tell me with every character and all his design that he is a force of nature and than he gets his ass kicked by a fucking dinohead on two legs that looks like a joke and is a joke (I dont actually mind that, i like the design and the joke) I just makes no sense to me.
      Nearly everybody else looks cool and is presented as a badass as well, there is just to much of it. there are no weak people, there are no hurt people, there are just badasses and cannonfodder.

      Then there is the storytelling... It ranges from quite ok to fucking horrible. I mean, who thought it is a good Idea to NOT cut the motherfucking prisonship episode? It's some of the worst TV i saw in a long while. It does nothing for the overall story. it does nothing for the characters. It does nothing for the viewer. It does nothing for nobody. Its just full of bad acting, bad direction, bad and lazy set design, bad editing, bad jokes, and the worst storytelling. why did they leave that piece of shit in there? the whole series is worse for it. It makes me angry.

      So I finally checked the wikipedia page and I understood. Jon Favreau.... Jon Favreau!!! I mean not all of his work is that bad. I liked Iron man and Chef, and I love Cowboys and Aliens (really! it's so bad it's good, but you can not expect differently with that name) I hated his Lion King.

      I don't now where I'm going with this. I think I just needed to share my feelings about it. It's just so full of potential, there is so much they could have done with it. they could have explored so many themes and share so much lore... but they just fucked it up and everybody seems to like it, i dont get it.

      /rant

      so are the other Star Wars shows worth a watch?
