Spacescifi

They are a designer made race, created as one of many iterations of a kind of ubermensch... using science. Humans were used as a template... with extra abilities added on to create the OP. So lots of iron eh? They would both weigh more and be slower than a human of equivalent size. Likely tire quicker too unless they eat foods nurtient and energy rich enough to compensate.

I just wanted to know what science and physics would allow for, so those that know would be helpful here. Imagine a scifi humanoid with small suction plates on fingers, palms, and the soles of their feet. Since I am fully aware other methods of adhesion won't work well if at all, what if the suction plates were electromagnetic? Strong enough that an adult of average weight could climb ferromagnetic metal surfaces without slipping or falling. And since magnetism and electricity are related, they could also use static shock but at high enough levels to incapacitate or even kill. Main question: What features would a humanoid body need to have to generate such power as well as survive it? How much power would they need to generate to allow them to generate enough magnetic force to stick to metal surfaces as well as incapacitate people with static electricity via touch via suction plate? How plausible is it? Or is it simply not at all... or would it require a non-humanoid creature?

It's non reactive, inert with several things... barring LOX of course. Hmmm.... would a sort of uses would abio-gel have, as we know biological processes can make methane? Or how about an electronagnetic gel? Would that have any uses... rocketry and besides?

Are Gel Propellants The Future? Imagine if you will, a gel propellant that had a greater density of chemical propellant than liquid? Would it be competitive with liquid propellants? Or would it only have niche applications? By competitive, I mean using gel propellants for 2 stage to orbit launch systems... and maybe even SSTO's. One crazy idea I had was what if it was possible (is it?) to make a propellant gel that ALREADY has the oxidizer 'baked' into it, and only needs some heat applied to combust it? Like a methalox gel? Just heat it and you are good, no need for separate oxidizer and propellant tanks, just a single tank, heating elements in the combustion chamber, and fuel injectors.

That is unfortunate and sad. Prostate cancer is something that can be encouraged by eating regularly from red meats, fatty foods, high sugar content, and alchohol. To discourage it feed on brocolli and other cruciforous veggies, eat low sugar if at all, and low fat, and a variety of fruits and veggies. That's the best I can do for any one here... since nobody wishes to get that disease. Regular exercise helps too... recycles the blood flowing through your veins... like a human oil change.

Money supply is effected by UN sanctions. Civil unrest, literal wildfires... I could go on. In theory Russia could do a lot. Physics and science allow for it... what stops them is always people. From within and from out. Because who is going to spend the same amount of resources competing with Musk when you have more pressing 'wildfires' all around to quench... or at least attempt to?

While the Challenger disaster was tragic... at least sometimes the school of painful experiences forces mankind to refine technology so they don't die using it. Several common things in use people died using in the begininng attempts Aircraft. Submarines I think... X-rays... sure there are plenty more.

Without any bias, the facts are: Russia will defintely lose a certain degree of space dominance if Elon's system works as intended... so it should not come as a surprise if any dislike Starship while they are stuck with less funds for playing KSP IRL. Until another nation can and has the will to commit a similar amount of resources to do something similar to Elon... this whole conversation is simply an unrealistic scenario... that requires peer rival nations with USA abilities. It is not as if the USA has a peer rival for sheer supremacy in resources and power projection, and by the time any nation does the USA will either have surpassed their current strength or have ceased to exist. Because power management is not static... it's fluid. Rivals love to poke jabs at each other, but it does not change the reality of the situation at hand. Surpassing a rival leads to snippiness from the surpassed rival, and bragging rights from the upsurper. On and on. This is per the usual in human history BTW. https://www.cnn.com/2021/09/07/business/russia-space-dmitry-rogozin-elon-musk/index.html

What if it was Godzilla versus... THE MOON! What then? Or better yet.... BATMAN versus the moon (as in memetic with prep time Batman)? People would watch just to see how in the world he pulls it off... because the rest of the league are on vacation for some reason LOL.

Even so... so long they stay funded... I believe they can definitely build and fly their rockets successfully. Why? I have faith in German work ethic... which has international renown. They still have that after WWII, and they are capable of putting it to rocketry uses. Afterall... remember where Russia and the USA found a lot of the technology for the stuff they currently use? Germany. Again. Never underestimate the Germans. I reckon Elon probably knows... but he is busy with you know what LOL. Bezos is also busy... in a different way. Peter Bec-who the world is Peter Beck?!

Do it. Look up mods currently online. DO IT. I mean ask the mods

I dunno man... if I found out my future potential wife used her mouth to.... clean.... I would dump her right then and there LOL. No I am not getting graphic.... since you know what I mean about cats. Suffice to say I read an article where an owner saved a runt of the litter (mom left it to die). Cat likes being cared for and alive, yet momma cat evidently never taught him how to clean thy self... since the cat tries but does not get all the uh... gunk. Thus cat runs around with a dirty posterior that the owner has taken to cleaning... against the cat's wishes. Lately the owner says he figured wiping a fish meat on the cat's rear is the only way the cat will be clean itself thoroughly... because fish they like. Thus cat is happy and so is the owner.

