11. Chemical Issues Must Be Minute
One of the things a planet needs to work for humans may not technically be a certain “thing” but rather, something that won’t be present. We’re thinking something like chemical problems here. For example, if we decide to bring out a gas-powered vehicle to travel around the planet in, will it randomly blow up once started?
Are the same laws of physics and chemical properties in play here mostly as they are on Earth? We know how things operate from a scientific standpoint here. Yet on other planets, the same things may be far different. If the moment we land, everything becomes impossible to understand or takes a long time, it could cause issues with colonizing.
