"Matter has positive gravitational and inertial mass, that is, two objects attract each other, the lower mass faster than the more massive" A part of the law of gravity Newton. But how this applies to negative and imaginary masses? A hypothetical negative mass is a object that has negative gravitational and inertial mass, and therefore negative energy. A negative mass does not act as you think now. Obviously cause a repulsion towards the positive mass by the gravity, but have negative inertia, therefore the negative mass would not repelled by the positive mass, generating a "persecution" of negative mass after positive, that is, an acceleration of the set of masses of zero energy. Also, the negative mass repel itself, and thus a hypothetical negative solid mass tend to expand and disintegrate. On the other hand, an imaginary mass is a hypothetical mass that move at speeds greater than the speed of light and have positive energy, this is result of a squared negative mass, ie, imaginary-valued mass. How moves this? A real mass (either positive or negative), has a idle speed of 0m/s, the speed must always be less than the speed of light (c), and travels relatively to the future. A zero mass does not has repose velocity, always travels at light speed, and standing frozen (relatively) in time An imaginary mass has a idle speed of infinite speed, speed must always be major than the speed of light (more slower more energy required to slow, the reverse of real mass), and travels relatively to past. But how the imaginary mass interacts with itself, positive and negative real mass? I created this topic to disclose such hypothetical curiosities and find some conclusion, share information and delight in the truth.

Self-replicating alien machine? A alien Bracewell probe?

Thanks

Hello, this time I thought a idea for a mod of advanced hypothetical methodes of propulsion, but I can not make this. This is the clasification and short description of each one: Esencial for the mod: - Diametric drive: a type of propulsion that would make use of regulated non-conservative gravitational field with non-zero curl, ie, a similar thing like "gravitational field with two poles", obtaining a zero energy acceleration. - Disjunction drive: similar to diametric drive, but would make use of permanent non-conservative gravitational field with non-zero curl, controlling the acceleration by de distance of "gravitational poles". - Pitch and bias: unlike diametric and disyunction drive, this method would not make use of regulated non-conservative gravitational field with non-zero curl, but would change the gravitational constant back and forth. - Differential sail: a engine that would generating negative pressure/energy (casimir effect) forth of this, and positive pressure back. - Warp/Alcubierre drive: a type of propulsion that would move the space arround the starship instead the starship. Other, not needed and very difficult to make: - Worm hole: two distant points of space interconected, ie, a thing like portal with spheric shape. Note: the non-conservative gravitational field with non-zero curl is hypothetically possible with negative masses (and hypothetical particles) together normal masses, this is, a negative mass would repelled by positive mass (and positive also), but would have negative inertia, and this mean atraction instead repulse, originating a lineal move of possitive and negative masses. New materials: - Negative energy/pressure: a density of vacuum required to make work the warp drive, differential sail, worm hole, etc. New parts: - Negative energy generator: a part that produces electricity to generate negative energy deinsity (only work when there is a receptor, ie, a exotic engine with negative energy storage space). - Diametric drive reactor: a part that works like engine, requires store negative energy to accelerate, more negative energy, more acceleration, until 10m/s^2 (variable per total mass of ship); and destroy negative energy to not accelerate (when destroy negative energy, consume electricity); is slow to change these actions. - Disjunction drive reactor: a part that works like engine, not requires store negative energy, only consume electricity to separate or bring near the two reaction masses; when separate the reaction masses, not accelerate; when bring near the reaction masses, accelerate until 20m/s (variable per total mass of ship); is very fast to change these actions. - Gravity constant reactor (Pitch and Bias): a part that works like engine, not requires store negative energy, but consumes a lots of electricity when change the acceleration, accelerate until 50m/s^2. - Warp drive reactor: a part that works like engine, consume and destroy negative energy when is active, but consumes more electricty than the produced for the generation of negative energy; her work althrought change directly the velocity instead the acceleration, and when not work brake to original velocity. The acceleration by previous methods cancel the G forces. - Differential sail engine: a engine that only consume negative energy, accelerating like another normal engine, with G forces and low power.

Bad news, the page that I based was actually a canard and have removed the page of reddit for this reason. Any moderator could close this topic?

