According to our current understanding of physics, light from beyond the observable universe cannot reach us by traveling through a wormhole. The observable universe is the portion of the universe that we can currently see or detect because light from those regions has had enough time to reach us since the Big Bang.
A wormhole is a hypothetical tunnel or shortcut in spacetime that connects two distant points. It is a concept derived from general relativity, Einstein's theory of gravity. While wormholes are mathematically allowed within the framework of general relativity, they are purely speculative at this point, and there is no experimental evidence to support their existence.
If a wormhole were to exist, it could potentially provide a shortcut through spacetime, allowing for faster-than-light travel or communication between two points. However, there are significant theoretical challenges associated with traversable wormholes, such as the need for exotic matter with negative energy densities to stabilize and keep the wormhole open.
Even if a wormhole were somehow stable and traversable, it would not enable us to observe light from regions beyond our observable universe. The observable universe is limited by the distance that light has had time to travel since the Big Bang, which is about 93 billion light-years in radius. Light from regions beyond this distance, even if it could somehow pass through a wormhole, would still be beyond our reach because the light itself hasn't had enough time to reach us.
It's important to note that our understanding of the universe and its fundamental properties is continually evolving. While wormholes remain a topic of theoretical research, there is currently no scientific evidence to suggest that they exist or can be used to bring light from beyond the observable universe to us.
