"Natura abhoret vacui" is a very old misconception. At 0 degrees Kelvin,
nature has no problems with vacuum.
What is commonly percieved as a pulling force of the vaccum is in
reality a stronger pushing force (due to collisions of molecules) from
the high-pressure region than from the low-pressure region. As a matter
of fact, *both* exert a pushing force.
