Ayn Rand presents us with the axiomatic concept of Existence. It cannot be refuted. And if it exists here it must exist throughout our Universe and beyond. It is infinite. And if it exists here now, it must have existed from an eternity past and we can assume that it will exist for another eternity. It is eternal. Finally, as it exists here now, after an eternity of burning, it must possess a mechanism whereby the ashes of the burned up stars are transformed into new galaxies, at an efficiency of 100%.
This Cosmological Model can be found using the evidence found by the astronomers over the past centuries, but stated in scientific language. Think about it. No magic needed.
