An unbreakable pole in an infinite vacuum refers to a hypothetical scenario where a pole is placed in a vacuum with no air resistance or external forces acting upon it. In this scenario, the pole would be considered unbreakable because there are no external factors that could cause it to break.
In theory, a pole could be considered unbreakable if it is placed in an ideal environment such as an infinite vacuum. However, in reality, there is no such thing as a completely perfect vacuum, and there will always be some external forces that could potentially cause a pole to break.
In an infinite vacuum, there is no air resistance or external forces acting upon the pole. Therefore, the only way to move the pole would be to apply a force directly to it, such as by pushing or pulling on it. This force would have to be strong enough to overcome the pole's inertia and cause it to move.
If a pole that is considered unbreakable in an infinite vacuum is placed in a non-infinite vacuum, it would likely experience external forces such as air resistance or gravity. These forces could potentially cause the pole to break or bend, depending on the strength of the pole and the external forces acting upon it.
Studying an unbreakable pole in an infinite vacuum allows scientists to test the limits of materials and understand how they behave in ideal environments. It also helps in the development of new materials that could potentially be used in extreme conditions, such as in space or in high-speed transportation.
