There are certain regions that do have pressure as 3 00:00:16,029 --> 00:00:21,100 they get denser and start actually forming stars the pressure and temperature 4 00:00:21,100 --> 00:00:24,430 actually build up and this is how you actually forms things like stars and 5 00:00:24,430 --> 00:00:27,320 planets throughout space.
