Short: No Long Why? (heat) The sun uses its gigantic mass to fuse hydrogen. If the sun was light enough to orbit the Earth it would not generate enough pressure to start the nuclear fusion. Can't it burn normally? No because: You don't have oxygen in/on the sun Burning would only work for a couple of months maybe years. Why (light/energy) When the ...

So, obviously the natural answer is NO. But what everyone really wants is an answer that is YES! Because you have a world where you are not going to let facts get in the way of a good story, right? So now we have to look at ways of making this happen. The situation you describe is the Geocentric Conundrum. How to make things work with an Earth-sized ...

JPL's HORIZONS system will give you ephemerides, charts of a planet's location in the sky (via right ascension and declination) and position in space via quantities like the true anomaly. You can find ephemerides for all eight planets, as well as about 800,000 asteroids, comets and moons (yes, including Pluto and Eris). HORIZONS is quite accurate, and ...

Unfortunately the answer is no. Serious props to you if you want to have a go at coding this. There is probably a PhD in it. One of the primary resources on the topic is the Admiralty Manual of Tides (NP 120). It has been a few years since I worked in the discipline and theory may have progressed but tidal prediction is primarily done by analysing harmonic ...

Keep in mind that what your asking isn't straightforward at all. A true galaxy map must map hundreds of billions of stars and quadrillions (if not more) planets, asteroids, nebula, etc., etc. The Milkyway@Home project is a ginormous effort just to map our own galaxy. Even a map generator that dealt with only 1/100,000th of the data would be mind-...

Simple, this hypothetical site (which of course bears no resemblance to any real site anyone would know) would suffer long term consequences if they don't enforce some kind of quality control. So while in the short run their users would amass more karma, the site would be less attractive to others, so in the long run there would be less users with less ...

My diesel submarine could sail from the port and safely navigate sea with 25% of the crew for a limited period of time, in case of an emergency like a hurricane. (naval ships can ride out some hurricanes in port, but are always safer at sea). The endurance was limited by the ability of the crewmembers to get sleep. The limiting constraint on operating in ...

The answer is 1726. In Jonathan swift's Gulliver's Travels. Laputa is a flying island described in the 1726 book Gulliver's Travels by Jonathan Swift. It is about 4.5 miles in diameter, with an adamantine base, which its inhabitants can maneuver in any direction using magnetic levitation. It has a cave in the very centre which is precisely there to gather ...

The Universe Sandbox has the ability to simulate planetary physics. I doubt that it is 100% accurate, but as a tool for projecting a future it may fill your need. Alternately, the math for working out roughly where a planet is in its orbit is not overly complicated. Find when their next perihelion/aphelion will occur, and simply add the time required to ...

There are places in the world where IQ is low. This table. https://www.worlddata.info/iq-by-country.php ranks countries by average IQ. There are 12 with average IQ less than 70 and 25 countries with average IQ less than 80. Equatorial Guinea is last place with average IQ of 56, which is pretty low and that is the average, meaning lots of people are even ...

You can carve up a galactic disk into colonial empires like Africa, if that is the metaphor you are trying to make. It has been done again and again. But carving a photograph into political boundaries doesn't tell us much about anything, except the relative sizes of the "empires" which we can infer to imply power and resources (although our own maps suggest ...

Hastur is a reflection of what people think he is. If Hastur just needed upvotes, he'd build a website dedicated to cat videos. Even elder gods love cat videos. However, Hastur's need for worship isn't a simple "5000 upvotes for an extra +5 to infernal wailing" equation of upvotes to power. Instead, Hastur build his power off of human perception of what ...

Do you really think a bunch of upvotes is Hastur's master plan? We're talking about an Elder God for Pete's sake! The whole point of invoking these gods in a story is that they are incomprehensible! So my rationale for the rep caps and the closed questions is "w̹̞̤̞͕͍̦͞ḥ̤ỳ̟͉̮̼̲ͅ n̵̟̘̝o͏̛̮͍͙̯͔̣͘͜ṭ̟͓͍͕͚͍͠ͅ?" Now let's talk really perplexing ...

In my answers to this question Day/night cycle science help?1, and this question Could this planet exist?2 I discuss factors which could change the relative length of day and night on a planet.

Crew 134 Regrettably, this is the nuclear version, not the diesel version, but I suspect the crew complement is nearly identical because, diesel-vs-nuclear, you need about the same number of people to keep the engine running. From Submarine 101 Submarines play a central role in my books, so I thought it’d be a great idea to provide an introduction to ...

Climax forest is not the best habitat for wolves, because they're carnivores and it's not the best habitat for their prey. Most prey species, and especially deer and other medium sized solo grazers, prefer "edge habitat", areas where they can access the cover of forest and the good grazing of grasslands. Woodlands on the edge of grasslands with an annual ...

Of course. As with many aspects of writing fantasy, the answer will almost always be "yes, of course! It's your world, you make up the rules!" Like: Can I have dragons? YES. Can I have Elves? YES. Can I have portals? YES. Can I have polydimensional beings that ordinarily consist of dissociated arrays of tentacles bilocate into our universe as large purple ...

Other answers have explained that our sun's simple design would not work if scaled down to the size of the moon. Our sun's design is: pile enough hydrogen and helium together that the pressure at the center is so hot that you fuse hydrogen to make helium. The waste heat from this nuclear reaction eventually gets to the surface, where the surface' plasma ...

Jack and the Beanstalk More than 5,000 years old. There exist many variants, the Wikipedia version of the story is thus: Jack is a young, poor boy living with his widowed mother and a dairy cow, on a farm cottage. The cow's milk was their only source of income. When the cow stops giving milk, Jack's mother tells him to take her to the market to be ...

Telekinetic ability Hold on, let me explain... Keeping our everyday force-field magic, fireball jutsu and wand waiving aside, you might want to take this ability into consideration.

In addition, TSoft offers ...

Yes, it is a very common clichè. To make it into a less common clichè, perhaps, you could have that your world is already hell, but people just don't realize it.
