I know that for the longest time we have been listening to radio waves for some sign of life. I also recently heard that SETI was shut down do to lack of funds recently . I was just wondering, if there is another intelligent space faring race out there that was capable of extra-solar travel wouldn't they use something other than radio waves to communicate? Aren't radio waves "too slow" for that kind of reliable communication? After all, it takes several min for radio waves to go from here to the moon, so I could imagine what a pain it would be to talk to people that we send to the nearest star. Are there any theories as to how to communicate in more real time over such distances? Thanks.
