To the best of my recollection, the "Welcome Wagon" a helicopter fitted with two rather large boards with rows of light bulbs built into them, with
one board on each side of the helicopter. The signal I recall them giving the aliens appeared to be nothing that would seem like a communication. If
it was a communication, it would seem to have been saying "fire on this craft first" or "this light thing may be a weapon, watch out."
I really can't imagine successfully using such a lighting scheme to inform an ET of anything we would want it to be made aware of. It's just too
hostile, and unlikely to be interpreted properly. So I don't think the creators of Independence Day were onto anything there, unless I'm just not
remembering the scene correctly.
I must say though, I could see light as being an application of dialogue with a form of life unable to speak a common language other than mathematics.
Much like how morse code was and is still used today, we could send a message in the form of light using binary, the alleged universal language. All
that would be needed would be a device capable of emitting light, a power source, a message and an on/off feature.
We could send whoever may be watching a combination of 0s (off) and 1s (on) which could be translated by the receiving end to mean whatever we felt
the need to say to the intelligent universe. This of course, has already been done. We have sent messages in the form of binary over radio broadcasts
intentionally directed into space hoping someone or something will intercept and decode them.
So, we could use light to speak with ETs already on or near the planet, sure. It would be rather difficult to send them a message in the form of light
into space, though. The sun is to great a source of light for us to compete with, it would be difficult if at all possible to see a pulsing light
coming from SOL. Even if somehow it was noticed, they would have to have reason to believe it was more than just a twinkle, or other natural
occurrence before they would begin to analyze and attempt to discover the message we have sent.
This has been considered in the past by the scientific community. "If nothing is faster than light, then lets use it to talk with our galactic
neighbors." Shortly after the thought and proposal, the flaw was noticed. I believe they have been working to refine the idea and find a way around
the Sun problem, but it seems like we might as well just use microwave and radio messages for the time being, as simple light seems too unlikely work
As far as sending out satellites goes, we could do that with little expense in the foreseeable future with the help of Nano-Technology. I don't know
it will be too helpful to us though. Earth trying to communicate with an advanced civilization using satellites or probes seems like no better of an
idea than telemarketers trying to interest you in their product via smoke signals. We should be sitting here waiting for them to come to us instead of
actively seeking them with technology which is hardly likely to be even compatible with their own.
In my opinion, they already know our number if they're looking and if they haven't given us a ring yet, then they aren't gonna call. We shouldn't
waste further time or resources trying to get their attention. We should just sit back an listen for a reply.
