- Put lots and lots of flexible, reflective metal plates in a half-ovoid in heliostationary orbit, thin sides facing the Sun
- Simultaneously turn the plates to face the Sun and attach them to each other so that energy focuses to the apex of the "sail"
- Gravity pulls edges of the sail towards the Sun, while the energy pushes the apex back. The focal point moves inwards, towards the sun.
- The sun starts swallowing the sail as its own energy focuses on it, applying a vector.
- After the sail has been fully swallowed, the Sun has moved in its orbit around the galactic center.
- Repeat to move the solar system more, even escape the galaxy.
- ?
- Profit.
Proooooooobably doesn't work in real life, but it sounds like it might, and that's enough for science fiction.
That's more like a cosmic jet engine than a sail.
Heliostationary orbit probably doesn't mean what you think it does. If you match the rotation speed of the sun you're still orbiting.
A static sail could maybe work, since gravity and solar pressure decay at the same strength (if you closely tuned the mass of the sail you could get it to be static with respect to the radiation pressure and gravitational force). The problem is that it's not a stable system and so you will have to constantly adjust the sail's position. Same problem as a dyson sphere, really.
you mean Dyson Torus/webs? I think thats just velocity. Right speed and the right orbit and it should stay put.
The gravity inside a hollow shell is zero, so if you put an object inside a dyson sphere it would feel no attraction. However the converse is also true--if you put a massive object inside the sphere, the dyson sphere will not be attracted by the massive object. They would move independently with respect to each other, i.e. an unstable system.