Just curious. Cat's lick their own... parts. Both of them. So I presume: Owners don't let the cat's mouth touch their face (since it's been unclean places including dead or dying life or it's own excrement) If the cat grabs your food with it's paw the cat more or less can keep it since owners are scared about cat germs on their food. Cat's are not aware of these reasons, but are aware that they can use the situation to their advantage to steal and run off with your food if you're not looking. Thoughts? Facts? No I don't have a cat, so I don't know how safe owners actually need to be.

I will paraphrase what Elon is fond of saying, do not optimize what should not be optimized in the first place. You are trying to fix what should not be or cannot be fixed. If you are writing scifi then you are limited to making stuff up if you don't want super long travel times. Also, high thrust constant acceleration, while a possible means of WMD, can easily be countered with the exact same thing. Or engine auto-shutoff when speed gets too high, or a bomb that goes off if you tamper with the engine Most often to do FTL writers rely on tropes like hyperspace, warp, and jump drives. Adding their unique quirks or simply copying and pasting what others have done. Me? I tend to look at video games for inspiration, along witj my knowledge of KSP and current physics.

What do you think? Say what you want about Bezos and BO, but compared to Star Citizen the game in development for a decade if I am correct, Bezos MAY be closer to actually acomplishing his goal. And I reckon surely Spacex will land on the moon before Chris Roberts finishes his decade long project.... that is arguably easier anyway. What do you think?

Fun fact. Marie Curie likely died in the name of science, her husband too, based on cancer symptoms from radioactivity. Science we know always comes at a price for the first ones who do not know what they are dealing with. Learning the hard way through experiment tests... (experience too). Daughter died of leukemia, which if my medical terminology is still intact is white blood cell cancer.

He didn't even dignify Bezos by spelling his name right (You can't tell me that was a mistake, Elon). That's cold man... especially given some of the definitions I saw for besos. Not saying it's Elon's intention... but if so he's being subtle about it. I will give him the benefit of the doubt and assume it was a typo..... always hope for the best in people they say!

The real irony is when I simply play for fun.... gaming can be fun. Like yesterday I played Oolite with the basic starter ship,, zero upgrades, and flew it on a basic starter trade mission where you will get ambushed by FLEETS of pirates. If I was trying to level up I would be upset. But instead I simply bobbed and weaved and yawed a lot, trying to see if I could somehow fly all the way to the planet (ten min away the way I was flying with a fleet literally on my tail) I took some damage to my thrusters from laser beams, and I even laughed when they finally, as if frustrated, fired a missile at me about 6 minutes in. It hit me but I survived still (do less damage if you don't hit them head on and are running away with near full shields). I ended up dying trying to use an asteroid for cover by crashing into it because I could not pull up fast enough at high speed. Nonetheless I had fun laughing at the CPU's poor aim skills. If not for the asteroid I would brought the entire pirate fleet to the home station where galcop would have intervened anyway and likely kicked their butts. While I would still be laughing. I sold all nearly all my weapons anyway, so that's why I was laughing at those CPU's. As it was some of their ships were literally fast enough to fly ahead of me. Stupid AI LOL.

Thanks... it's alright. Assuming Zubrin's NSWR even wirks if we ever test it... we could always put a NSWR inside of Starship and second stage it to orbit. That's brute forcing it... but in theory, besides the Orion... also best we can do.

Wow.... guess we do not even need fusion rockets with their impossibly hard to control magnetic fields. If Nuclear Lithium Saltwater Rockets (NLSR) works as advertised, since it has never been built or tested, but at least it seems a lot more reachable than pie-in-the-sky-slipping-plasma-out-magnetic-fields-fusion. Plus it looks less like NSFW, so that is also a plus... because NLSWR! According to this data below, a lithium saltwater rocket causing nuclear reactions could be a proper torchship.... as in doing 1g for 16 DAYS before running out of fuel with a ship with room for 5, and about 30,000 kilograms of lithium salted water. Here neutrons are focused into a central tube through which water passes. The water moderates the neutrons passing through it. A beryllium reflector keeps the neutrons in the reactor. Lithium-6 Deuteride suspended in the water absorbs the neutrons and supports Jetter Cycle fusion. Helium gas, neutrons and steam are the only exhaust products. NSWRs share many of the features of Orion propulsion systems, except that NSWRs generate continuous thrust and work on much smaller scales than the smallest feasible Orion designs. A single stage system I described previously, with one crewman and five passengers seated in a capsule beneath a 30 cubic meter propellant tank, would mass 1,585 kg and carry 30,000 kg of water salted with 6LiD (mass ratio of 19.9), passing through a high neutron flux region to produce controlled thrust. With a 4,700 km/sec exhaust speed, the vehicle is capable of achieving (a delta-V of) 14,062.86 km/sec! Enough for a one gee boost of 16.6 days!! With 4 days of boost combined with 4 days of slowing down the ship can cruise at one gee a distance of 1,171.28 million km (torchship brachistochrone trajectory). This is sufficient to fly to any celestial body out to Jupiter and back. Reducing acceleration after planetary escape to 0.416 gees increases boost time to 10 days per leg, 40 days per round trip, and increases range to 6,075.15 million km. This is sufficient to take us to all celestial bodies in the solar system, including Pluto, Haumea, Makemake, and Eris.

