I've been trying to find celestial phenomena that could act like nebula often do in Sci fi shows, i.e.,
- A phenomena where a ship can hide from other ships
- A phenomena which is difficult but possible to navigate and stay inside.
Nebula in reality are too diffuse to be able to do these roles, so I have found 3 celestial phenomena which might be able to do this.
- Stellar accretion disk. I'm not talking about protoplanetary disks.
https://www.nasa.gov/mission_pages/hubble/science/planet-eater.html The exoplanet WASP-12b is being devoured by its star and I'm curious if it could create a dense enough accretion disk of hot gas and charged particles to act as a smokescreen. Maybe if the distance of the planet to the star was smaller, like if the star was a white or red dwarf, the disk would be more dense.
- Mass Exchange between stars.
https://en.wikipedia.org/wiki/Roche_lobe Some binary stars systems exchange matter between themselves. This matter would be composed of gas and plasma. Could this matter be dense enough for hiding?
- Shedding supergiant.
The very outer layers of a supergiant might be cool and dense enough for a vessel to hide in.
I'm curious if any of my three candidates could fulfill the role of a nebula from scifi. And if they do, what could be the repercussions of hiding in one for the hider and seeker.
