Whats your favorite game EXCEPT Kerbal Space Program?
Spacescifi replied to KSPBaron145's topic in The Lounge
The less time you have the more picky you become with how you use it. For example, years ago when classical music was 'new' to me I gorged on any bit of music I could find. But after listening to much of it I now only listen to what I like, and what I like... which has the most replay value for me is Mozart's piano sonatas... when played furiously like Beethoven. Mozart sounds really awesome when he is played with the intonation I prefer.... otherwise he can be blaise. Beethoven ironically is too much.... more than I can stand. I mean I get it.... recorded music did not exist so lay bare your soul in musical form.... but now that it does.... I prer mundane Mozart over drama queen Ludwig any day. Life is full of enough drama already. -
Magnetic Blood Artificial Gravity.... Safe-ish?

Quick question: What's the first thing that comes to mind....
Spacescifi replied to StrandedonEarth's topic in The Lounge
Beef jerky you say? So long it is sodium nitrate free I am interested! -
You know... the classic vessel that can take off a planet, go to orbit, then lightspeed or FTL jump somewhere else and fly at torchship levels of efficiency in space. In fiction you may see a satelite dish (looking at you Star Wars) mounted on the hull... maybe a few antenna, and that's it. So I am curious to know if that is even accurate at all. It goes without saying that when flying into atmosphere from space you would retract satelite dishes and any other long extending greebly bits to avoid the air damaging them from friction. Because visual scifi has well covered what weapons and engines may look like... but sensors? Hardly.

Magnetic Blood Artificial Gravity.... Safe-ish?
Spacescifi replied to Spacescifi's topic in Science & Spaceflight
What you are saying is the acceleration would not be even but rather that it would increase at the toes near the floor and decrease on the way up? And I mean using magnet levels we can actually reasonably achieve. I mean literally pumping the blood with iron particles, enough that a body can be magnetized. A long time ago as a bored teen I managed to magnetize a bug with iron rust. So much was on him that it became trapped inside his joints, and therefore his rear end was literally magnetized. It was kind of fun watching a magnet pull a living creature back as it tried to flee... but I also feel sorry for it.... died for science (repeated slamming into a magnet is lethal). -
Just curious if it would be possible to magnetize blood by increasing it's iron content? Thereby allowing a magnet to induce force on it to simulate downward gravity? Now I reckon nowadays doing that would lead to irreparable cancer risk and damage... but with futuristic advanced technology such could be used in theory to mitigate or even fix any damage done. Main question... I reckon it could work... but one would want to wear electro magnet shoes so they do not get stuck to the floor, or else be forced to turn off the floor magnet. Thoughts?

Ironically hulk almost has an advantage due to having more mass to spread out his waste heat..... which is totally nulified by the fact that he has an even higher energy output than wondy at times. Same result.... a sweaty hulk who would be on the verge of fever death without drinking water regularly or cooling down. And by the way, as dense as both hulk and wondy are, touching them would be like touching a statue, their skin won't budge unless THEY poke it themselves. By the same token if either one fell on you.... you would utterly crushed like a ton fell on you. Sadly..... a super like this could never enjoy a massage.... unless it was done by heavy machine designed for massage. Nor could they use chairs or cars or.... anything designed for normal people... they woukd crush all they sat upon. Their life would require a lot of catering to their.... special needs.