In less than a month such a ship could do a 'grand tour' of all the planets out to Jupiter. On 24 July 2014 The Grand Tour would be: Grand Tour Dist Days Earth⇒Mars 170.6 3.05 Mars⇒Venus 330.7 4.25 Venus⇒Mercury 64.8 1.88 Mercury⇒Jupiter 780.3 10.14 Jupiter⇒Earth 939.8 11.12 TOTAL 2286.20 30.44 All information from: http://www.projectrho.com/public_html/rocket/enginelist2.php#lswr Here is some criticism of the idea though: This idea needs a pretty large tweak because lithium hydride, however many neutrons are in it, reacts violently with water and most organic solvents, and it's basically insoluble in the few it doesn't react with. It's soluble in a few molten salts: LiF, which melts at 845°C, LiBH₄, which melts at 268°C, and LiH, which melts at 638°C, so this would require high flow molten salt pumps. I get that it's not all that sexy to do, but having a quick browse of material safety data sheets can help steer you clear of embarrassing mistakes. 5mo Adam Crowl How do you avoid a fission blow-torch carving holes in the ground? And, of course, vapourising the vehicle on the launch-pad? Some fancy energy direction is required, as well as some heat-flow analysis.

I saw Lithium NSWR, but I wanted to know more. Supposedly safer than NSWR, but not totally? Is it: Safe enough to launch in an isolated area on Earth? Reasonably as possible to make (not harder) as original NSWR? Where can you mine lithium ISRU in tge solar system? LOL sevenperforce seems to know about this.... years ago.

Magnetic fields slip stuff through, great for nozzles..... absolute containment? Not yet Who knows when or ever. And hot radiation will not care about magnetic fields and still heat stuff, which is fusion more or less. Merely amping the power on solid electromagnets has limits (they will break apart eventually, coils). Perhaps the future electrosupermagnets will be fluid or flexible materials that won't break when amping the magnetic force beyond 500 Tesla?

One more prediction: 5. Higher energy propulsion would allow for things that would not be practical or possible now. Imagine a 2 stage spaceship with a booster that flies straight up, wihout even curving for a suborbital trajectory. It detaches and fires upper rockets atop it downward from the second stage.... which is a project Orion vessel. The orion flips over with RCS and engages the bomb propulsion via the plate and pistons for orbiting. Disregarding all the reasons why it is a no no today... what if we found a way to make sufficiently powerful bombs that were also small enough so the Orion did not have to be any heavier or bigger than say... Spacex Starship? Just because nukes and antimatter are all the rage does not mean other forms of condensed energy storage could be found in the future that may either be easier for storage or more higher energy still. It does not have to be a nuke bomb or an AM bomb per se. If we ever manage to make metastable metallic hydrogen we could use that for SSTO's... at the expense of leaving a crater at launch or landing. People say the engine would melt, but honestly why not just scale up the combustion chamber and engine enough so that it won't melt? I guess because the extra weight negates the the high TWR and high ISP. And lightweight materials that are strong enough are expensive. Alternately MH bombs could sub for nukes or AM in atmosphere. Hopefully alternative to nukes and AM is found in the future that either stores energy more efficiently or is easier to handle.

Far Future Spaceflight Predictions 1. So long we cannot defy gravity by outright negating it's effects, two stage to orbt or more will always be in style. 2. The more advanced spaceflight becomes, the more energy will be required for it. 3. Advanced spaceflight will never, ever be not potentially be very dangerous to all involved in it. 4. If heavy SSTO's ever do become a reality using their own power, if they are using either rocketry or bombs for thrust then they will wreck the launch site and maybe even radiate several kilometers. One more reason why two staging is preferred even if you can do better. Launch boosters can be optimized for launch,while uber space engines are best used... in space. You may share your predictions too...

There is no such thing as fake stress. There are varying degrees of stress. Extreme stress will often mean ignoring gaming, but extreme stress is often a sign of procrastination anyway. Too little. Too late. Better to not wait for high stress to motivate.
