Dyson sphere around white dwarfs[edit]

"This type would avoid the need for artificial gravity technology, in contrast to the AU-scale Dyson Spheres. In fact, we show that parameters can be found to build Dyson Spheres suitable —temperature- and gravity-wise— for human habitation. This type would be much harder to detect." from: http://phys.org/news/2015-03-idea-dyson-sphere.html — Preceding unsigned comment added by 83.101.62.159 (talkcontribs) 16:46, 13 April 2015 (UTC)

Dyson bubble: sail density versus radiation pressure[edit]

The wording is counter-intuitive, that the density of a sail would be 0.78 g/m2, because the radiation pressure is not a constant. It varies according to your distance to the star. But in the linked reference the argument was given that as you move closer to the star, radiation pressure increases, but so does gravity, and so these effects cancel. By the way, radiation pressure of a variable star is not constant, and our sun is slightly variable. It would improve the article to state both of these facts. -- 135.23.66.249 (talk) 01:09, 30 May 2017 (UTC)
