The most common denominator in isekai (parallel worlds) and time travel scifi is: “each reality is vibrating in a unique frequency”.

It has been around since the 90s, from Japanese anime to Western live-action TV series.

How did it start? Who first used it? I have no idea. Maybe it started from DC or Marvel comics, or even earlier than that.

Nonetheless, it was the simplest idea (I think) to answer the question: “How can we detect if someone is from a different world/reality?”

And it actually works.

And maybe, just maybe, if alternate realities do exist, we do vibrate in different frequencies.

These are some of the fictional works that I remember (or I'm misremembering) which used this ‘theory’.

* Dual! Parallel World Trouble / Tenchi Muyo universe
* Serial Experiments Lain
* Star Trek
* Sliders
* Fringe
* The Flash

What else? Do you remember any?
