Erm, what if...
we send a message, but it falters out before it gets to the "aliens" and we never get a reply, then everyone would just think "oh yeah, it was all a hoax" or wtv. When REALLY, it just never got there o.o *twilight zone music* this has me a little freaked out seeing it IS 4:30, storming, dark, and I just watched Elfen Lied XD |

Why should we send them a message, assuming it was a message? If you think about it what are the odds of them, assuming they even exist which is based off the assumption that it is indeed a message (so many assumptions), even being alive to recieve the message. How many species on earth have existed for more than 80,000,000 years? Not many and those that have can barely be considered sentient. But then again let's work something out...
Conclusion: Assuming the above are correct and the nature of space observation applies, even if a reply was possible we would have absolutely no idea which direction to send the message since it's origin is no longer occupying that portion of space.If you're really hoping for some form of alien contact, put your hopes in to something tangable like the Galileo space craft's disk. |

Back to my previous question, are radiosignals sent in a small area, or a wide area? (Graphic Explanation may be required)  So, my question, is the radiosignal more like #1, or more like #2? If it's more like #1, then it is more susceptible(sp?) to be reflected (and perhaps distorted) by other planets, right? (And yeah, proportions are way off, and no, the other planets are on the other side of the sun  )

Necrodeath: You can send radiosignals in thight beam, and you can send them in all directions, like normal radiobroadcasts.
Usually in space exploration, when ground control communicates with their satellites signals are send in a beam, so it requires less energy as you can focus the beam (like a laser). Planets and stars stops signals, but they are very small compared to whole sky, except Moon and Sun, but since they move quite quickly out of the way, its not a big problem. |

According to the Superstring Theory, our universe is composed of 10 dimensions (hyperspace, could also have 11 or 26, but in Modular Function related to SS, 10 keeps on popping up, so....). Three physical dimensions (up/down, left/right, front/backward), one time, and six other all curled inself up to Planck Length (1.616 × 10-35 m) while the 3 dimensions as we know it expanded to fill the remaining space. Therefore the theory state that the 10 dimensions are all around us ^_^ . I could go on forever with SS but... Or your could try the Brane Theory but again... Back to the question. Even if you know which direction (arc) the signle comes from, many factors comes into play when you are talking in millions of light years (where Quantum Theory dim and Relativity Theories comes into play, therefore I will just concentrate on RT). First if all, mass can cause a bending in space-time fibric (which is why my room is becoming a black hole) and cause the wave to go (relative to us) crooked line. You could try to find every obstacles along the radio's route and try to compensate for the error. But without knowing how far might the signal originated you might as well try to locate a secret alien in the middle of Pacific Ocean. Second of all the Red Shift (Grade 9 science XD) will affect the signal. You could see the problem here. How do you know the signal is really intended for us little earthlings? The RS will dispoportionate the signal's wavelength long before it reaches earth. For us to understand the signal, the "alien" must send the signal in antipation/calculation that signal will be 'corect' by the RS in order for us to detect it. Now think, if they have the technology to do such a thing, why not just get a god-damn space ship, come to the solar system, and send the signal, for example, from Mars? PS It almosts make me cry in happiness when I saw Stellvia of the Universe that they got the basic of SS Theory right  .PS 2 YES I know this is nerd to the extreme. sue me for knowing this :X

Dammit, I have lost the battle of the nerds! They really teach that in 11th grade physics? At my old high school we took physics in 12th grade and in the honors class the most advanced topic we come to are particle accelerators. All of the above I had to learn on my own thru reading a book. I just started the next chapter which finally gets into superstring theory

Ahhh ok then. You were talking about the electromagnetic spectrum and not Einstein's general and special theories of relativity. Phew, that makes much more sense now. haha, we should start a club for physics nerds! Nerd lambda: "Gravity!" Nerd omega: "Quantum Mechanics!" Nerd E = m*c^2: "Superstrings!" Nerd F(f) = mu(s,k)*F(n): "Spatial curvature!" Nerd dF = G*dm(1)*dm(2)/(r^2): "Big Bang!" "When your powers unite, I am Captain Einstein!!!" |

Just wondering is the "alien signal" being talked about here the single pulse that was detected for a few seconds back in the 70s, then never seen again, no matter how many times they tried back at the same star?
In any event, it's far more likely that it was some unknown or known, but little understood, natural phenomona that caused it. If we were really getting an alien signal, it would likely be a few short bursts every now and then for a few years, becoming more frequent and stronger until it became a constant flow of alien tv and radio stations. Of course this is assuming an alien civilization is close by, as signals do degrade. It's much more likely we'd get these stray signals than a 'hello' from an alien civilization.

Dudez, we needz the alienz to come so that the nationz of the world will build the giant mechs that are our only chance against them. And of course everyone knows that anyone that's 16 or older can't pilot a mech because (insert bullshit nonsense here) meaning that all those anime watching kids can finally achieve their dreams!!! If you are not going to do it for the aliens, and you are not going to do it for the mechs, at least do it for their dreams!!!!

Sending any RF (radio-frequency)-based signal to space is like throwing a piece of rock into the ocean, no one will ever find it.
IMO, the only way to signal across galaxies would be the use of simultaneous supernovas, and if an alien civilization was that advanced enough, they'd have done it. |

) and that this is the "universal speed limit". In other words, nothing can ever travel faster. Because light travles thru space at the speed of light, this means that it can not travel thru the time dimension, and thus does not age. If you were to board a spaceship and travel 99.9999% the speed of light for just a few minutes and then come back to Earth, you will find that a LOONNNNGGGG ass time has passed on Earth. Essentially, the faster you travel thru space the slower you travel thru time. So since I'm sitting here typing and not moving, I'm traveling at the speed of light thru time (I'm using the Earth as my frame of reference, so yes I know my velocity is not really zero). 
, oh and get my anime of course, thus problem solved.
