Laser instead of TV transmitter, and Proxima Centauri instead of Alpha, but that’s basically the plan of Breakthrough Starshot.

And vice versa, as not only our earth’s transmissions fading, they are intermittent and their source location constantly moving with both the rotation of the planet and the planet’s orbiting of our sun.

As of today, they are now estimating about 150 stars within 20 light years (http://www.solstation.com/stars/s20ly.htm), and 56 possible within 32.6 light years. Perhaps a generational craft en route to one exoplanet, e.g. Proxima Centauri b, subsequently detected radio signals from earth.

It would seem logical to launch a satellite or spacecraft of some sort in the southern Hemisphere (where Alpha Centauri is) towards Alpha Centauri with a 110 million watt television broadcast transmitter…is this possible or has it been done?

I’ve never understood the use of TV signals as a first time introduction from us to any alien out there. Wouldn’t Morse code signals and radio be first and a stronger wave than TV signals. If suddenly picked up by another very distant receiver it would still be an anomaly.

I was having similar thoughts. there you have an actual case for extermination of noisy neighbours.

I wonder how many alien civilizations we humans have annoyed with our noise pollution…for all we know our radio and television broadcasts might interfere with some poor aliens thought processes or hearing….go stand on any sidewalk next to a busy road and try talking to someone while endless cars and trucks speed past belching noise from exhaust,tires on road,loud radios,horns…lets hope we don’t get a noise violation warning on our first contact.

May be they find it in the same way as we founded WOW! signal.

Good self-catch, Jim. Prime numbers are prime in any base. More exactly, a set contains a prime number of elements if it cannot be divided into any set of smaller sets, where each of the smaller sets contains more than one element and exactly as many elements as every other smaller set. Note that you don’t have to represent the number of elements in the original set in any particular base. In fact, you don’t need a numeric representation of that number at all. Whatever that number is, it’s prime if it meets the criteria I’ve outlined.

What I’ve never understood is why they used two different numbers. Yes, you can only reconstruct the diagram if you lay out the dots in a 23-by-73 grid, but it only works if you use 73 rows of 23 dots. If you lay out the dots in 23 rows of 73 dots, you get a horizontal phase shift and the picture is nonsense. That wouldn’t have been an issue if they had squared a single prime number and made the grid, say, 41-by-41. The message would have been almost the same size (1,681 bits instead of 1,679 bits), with no way to get it wrong at the receiving end.

I get a lot of static on this channel

I doubt it. I think the aliens will find organisms that like to over-reproduce to the point of destroying their environment. The question is, what group will the aliens classify them under via their taxonomy? A virus or a Cancer?

Do you think they’ll ever find intelligent life on earth? (-_-)
