A spacecraft with solar arrays and a large battery is
landed on comets of long orbital duration. When the
comets are at apogee the spacecraft will broadcast
vile
thrash music on various frequencies to the extent of
the
battery. Upon return to our orbit the solar array
will once again charge
the battery and transmission
will
again commence. Scientists will check to see if the
system is working, if the playlist is the same or has
been
reprogrammed, and whether the entire contraption
has
been vandalized or removed and replaced with something
else.
A serious version of this idea in reverse.

One slight problem: comets don’t leave the Solar
System. |
|
| |
If they flub the course, do they release a apogee
apology? |

Basically, the idea was to have a sort of indicator or beacon
on something that regularly reaches far beyond our usual
monitoring area; a comet with a decades-long orbit would
do nicely. While we have sent out interstellar probes
containing our information they're only useful if aliens wish
to plot a return course. But a passing alien on its way to
Magrathea could interact with a comet-mounted device and
never have to visit us in person. |

If interest is peaked, having a quick peak at a lone piece of technology is far better than dealing with the mess. Also wouldn't this be a set and let amateurs check deal, as technology will advance as the centuries pass. |

What's wrong with "apoapsis"? |
|
| |
You don't have to stop just because he's not here. |
|
| |
At least it isn't a way to modulate the Sun's
brightness |
|
| |
If someone is just passing through, we can't make judgements on their level of technology. |
|
| |
This silly idea originated while studying the Voyager deep
space probes, each containing information on humans and
Earth. Intelligent species could intercept a probe, learn
about it and us and perhaps plot a reciprocal course to
visit us. And since both probes were launched over 40
years ago perhaps this has already happened. |
|
| |
The problem is that the probes are one-way emissaries;
aside from their continued meager transmitted info have
they encountered intelligent life? Using what we have,
how could we send something a great distance and have
it return, and know if it had some effect? |

//We can't.// I was always told, "there's no such word as "can't"". I used to think that was slightly paradoxical, mind. |
|
| |
If the Extraterrestrials are even into our radio waves rather than moving tiny unnatural specks against the void. I would have thought a thorough grounding in void dynamics would be fundamental to interstellar engine design. |
|
| |
In my opinion FTL really is impossible, meaning time dilation via going super duper fast (a technical term), robots, and generation ships are the only way to go. Those don't necessarily need any understanding of void dynamics. |
|
| |
Even going near super duper fast will need an understanding of the traversed space. Although, void dynamics may open higher dimensions. Or at the very least, help access to exceptional amounts of energy and the control thereof. |
