I'm working on building my very own Dyson Sphere. I've started ordering the concrete for the foundation from my local hardware store. I plan to start construction this week.
Now, when I told my friends what I was planning, naturally they laughed. They scoffed, "Do you even know what a Dyson Sphere is?"
Of course I do. Picture a sphere with a radius the same distance as the Earth is to the sun (presumably when it's at its closest- I'm not in the mood to build an 'elliptical' sphere). Now imagine everyone living in the inside of the sphere, soaking up all the free sunlight. Click here for more info.
Anyway, the fact I knew this didn't stop their laughter. No sir. They replied, "Then what are you going to do for gravity? Sure, you could spin the 'Sphere around and live on the "equator", but what about the "poles"? There won't be any gravity there at all!"
Ah-ha, I responded, I've already thought this one out. The shell of the 'sphere will be as thick as the diameter of the Earth... whatever that is.
Let's say for the sake of an argument that the Earth is 100 000 kilometres in diameter (astronomical pendants, feel free to correct me as to its actual diameter). By making the shell of the 'sphere this thick, it will have enough density to provide all the gravity I need.
My friends are still laughing, though. They claim that the gravity of the sphere on the other side of the sun will cancel out the gravity beneath our feet. Please excuse my sloppy way of describing it, it may surprise you to learn I don't have much background in astronomy. But imagine a ping-pong ball in space made of super-dense material. Imagine an ant on the inside of the ball. Apparently the ant would float around the ping-pong ball!
"That's rubbish!" I thought. Surely, because gravity diminishes with distance you'd still get all the gravity you need! Can anyone help me explain this one to my friends.
First, some ground rules.
I am a kook. I will not tolerate any arguments that will destroy my dream of building a Dyson Sphere.
Anyone using reasoned, well-formulated arguments backed up with solid evidence will be subject to ad hominem attacks by myself.
I will not be required to provide any supporting evidence or math to substantiate my claims. Anyone disagreeing with me will require more evidence than any reasonable court of law in the world, or I will say they have no proof to support what they are saying.
Anyone trying to get me to see reason by asking questions in the Socratic style of debate, or even if anyone just asks me a question to clarify what the heck I'm talking about, will be subject to responses in the form of questions -from me- which have nothing to do with the topic whatsoever.
Presistant attempts to get me to see reason will be met with accusations that the person in question works for the government, or a multi-national company if the question is asked on a Thursday.
Ground rules to be changed by me without notice. Frequently.
