Can a Balloon be Filled with Vacuum in a Vacuum?

[Ender55]

Could a balloon be filled with vacuum - in a vacuum?

And if a balloon was filled with any other gas and put in a vacuum, it would just expand until it popped, no doubt?

From how I am thinking - a vacuum and a vacuum would have same pressure so the balloon would neither inflate or deflate.

As for the gas question - yes it would eventually pop. Becuase the pressure outside of the balloon would be much lower than the gas inside.

If a balloon was put in a vacuum with a very small amount of air in it, it could just expand a bit until the tension in the balloon was sufficient to sustain a somewhat small pressure differential between inside (some non zero but very low pressure) and outside (zero pressure).

Okay i should of said the amount of air is a factor but yes it does expand the balloon :P

No, a balloon cannot be filled with vacuum in a vacuum. A vacuum is the absence of any matter, including gases, so it is not possible to fill a balloon with it. Additionally, a balloon filled with any other gas would indeed expand in a vacuum until it eventually popped due to the difference in pressure between the inside and outside of the balloon. This is because gases will naturally expand to fill the available space, and in a vacuum, there is no outside pressure to counteract the expansion. Therefore, it is not possible to fill a balloon with vacuum or any other gas in a vacuum.
