Creating a Temporary Vacuum: Is it Possible?

[dizam]

If you were to destroy all the air around an object, would that give you a temporary vacuum or would the air be replaced so quickly that it wouldn't make a difference?

Is the object inside an enclosure? If not, air would come in immediately.

Well it couldn't come in faster than the speed of sound.

Something pretty similair happens to make thunder

No, the object is not inside an enclosure. I was thinking of any type of sealed object traveling through the sky.

Are you certain that this is true? Could you explain the logic please? So then a supercavitation type of phenomenon would be possible but with a vacuum.

Would you mind elaborating please. Thanks

Also, let's say that the object has acceleration. I know this would affect the airflow but how?
