Which constant should we send to aliens?

[JasonRox]

Actually, I think a good start for the data you send is:
1010101010101010101010101010101010101010101010101010
followed by
11001100110011001100110011001100110011001100110011001100
111000111000
etc...

You know, so they know it's not random.

Who said they would think it's random?

Now, you got them all hooked on what the first number is. They'll feel stupid for not knowing and never contact us because they don't want to look or feel dumb.

Why would we want to send them a constant? I don't think we can send them transcendental constants...I would rather send them e^ipi +1 = 0 too :)
