Alternate universes refer to the concept of multiple, parallel realities that exist alongside our own. Each universe can have different histories, outcomes, or physical laws, resulting in worlds that are similar or vastly different from what we know. This idea is popular in science fiction and theoretical physics, allowing exploration of "what if" scenarios, such as alternate versions of events, people, or even entire civilizations, expanding the boundaries of imagination and scientific inquiry.

What are alternate universes?
Alternate universes are parallel realities that exist alongside our own, each with its own history, outcomes, or physical laws.
How are alternate universes different from alternate timelines within the same universe?
Alternate timelines are different histories within a single universe; alternate universes are separate realities that may not interact and can have different physical rules.
Could alternate universes have different laws of physics?
Yes. In some theories, universes may have different physical constants or laws, leading to very different kinds of worlds.
Is there scientific support for alternate universes?
Some physics theories, like the multiverse or many-worlds interpretations, propose their existence, but the idea remains speculative and unproven.
