If an item has mass, then its mass is constant regardless of where it goes ...
whether it's on Earth, in the air, on the moon, or in space on its way from one
place to another.
Your mass would still be 158 pounds in outer space. Mass is a measure of the amount of matter in an object and does not depend on gravity. Your weight, on the other hand, would be different in outer space because weight is the force of gravity acting on an object's mass.
Zero is not correct. Your weight may be zero in parts of space, but not in others. Weight, however, is a different thing altogether to mass and it is important not to confuse the two. Mass is the amount of matter in an object and this remains the same.
If the space is in outer space there can be no gas against which a terminal velocity can occur
Absolutely not! Any body has the same mass anywhere. The weight of a body is the effect of gravity on the mass.
the amount of matter in a given space; mass per unit volume
Mass can be measured in outer space using tools such as balances or scales that are specifically designed to work in microgravity environments. These instruments rely on principles such as inertia or the effect of gravitational forces to determine the mass of an object.
outer (as in "outer space")
Its weight depends on the force of gravity acting on the mass. In outer space, for example, its weight will be 0.
A body always has mass. The Weight is dependent on the gravity inflicted on that body. According to F=mg, where Weight is equal to "F", Weight is 0 when gravity is equal to 0. The only place that gravity is 0 is in outer space so there's no weight in outer space but you will always still have a mass.
There is no antonym for outer space.
