Odd Pressure In Interplanetary Space Between Roshar and Braize?

[Bacon]

In Rhythm of War, Raboniel mentions that they tried space travel, and died

During that she mentioned ( paraphrased ) :

" the strange pressures of that place "

Do we know whether that's just normal interplanetary space stuff?

or are the pressures she mentioned Cosmere-specific?

For example, I could see something like a pressure-based storm in space being caused by a reaction between Honor, Cultivation, and Odium at that distance.

but anyway, has that ever been confirmed in either direction?

[Thaidakar the Ghostblood he/him]

it is probably just normal interplanetary stuff.

[Wandering Shade]

She probably means the vacuum of space and the weird cold boiling and stuff that happens in a vacuum

[DiePie]

yeah I always assumed it was the vacuum of space. Understand that the Fused probably didn't understand what pressure is, and why it doesn't exist in space, until the final desolation, which is why Raboniel talks about it in such uncertain terms. That Fused probably didn't even make it to one of Roshar's moons before they died.
