Why does the 1 AU Dyson sphere needs to be that much thicker (more than 625x thicker to be precise)?

Why does the 1 AU Dyson sphere needs to be that much thicker (more than 625x thicker to be precise)?
- danieltillett 9y agoThe inner shells need to be thicker for three reasons - photon pressure, they are at a higher temperature, and the wavelengths they are capturing are shorter. Having said this they would not need to be much thicker than the outer layers.
- _Codemonkeyism 9y agoSo a.) The inner layer is thicker than the outer layer, but not much b.) The outer layer has a surface area 625x larger than the inner layer c.) The outer layer needs only a "small increase in resources" I still don't get it.
- danieltillett 9y agoThe only thing we get to observe is the outer layer. We really have no way of knowing what is going on inside or what structures are present. The relative small increase is not in reference to a smaller sphere, but to the material resources of the stellar system. If you only need 0.00000001% of the material resources of the system to build an inefficient sphere then using 625x more is not a significant increase.
- tboughen 9y agoWe tend to assume that one would want to be able to walk and live inside a 1AU Dyson sphere, so structurally it would have to be sufficiently strong to support such uses.
