Original Note:
In physics, vacuums don't "suck", but rather higher pressure pushes into lower pressure areas. Gravity pulls air molecules toward the earth with more force than the molecules exert to push themselves into the vacuum of space. https://www.forbes.com/sites/quora/2017/05/16/why-doesnt-the-vacuum-of-space-suck-up-earths-atmosphere/ No physical barrier is required.
