Why space games still struggle with the scale of the universe

So huge that the human mind struggles to even conceptualize it. The observable universe spans roughly 93 billion light-years. Even our own humble galaxy, the Milky Way — a few tiny stitches of the universal canvas — stretches across 100,000 light-years and contains hundreds of billions of stars.It’s no wonder, then, that space video games struggle so mightily with anything approaching a “realistic” interpretation of those incredible distances, especially in an age where we have yet to invent a technology that can traverse them in a reasonable time.AdvertisementAdvertisementThe Artemis 2 mission’s Orion module got up to speeds of around 25,000 mph during its trans lunar injection burn. Ignoring fuel and safety concerns, at those speeds, it would still take us at least 80,000 years to reach our nearest neighbor, Alpha Centauri.So how do game developers manage to distill some of the awe of the vastness of space while making it feel like a manageable space? How do they shrink space to a navigable size without making it feel small or claustrophobic?I spoke to astrophysicist Dr. Jeffrey Bennett, founder of Big Kid Science and author of “The Scale of the Universe”, to get a sense of the scope of the problem.The true scale of spaceCredit: wasan prunglampoo/Getty Images”On a 1 to 10 billion scale — which makes the Sun about the size of a large grapefruit — Earth is smaller than the ball point in a pen and located about 15 meters (49 feet) away from the Sun,” explains Bennett. “On that same scale, the Moon — the farthest a human being has ever traveled — lies only about 4 centimeters (1½ inches) away from us. The planets of our solar system are much farther, though you can still walk to the outermost planets in only 10 minutes or so.”AdvertisementAdvertisementBennett said most science fiction films and games get the scale wrong by making long-distance travel look too easy. Considering the above 1-to-10 billion-scale representation, for instance, and given that reaching the outermost planets in our system — far further than any human being has ever travelled — would take ten …
