Venturing Into Parallel Worlds Day
Venturing Into Parallel Worlds Day is held on April 26. This event in the third decade of the month April is annual.
The concept of multiple universes, or a multiverse, has been discussed throughout history, with origins in ancient Greek philosophy.
The multiverse is the hypothetical set of all universes. Together, these universes are presumed to comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called "parallel universes", "other universes", "alternate universes", or "many worlds". One common assumption is that the multiverse is a "patchwork quilt of separate universes all bound by the same laws of physics."
Some scientists and philosophers believe that parallel worlds are real and that there are ways to cross between them. A day of forays into parallel worlds is a day for creativity, adventure, and discovery.
