So those of us that deal with science fiction have all seen space ships that can't be detected until you bump into them or physically see them. The project RHO website is commonly referenced when this topic is suggested.
Now before I explain, let me go over what has to be hidden for stealth in space to work.
- The heat from everything inside and outside the ship
- Mass and the resulting gravity
- All emissions, engine, weapons, life and life support, everything
Many many writers and other individuals have tried to figure out ways to hide something of a star ships magnitude.
Black paint doesn't work, Diverting the heat doesn't work, Bending light doesn't work, pretty much everything doesn't work, as such you can't have stealth in space.
Then don't be in space. If you're not there, you can't be detected. You have nothing to diffuse, no mass to hide, no heat to divert. But you have to be somewhere, preferably close to space. How?
Just shift out of realspace.
For the purposes of this idea, assume that this is possible on a purely technological level.
I've been working with the idea of multiple dimensions and movement between them. It occurred to me that there has to be some kind of space between dimensions. It's probably right next door to where you're sitting, but you can't interact with it. Lets call it the "Nullspace"
This region is always just a step away, if you can take that step. A high level of technology, related to FTL and possibly inter-dimensional travel is required.
It's not a perfect system however:
- You're blind while doing so. You can't see back into realspace as if you were looking through a window. Even with windows, you see nothing useful.
- Sensor devices don't work in Nullspace. You can still move around as if you were back in realspace, but it helps to see where you are going. Thus usage of a extremely small probe that pokes back out into realspace allows for this.
- You can just plot a course and hope nothing is in your way when you exit, but you can't stay in Nullspace forever.
- Your probe can still be detected, but that's a lot easier to hide than an entire craft.
- Your position is only just outside realspace. You're only hiding by "stepping outside" so to speak. Powerful enough effects can still bleed through and cause problems, such as intense gravity.
Think of it as holding an object that has buoyancy under water. Except that the buoyancy increases the longer you stay under. Basically this is Nullspace rejecting your craft and trying to push it out.
So with all that said, I am seeking those with more experience on dimensional theroy.
I'm not trying to break science, I don't want to if possible
