Physically and medically impossible


SPOILERS!





Why is this still acceptable to have an bionic arm or leg to give super powers that would require the same strength in the connecting body? In the main characters case, his pelvis would break and tear itself to pieces, or the bionic legs would rip off if he would exert too much power with his bionic calf muscles. It's simply impossible and doesn't make sense!

The same for crazy arms, he is basically wearing METAL GLOVES. So if I put on metal gloves, how then am I able to smash a column of concrete, since all the strength would have to come from my arm, shoulder, spine and even legs to exert that kind of force?

And while we're at it, even if the main character still has genitals, how in the world doesn't he have "scrambled eggs" after running like 100km/h? Or why isn't his head bashed in after running through the glass in the end?

Even for a science fiction, you should get fundamental physics and logic right. I'm surprised no one complains about this, because I'm incapable of suspending my disbelief when watching stuff like this.

Otherwise, it was not a bad film, but stupid writing is stupid.

reply

Even when I was a kid watching the Six Million Dollar Man this sort of thing bothered me. Steve Austin had bionic legs, a bionic arm and a bionic eye, but the rest of him was human. So how was he able to jump off a tall building or lift up a truck without breaking his non-bionic spine?

reply

Because the bionic legs absorbed the shock. Same way you can crash a car at 100mph and come out unscathed, whereas if you're shot out of a cannon unprotected at 100mph your chances will drop considerably.

I give to you a real exoskeleton leg addition that reduces the legs power need by up to 24% (whitch means that if he were to kick something at 24% more power his legs could stand it because the exoskeleton would be the one absorbing the power.

http://biomech.media.mit.edu/portfolio_page/load-bearing-exoskeleton-for-augmentation-of-human-running/

This is completel possible and purchasable with current technology.

He had ALIEN TECHNOLOGY, which in order to travel to earth and do what it did had to be significantly more advanced. if we can increase the poewr by 24% NOW, imagine what we could, in, say, 1000 years?

Thanks for the link, quite interesting.

But that doesn't really address my point, of course it's possible to create an artificial limb that is many times stronger. The problem is that if your hip bone isn't replaced, too high forces would rip your unaltered body parts apart. Or that just replacing your hand would enable you to punch through concrete.

It might be nitpicking but it's just one of those things that make me go "nah that's not plausible".

reply

well yes, without some spartial dampener inside it would still reside to another part of the body, however once again, alien technology, may as well have kinetic dampening inside.

another thing to remmeber is that this seems to have all happened inside a simulation. this would mean that he may not be actually punching a wall, just thinking he did.

---------------------------------------------

reply

Yeah a kinetic dampening field would be about the only thing that would make this possible. But I think with a dampening field (or a simulation) a lot of the themes of the movie don't make sense, especially the idea of fusion between the human body and alien tech. And if it's about exploring human psychology it would seem far fetched that the humans are actually "virtual clones".

I still like the movie and thought it was quite interesting, but I wish it was just a little more "plausible" and thought out and not so fuzzy around the edges :)

reply

I agree that with simulation the fusion theme is out of the window, however we clearly see it is a simulation at the end, so theres that.

oh and i dont meant that humans are virtual. i meant the world is a simulation. they may think they rammed the door down, but what they did was kick air and some light show changed, ect.

I do agree that breaking physics without explanation can take you out of your immersion, however since i always fantacized about such powers myself it didnt do it for me, even if i know its not possible with known technology.

reply

Hehe. If you fantasized about stuff like this (like we all did lol) check out the book "Old man's war", it's an amazing hard sci-fi story about some folks becoming super human.

I don't agree with it being a simulation in the sense of a light show. IMHO what we saw in the movie was material, not "holodeck". When he broke through the boundary he just broke through a big 3D monitor at the perimeter of the "laboratory".

reply

Thanks for recommendation. Love Sci-Fi and will check its availability when at home. Though it may take a while, i kinda got way more stuff to watch/read/ect planned than i got time for them, so sometimes it takes a while to get to something just added to "The list".

Well, i can see the simulation being that way too, i guess we interpreted it differently then.

