The discussion revolves around the effects of a pressurized environment on the rotation of objects, particularly in the context of stopping a spinning object. Participants explore theoretical implications and practical applications related to rotation in both vacuum and pressurized conditions, with a focus on space debris management.
Participants exhibit disagreement regarding the feasibility of using a pressurized environment to stop rotation, with some questioning the logic behind the approach and others emphasizing the conservation of momentum as a limiting factor.
The discussion includes assumptions about the behavior of objects in different environments and the implications of physical laws such as conservation of momentum, which remain unresolved.
By what means? Changing the shape of the object?BAUCE said:the goal would be to achieve the fastest time in stopping an object from spinning.
thinking along the lines of trash in space. in order to reach out and grab a piece of debris, either it has to stop spinning, or the rotation must be matched. my thought is that rather than 'grabbing' it, surround it and pressurise the space around it so to stop the rotation.A.T. said:By what means?

Sorry, but this doesn't make any sense to me. Why would you do it?BAUCE said:thinking along the lines of trash in space. in order to reach out and grab a piece of debris, either it has to stop spinning, or the rotation must be matched. my thought is that rather than 'grabbing' it, surround it and pressurise the space around it so to stop the rotation.
That won't work because of conservation of momentum. We don't know your background.
