In the Simpsons Mr burns sends a shade disc up into the sky to cut out the rays

[Dayne Malloy]

of the sun is this possible ? ----- or feasable in real life ?

 

[johnny j]

Anythings possible, remember.

 

[sean b]

Its probably possible in engineering term, to cut out the sun over a relatively small area.

However it would need to be massive and move over quite a large range.

It would probably cost trillions, so its not possible from an economic point of view