It is always both interesting and amusing what reality dicates when science is applied to any movie superhero. Here we will discuss her.... or rather the character she portrays since she is obviously OOC here lol. According to her wiki online: 1. She has greater endurance because her muscles produce less lactic acid. Reality: This would probably do more harm than good overall.... they could have said she just does not tire quickly and they would not have had to explain why because she is Wonderwoman after all. https://www.medicalnewstoday.com/articles/326521 2. Her muscles and bones are more dense. Reality: She would be heavier. And if going by any of her feats in the movies.... I would say she she weighs quite a bit given how strong she is and the muscle power/density actually required to pull off any of the feats she does. Without any calculations I just know the answer is.... a lot. Based on that... Wonderwoman probably weighs a ton or more. This also means her body would struggle to get rid of waste heat, which means she would be sweaty all the time.... at least any time she is doing superhero stuff. She would also be thirsty especially during and after doing superhero stuff. She would run the risk of death by fever if she did not drink enough water or cool down otherwise when overheated.... which for her would occur EVERYTIME she became Wonderwoman. Combat: Wonderwoman kicks and punches bad guys and sends them flying in the movies. Reality: Given how absurdly dense and heavy her muscles and bones would need to be to do what she does, and how much energy output she is putting out... lets just say that a punch or kick from wonderwoman would be... messy. She would both pierce and obliterate stuff that any normal human would only knock back with a hit. Conclusion: That actually applies to most superheroes who have super strength/speed. Funny thing is that more classic fantastic powers like flight etc would tax the body less... since those do not require any input beyond a desire to fly or use them. Conclusion: You really cannot have realistic superheroes fighting bad guys without them turning bad guys into pasty smears. All those movies would be rated R.

