Dyson Sphere

[scameter]

I was reading a physics book today and i read about something called a Dicenson's Sphere. could someone who knows what that is explain it to me?

sure you don't mean Dyson Sphere? I just googled dicenson's sphere & got zip. A Dyson sphere is a sphere you build around a planet to harness solar energy. Escher drew this Dyson sphere (click here) (http://www.tabletoptelephone.com/~hopspage/EschrDys.html)

[scameter]

yes, Dyson! please excuse my mispelling.

[sonrisa]

please excuse my error too. A Dyson sphere is built around a star, not a planet. Click here (http://users.rcn.com/jasp.javanet/dyson) to see more Dyson spheres.

If you really want to know everything about Dyson spheres (but are afraid to ask) click here (http://www.research.lifeboat.com/dyson.htm)

yeah, that's true. the Dyson sphere, i have recently discovered, is as you describe it, with the edition of the sphere around a star instead of a planet thing, which is true.

If we had the technology to build a dyson sphere. would it not be more efficient to create artificial planets that follow our orbit?

It would take less matter to produce each indevidual planet and we know what we have works. without the need for all of the extra matter (and maths) that would be needed to sustain an atmosphere.

But what effect (if any) would these planets have on our gravity and therfore our orbit?

also how long would it take for the surface to become habitable?

[scameter]

possilby, but i would rather rely on what nature gives me that that fr which humanity can create to arteficially resemble what nature gives me.

looks like the apparatus in the film contact.
