Where are all the aliens? The universe is too big and too old, why have we not met aliens yet? Do they live in computers? Were they wiped out by an ancient super intelligence? Or are we just to primitive to understand their motives? Whatever the answer is, it is incredibly important for our own future.
First Fermi Video:
What is life:
Videos, explaining things. Like evolution, time, space, global energy or our existence in this strange universe.
We are a team of designers, journalists and musicians who want to make science look beautiful. Because it is beautiful.

Fermi Paradox II – Solutions and Ideas

Scientists involved in SETI research would factor this in. However, we wouldn't know when potential aliens might have sent any signal till we receive it. This is one of the largest obstacles we need to overcome somehow.
It might be possible for a civilization to develop Interstellar travel with outdated technology and a large amount of fuel?
Nuclear purpulsion or thermal electric pulsed purpulsion of some kind? Why not use Oil or Jet fuel to dissipate heat around the hull of an aircraft. Electric jet engines or small wings similar to tail fins on a rocket?
i think this theory is somehow wrong. i mean communicatioj with other civilizations isn't impossible. i mean look at us, humans. japanese language is so different from english or greek and communication before some years was impossible. but still we managed to communicate. today everyone can learn every language in the world. and we managed to learn ancinet languages such as ancient greek ancient Egyptian language etc. yet we can not talk with other species such us cats or dogs BUT we can understand them and help them and they can also understand us and help us. we know when dog is feeling sad or happy and when cat needs to eat or needs to play. communication between other civilizations out in space is not impossible.
For a space ship traveling with nearly the speed of light, it wouldn’t last long to get across the milky way due to the time delation from the theory of relativity! Only for the people, who stayed in their frame of reference it would have lasted 200,000 years!
"If there is a civilization out there that wants to eliminate other species, it's far more likely that it will be motivated by culture rathen than economics"
Why? That seems to me like the most baseless assumption I've ever heard.
This is literally the best channel on youtube. You should get millions invested into you and make videos for schools and unis that sum up everything we need to know in short entertaining and easily understandable videos. Would make the world such a better place. Keep up the good work i need more videos from u i too am an embryo that has a long way to go so teach meeeeeee 😂😂😂
There's a manga by Fujiko F. Fujio that depicts exactly that situation: aliens come to earth, hunting human to extinction, sticking them to sticks and roasting them to char for a baldness medicine, just like how humans treat many other species.
What about a 4D world, that would mean, that we cant see the aliens, just like a paper man couldnt see us, if we dont want him, but we can see him OK.
To be clear, I dont believe it, but i think it really easy could be like that....
What if there is a great filter ahead of where we are now, and once passed a species would be able to colonize its galaxy, but there is one after the next step and so it wipes them out after they have left our known universe. And so we cannot see them
Out of all our history only in the last 30 years we've begun pointing apocalyptic weapons to each other for political differences. I agree, we have much more problems to solve other than figuring out if there's other life in the universe. And if we are worthy enough of such knowledge.
Community pharmacists are the health professionals most accessible to the public. They supply medicines in accordance with a prescription or, when legally permitted, sell them without a prescription. In addition to ensuring an accurate supply of appropriate products, their professional activities also cover counselling of patients at the time of dispensing of prescription and non-prescription drugs, drug information to health professionals, patients and the general public, and participation in health-promotion programmes. They maintain links with other health professionals in primary health care.
