I think a reasonable assumption is that you don't want to accumulate entropy from the Dyson sphere. That is, the entropy you get from the star must not be lower than the entropy you send to outer s...
Both the other answers (at this time) suggests making the orbit eccentric. The variable distance from the sun makes the planet hot or cold. This is correct. But there is one important aspect of ...
As L.Dutch said, lightning is super energetic and any plant probably wouldn't survive it's strike. What I can imagine is the forest benefiting from some of its trees taking the hit for the team and...
Depends on the orbit I'm drawing on my answer to a different question here. Let's start with an overview of why there are seasons. I really like this description: We have seasons because the e...
Yes, it can. We can determine the distance to the source if we have an idea of what's causing that shift in velocity. Let's say that we have a source moving at a speed $v$ away from us. If it emit...
It would depend on the eccentricity of the orbit and the size of the orbit. So there are a number of orbital possibilities to consider. The problem even more complex because of a number of other va...
Not gonna lie here, that looks way more like an disadvantage than an advantage. The main problem here is that this seems like an unnecessary redundancy. Yes, morays have 2 sets of Jaws, but the se...
Your star is not going to work, so the planet won't either. Mass of star: 1.04 M☉ Radius of star: 0.69 R☉ Surface temperature of star: 4,620° K Luminosity of star: 0.2 L☉ ...
Leaving aside the durability issue, you should probably be looking at electronic paper. They work by moving colored particles back and forth to create the image. The term you're looking for is call...
No. The way we define latitude and longitude is based on the planet's axis of rotation. You can certainly (AFAIK) have a planet with a 90° axial inclination, or (probably) a planet that is identica...
For an in-situ born planet, it can happen, though it is hard to have the exact chain of events. Basically you need to have a series of gravitational slingshots with a larger body that put your pla...
I think that this topic is one that's likely to generate a lot of misconceptions when people answer it, since it's a complicated topic and analogies/explanations that are given by pop science are o...
Let me see if I got this right. You want to conjure an object, have it contain enough mass and gravity to collapse on itself without dissipating, motivate it to move at FTL speed, drag your vesse...
Interpretation: ET's blood equivalent is primarily composed of caramel, with some additional components, but without hemoglobin. The flesh tastes terrible, without rendering the caramel blood ined...
I'd imagine that they'd build double skinned shield walls to deflect the noise from waterfalls. The most expensive parts of the city would also be the quietest, while the slums would be where the s...
100% YES It s called an updraft tower. You can actually even do that on earth in the Deserts (solar updraft towers). https://en.wikipedia.org/wiki/Solar_updraft_tower On Venus you wouldn't even...
TL;DR: the mechanical issues of a biological gun would be very, very difficult to overcome. If they were overcome, the energetic costs of firing sufficiently large projectiles at sufficient speeds ...
What L.Dutch said, plus whatever process is making the hull rotate is making it act like a turbine from a wind or hydro power plant. From a certain point of view, the whole outside of the ship is a...
Stabilization by gyroscopic effect, plain and simple. A gyroscope (from Ancient Greek γῦρος gûros, "circle" and σκοπέω skopéō, "to look") is a device used for measuring or maintaining orientati...
Be Flexible With What Counts as Wings Your griffons are four legged as the common depictions show, but rather than wings separate from the limbs instead there is a gliding membrane like that of a ...
Reduced Jaw Muscle The brain of primates is slightly smaller than the brain of a human, which is thought to be the main reason for the intelligence gap between the species. The reasons why a monke...
Paranoid Schizophrenia. The brain is malfunctioning, it perhaps contains a brilliant intelligence or valuable information, but the dopamine receptors respond abnormally. The artificial brain to w...
It is an interface issue. Your technology has one step that converts the brain to computer data Reading out the personality and memories of a person from their brain requires that the brain is...
It turns out there's something very much like this, right next door to Earth. Observe the topography of Mars: (Image courtesy Wikipedia; larger version here.) The large blue areas in the northe...
