The universe is awash with strange radio signals, but astronomers have now detected a really bizarre one that repeats every hour, cycling through three different states. While they have some ideas about its origin it can’t be explained by our current understanding of physics.
Sorry but those are assumtions based on the idea that the earth is unique.
It is now estimated thatt trillions of plannests wxist in the milky way alone. And abiur 2 million galaxies in the observable universe. We have absolutly no idea how common ir complex the start of life is. Ands assuming we are in anyway unique is not a scientific answer with the knowlesge we have. It is just an assumption.
If life is common and we habe no way of knowing that is not the case. Then we also have ansolutly no way of knowing how common intelegence is.
If intelegence is common. It is reasonable to assume with time radio is an easy invention. Cos lets face it. Based on our data the least intelegent civilization we know off. And the most intelegent discovered it withing 5k years of discovering what we call civalusation.
So again the idea that it is complex for a life to evolve and develop radio is nothing but an assumption. Admitadly a common one. But not one based on any evidence at all. Instead one that is common mainly due to arrogance of mankind assumeing earth must be unique. Just because we lack the tech to see any others.
As for the odds of us developing in time to hear others. Again. The number of plannets and variaty of distances throw that argumebt in the trash.
The estimated number is so great. That no matter when i. The last *estimated" 13.7 billion years we look at. Odd ate high that nillions of planetz exist at the correct distance for us to hear them at some point in the last 100 years of radio until we die as a race.
Again i want to repeat. I am not saying this is such. I have no idea.so to say it is woild be absurdly arragant. And i am far to pessimistic to think such will happen in my lifetime.
I am only sayiing when you remove the (scientifically unviable based on current knowledge) idea that the earth is unique for some reason. Abd add it to the evidence we have found of how many potential planets are in the universe.
Occams Razer is in no way valid to assume it cannot or is provably not alians.
