In a parallel universe if two objects occupy different positions in space then in the reference frame of each object the other has length contraction and time dilation. If the two objects are very...
A civilization wishes to create a wormhole connecting its universe to a universe with a different spacetime metric. For instance if we describe a timelike dimension with $+$ symbol and a spacelike...
I was thinking about how there are some instances of convergent evolution between marsupials and placental mammals and was thinking about a parallel universe in which there is convergent evolution ...
All known life forms have life cycles that are not time symmetric as they look different when time is reversed. I was wondering if there could be a life form that would have a life cycle that wou...
With technology it is possible to detect Gravitational waves as Gravitational waves have been detected by LIGO. Could a species evolve to have a sense organ for detecting Gravitational waves? Wha...
I was thinking of a situation in which a creature lives in a region in which the levels of radioactivity varies from harmless to lethal from place to place and time to time. It takes millions of y...
I was thinking of a situation in which a life form evolves a biological screen somewhere on its body that can play videos. The life form would play videos on its biological video screen in order t...
Because Boron is directly to the left of Carbon and Nitrogen is directly to the right of Carbon on the Periodic Table Boron-Nitride has the same types of bonds and so as carbon and so in combinatio...
I understand that the human brain consists of many cells working together but could a single celled life form evolve something like a brain with similar intelligence to the human brain? I was thin...
I know in fiction Sonic The Hedgehog is able to run faster than the speed of sound but could an organism actually evolve to move faster than the speed of sound? What type of fuel would such an org...
In a parallel universe, death is physically impossible so nothing can ever die but this universe has lots of life. It is also physically impossible for any life form in this hypothetical universe t...
I was thinking of a scenario in which a population of snakes gets stranded on an island in which they are literally the only animals. This hypothetical island does not even have insects for the sn...
Would it be possible to produce a pair of human brains that are connected by a wormhole that has each end inside one of the brains? What I had in mind is that the wormhole would have neurons insid...
There is a place that has a natural boundary that allows all animals and plants to enter that place but any animal that can't fly is unable to leave that place. This place is large enough to have ...
In a parallel universe the uncertainty in position and the uncertainty in momentum are directly related to each other. What kinds of effects would this have on the quantum mechanics of this univer...
I was thinking of an organism that has evolved to get its energy through nuclear fusion. It has its own fusion rector inside its body that is capable of fusing hydrogen to helium to derive energy....
In a parallel universe much of the physics equation have tetration in them. There are things such as tetrational growth as well as tetrational decay. $x^x$ and $x^{x^x}$ are also found in some ph...
In our universe if there are two objects that are moving relative to each other then each will see the other's length contracted in the direction of motion and it will see the others clocks running...
I know that in our universe, electromagnetism and gravity decrease with the inverse of the distance squared. Would it be possible though for there to be a force in another universe with three spati...
I was thinking of a hypothetical universe in which electromagnetic waves decrease in intensity with the distance instead of the square of the distance. What kinds of effects would that have on that...
I was thinking of a scenario in which people decide to use breeding to try to make two species more genetically related to each other. The people take genetic samples of each individual from their...
In an alternate universe there is a force known as the emotion force although the force has nothing to do with emotions. Anything that interacts through the emotion force has an emotion charge tha...
Gauss's Law states that the electric field enclosed by a sphere, or any other surface is the same as the charge divided by the electric constant. What if in another universe Gauss's law was, "The ...
An alien life form is found that has a pattern of stripes on its back. The pattern is black, red, yellow, green, cyan, blue, and magenta, black, and so on. It is found that for each series of dif...
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...