I can't to access now, but I have the link in the record: https://www.reddit.com/r/KerbalSpaceProgram/comments/3vy56f/squad_plains_add_planetary_systems/

I read that the squad team plans to add new planetary systems beyond Kerbal system, but does anyone know if such systems will be near or far? I would support that would be far, far away, such as the solar system to Alpha Centauri "but then we never would arrive to others systems," you will say. I have the solution and it could be quite desirable. In the interstellar travel have to use technology that in reality do not exist today (nuclear propulsion, antimatter, proton decay catalyzed by monopoles, black holes, negative energy ¿?, etc), and would have add a light speed limit in the game, also add parts to protect the starship of the impact of relativistic particles. Obviously these parts would be large, very large, the hangar not have enough space, and then a new facility should be add "build interstellar starships in space, in orbit". I will expand and adding things gradually in this topic, as I would like to know your opinions to see if this is on track.

Thank you for informing me about the mods , I see that Orion is outdated. Does anyone know if it is compatible with 1.0.5?

I don't mean to nuclear weapon militar use, I mean to this: https://en.wikipedia.org/wiki/Nuclear_pulse_propulsion

Hi! I have been much idle time, but I'm back and I'm back with a new idea: more nuclear propulsion. Justification of more nuclear propulsion: In Kerbal no evidence of the existence of a cold war, nuclear testing and non nuclear proliferation treaty; and also the only life there are those green people living in the rocket base, so no problem with nuclear contamination. (forever alone) The atomic propulsion that I suggest: - Nuclear thermic engine (update): Now make use of only hydrogen (more down) instead fuel and oxidizer. - Radioisotope engine: A little engine similar to ionic engine, little more heavy, that make use of hydrogen (instead xenon) and not requires electricity. - Atomic bulb: A big powerful engine that make use of hydrogen and little of uranium (more down), and produces electricity. - Nuclear liquid uranium engine: A medium powerful engine that make use of hydrogen and uranium. - Nuclear gas uranium engine: A big very powerful engine that make use of hydrogen and lots of uranium. - Uranium bubble: A medium very powerful engine that make use of only uranium (need a new animation to represent ioniced uranium bubble), and lots of electricity. - Nuclear pulse engine: A very big and very powerful engine that make use of 0,8 to 25 kilotons range nuclear detonations to propelling (need a new animation to represent engine move and nuclear explosions), make use of nuclear nukes (there is of different types, mass and power). - Advanced nuclear pulse engine: A extremely big and powerful engine that make use of 25 kilotons to megaton range nuclear detonations. - Polywell nuclear thermic engine: A little-medium engine that make use of a controlled fusion reactor to heat up hydrogen (make use of only hydrogen), and produces much electricity. - Antimatter injection thermic engine: A little-medium engine that make use of very low amounts of antimatter to heat up hydrogen (make use of hydrogen and antimatter), and produces much electricity. Fuels and materials to propulsion: - Liquid hydrogen: in containers of similar size to "fuel-oxidant" containers (any size). - Uranium: in little and shorts containers. - Antimatter: in little and shorts heavy containers, with reinforced texture, these containers consumes a lots of electricity to contain the antimatter, if there is no electricity, it will explode. - Nukes (very expensive, care): of various types, in very width and shorts containers: - 0,8 kt (60 units) - 2 kt (30 units) - 5 kt (20 units) - 10kt (10 units) - 25 kt (5 units) - 50 kt (3 units) - 100 kt (1 unit) of various types, in very width and large containers: - 25 kt (30 units) - 50 kt (20 units) - 100 kt (10 units) - 250 kt (5 units) - 500 kt (3 units) - Megaton (1 unit) Utilities: - Big radioisotope battery. - Nuclear isomer battery: like classic radioisotope battery, but with more intensity, less duration and rechargeable. - Nuclear power reactor (produces a lots of energy, consumes uranium). - Polywell power reactor (produces more energy than fission nuclear, consumes hydrogen and requires big quantity of energy to start). Technology tree: After nuclear node (thermal nuclear engine): - Add: little and medium hydrogen containers/tanks After nuclear node (thermal nuclear engine): - Advanced nuclear node: nuclear power reactor, big radioisotope battery, radioisotope engine, little uranium container/tank, big hydrogen containers/tanks. After advanced nuclear node: - More advanced nuclear node: atomic bulb, gas nuclear thermal engine, liquid nuclear thermal engine, medium uranium container/tank. - Basic nuclear fusion: polywell power reactor, isomer battery. After more advanced nuclear node: - Kiloton: nuclear pulse engine, little nukes containers, uranium bubble. After basic nuclear fusion node: - Advanced nuclear fusion: polywell engine. - Antimatter: antimatter containers, antimatter injection engine. After kiloton node: - Megaton: advanced nuclear pulse engine, big nukes containers.

