Hello, SFIA audio listeners. In this month's Nebula exclusive, big alien theory,

we're asking the reason alien civilizations might be rare is because most aliens are huge.

If hyperspace were real, what dangers might lurk in the great unseen, and could it ever be more than a sci-fi dream?

From warm holes to warp drives to hyperspace lanes, science fiction has given us imaginative ways to cheat the cosmos, but is in even possible?

And what is hyperspace anyway? Grab a drink, a snack, give the like and subscribe buttons a smack, and let's explore hyperspace.

Hyperspace is an intriguing concept that bridges the gap between science and imagination,

often serving as a stand-in for Fast and Light FTR travel in speculative stories.

Its presentation varies widely, appearing in major science fiction franchises like Star Wars,

Isaac Asmos Foundation series, and TV shows such as Babylon 5. At its core, hyperspace refers to an alternate dimension or

higher dimensional space that allows travelers to bypass the normal constraints of our universe. Instead of being restrained by the cosmic

speed limit, the speed of light, hyperspace offers a theoretical shortcut, enabling rapid

journeys between distant points in the cosmos. While the term hyperspace doesn't have a direct

and universal counterpart in current scientific models, it draws inspiration

from real physics concepts, such as higher dimensions in string theory, wormholes, or the

manipulation of space-time. Its interpretation in science fiction reflects as much narrative

creativity as scientific plausibility. In science fiction, hyperspace has not just a tool for traveling faster than light, it's

a rich narrative device that shapes the words and stories built around it.

In Star Wars, hyperspace lanes offer established routes for interstellar travel, bottlenecks

for trade, piracy, and battle.

In Dune, the Spacing Guild's forward space ability allows instantaneous movement through
