That really depends on the nature of the space plane and the technology used.
The shuttle (a space plane) reduced the cost of space flight dramatically and made the payloads larger. But it was mainly due to the reusability and size of the shuttle.
When a can is crushed, the volume decreases due to the change in shape. The material inside the can gets compacted, reducing the amount of space it occupies. The actual change in volume depends on the extent of the crushing.
No, the Earth is not getting bigger from dirt. While sedimentation and volcanic activity can add material to the Earth's surface, the overall mass of the planet remains constant. The Earth accumulates material from various processes, but it does not result in a net increase in size.
Most countries operate under the principle that any cosmic material that falls onto their territory remains their property. However, international treaties and agreements enforce the idea that space material should be shared for the benefit of all nations.
Not unless there's some material matter in the space.
shearing
Not necessarily. A sphere is a "space" figure, but is not made up of planes.
Some planes have only one intercept.
If there are two unique, non-parallel planes in space, they will intersect, and their intersection will be a line.
Prism
The density does not change, as density is the amount of material in a given amount of space. But each piece has the same amount of space and material relative to each other.
Given a line, there are an infinite number of different planes that it lies in.
Then they don't go into space
A plane midway between the two given planes and parallel to them.
Two planes do not intersect at all if the planes are parallel in three-dimensional space.
Radio waves will be reflected by any surface where the electromagnetic properties of the space change. e.g. moving from free space into solid material.
No, the two planes intersect at a line, which is an infinite number of points.
