SETI may not be the way!

Nope. Tachyons are purely hypothetical and even if they do exist they could not be used for superluminal communication.

I know! Quantum Entanglement=interstellar telegraph lines.

Nope. Quantum entanglement does not allow superluminal communication, either. You only get one shot at creating an entangled state. You must encode the information while creating the entangled state. You then have to transport one of the entangled elements to a remote site. The remote site can read the encoded information, but it got there subliminally. You can't encode the information after creating the entangled state because the act of doing so would act to untangle the states.

Anyone get back to you on this yet?

 

Stranger: Of course nobody knows for certain about the existence of intelligent life elsewhere in the universe. Nobody can even be certain that there is any life at all elsewhere in the universe.

There is no observational evidence and no currently known experiment which could provide a clue.

In spite of the above, there can be good reason to consider one point of view more likely than others.

Suppose that a scientific breakthrough was announced relating to quantum tunneling (worm hole, what ever) technology that was capable of providing an accurate view of any place in the universe. Of course, it would take months to build the devices to use this technology, and it would take perhaps 5-10 years to view enough places in the universe to provide a good estimate of the abundance or scarcity of life elsewhere. .

Given the above miracle of technology, there are those (me included) who would be willing to bet that life was very abundant, scarce, or non-existent elsewhere. Similarly, there are those (also including me) who would be willing to bet on the scarcity or abundance of intelligent life.

If I could find some one willing to take the bets, I would bet more than modest (but not exorbitant) sums as follows:

• I would bet that life was fairly common in the universe.
  
  
• I would bet that intelligent life was rare in the universe.

I would surely bet enough to hurt if I lost, but not enough to cause financial hardship.

Would you take either of the above bets ? Would you merely say: “I do not know & it is silly to even think about the issue in the absence of hard definitive evidence.” ?? I will wait for the views to be reported before having any opinion.

As mentioned in a previous post, the history of the Earth provides strong support for the above views that I would bet on.

 

There's a place you can bet that sor of thing on the internet, legitimately and all. Goodbets or something like that. Try googling it.

It would be an interesting state of affairs if all civilizations in the universe were within 50 years of our own technology, and we're all busy listening for each other.

It is freaky how you can make such a leap from your 1st 2 sentences to the rest of your post.
I wouldn't be willing to bet either way. If somehow I was forced to bet, I'd bet intelligent life is abundant.
I certainly don't say it's silly to think or talk about it or even form the best theories we can at this time & place. It is silly to think we know or that we even have many clues at this time & place.
We won't know until we either have some technology as you mention or until we actually get out there & explore much of our known universe. Much much more than our local galaxy group.
The history of Earth barely provides us with a few clues upon which to base temporary suppositions.
If I lived at a time that travel thruout this galaxy is easy & fast & we know intelligent life is very common in this galaxy, I still would not know whether it is common in most of the known universe.

 

If I am not mistaken, SETI is not looking for "radio leakage" -- it is looking for radio signals deliberately designed to be picked up by nascent technological civilization such as ours.
