The Marvel comics and movie series Thor is inspired by Norse mythology. What description would make sense for the rainbow-colored Bifrost that appears in this media?

The description of the Bifrost as a bridge used by gods to cross worlds is rooted in its representation in Norse mythology, where it serves as the connection between Midgard (Earth) and Asgard (the realm of the gods). This colorful, shimmering bridge symbolizes the link between different realms and facilitates the movement of gods and other beings. In both the comics and the movie series, this portrayal remains consistent, emphasizing its role as a passageway rather than an object like a weapon, realm, or sword. The vivid imagery associated with the Bifrost highlights its significance as a bridge that embodies the themes of connection and transition between worlds in the narrative.
