Physics, Astronomy & Cosmology / What does a pressure in a vacuum mean?
« on: 04/03/2013 16:30:24 »
Been wondering how to define a pressure to a vacuum?
Have we experiments defining it?
The stress energy tensor mention it, and I saw someone giving it 'gravitational implications' too.
Would that include a vacuum (space).
How?