totm aug 2023 What funny/interesting thing happened in your life today?
Spacescifi replied to Ultimate Steve's topic in The Lounge
I have know that knowledge is power. It is also potential... to change the outcome of a given path. As such, I am an avid researcher... especiallly when it involves my wellbeing. Certain foods I usually avoid despite how enjoyable they may be... like cured meats because of the sodium nitrate that increases cancer risk. Interestingly there are ways to make the same meats without sodium nitrate to reduce the cancer risk, but it would cut into profits because the process takes longer and the taste is different too. So money wins per company profit demands at consumer expense. But as the consumer you can be or choose what you want... so long you have the knowledge. It makes me marvel that some... likely a lot more than that are oblivious to the dangers I don't ignore. For example, I desired to try out bangers and mash at the only local restaurant I know that serves British and Irish cuisine. But I called ahead to see if they had sodium nitrate. The waitress on the phone did not know and began asking others but I overheard her say "Sodium nitrate? What's that? I don't know what he is asking for?" Within less than a minute she returned to tell me that yes, their bangers do have sodium nitrate, so I thanked her and hung up. Ignorance is not bliss... especially when knowing can save you pain, suffering, and possibly death. I know several relatives who ate bacon every morning who now have intestine issues and or tumors. -
Bad science in fiction Hall of Shame
Spacescifi replied to peadar1987's topic in Science & Spaceflight
I was watching Transformers 3 because it was being played in a Mexican restaurant. Anyway any suspension of disbelief I had disintergrated when I noticed enemy robot hover craft was using what looked like vectored jet thrust to hover. Problem was that none of yhe exhaust effected it's environment. The most telling moment was when they were hovering over the water with jet exhaust.... no disturbance whatsover in the water, whereas in real life any jet exhaust vectored toward the ground or water below will DEFINITELY disturb the surface of either, especiall given how low they were hovering. Even helicopters disturb surfaces on landing but jet exhaust won't? Come on. -
Things Adult Men Do That I Don't Understand...
Spacescifi replied to Spacescifi's topic in The Lounge
Something less egregious that I don't understand is why men get upset when a football team loses (any team really). If they are losing money on a bet I understand. Otherwise not at all. But then again... I was more a scifi watching, gaming guy in my youth than a guy who watched or followed sports anyway. That said. I always would care far more about a sports game I played than one I watched. Since winning or losing directly depended on me then... to some extent. Probably good I missed the rise of PVP online.... would have been brutal. -
Project Orion: A discussion of Science and Science Fiction
Spacescifi replied to Spacescifi's topic in Science & Spaceflight
Unless we fundamentally change some properties of the exhaust we shoot out of rockets we can forget torch drive efficiency. The higher the efficiency the higher the heat load.... using methods we know and theorized so far. That is why if we change exhaust properties THEN we could have perhaps have higher efficiency. Besides get thrown out exhaust does no work... other than heat. But if it was magnetized.... or repelled magnetically in addition to the normal thermal forces shooting it out... it may add efficiency. Realistically not so much though because we have yet to make high enough lightweight power sources to make that kind of difference. The weight counters the efficiency. So long our battery storage go up dramatically per the weight of the battery, efficiency will always be lacking. It's all about compact, lightweight power.... lots of it. If you have that, any propellant you have can get you farther than with less power. -
Project Orion: A discussion of Science and Science Fiction
Spacescifi replied to Spacescifi's topic in Science & Spaceflight
I am somewhat familiar with mini-mag Orion. It would have to be a second or third stage though, since doing it in atmosphere would blast the magnetic nozzle with an air shockwave. It's a vacuum only drive that uses material that can be ignited for fusion I think, but are not actual bombs... which makes it safer. I think the pellets are compressed via lasers or something to start the fusion blast and the magnetuc nozzle throws the plasma out as exhaust. Mini-mag is good for orbit to orbit but too weak for launching from anywhere planet or moon size. There is a scaled up Mag-Orion with better thrust but I read that the nozzle would be giant. Makes sense I suppose if you are detonating nukes in a magnetic nozzle. That would be more efficient than the standard Orion in space, provided no debris hit and damaged the nozzles from the blast. Ideally the bomb casing would be made of material that would vaporize and not survive the blast... since we only want the plasm from it anyway. Magnets can direct plasma. -
Project Orion: A discussion of Science and Science Fiction
Spacescifi replied to Spacescifi's topic in Science & Spaceflight
I am not per se. But from all the information I have seen torch drives using real physics are actually more dangerous than Project Orion.... especially my version. NSWR is a continous detonating nuclear rocket plume that if any pipes malfunction could go critical and blast the ship like a nuke. And any other alternative realistically has to deal with high energy requirements and consequences. You do not do scifi without high energy. Like Sevenperforce said months ago, in theory there is no temperture limit to a thermal rocket... as long aa exhaust mass flow scales up to take the excess heat away. Sounds good right? The price to be paid is a far greater volume of propellant to compensate.... to take the excess heat away fast enough. Meaning that a torch rocket capable of project orion effiency and thrust would be larger still. I even saw the result if you make a classic thermal torch rocket that can accelerate at 1g for hours The rocket nozzle for said rocket was wider and larger than the Pentagon building! Just imagine the size of the combustion chamber and the propellant tanks! So I do not hate torch drives, but they do not scale down well at all without lots of radiation exhaust. Project Orion scales up well, but a torch rocket really requires even more propellant mass if it can match the thrust and delta V of an Orion. Simply to mitigate the heat. Nothing is free. Radiation or use extra propellant flow to take it away... pick one for a torch drive. Actually for scifi I actually intend for vessels to be able to inhibit gravity so they can float on a planet. So any ship could be an SSTO, but regardless if you use a torch drive or an external pulse drive your exhaust will be devastating. So ascending high via landing/launch rockets is essential, but the grav-inhibitors help since you can float off inertia high up and then engage your external pulse propulsion or torch rocket. So with a direct comparision... a torch rocket that can rival a external pulse propusion will be heavier and larger still, or even more radioactive (NSWR). -
Project Orion: A discussion of Science and Science Fiction
Spacescifi replied to Spacescifi's topic in Science & Spaceflight
Wikipedia says this amount of antimatter is needed for antimatter catalyzed nuclear pulse propulsion; The number of antiprotons required for triggering one thermonuclear explosion were calculated in 2005 to be 1018, which means microgram amounts of antihydrogen.[7] Scenario: An antimatter neutral glass is developed, but it must remain chilled to remain neutral to antimatter, otherwise it will react like normal mass Antimatter storage and production has gone up as well. With such scifi technology... would it not be ideal for antimatter catalyzed nuclear pulse orion and NOT ideal for a rocket that tried to utilize it? I say this because any pellet holding the AM must be chilled, and you would need to control where it is so it does not neat up prematurely snd blow up your rocket combustion tank. Basically, putting a bunch of pellets in chilled propellant is nigh suicidal... since you could hardly control how much energy would be releasd if several pellets go off with the propellant in the combustion chamber. Just seems risky and less controlled. Plus you have to worry about having two sets of rocket nozzles (sea level and vacuum nozzles), whereas you only need the pusher plate with project Orion. So it would seem that, so long pellets containing AM used to trigger a nuclear fusion blast are the basis of the propulsion system, pulsed propulsion is superior to continous. I suppose you could make a pulse rocket, but the thrust would be dialed down compared to the orion to avoid destroying the combustion chamber. Especially with this scifi glass that must remain chilled not to not react with the AM that is within the fusion bomblets. Results: Spaceships would use it, and the funny thing is that they could actually outrun or outlast any chemical based missile at range, which would change the notion of space combat as we may think of it. In fact the only thing that could chase them down at a distance would be other ships using the same tech. -

