I have no qualifications in science but find it fascinating in general. Could anyone answer the following for me?
Imagine an immensely strong pipe closed at one end with an airtight piston pressed tightly against the closed end.
(a) Is it possible to pull the piston any distance along the pipe using a powerful engine?
(b) If so, is there a limit as to how far can it be pulled?
(c) Assuming a perfect vacuum is created, would moving the piston farther be stretching space?
(d) Is it possible to stretch space under any conditions?
Thanks
