Warning: contains spoilers for Spider-Gwen: Gwenverse #2!
Marvel continues to push the Multiverse in a major way in both movies and comics — but even they appear to be tired of the concept. The ability to bring multiple versions of the same character from different universes together makes for a variety of interesting story concepts, and is admittedly an excellent vehicle for superhero team-ups. But the concept may have hit a creative wall, as Spider-Gwen: Gwenverse #2 contains an exchange between two living versions of Gwen Stacy that most fans will find quite familiar when discussing the stakes (0r lack thereof) in multiverse-based stories.
The concept of a «multiverse» is not new, nor limited to comics. The term was first used in 1952 during a lecture by Erwin Shrödinger, in which he explained that the principle of quantum superposition allowed the possibility of multiple simultaneous histories to occur at the same time, essentially describing the multiverse in all but name. The DC readership is quite familiar with the Multiverse concept ever since the company revealed that Jay Garrick and Barry Allen — two versions of the Flash — existed simultaneously in different dimensions in Flash of Two Worlds; 1986's Crisis on Infinite Earths expanded upon that one issue to tell a story about the infinite multiverse. Marvel's multiverse exists as well, but their stories usually involve variants in different realities entirely (see the What If...? line of comics and accompanying Disney+ series).
