The actual explosion of a supernova isn't really all that much "entertainment." It's an extremely bright flash. The formation of the nebula might be interesting. But that is a much longer process, starting at months and upwards to 100s of years. And, if you are far enough away as not to be fried by the initial flash, you will need very good ...

Yes, it makes sense for several reasons: trade Even if each settlement and ship are fully self-sufficient trade between them will eventually be established. The only exception is when distances are so huge that trade is absolutely impossible. Please note, trade does not have to involve material goods. It is much easier to develop and protect trade when ...

The Electric Universe people were right. There are plasma filaments connecting all the stars, carrying incredible amounts of electric current. Only between the stars is it possible to tap into that energy, so the areas in the middle of the filaments are hotly contended.

Safe distance estimates vary 50-100 LY 100 LY 25 LY Now, if you add a glassy shield, it would depend upon how effective this shield is. Blocking 75% of radiation means only 1 part in 4 harmful radiation gets past your shield - this would allow you to be twice as close since the radiation falls off proportional to distance squared. If you had a 100% effective ...

It Will ... Eventually Space as of now, 2021, is pretty much a lawless place. We might think of it as the period before the "Wild West" era of American history. Think of the Moon landings as Leif Eriksson landing in Canada. Think of the various probes from Voyager right on up to the most recent Chinese rover on Mars as De Soto and Lewis & ...

Energy generation In the vastness of space there is something. We don't know what it is or how to see it, but we can see it's effects. It pushes whole galaxies apart, while seemingly invisible. This is dark energy. There is a great abundance of it to be so powerful and most is likely in the vast emptiness of space between star systems and galaxies. Stars, ...

Vast voids which are devoid of gravity, particulate and radioactive interference are the perfect place to grow the flawless crystalline structures needed for the post-singularity level artificial intelligences. The computing power of any AI is strongly correlated to the size and purity of the circuitry that it lives in. Every supreme intelligence at the ...

Earth's magnetic field is generated by the spinning of our iron core, not by the spinning of Earth in space. Theoretically, you could have a non-spinning planet with a spinning iron core, which would still have a strong magnetic field. On the opposite side, Mars is a planet which spins almost as fast as Earth, but without that spinning core, its magnetic ...

There are three main traits that make these places different warfare-wise: the horizon, the air(or lack thereof), and gravity. The horizon: on a flat area of Europa you'll get a horizon at around 2 km, depending on how tall you are. This effects all modes of spotting and detection including radar. (Most of these don't have a magnetosphere to bounce radar ...

Mothership (full of fuel and supplies close to the transport’s destination) to space vehicle EU W2775LV be like "pay taxes!" Space vehicle EU W2775LV (near its destination, needing to slow down (not speed up) to enter orbit, almost out of fuel for maneuvers, and running low on other resources) : yes, please There’s a narrow range of velocities to ...

a space chase never ends That's not entirely correct, a ship presumably goes from somewhere to somewhere else. If it doesn't, then it truly doesn't matter what they do, they're effectively their own sovereign nation outside of anybody's effective control. It's when a ship shows up to a spaceport with a dead body, a cargohold full of drugs, or outstanding ...

We have an analogous situation with the internet. Which is to say, it is possible to anonymize and encrypt your traffic with several hops through VPNs to make you unreachable physically by people you are communicating with, creating pockets of ungovernable space. We see ransomware attacks on the news with official government responses along the lines of &...

If airtightness is the only requirement, then yes, medieval people could create such vessels By middle ages, creating watertight ship hulls was a very common task. Yes, ships leaked, but that could be successfully mitigated. Also, diving bells were known since antiquity, and fully isolated "dry" bell is not very different from a spaceship. 1 atm ...

Install a powerful refrigerator in the projectile. Cold refrigerant coils cover the forward surface. The heat from molecular collisions is pumped from the front to the back, where it is radiated away. If the heat generation rate from collisions matches the rate at which heat is radiated away, the projectile won't reach excessive temperatures. The ...