The airship technology has been proposed many times as a phase in many projects of rockets. Why not in KSP?

Hello, today taking a look at the wikipedia (yes, I get bored a lot, I know), I observed the tripropellant propulsion concept. It not would the tripropellant rocket? Of course italic voice, this concept is called tripropellant rocket. A tripropellant rocket is a rocket or phase that use three chemical compounds to propel, normally these three: - Fluorine, fuel (hydrogen) and lithium. The tripropellant rocket concept is impractical because needing more complexity to support cryonic fluorine and hydrogen (fuel), and the molten lithium (this means more price). Also waste is highly toxic and bad for the environment, but in Kerbal don't have plants or animals, only the green people, so do not worry. (forever alone) This type of rocket would be extremely powerful, as well as the solid rockets, but controllable. So, why not put this in the game (or in a mod)? Incidentally, this type of propulsion would require a new type of engine, more resistent, this also implies the ability to add new types of hybrid engines (Tripropellant or Air-fuel, Tripropellant or Bipropellant, etc).

It is a good idea, would have more traction, I see only one disadvantage: 360 spinning wheels consuming time to change of direction; unlike omni, mecanum and hemispheric that are capable to change direction instantaneously. Anyway, it's a interesting idea and maybe I will add this in the post with other idea that I just found, ball transfer unit.

In the case of omni and mecanum wheels, yes, these only would need action groups to coordinate the wheels, but the controls of each wheel individually would be the same. Oh, and the mecanum wheels would have a diagonal move instead the typical move. For omnidirectional hemispherical gimbaled wheel also, but in this case the wheel would not move as normal wheel, ie, when you press "a" or "d" this wheel would move to sideways easily instead spin to sideways.

Hi, I am new in these forums and I had a idea in mind since time: "omnidirectional wheels". My idea is add these three types of wheel (and variants by company or size, of course): - Omni wheel. - Mecanum wheel. - Hemispheric omnidirectional gimbeled wheel (or simply hemispheric wheel). - Normal wheel capable to spin 360º (thanks to Armchair Rocket Scientist). More detail: >> Omni wheel: This type of wheel is a multi-wheel that contains small wheels aligned 90º over the extreme of multi-wheel. How it works? Small wheels allow that the multi-wheels are capable to crawl without generating friction, is simple and very useful, with this you can make functional omnidirectional vehicles with octagonal, triangular, etc shapes. Robot with this type of wheel in action: <font size="3"> Control: W: move to front. S: move behind. A: spin to left. D: spin to right. Q: spin vehicle clockwise. E: spin vehicle counterclockwise. >> Mecanum wheel: This type of wheel is a multi-wheel that contains small wheels aligned 45º over the extreme of multi-wheel, and aligned 45º over de radius of multi-wheel. How it works? Small wheels deviate the multi-wheels when these multi-wheels spin each in different direction, this causes a lateral or spin movement of vehicle, much more useful. Vehicle with this type of wheel in action: <font size="3"> Control: W: move to front. S: move behind. A: spin to left. D: spin to right. Q: spin vehicle clockwise. E: spin vehicle counterclockwise. F?: move to left. B?: move to right. >> Hemispheric gimbeled omnidirectional wheel: This type of wheel is a half sphere with a vertical axis, this half sphere is connected with a system of rotation. How it works? The half sphere spin in vertical, when is inclined by the mechanism, the direction movement of vehicle changes, the reason is a long geometry and physic explanation. Robot with this type of wheel in action: <font size="3"> Control: W: move to front. S: move behind. A: move to left. D: move to right. Q: spin vehicle clockwise. E: spin vehicle counterclockwise. >> 360 capable to spin wheel (thanks to Armchair Rocket Scientist): This type of wheel is a normal wheel with mechanism capable to spin the wheel. Vehicle with this in action: <font size="3"><font size="4"><font size="3"> Control: W: move to front. S: move behind. A: spin wheel clockwise. D: spin wheel counterclockwise.
