Had an idea for an invention, but I have zero understanding of technology and physics of light, so I need to know if this will work before I carry this forward.

Basically, it would be a spinning black sphere with ridges, attached to a pole. The black sphere would be designed to absorb all the light in the area which would get trapped inside the ridges. The spinning would make sure the maximum amount of light is being exposed to all sides at all times. You would put it in your yard, and it would be like a "Reverse flashlight" where all the light around you would be absorbed into the sphere, resulting in the creation of a natural shade. Perfect for a cool summer day.

Can anyone tell me if this makes sense or if there is anything that could be done to improve it before it can work like I posted?

I'm a connnmannnn! Or maybe I'm a god! Zooming 'round the planet with my hyperloops and pods!

If Nukes exist then why has no private group managed to make them yet?
name one other technology that has been monopolized by the government.

Is picrel true?

> And why?

How come no other country in the world has landed people on the moon? Lack of ambition?

Is it possible to colonize a gas giant? There's a lot of empty space in these huge planets not being actually kinda used at all

I don’t like the idea of aliens existing since I prefer the idea of humans being the only species on Earth. What’s the chances they are real and if they are how can we kill them all?

Is there a scientific reason why online classes suck so much?

Be real with me can I re learn math at 22 (algebra onward)? I genuinely didn't try in school I know it sounds like cope for being retarded but for some reason this has been eating me alive for the past two weeks.