By far the best natural resource is to be found in empty space is emptiness. The French tested nukes in the Algerian desert. Americans decided to nuke their own desert. Apparently deserts are fun to nukes. Well empty space is the desert of the universe. You can test all sorts of weapons, maneuvers, and other schemes far from prying eyes, and far from ...

Government makes sense only to the extent that control can be maintained. If your propulsion is such that only single-body colonies can be controlled that will be the extent of your government. If instead somehow your propulsion is extended such that entire solar systems can be reached in reasonable times then government will extend to fill that niche. And ...

No. they can't make a airtight container big enough for weeks of travel, especially not one that can withstand vacuum. Even a day of travel is probably impossible. You need a shipping container worth of air per person per day. Since it needs to have doors it gets even less likely they can make it airtight. The only technology they had for making airtight ...

The particles you will be impacting are of two types: charged and neutral. Providing the bullet with a magnetic field will deflect the charged particles and leave you only to impact the neutral particles. This will result in a lower fingerprint and a more difficult detection.

For a government to exist, it needs to have power over people, or to provide them with useful services (or both). If the people on the spaceship can't be caught, they might still want to make use of government services, for the education of their children, or healthcare, or providing a safe place to trade / take holidays / hire crew. In order to enjoy these ...

Matter generation What we think of as empty space is full with activity. Thanks to fluctuations of the quantum field virtual photons pop in and out of existence, one positive and one negative, which cancel each other out. With light these can be turned into real photons, which means you can create something out of basically nothing. Uf you push this real ...

The answer by thewildnobody gives the best explanation of what would be different. I thought I would try and take those points and synthesise them into a conclusion as to what a war would actually be like: It would be a cold war (Pun intended) The most similar "war" fought in history is the cold war: There would be no direct action involving large ...

Sure a space government can make sense IF they control the means of production for creating critical systems and materials. Sure space vehicle EU W2775LV can take off and avoid taxation, until it needs fuel that is. It was carefully built to be dependent on outside manufacturing for that, so was the mothership for that matter. They also don't have the gear, ...

None. SETIs latest estimate puts total scrambling of non-targeted radio and television signals at slight less than 1 light year. It's not that the energy of the signals doesn't keep travelling but beyond 1, maybe 2, light years the amount of interference makes the signals undetectable as anything but a tiny bit of extra noise. However They do estimate that ...

First of all, let's refresh what a solar flare is https://en.wikipedia.org/wiki/Solar_flare It EM flash with or without coronal ejection. Without there is nothing special about it, more or less. With mass ejected it a bit more interesting. But the point is it not an emp blast next to a robot, so EM part does nothing. And particles they are not gammarays and ...

Hiding valuable assets In a sufficiently populated galaxy, there could be countless potential threats and attackers in all directions, too many to keep track of or anticipate. Space is just too big. So instead of expensive force fields and hyper-sensitive early warning systems, every civilization will locate important installations in large regions of empty ...

Computation is more efficiant at lower temperatures https://en.wikipedia.org/wiki/Landauer%27s_principle So lets just say you are running tons of simulations you might want to get as far away from a heat source you can

I assume that the problem you want to solve is that the cybernetic brain could somehow be corrupted or deleted entirely. (Whether or not that's plausible doesn't matter because this is your world). One option could be automatic backups to a storage medium which is immune to solar flares. When the cyborg gets knocked out by a solar flare, their mind gets ...

What is a solar flare? A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar system’s largest explosive events. They are seen as bright areas on the sun and they can last from minutes to hours. We typically see a solar flare by the photons (or light) it releases, at most ...

Sure (eventually) Mars runs itself and Venus runs itself, but what happens when Mars wants to trade with Venus? Sure ships can start moving goods between the planets but someone will come along complaining that those Venusian's are under cutting the local Mars built products. Thus people will demand that something should be done about it. The usual way then ...

Consequently, each State handles its issues with the laws that pertain to its jurisdiction, except monetary issues, such as the printing of money. Other examples of decentralized governments include the governments of Australia, Canada, Germany, and India. As no one recalled about decentralized government examples, seems it needs a reminder. In some sense ...
