For questions about environments with extremely low perceived gravity (colloquially referred to as "zero gravity", usually referring to a free-fall environment in space) and the impact of such environments on creatures and technology.

This tag relevant to situations where there is little to no gravity. For questions where gravity levels are variable (i.e. 'how much gravity would this planet have', or 'how much gravity would I need to do X') the [gravity] tag is appropriate.
