Hi,

Seeing all the bullshit in this newsgroup or maybe sci-fi... or maybe

future

technology I thought I add some of mine hehehehe.

My idea is to use the SUN as a way to send a message to aliens ;)

We build a big shield around the sun. And then we can turn it on and off
like a lamp.

   It's very easy to write a sentence like that.....

   A shield made of what? Surrounding how much of the Sun? At what
distance (which will have a lot to do with its mass)? Are you talking
about some kind of billion-mile wide Venetian Blind? Have you any sort
of idea about how hard it would be to make something like this move in
unison?

That's for 'the scientists', 'the engineers' to figure out =D

But I'll contribute a bit ha-ha.

What is the sun made of ?

Maybe it's like lava like earth ?

The sun is primarily a 75%/25% hydrogen/helium mix.  Bismuth boils
at about 3000K; the Sun's surface is about 5800K.  (The corona
is far hotter but less substantial.)  Spot the Engineering Difficulty.
(Actually, there are two: getting close enough to play scoop might
be a little warm, too.)

Maybe we can 'scoop' some of this stuff up and use it to construct the
shield hehe.

Not horribly likely.
