[quote author=“hmm!?!”]Although they express their thoughts very simply, I agree that to justify the method we are using, we need to work on assumptions that have low probabilities! We are assuming that they are sending the type of signals that we would be able to detect with our machines. We are assuming that they have evolved the same way, and are as advance as humans. We don’t know how many light years away they are, so by the time we get any signals, they may all be gone! There are too many questions that keep me skeptical about our efforts to communicate with ‘Aliens’!
The theory and the technology are fascinating, though I sometimes wonder why we are spending so much money on something that we have no evidence for! There is a possibility of alien existence, but isn’t it like searching for a God?
I need a good argument for where all the money is going (especially in the US). Can we justify funding projects to search for life out side of our earth, or how to make Mars habitable, when our planet is rapidly degrading and the survival of our species is a more immediate matter to consider?
Yes, it is all very speculative. Personally, I am “agnostic” about the possibility of contactable alien life. I believe that the universe is big enough that there must be intelligent life somewhere, but for all we know it could be in the Andromeda galaxy, and we’d never be able to communicate. (Millions of years to communicate a single message).
As for the funding, you may be surprised to know that none of it comes from the US government. The government did support SETI research decades ago, but there were arguments against it, and so they stopped. Now the research is basically all done by private funding, from organizations like The Planetary Society . FWIW, I think our government supports plenty of silly, stupid things, that there ought to be a few drops for something as potentially important (though speculative) as SETI. After all, as scientific research goes, SETI is very cheap. It’s certainly orders of magnitude cheaper than the International Space Station, which is basically useless as a science platform.
So yes, SETI is very speculative, but IMO the results could be really exciting, earth changing, if we ever did find anything. I say “why not?”; and certainly there can’t be an argument against it if it’s privately supported.
[quote author=“hmm!?!”]There is also the theory of our universe being a 5D black hole! that means we may get signals from outside of our universe, but we may not be able to get anything out! Can you believe that?
New Scientist has the interview with the scientist who proposed the idea of 5D black hole. It’s very informative to listen to! and it’s Free…
Cool, thanks, I’ll give it a listen when I have some free time. These sorts of cosmological questions are equally speculative, of course. But they are fun to consider as possibilities.
