How much available matter in the solar system?
+0
−0
Assuming all the energy in our solar system (solar energy, heat, etc) was converted into matter, and then using all the matter in the solar system, how big of a city sphere could be built?
What I mean by a city sphere, is if the builders started from the center of our solar system, consumed everything, and started building outwards, how far would the radius be? Would it reach out to where the asteroid belt was before it runs out of material?
I am assuming concrete or steel density, and not taking into account any gravitational effects.
