The idea of a 'multiverse' - multiple universes existing alongside each other - is something science fiction and fantasy fans are fairly au fait with. Parallel realities in which you made a different decision at a pivotal moment and, as a consequence, have evolved in entirely different ways, have been fodder for authors, scriptwriters and 'what if' musings for some time, but recently, scientists - specifically cosmologists - have been taking increasingly seriously.

For more cosmology, try [[Einstein's Telescope: The Hunt for Dark Matter and Dark Energy in the Universe by Evalyn Gates]], and [[Quantum Theory Cannot Hurt You by Marcus Chown]] is a good place to start when trying to understand the trickier theories involved.
