Better than the Internet.
With modern tech, we can probably produce a better data package for extra terrestrials to find.I agree about the giant holodeck.
Space is far. Maybe we will be able to fold-space time for faster travel eventually but upon the first successful fold the solar system will undergo a violent rearrangement instantaneously wiping out all life, sans that on the space traveling craft.
Safety first. That's why the Event Horizon traveled out past Neptune before opening a doorway to hell.I just realized how funny it is that I separated "extra terrestrials" into two words. That separation changes the meaning from "aliens" to "auxiliary earthlings."
