Why Space Video Games Can’t Accurately Depict the Vast Scale of the Universe
Space games struggle to portray cosmic distances, from the 93‑billion‑light‑year universe to a 25,000 mph Orion speed, forcing developers to shrink reality.

Space is so vast that even the most ambitious video games stumble when trying to capture its true magnitude. The observable universe stretches about 93 billion light‑years, while our Milky Way spans roughly 100,000 light‑years. Recent interviews with astrophysicist Dr. Jeffrey Bennett reveal just how tiny planetary distances become on a 1‑to‑10 billion scale. Understanding these limits matters for both game design and public perception of astronomy.
What happened
The article notes that the observable universe is about 93 billion light‑years across, dwarfing the 100,000‑light‑year Milky Way. This sheer size makes any attempt to model true interstellar distances in real time impossible with today’s processors.
Even the fastest human‑made spacecraft, such as Orion’s 25,000 mph trans‑lunar injection, would need roughly 80,000 years to reach Alpha Centauri, illustrating how current propulsion concepts cannot bridge cosmic gaps within a game’s playable timeframe.
Bennett’s 1‑to‑10 billion scale shrinks the Sun to a grapefruit, places Earth a ball‑point size 15 m away, and puts the Moon only 4 cm distant. On that scale, walking to the outer planets would take about ten minutes, while reaching the nearest star would require a trek across the United States.
Why it matters
The mismatch between perceived and actual distances can shape player expectations about space travel, potentially reinforcing misconceptions. Developers must balance scientific fidelity with gameplay pacing, and hardware constraints often force simplifications that affect immersion. Accurate scale also offers educational opportunities, turning games into informal outreach tools.
- Creates dramatic, fast‑paced gameplay that keeps players engaged.
- Allows developers to work within current hardware limits.
- Enables artistic freedom to craft memorable worlds.
- Can embed false ideas about how far stars really are.
- May strain processing power if realism is pursued.
- Often forces unrealistic travel speeds, breaking immersion for informed players.
How to think about it
- Define the narrative distance needed. 2) Choose a consistent scale factor. 3) Use visual cues such as star density and travel‑time indicators to hint at vastness. 4) Offer optional “real‑scale” modes for education. 5) Test performance on target hardware to ensure smooth gameplay.
