Re: The Smoke of Purpledawn's Wrath
I wish we knew how old they are.
​
I am probably uniquely unqualified to address this question but don't gamma rays move at the speed of light? Wouldn't this make them 25k years old?

Re: The Smoke of Purpledawn's Wrath
Like Parasomnium, I though it might require the presence of a gas excited by the gamma rays. I do think gamma rays would travel the distance of the joint bubbles in 25k years, but I'm unsure about what kind of boundary that would form, esp. since the stories remarked strongly on the rapid development implied by the sharp boundaries.
​
I see what you guys are saying and that makes sense. Even though making sense doesn't seem to be a requirement of cosmology.
​
Does this then raise the question how is the gas escaping from the black hole at the centre?

Re: The Smoke of Purpledawn's Wrath
Ah I see. So the laser beams of death from PD's eyes are refracting off of the blue haze of hooah's posts.
