[@Miata822]

Late reply, but I've gotta say it- If any civilization sought to communicate unambiguously with another over interstellar distances it seems obvious to me that they would do it by laser. Even relatively near a star the fixed and isolated wavelength would stand out. It has always seemed to me that SETI was barking up the wrong tree since no society that has survived the technological transition would throw away as much energy as is wasted in a radio signal. After a handshake and working out details we can (carefully) point Fermi's neutrino gun at a receptor on their end. Now that could really work. OK. That's all. Just had to say it. Recently found this channel. Really enjoy it. Catching up on older videos now (obviously).

very good point. "They" only tell you what THEY want you to hear. I knew about it because a very good (& smart) friend of mine was visiting London on vacation at the time and he heard about it. Yeah he wasted no time renting a vehicle and driving down there for a firsthand looksee. At this time he had NO idea that it was a "message" he was simply interested in the crop "circle" phenomena. So he actually got down on his hands in knees and examined the actual bends in the plants themselves. He stated later NO WAY was this man made! The plants were actually bent by varying degrees of damage to the stems at varying heights. The stems later healed and they continued to grow but at their new "bent" configuration. they were not CRUSHED as would have been the case had a human done it by any other means. He said the bend lines were also very precise... almost as if the plants were a cut line. There was another pictogram there in the same field but it was NOT present to his knowledge when he visited it on 8.18.2001. In fact it appeared exactly one year to the day later. Thus although these are often seen together in fact they were present a year apart thus they were obviously both not present concurrently.

Aliens cannot exist unless they are identical to us, and you know us - overpopulation city spreading our spawn as far as we possibly can - even to take over the entire galaxy one day!

Correct, the 2001 crop circle (known as 'Arecibo Reply') was confirmed to be genuine by researchers and not a hoax. All crop circles can be analized to determine authenticity by analyizing the way the plant stems are "layed over" with an expulsion cavity and by other characteristics. Man-made crop circles do not have these atributes and are easy to identify as hoaxes.

I may never "know" if there is other life out there in the galaxy, or even in the universe but I choose to "believe" that there is, as it feels like an unbearable heartbreak to think that we are all there is, and will ever be. Nevertheless, the realist in me tends to think that life is like momentary flashes of light going off across the cosmos. There one moment, and gone the next, forever causally separated by the unimaginable vastness of time and space. Thankfully, we have imagination enough to visit the far off places in our minds, that we could never hope to visit otherwise.

[@jeffclarkofclarklesparkle3103]

So, why not talk about the crop circle that was seemingly answering the initial message we sent? How they had a massive array for their radio, or that the were silicate based life forms? As well as a few extra unknown elements i believe? How can you tell all about our message and not cover it all, as weird as it may seem..

[@C.O.G.]

Seems as though our video posting friend here thinks the answering message was created by a group of "artists". That doesn't explain the fact that the grain stalks in the crop "circle" were altered so that they bent, but didn't break. Or the fact that ordinary, non scientist "artists" would not normally have the scientific know-how to create such a response as the reply message contained. SMH...

He hasn't done his homework with regards the Arecibo Crop Circle Formation and casually dismisses it as "only artists."

Great explanation. This is what I do not understand. This message was sent to the world’s BEST scientist to decide the Aricebo message. Yet, most couldn’t crack it in full. Then, a response 30 years later in the same binary code was made on a crop circle. So easily dismissed? What an elaborate hoax to give the exact measurements of another being, planets, and dna structure. Using the exact binary code. Not only would you need to know binary code in this form, but construct all this information onto a crop circle.

Excellent video! At 10:28 its a bit unclear. Better would be to emphasize that 14 is to be multiplied with the transmission frequency. The logic? The blue vertical column should trigger the alien brain to think in terms of length. Since 14 is unit less, we need units. From where? The only answer is from the message frequency. The last part should have been rephrased to "or whatever units the aliens chose to for the wavelength of the transmission frequency".

[@fastwalker128]

Very well presented and easily understood video. But all this could be all for nothing If the aliens don’t use a base 10 counting system. What if they use a hexadecimal or some other base for counting?

The presenter said, regarding the aricebo reply, "I don't want to say its artists, but its artists" and gives z-e-r-o to back that up. Probably doesn't back up the statement because all evidence points to the contrary

Yea this dudes a total fkn numbnut. Like what kind of retort was that?

[@eytansuchard8640]

Most likely that if the presenter tried to make the crop pattern himself in the way it was found, he would encounter problems. The only way to show that the pattern was made with the help of advanced technology is to examine the bent stalks.

I was thinking the same thing. If they could've proven the crop circle was man-made, they would've.
