Sure but would not the particles from solar flares pass thru
a Dyson sphere as an 8 inch shell passing thru kleenex?

Is it too late to think up any new twist on the idea of Dyson
spheres/Matrioshka brains? Here is one that is kinda a hybrid
that I havent heard:
Suppose you want to facilitate communication between
the nodes of an M-brain with a waveguide of sorts, a little
like wires between the nodes. If the wires are taut, you
must go with active control systems to deal with the orbital
instability. But if the wires are really loose and slack, so
that the distance between nodes can vary as required to
maintain orbital stability, then no control system is necessary.
Imagine nodes about a meter on a side and a few microns
thick, a 100 meters apart with a cable the thickness of a
strand of spider web, loose and floppy, perhaps 500 meters
in length, over which signals can be sent. That saves us a
guidance system and lasers to communicate between
nodes. Perhaps we could use a graphite tube a micron
in diameter, or nested bucky tubes as the waveguides.
Of course the communications between nodes would
be slowed by a factor of 5, but this might not be such
a big problem. spike
