Hi Skybuck !

I'm sure I've seen this idea before. Here you go :
news:cf4c422.0408151419.5aabf13@posting.google.com

It's a nice idea, but the problems with this system are as big as it's size :
(1) the system has to be huge (at least Jupiter size, and you even propose an around-the-sun shield).
      So the benefits would be have to be huge for any civilisation to construct this.
      Tell me some of the huge benefits, and then check if these benefits can be obtained with a lower-cost solution.
(2) Modulation speed (bits-per-second) might be hard to obtain. If you modulate the thing with 1MHz,
      then it is likely that nobody will obtain the message, or even notice the existence on the shield.
      A far-away observer will just see a 'slightly dimmed' yellow star.
(3) Modulation is a problem by itself : if you use a mechanical device, then speed wouold be restricted
     to a few bits/sec. If you use liquid crystal or so, it will be immensely expensive, and probably
     impossible to find enough material for a around-the-sun shield.

Overall, there are most certainly lower-cost solutions for an interstellar communication device.
So the real problem is cost. That's why the probability of such a system being constructed anywhere
in the galaxy will be extremely low.

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.

Yeah... because I don't believe that radio signals would ever get to the
other side of the galaxy... to much noise and stuff... so it's unrecnogzible
blabla whatever :D

So instead one needs a BIG, POWERFULL, SIGNAL ;)

And I think the sun is a pretty good BIG,POWERFULL, SIGNAL ;)

FUNNY EH......

BUTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT
TTTTTTTTTTTTTTTTTTTTTTT

Has anybody ever though about analyzing stars ????

Maybe other aliens have already though up the same idea ;)

Maybe aliens are already trying to send a message to us by using the stars
!!!

Since we CAN see the STARS ! even from earth hehehehehehe.

So has anybody really analyzed the light from stars... if they contain
messages from aliens ?

Bye,
  Skybuck.
