Talk:Sci-Fi Game
ED: you just want to use those space gorilla figures you got. sounds interesting, but please, god, no smugglers and no archaeologists.
GABE: Damn skippy I want to use space gorilla figures! No but really I find the universe pretty open ended but not like over whelmingly large.
Haha, you'll notice for smuggler I did put "ugh..."!
JASON: Shouldnt a Dyson sphere be much larger than Mars? They are built around a star, so they would be utterly massive.
GABE: Yeah it might be bigger, just going off what I remember. The world has fairly poor writing. I think its like a dwarf star or something...
Edmiao my understanding is that a dyson sphere is a metal hollow sphere with a star in the middle of it. So one in our galaxy would have to be at the radius of the earth or mars or possilby larger. That is to say the radius of the earth or mars orbit, not the radius of the planet itself. Now, if you had a much colder and less dense star, maybe you could make it smaller, i don't know the details of what the emissions from a dwarf star are, is it hotter or less hot than the sun? i do know that your mom is big enough to take the emissions from any star, although she prefers dwarf emissions.
--Matts 18:48, 26 February 2009 (MST)Speaking of emissions, your mom sure likes my nocturnal ones.
Edmiao that's interesting. most boys stop having nocturnal emissions in their early teens.
JASON: Matt is pretty much a boy, so it makes perfect sense. If he was meaning at the orbit of Mars, that works. Really, a Dyson sphere surrounding a dwarf would not be worth the time it takes to build it. The reason you would construct a sphere of this nature is to capture ALL of the emitted energy of the star. Early in the life of a star the heavier metals can produce tremendous energy burning these complex nuclei, and this energy causes some expansive force. Stars begin to collapse when their weight causes an inward force which is greater than the electromagnetic force which keeps electrons from being near one another. This is the first stage. It continues if the star after its initial collapse has radius greater than about 1.4x of our sun (Schwarzschild Radius). If the star meets this limit and continues to collapse It now must contend with the weak nuclear force which is much stronger than EM. I dont remember the constant, but its called Chandrasekhar's Limit. When a star meets this it becomes a neutron star (Neutronium=1,400,000,000,000,000 G/CM3). The most massive stars can continue to collapse if the combination of their mass and the momentum from their continued collapse can overcome the strong nuclear force. Then you have a black hole (escape velocity exceeds the speed of light). Once a star begins to collapse its lifespan is pretty much near its end. They do attempt to save themselves by nova and supernova explosions, which would yield extreme amounts of energy, but would probably be fatal to those living inside the sphere.
This is the first time I have been able to use this knowledge since high school. I used to want to be a cosmologist.
Yay!
Edmiao my hero!
