The Doctor's TARDIS is larger on the inside than on the outside. How can this be achieved? The conventional answer is that The TARDIS is dimensionally transcendental ... the interior exists i...

Imagine a cuboid planet with a thick atmosphere orbiting a star similar to our Sun. The inhabitants are as intelligent as humans and recently discovered the universal laws of gravitation and motion...

In this question, I asked about a universe with (amongst other things) 4 large spatial dimensions. In 3 dimensions, we have the familiar periodic table with its familiar arrangement of atoms in th...

Summary The main idea behind the "cuboverse" is that spacetime distances are measured by (something close to) the sup norm or infinity norm. Under this norm, spheres (the set of points at a fixed ...

Suppose you have a 2+1 dimensional universe where the physics of that universe (we'll assume that the physics causes something similar to chemistry and that there is no gravity, but there is specia...

I know that someone has asked how chemistry would be in four dimensions but I was wondering what would chemistry be like in two dimensions? From what I understand, in two dimensions, particles, ins...

I have an idea for a world such that the world itself is like a large loop. The best way I can think to describe it is going step by step through the "loop". Imagine a planet-like object; a sphere...

Let's say our world is set in a hyperbolic space with a curvature K of −1 per 9 square meters. How would crystals be different than those in our world (assuming that the atoms are the same as the ...

The Parachute Cities fall endlessly, ploughing their way downwards through an infinite blue sky. The Big Blue is a universe of sorts. It certainly has no bottom, but it does have a concept of "˜do...

So, I the question of what if a black hole hits the earth has been asked to death by various people, but what if the somewhat tamer wormhole hits the Earth? In particular, we'll say that one mouth...

This question has some close votes but has been edited/clarified, and has attracted more comments and discussion over the possible answers, and the geometry has overshadowed the actual question bei...

I'm inspired by this question and was thinking that it is nigh impossible for sun, moon and star to exist in this world and even if they do, there is no way to sun and moon to orbit and create day-...

After playing some HyperRogue, I got interested in the use of hyperbolic geometry in WorldBuilding, in particular how an area grows exponentially with respect to its radius. Let's say that the uni...

In this question, I asked about a matter-filled 4-spatial-dimensional universe, with a gross structure defined by my own answer to that question. Then, in this question, I asked about what the per...

I was reading Flatland, and the thought occurred to me that interaction between an n-dimensional being and a n+1+-dimensional being may not only be difficult but dangerous, that Flatland contains e...

This is a follow up to What would physics be like in a wrap-around universe? PyRulez commented, "Will gravity still make sense? (Namely, will it converge or not)?" This was bantered about in the c...

Assuming humans live in dimension 3+1; 3 spatial dimensions, length width and height, and one dimension of time, Is it possible to move matter from our dimension 3+1 to another, such as 4+1 (addin...

Assuming that we have a universe with four spatial dimensions plus time, within which atoms exist that can form solids, liquids, gases and plasmas, the compounds that can be formed having physical ...

In my answer to my own question, Physical laws for a matter-filled universe, I detail the gross physical laws that would shape my four-spatial-dimensional matter filled universe. Given a slowly ex...

Imagine your scientists have found a way to increase the space of your empire, literally: They are able to create an artificial inflaton field which locally creates a "space bubble" connected with ...
