Reminds me of
long time nuclear waste warning messages intended for humans. I have no idea about the viability of the idea, but it's absolutely fascinating to read about any effort to communicate something to a mysterious unknown party you know little about. But it turns out to be exceedingly difficult to do even when the target audience is humans. Talking to aliens raises the level a thousandfold. Although the
Voyager golden records are remarkable in that regard, it's mind-boggling how much information a simple diagram to the back of the record is able to convey, and how universally it's coded (albeit the universality of the message may be challenged when an actual contact with aliens is achieved – but at least it
seems that anyone possessing a critical mass of knowledge should be able to decipher it).
The concept itself makes me wonder about somebody else – non-human animals. Some non-human creatures on Earth are really smart, rudimentary language is possessed by many (all?), some are speculated to possess more than rudimentary (e.g. the Wild Dolphin Project decadelong observations and recording of dolphins vocalizations inaudible to humans have noted features likened to syntax and personal names, but little to nothing has been deciphered or assigned a meaning)... So, emojis being mocked for being the most primitive braindead form of communications, has anyone in history ever communicated a message to an animal using a visual sign that the animal hasn't been taught to recognize? Excluding when it's
communicated through deception? The idea sound so absolutely ridiculous I don't think anyone has even thought about attempting it.
That may translate to aliens. Although they would have mental abilities beyond certain threshold, they would be way more different to us than any Earth animal. The way the difference will manifest cannot be anticipated. Their modes of communication may be completely distinct from ours. I'm thinking “telepathic” as a way to illustrate what one mean by big difference. Say, they run into Voyager's records, and they don't have vision (or vision like ours), they may never guess the indentations on the records are a message at all.
You radio them. So they will recognize math, they will probably be observe your signal contains prime number sequence in binary. They may be still completely oblivious to anything that follows, or you – to their response.
Math really isn't a Universal language due to the fact that alien species might translates a math differently. Advanced species wouldn't even our modern day math as it would be severely outdated.
An alien really wouldn't understand what 1 + 1 meant because they would have no idea what 1 represented. Besides, if the alien didn't breathe oxygen, the BPM would be completely different based on how the alien life collected and used the non-oxygen gas. which would throw any mathematic similarities off.
But broadcasting a signal that is based on the heart beat of an animal, lets say an Eagle, however, would register as a foundation of similarity because the heartbeat of the Eagle on Earth would match the heart beat of a similar animal that flies, has a tolerance for cold weather and is able to survive at very high attitudes where other birds wouldn't be able to.
Once the heart beat of the Eagle had been decoded, the aliens would understand the concept of human time based on the algorithm of the heart beat of the Eagle.
Remember a body at rest will stay are rest and not consume as much energy while a body in motion will consume more energy. Thus the more at rest based on the animal the BPM per minute will be less. The more that the animal is active, the BPM will be more per minute.
Here are the heart beats of some animals
https://dinoanimals.com/animals/heart-rates-of-animals-top-10/
Hibernating Groundhog - 5
Blue Whale - 8-10 (slow moving through the water, has to constantly move, doesn't need quick bursts of speed, lower BPM)
Tortoise -10 (slow moving on the land, doesn't need quick bursts of speed, lower BPM)
Alligator- 32 (very fast in the water, needs a lot of oxygen pumping through its body at any time for quick and explosive attacks with its mouth or for running after prey.)
Elephant - 25-35
Horse - 28 -40
Dolphins - 35-45
Bear-55 (14 during hibernation)
Ox - 36-60
Condor -65
Human - 60 - 80
Large Dog - 60-80
Goat 70-80
Sheep 70-80
Medium Dog 80-100
Pig 70-120
Cat 120-140
Small Dog 100-160
Pigeon 185
Wild Duck 193
Parrot 200
Domestic Duck 240
Rhesus Monkey 160-330
Guinea Pig 200-300
Adult Chicken 250-300
Buzzard 300
Hen 312
Rabbit 180-350
Crow 378
Rat 250-400
Chick 350-450
Hamster 300-600
Mouse 450-750
Canary 1,020
Blue-throated Hummingbird 1,260
Etruscan shrew 1,511
Transmitting the signal
The BPM would be first, (then a silhouette representation of the animal), similar to how the U.S. Navy used silhouettes during WWII to identify sea based war vessels then a representation for ((air, land or water would)) follow. The primary environment that the animal would be found in would be first, then followed by the second and then third most frequented environment of natural habitation or where the animal spends 75%, 20% and 5% of its time. Natural means that the animal can exist in an environment without any means of artificially augments, such as a human being able to be in the air but not without being in an airplane. Land would always be first, then water then air.
Animals would be grouped together as follows, the smallest animal first to the largest.
1,511(Estruscan Shrew) ((land)), 450-750 (Mouse) ((land)), 250-400 (Rat) ((land, water))
120-140(Cat)((Land,water)), 100-160(Small Dog)((Land,Water)),80-100 (Medium Dog)((Land,Water)),60-80(Large Dog)((Land, Water)), 60-80(Human)((land,water))
Classifying signals of animals using a heart beat pattern along with pictorial representations of the animal based on the smallest to the largest animal plus a pictorial representation of the environment that the animals live in, would be easier to understand compared to sending languages that would take hundreds of years if not thousands to decipher.
When the aliens begin to see the patterns in the message, they will able to associate animals on their planet with animals that they are receiving from the alien world sending them.
Receiving an eagle signal from an alien world would definitely cause a great commotion in the alien species that would keep them interested in future signals instead of discounting the signal as just another FRB.
