SETI Running Out of Money
New submitter opusman writes "According to an Australian space analyst, SETI is running out of money. Despite needing only $2 million a year, a relatively small amount in space industry terms, they are facing a financial crisis. From the article: 'Getting on board a spacecraft is tricky. There are few places for professional astronauts. Even when Richard Branson and a group of other visionaries makes space tourism more affordable, it will still cost huge sums to fly. But getting a foothold in the greatest quest of all can be done for just a few tens of donated dollars. Which is why it beggars belief that the SETI quest is on its knees.'"
It's quite sad that this happens now, when with the recent discoveries in exoplanets SETI could have actual targets for the first time instead of trying to find a needle in a haystack.
I can put my hard-earned money towards:
a) Fusion research, which might work in 30 years, or
b) SETI, which will NEVER find ET.
Guess where I'm putting my money.

Or something else entirely. Look at our own communications, which are rapidly switching to all-digital. Unless you know how the digital is encoded/modulated/carried, all you're going to hear is random noise. And who says aliens use anything like we do?
I postulate that a technical civilization would only stick with radio for approximately 100-200 years before moving to something better -- and something that we probably don't even know how to listen to. When measured against just the age of our local group, that's very narrow odds.
Be better to spend the money actually GOING to the stars than just listening to them, in my opinion. :)
Cogito, igitur comedam pizza.
The question is not will all alien species use radio, neither is it a question about the relative benefits of going to the stars vs listening to them, the cost of going to the stars is currently around infinity, which means if we could afford to go to the stars we could afford to finance the seti project and still have enough money go to the stars.
The question is this: is it worthwhile spending 2 million per year listening for radio signals from other stars. I think it is, as 2 million is such an insignificant amount of money in terms of humanity's resources. We probably spend that each day on cocktail umbrellas.

you miss the point entirely.
it's not that we expect to overhear their personal or broadcast communications so much, but rather it's about listening for "hello, here we are" broadcasts or even directed transmissions. we can now locate habitable planets. such messages obviously wouldn't be encrypted, and would necessarily be something very simple that would have a high chance of being understood by completely alien species with different thought patterns, senses, and levels of technology.

Citation please- gravity is limited by C the same as light is, as far as I'm aware. C is the universal speed limit for all types of matter and information, not just light. Yes, the Earth is attracted to the Sun by gravity as it was 8 minutes ago. This does not cause Earth to fly off into space- for Earth's purposes, there has always been a Sun 8 minutes ago around which to orbit.
Faster than light communication is as firmly in the realm of sci-fi/fantasy as is faster than light travel, I'm afraid. Until someone comes up with a sensible theory for another method of communication, we might as well pin our hopes on the EM spectrum.
