There Are Thousands of Alien Empires in The Milky Way by Kurzgesagt – In a Nutshell - Reaction

Kurzgesagt – In a Nutshell

[BahamutZerodragon]

honestly i'd love to see more reactions to Kurzgesagt videos.

[mordreek]

He's basically describing a lot of the issues that pre HBG civs faced in Battletech, the sheer distances involved and lack of rapid coms meant you had a loong time for things to get hinky on the borders.

[arnabbiswasalsodeep]

More kurzgesagt reactions please! Sseth to this would be quite the journey

Dude old man MUST watch how to wage an interstellar war by this channel who’s name I will never be able to spell.

The speed of light is... rather difficult to achieve, at least as far as what we can currently do. So I think the "space is vast" bit is still a problem. That said, it's definitely possible that you're right.
My favorite thing is the thought that instead of what he said, "the human race is extremely young" maybe we aren't. Maybe we're the first species in the Milk Way to have evolved this much. We might be very old instead, comparatively. Unlikely, but possible. Fun to think about either way.

[rmartinson]

The thing everyone forgets about the likelihood of alien life is that while yes, the universe is utterly enormous to the point that life somewhere out there is basically a statistical certainty, intelligence isn't guaranteed just because there's life. On Earth, we have maybe two or three actually sapient species (though we're only truly certain about one) and a dozen or so near-sentient ones. That's out of literally billions of species that exist today or have ever existed on Earth, and the overwhelming majority of them are physically incapable of using complex tools due to their physiology, meaning they can never develop a civilization.

And while we can't be sure whether or not there was sapient life on Earth before the rise of the hominids, we CAN be sure that they never achieved our level of technology due to the lack of telltale traces such technology leaves behind in the geological record. Even if humanity died today, the chemical and radiological residue of our civilization's existence will still be visible in the geologic record a billion years from now. The fact that there is no such chemical trace of any prior species on Earth means that no hypothetical Earthly civilization before us made it much past the medieval level of technology before dying out.

So now extrapolate that out into space. In 3 billion years of playing host to life, Earth has produced exactly one advanced civilization, and that has arisen only in the last 10, 000 or so years, or about (or about 1/300, 000th) of the time that life has existed on the planet. The galaxy could be full of millions of life-bearing worlds, but that doesn't guarantee that any of them would ever produce intelligent life, or that any intelligent life they produced would be physically capable of using tools to build technology, or that any intelligent tool-users they produce wouldn't be killed off long before the point of developing civilization (much like what almost happened to humanity in the distant past, where geneticists have confirmed that our entire species once died out to the point of numbering only about 1, 200 humans on the entire planet), or that they wouldn't die out early on in the development of civilization due to plague, natural disaster, war, etc., or that they wouldn't achieve a high level of technology only to destroy themselves before they could spread to the stars. There are a shocking number of hurdles that must be overcome to get a truly advanced civilization. We have overcome most of them, but there were never any guarantees that we would.

So if life-bearing worlds are as rare as the video suggests, how rare then would intelligent life on those worlds be? How rare would intelligent life physically capable of civilization-building be? How rare would intelligent life that actually built a civilization be? How rare would a civilization that survived to the point of being capable of space travel be? How long can a space-faring civilization survive? And that doesn't even touch on the questions like "What if these other civilizations that beat the odds got started millions of years ago and are all dead now? Or what if they won't reach that point until millions of years in the future?" When you factor in all these hurdles to the existence of intelligent civilizations, it becomes clear that we very well might be the only civilization currently existing in our galaxy. We could be utterly alone with the galaxy as our island, with nothing but the ruins of the long dead and the primitive ancestors of the up-and-coming to keep us company.

Quite enjoyed this video, it's cool that you enjoy space and hypotheticals, as do I. Would love to see more reactions from kurzgesagt. I love Warhammer 40k, but I find it just as interesting, our real world science and what we can theorize about.

[ReinaSaurus]

the strange alien lifeform known as cat demands your submission, human. surrender to her mighty presence.

DONT PANIC, states "The Hitchhiker's Guide to the Galaxy" by Douglas Adams (RIP). kurzgesagt has the same animation style (and maybe even voiceactor) like the movie that was made for it (the explainatory clips inside of it).

[Soulwrite]

Fermi paradox assumes that the Drake equation is somewhat correct and isn't out by a factor of a billion or order magnitude more again.
We are doing guesswork with a sample size of one. That it is called a paradox is laughable, and it should just mean our inputs or assumptions were wrong.

[nialpollitt]

The Fermi paradox is based on the assumption that our Governments and institutions wouldn't lie about receiving signals from other civilizations.

[Writer-Two]

Oh, I watched this earlier today. Kurzgesagt is an awesome channel that is very fun to watch!

[vladyvhv]

If you haven't seen it, the black hole bomb is an epic one from their channel. But really, it's hard to go wrong with any of their stuff. As for the Dark Forest theory, I have to mention the less scary variant, where everyone out there just all subscribes to the Dark Forest idea, thus no one ventures out into it.

[jtfbreedlove]

Giraffes, I've heard there literally from another dimension. There's also this story out there called "their made of meat(?)" that posits the aliens ignore us because of all the "cool" species are either machines or energy.

[blazermettro]

You should react to more of their stuff. Its so fun.

[matthewdougherty]

old man 7:00 and the other thing most people don't think about is the other types of life that could have evolved using other mediums in place of water/h2o like a planet where the "water" is liquid gas or something like liquid Iron🤔 just something truly Alien

[kcdawnte]

Good book that looks into this idea of difference in communication and technology, Children of Time is great.

[lopful]

I always liked the theory that we are treated like a zoo or test by alien species anyway you should check out "Did The Future Already Happen? - The Paradox of Time"

[rumigraciea]

There is also the fact colonizing remote itself too costly it is more practical to create artificial colony ala gundam wing.

[AnotherCrazyClown]

I have an almost divine faith that we will find a way to achieve easy travel across the universe but i don't know how much time we would have to wait but i just feel that uncovering the secrets of the universe is the fate of humanity

[jessetorres]

My personal theory is that intelligent alien life does exist in the universe, but humans are the most technologically advanced which is why we've never made contact with any of them. It would be like someone traveling back in time then trying to call Alexander Graham Bell with their cellphone; the technology is similar but too advanced to communicate.