Its just 'fuzzy' for a virgin who doesnt have anything oher to distract them from over analizing a fun sci flick, once you have a girlfriend that you can take to the movies and finger her pussy, you will be able to really enjoy the movie.






reply

With regard to the alien technology, you don't actually know what the bionic legs/arms were made of. It looked like metal, but it could have been a material that was very strong but very light. And of course, as others have pointed out, the whole thing could have been an illusion. Realistic physics wasn't remotely an interest of this film.

reply

I see the point of the OP and completely agree with him/her. This thing (and others) bugs me too, and didn't like the movie in general.

reply

Posts like these always amuse me when it comes to science fiction films. One of my favorites was from the movie Sunshine. A guy made a post claiming he hated the movie because the ship had gravity, when it shouldn't have, and the Stellar Bomb was completely unrealistic, lol. Clearly some people just can't handle fiction, especially science fiction. The idea that everything has to line up with our current understanding of medicine and the universe is nothing short of laughable, especially considering the fact that were still infants when it comes to science and understanding the laws and mechanics of the universe. I guarantee, most laws will be rewritten many times over before we finally get a clear understanding of the laws and mechanics at play in the universe and unlock all of the secrets.

Were not even close right now. If you were to take a football field and make the 1 yard line a very basic understanding and the 100 yard line 100% understanding, mankind would be at like the 5 yard line right now. I honestly feel sorry for people that pull this crap everytime a science fiction films hits screens. People like this just have no imagination whatsoever. The only question I really have for people like this is why even bother watching science fiction films at all anymore? These people know going in that they are going to nitpick the film to death about completely irrelevant crap.

I really do feel sorry for people like this. It would just really suck to be that kind of a movie viewer. Sci-fi is by far my single favorite genre of film and I just couldn't imagine having so many films ruined for such stupid reasons. Oh well, I guess this is just one more thing to be thankful of as I can sitback and enjoy sci-fi films for what they are, Science FICTION!!

Hey I love science fiction movies and I have no problem "suspending my disbelief" for good movies. It's a question of "plausibility" and degree. Think back to the cheesy sci-fi movies of the 50s! It's not so much things that we can't explain that annoy me in sci fi, but things that we DO can explain. In that sense for me science fiction gets more and more "constricted" with age, the more we KNOW about the universe the less slack we can afford.

For example sunshine was a brilliant movie, of course until the "monster" captain. Had he been less superhuman and simply mad, the movie would have been an absolute classic. Like this it's a great movie with a flawed element in it.

You wrote that we basically know nothing of science and that "most laws will be rewritten many times". That is simply not true! Maybe that is the difference in understanding of science. Science is not up for debate. There are many theories that are unproven, but many are proven. And that means there is no "rewriting". Of course we do not have a theory of everything yet!

I don't have a problem with telekinesis, since that is fiction, but I do have a problem if someone gets only his hand replaced and now he can smash through concrete. How can that work? It's just "too obvious" just from looking at your own hand lol. Where does the force come from? How do his legs not tear off his pelvis?

Also I did enjoy the movie, just because I criticize it's mistakes doesn't mean I didn't like it at all :) I just wish some script writers would try a bit harder to make sci fi more plausible.

reply

Plausibility? First off, as I said before, mankind's understanding of the universe is infantile at best so to say something is or isn't plausible, based on our current knowledge, really is laughable at best. You have absolutely NO CLUE what will or won't be possible in the future as mankind continues to advance and unlock the secrets of the cosmos. For all we know, there are ways of completely breaking the laws of physics as we know them right now and yes, that includes relativity. Sorry, but you just have NO CLUE and to suggest otherwise really is laughable at best! As long as the characters and story are good, the more outlandish the better in my book as I understand going in that we know next to nothing right now and have no clue what will or wont be possible in the future. Not to mention, were actually talking about FICTION here. How plausible is something like the Wizard of Oz, lol? That doesn't stop it from being the AMAZING film that it is. How plausible is something like Inception? Star Wars? The Matrix? Guardians of the Galaxy? The Avengers? Plausibility, lol. Based on our current knowledge, those films are about as implausible as implausible gets. That doesn't stop them from being HIGHLY entertaining films, as long as you can sit back and enjoy a good piece of fiction, which clearly many people cannot. Plausibility, lol. Thats just another way of saying people have no imagination.

