I imagine multiverses existing separately from each other, the way solar systems exists separately (I mean, shoot, why not?), but according to a video I watched, their theory is that the multiverses all exist in the same spot in a different dimension... He compared it to all radio stations existing together with radios only picking up one station at a time, and that we're just picking up this one universe..

Yours is the current thinking.
If you only have time to look up one of the sources cited, watch the 20 minute talk by Brian Greene at TED. Listed below.
Spacetime is not nothing. It has properties, it can be bent, warped, twisted. Spacetime has structure. Spacetime is pervaded by Dark Energy. In fact, Dark Energy may be the structure of Spacetime, what we call the "Fabric of Spacetime
So, we have a huge amount of energy stored in the Fabric of Spacetime. A quantum fluctuation releases some of that energy as a Big Bang creating a universe. It is all a matter of scale This process has gone on in the past and continues today creating an infinite number of universes. We see the Big Bang not as a unique event, but as a regular event that fits with a logical, consistent physical process. Physics makes the most sense without unique events. A physics that allows unique events is unpredictable and borders on magic.

A current idea being worked on by some cosmologists is that our universe exists within a multiverse of many other universes -- perhaps an infinite number of them. Each universe would begin with its own Big Bang. The time-space of each universe is separate from all the others.

Science is anything that can be measured. What you are talking about is science fiction, which can be anything you want.
