Anywhere door in real life?

The Dokodemo door, often known as the “anywhere door,” is a famous fictional trope that allows for instantaneous travel. The name is derived from the Japanese word dokodemo, which means “everywhere.”

The idea is simple: a door that can go to any location, no matter how far away it is. It has appeared in several works of fiction, ranging from Alice in Wonderland to Harry Potter and the Philosopher’s Stone. Is it, however, possible to create an anywhere door in real life?

Unfortunately, it looks that the answer is no. The laws of physics prohibit such a thing from existing. For starters, there’s the issue of momentum conservation. This basic law would have to be broken for an item (or person) to travel from one location to another in an instant.

There are other issues as well. Even if we could overcome the momentum issue, there’s still the question of where the door would go. What’s to stop you from travelling from New York to London, for example, from ending yourself within a solid wall? Worse still, what if you ended up in space?

So, for the time being, it appears like any doors are nothing more than a fantasy. But who knows? Maybe someone will figure out how to make them work someday. Until then, we’ll have to make do with good old-fashioned doors!

Can we make an anywhere door in real life?

The concept of a “anywhere door,” which allows instantaneous travel between two locales, appears frequently in fiction. Is it, however, possible to build such a door in real life?

There are various approaches to creating anything like an anywhere door. One option is to use a wormhole. A wormhole is a hypothetical topological structure that would fundamentally connect two places in space-time. It would essentially be a shortcut through the universe. While theoretical physics has extensively investigated wormholes, there is no observational evidence for their existence.

Another option is to employ an Alcubierre drive, sometimes known as a “warp drive.” This is a hypothetical method of faster-than-light travel in which space behind an object expands while space in front of it contracts, resulting in effective movement faster than the speed of light without violating any physical laws. However, this technology has yet to be created, and scientists are still debating its feasibility.

So, while an anyplace door isn’t currently possible, there are surely methods we may make it happen in the future!
