This was timed on atomic clocks and is real. Would it not make more sense to transmit at x300 plus times the speed of light(x300 c) to Aliens. They would of course have the technology to detect such transmissions. Further by entangling such atoms with those in the lab we would be casting a net in the cosmic sea which would allow future instantaneous message exchanges for the future !. Such a system would allow teleportation of Q-bits of data at infinite speeds. With even our current attempts at building Quantum computers we'd be `within range' of being able to have a meaningfull exchange with them. Our super-smart aliens(or `been there before us') would then recognise that we had arrived. Best Regards Chris. Harding Australia. Dear Sir(s) etc.:

They probably think by sending information to another species in the universe that they may be attacked by them.

Cosmic distance and most likely rarity of intelligence capable of the most advanced means of communication is responsible for SETI's failure.

I once tried roughly to esti-mate the rf TX-power necessary for reaching 100 ly´s into the cosmos from Earth. At that distance there could probably exist intelligent listeners according to the Drake formula. I got a TX-power of at least E20 watts when consi- derig vacuum qualities for the space. It may be wrong, but rises premonitions of rf power not feasible on Earth to day. If we are not ca- pable, neither Aliens very likely are not. As long as authorities avoid discussing this es- sential and logic matter, it should be accep- table that listening for alien signals looks to be very worthless. Kind regards !

We need to send a signal that we are ready to eat before we exterminate ourselves, which would have wasted the efforts to grow us for dinner in the first place. Turns out dinosaurs and fish don't taste as good as humans. That's where the mayans went.

Regardless of how advanced or how backward a civilization may be, the bottom line is that they all share one thing in common.Namely, that it's first priority is survival above all. I have news for you hucksters. Regardless of how advanced or how backward a civilization may be, the bottom line is that they all share one thing in common.

Namely, that it’s first priority is survival above all.
