In moving from the more conventional romance narratives of her earlier stories to what she understands as a kind of new fictional truth, Cavendish uses astronomy to define the boundaries of her Blazing World  Modeling the experience of reading on that of looking into the telescope allows Cavendish to define her fiction in a way that also questions astronomy's reliance upon unverifiable visual evidence.
In the opening pages, readers would already expect the Blazing World to be an alternative romance world.
The suggestion that astronomers could see the Blazing World through their "very good Telescopes" in the same way that they sometimes see "two or three suns at once" transforms scientific discovery into optical illusion.

In The Blazing World, by contrast, Cavendish intends the reader to see things which would not be visible in any lens, however powerful.
While the construction of the Blazing World affirms the power of natural vision, the scientific practices of its inhabitants demonstrate the limitations to artificial technologies.
