Heavens Without Pillars
I believe it is the 6 heavens above us that are supported without pillars. We are at the lowest heaven; which is the only one having the lit up stars. The other 6 do not have lit up stars. All these heaven do not collapse onto each other as they are supported by something other than visible pillars. Even in our universe all the starts and galaxies do not collapse onto each other without any visible pillars. Scientists think it may be the dark matter that might be supporting them.