No offense, but posts like these always have been a joke and always will be a joke as they are based on our current understanding of the cosmos, which again is infantile at best right now. We just throw things in to help balance equations. When the mass of the universe didn't add up, we just created Dark Matter. When the expansion of the universe didn't add up, we just created Dark Energy, even tho we have no clue what either of them really are. So basically your entire methodology for deciding plausibility is so flawed that its not even worth debating it.

People like yourself should just stop watching Sci-fi. end of story.

And to say that it simply isn't true that most laws will be rewritten is once again laughable at best. The scientific communities have been trying for years to come up with a single unified theory and it has FAILED horribly. In fact, its been one of the biggest failures in the entire history of science and its because our understanding of everything is so infantile. We still don't understand most of the phenomena that takes place in the universe. In other words, well just agree to disagree. We have a LONG LONG ways to go before we even come close to understanding all of the laws of the universe and how they work together. Were not even close right now and once again, for all we know, we will learn ways of completely breaking the laws of physics as we know them somewhere down the line, which will make even the most implausible.....well, plausible.

Do yourself a BIG favor and the next science fiction film you walk into, just sit back and watch it and enjoy it for what it is, a piece of fiction. Turn your brain off and just let the director tell his story. You will thank me in the long run. Or of course, you can continue to let your HIGHLY flawed ideas on plausibility pollute your movie going experiences. It doesn't matter to me one way or the other as I will continue to enjoy sci-fi as I always have.

Laws can't be rewritten? We have already done so many times.

The law of the Conservation of Energy is a perfect example of a scientific law that has changed over time. It was originally a balance between potential and dynamic energy that was expanded to include chemical, heat, light, and mass. The atomic structure went from the Thompson model to the Rutherford model then to the Bohr model followed by the de Broglie and Dirac constructions. Numerous other extensions that are less publicized have been added since the 1950s.

Newton's Law of Gravity was changed to Einstein's General Theory of Relativity

Here is a good article regarding the possibility of changing our current laws.

http://news.nationalgeographic.com/news/2010/07/100707-science-proton-smaller-standard-model-quantum-physics/

Laws can be rewritten. All it takes is a simple discovery that changes something we thought we already knew. It has happened before and it will happen many more times as we continue on. Just because we declare something a law doesn't suddenly make it infallible as once again our understanding of the cosmos is incomplete. Nothing we know about the cosmos right now is infallible, except maybe some of the very basics like the speed of light and whatnot. Your confidence in mankind's current knowledge is HIGHLY misplaced.

Here is another one for you regarding radioactive decay:

http://www.naturalnews.com/033101_sun_particles_radioactive_decay.html

Again, just because we put LAW in front of something doesn't suddenly make it 100% infallible.

I can say this with 100% certainty, if Hollywood had to abide by what is or isn't plausible in regards to making films....well, Hollywood would be boring as hell. Thankfully, that isn't the case as there are tons of writers and directors out there who actually have an imagination and aren't afraid to make films that push the boundaries in regards to what is or isn't possible. 90% of my favorite films wouldn't exist at all if Hollywood shared your opinions on this matter. They don't and that definitely something to be thankful for!

First, please chill out a bit mate :)

So you disagree that stories should "make sense" in some way? What is wrong with more plausibility with what we know. That doesn't preclude creating interesting stories at all, it just makes it more challenging. Hence it's called lazy writing if people don't work at making their stories consistent etc. Using your logic you can't criticize any movie for anything. And again, I didn't say I didn't enjoy the movie, I just dislike the bionic fubar.

My argument isn't even about the possibility to do something, even if you can do something why do it in a "stupid way"? For example if they "magically" make his hip bones strong and fast enough to withstand the forces and speed and heat that would be created by his stunts, why remove his legs at all? If they can do that to his hips, why not do it to the rest of his body?