Spacescifi replied to Spacescifi's topic in The Lounge
I agree when living is rough. When no bathroom is available and no soap either vinegar with water is a worthy substitute. Hot water if you reallly want to kill bad stuff to oblivion. But even cold water and vinegar is better than nothing at all. Water at the very least if nothing else is the most basic cleanser known Vinegar/water mix is good enough to disinfect glass bottles. Only takes minutes. But you probably know that already don't ya? -
On Writing (Novels, Short Stories and Editing)
Spacescifi replied to JoeSchmuckatelli's topic in The Lounge
Thank you much! If any guy can write it's JMS. I think is Bab5 is leagues above DS9, since even though DS9 is good with Bab5 there are far more consequences and a lot of pain involved. The drama and stakes feel a lot more real.... whereas with DS9 they had to rely on dramatic music scores more than the story itself to sell the drama.... which to be honest... compared to the drama on Bab5 was underwhelming. -
On Writing (Novels, Short Stories and Editing)
Spacescifi replied to JoeSchmuckatelli's topic in The Lounge
Wow I watched a bit of it, and will watch more later. "Actions define character." That statement i profound, since writing character sheets has become popular, even standard, and then turningvthe character loose to see what they do in A or B situation. But that is an overly complex way of solving a simple problem. Look at their actions and that tells you who and what they are. It may not tell you WHY they are but the why matters at lot less than who they are and what they do. Who we think we are and what and who we actually are aren't always the same. Note what Major Kira says about judging people, it is spot on. Even IRL on job interviews they ask about your former achievements (actions) because that tells them more about who you are than if you just said who you are. Because actions speak louder than words. I would also say that what have not done also speaks just as loudly. -
This is a parody, but if you had to make both a pg-13 and an R rated version film how would you do it? Interestingly enough and perhaps amusingly an R rating would not be hard. I actually feel sorry for Godzilla. Since if a cat that big retains it's normal strength and agility scaled up then Godzilla is going to be getting slapped and bitten a lot. And when it's all over the cat would be chewing on a very dead Godzilla's face. I have seen cats do it with rabbits larger than them. Cats can be brutal lol.

Actually 30 hours of daylight will make it hot enough that you will likely go indoors at some point or under shade.... and there once more bio-luminescence comes in handy... before tech anyway. And you can forget evolutionary bias since I favor aliens that were artificially built by other intelligent races before them anyway.

Oh come on.... you know sarcasm is his his thing by now. I actually thought of this idea because of my working enviroment. It's often darkened and handheld flashlights are not ideal because you need both to work with. So I thought what if... and the thread! Cats actually see worse in broad daylight (more blurry) and better in darkness (clearer). You will notice their eyes shrink to slits in brightness but expand in the shade or darknesss to absorb more light. A humanoid with human vision and a his own bio-flashlight gets the best of both worlds I think. I kind of said it already in the OP. Their homeworld's day/night cycle is 60 hours long. Having bio-light helps when you are working and living under a night longer than 24 hours. Especially prior to technology. We aee talking 30 hours of daylight and 30 hours of night every day!

It is what it is. On the plus side his genes were good enough to gift me with a certain atheleticism. And with that physicality I will use it to make my life better and brighter than it ever was under him. -

Many kids do that. I had a horrible father and only asked him for help because my mom said he was better at it than her. If your kids actually show that they love you and are not avoiding you because they fear you I would say you have already won. Because science projects come and go. But relationships and what you leave behind matter much more.