BTW, slightly OP but I'm curious now: Do you believe in man made climate change? I'm asking because I'm wondering if you have a kind of "unbelieving" attitude towards science.

reply

Now you are scuking Dick to a smarter man while trying to keep a descent facade, failing at all levels.





reply

Well said. I'm so sick of people talking about what is isn't possible when it comes to science fiction movies.

News flash folks, we don't know everything, we don't even know a tiny fraction of everything.

If you told some one 50 years ago that you would be able to instantly communicate with people on the other side of the world, see their face in real time on a machine with no wires attached it, or use that same machine to pull information, images, movies etc out of thin air in a matter of seconds that person would tell you "that's not possible." Yet here we are doing exactly that, within the life times of those people.

When my father was my age VHS tapes gad just come to the market, now you can fit 100's of movies onto a micro sd card smaller than the nail on my pinky.

My point is: don't going around saying what will never be possible, chances you are wrong.



Herman Goering is a "bit dodgy"?!

reply

Personally, I can go along with crazy science in a movie if it's well thought out and treats the audience with intelligence. The whole "going into the matrix" thing was an example of that. Scientifically impossible (perhaps) but presented in an engaging, thought-provoking way that made me happily suspend my disbelief.

On the other hand, there's stuff like "artificial gravity", which generally serves no purpose in movies other than to save the producers the expense of showing astronauts floating around. It's just a plot device wrapped in technobabble, and no-one bothers to explore the massive implications of manipulating gravity. Why, for example, are the explorers in Prometheus trundling around in wheeled vehicles if science can now control gravity?

The bionic limbs under discussion here are the same kind of thing. It feels like lazy writing (bionic = strong, so sure he can smash through concrete). Either the writers didn't spot the bad science or they thought the audience would be too dumb to notice. Or they just shrugged and said, "Meh, we'll call it alien science. That'll cover it."

You cannot make a perfect film. You have limited resources and time so you have to limit where you put your energy, in other words, what to explain and what to show to the audience. Otherwise you don't have a film. You also have to make the story to go nicely forward so you demote things that don't really matter for the story. Unfortunately in real life those "unimportant" things are a little bit different for every person. It is not about being dumb or about bad science, it is about film making and story telling.

Why is this still acceptable to have an bionic arm or leg to give super powers that would require the same strength in the connecting body?

Just here to say that I seriously feel for you on this. This effect happens all the time in movies, and it's not just limited to body parts either. I haven't found a solution to not letting it ruin your enjoyment, but it's got to have something to do with developing the ability to selectively dumb yourself down at will.

Every time something like this comes up, I keep thinking of the scene in Blade Runner where Roy lifts Deckard onto the roof with one hand. Deckard's weight doesn't affect Roy's center of gravity one bit.

Jonah remembered back to only a few moments ago, his shock and fear of the grenade bouncing around on the floor next to him. It had made his adrenaline levels shoot sky high, activating his bionic limbs' full functionality. As the blast reached him, his fully powered limbs emmitted some kind of force field, for the lack of a better description, that protected him from most of the explosion's destructive power. As the remnants of the blast faded, so did the glow from his alien hands.
When he went outside and walked towards the truck they had arrived in, he felt two powerful impacts in his back. He had been shot! But why could he still move? He should be dead. Maybe his limbs were still protecting him somehow?
He was able to reach Nic and convince him to leave with Haley, while Jonah himself would take care of the concrete pillar that prevented the truck from moving.
Again his adrenaline levels rose as he focused on the task ahead of him and in an explosion of anger and frustration he hit the pillar with all he had. His artificial hand glowed bright as it again emmitted its force field, affecting the concrete on a molecular level. It looked like an explosion but felt like smashing his hand through water. Relieved he saw his friends take off into safety. Time to deal with the guards...

Thanks for your reply, that is actually a rather nice explanation :)

OP: Yes, the scientifically intelligent part of my brain said the same thing as I was watching all this, especially that last scene where he broke out into the "super run" and crashed through the glass, but then I had to suspend disbelief and remember that it's just a sci-fi film and since there's so far and few in between... :/
