Michio Kaku: Let’s not advertise our existence to aliens
The countdown continues! The 4th most popular video from 2018 involves humanity hiding behind a tree.
Michio Kaku is a futurist, popularizer of science, and theoretical physicist, as well as a bestselling author and the host of two radio programs. He is the co-founder of string field theory (a branch of string theory), and continues Einstein’s search to unite the four fundamental forces of nature into one unified theory. He holds the Henry Semat Chair and Professorship in theoretical physics and a joint appointment at City College of New York and the Graduate Center of C.U.N.Y. He is also a visiting professor at the Institute for Advanced Study in Princeton and is a Fellow of the American Physical Society.
Kaku launched his Big Think blog, "Dr. Kaku's Universe," in March 2010.
MICHIO KAKU: We have this mental image that a flying saucer will circle the White House lawn, land on the White House lawn and give us a bounty of all sorts of technological goodies to initiate an age of Aquarius on the planet earth. Personally, I don't think that's going to happen. For example, if you're in the forest do you go out and talk to the squirrels and the deer? Maybe you do for a while, but after a while, you get bored because they don't talk back to you because they have nothing interesting to tell you because they can't relate to our values and our ideas. If you go down to an anthill do you go down to the ants and say I bring you trinkets; I bring you bees; take me to your aunt queen; I give you nuclear energy. So I think for the most part the aliens are probably not going to be interested in us because we're so arrogant to believe that we have something to offer them. Realize that they could be thousands, maybe millions of years ahead of us in technology and they may have no interest in interacting with us in the same way that we don't necessarily want to deal with the squirrels and the deer in the forest.
Now some people say that we should not try to make contact with them because they could be potentially dangerous. For the most part, I think they're going to be peaceful because they'll be thousands of years ahead of us, but we cannot take the chance. So I personally believe that we should not try to advertise our existence to alien life in outer space because of the fact that we don't know their intentions.
Then the other question is what happens if they're evil? Well, I think the question of evil is actually a relative question because the real danger to a deer in the forest is not the hunter with a gigantic rifle; he's not the main danger to a deer in the forest. The main danger to a deer in the forest is the developer; the guy with blueprints; the guy in a three-piece suit; the guy with a slide rule and calculator; the guy that's going to pave the forest and perhaps destroy whole ecosystems.
In other words, the aliens don't have to be evil in order to be dangerous to us, they might not care, they just might not care about us and in the process pave us over. In fact, if you read the novel War of the Worlds the Martians in HG Wells seminal novel were not evil in the sense they wanted to torture us and they wanted to do all sorts of barbaric things to humanity. No, we were just in the way. And so I think that is a potential problem. We could be in the way of a very advanced civilization that simply is not evil but simply views us as we would view squirrels and deer in the forest. So personally I think that we should not advertise our existence when we go into outer space. For the most part, however, I do think they are going to be peaceful, they're not going to want to plunder the earth because there are plenty of planets out there that have nobody on them that they can plunder at will without having to worry about restive natives called humanity. And so I think they're not going to come to visit the earth to plunder us, to do all sorts of mischief. For the most part, I think they'll just leave us alone.
- If advanced alien civilizations do exist, theoretical physicist Michio Kaku asks: Why would they want anything to do with us? It would be like an academic talking to a squirrel, he suggests, and he has a great point.
- Hollywood and science fiction novels have conditioned us for years to believe that aliens either want to hang out on our intellectual level and learn from us... or destroy us. If alien life really does have the technology and know-how to make it all the way here, perhaps we should just play it cool and not assume that we are the top species in the universe.
- Kaku speculates that our hypothetical demise would come at the hands of an intelligence civilization that sees us as no more than deer in the woods and wipes us out by accident — just as we have done to (what we deem) less remarkable species since time immemorial. Our best bet for survival? Lie low.
The 21st century is experiencing an Asianization of politics, business, and culture.
- Our theories about the world, even about history or the geopolitics of the present, tend to be shaped by Anglo perspectives of the Western industrial democracies, particularly those in the United States and the United Kingdom.
- The West, however, is not united. Canada, for instance, acts in many ways that are not in line with American or British policies, particularly in regard to populism. Even if it were united, though, it would not represent most of the world's population.
- European ideas, such as parliamentary democracy and civil service, spread across the world in the 19th century. In the 20th century, American values such as entrepreneurialism went global. In the 21st century, however, what we're seeing now is an Asianization — an Asian confidence that they can determine their own political systems, their own models, and adapt to their own circumstances.
Research has shown that men today have less testosterone than they used to. What's happening?
- Several studies have confirmed that testosterone counts in men are lower than what they used to be just a few decades ago.
- While most men still have perfectly healthy testosterone levels, its reduction puts men at risk for many negative health outcomes.
- The cause of this drop in testosterone isn't entirely clear, but evidence suggests that it is a multifaceted result of modern, industrialized life.
Can sensitive coral reefs survive another human generation?
- Coral reefs may not be able to survive another human decade because of the environmental stress we have placed on them, says author David Wallace-Wells. He posits that without meaningful changes to policies, the trend of them dying out, even in light of recent advances, will continue.
- The World Wildlife Fund says that 60 percent of all vertebrate mammals have died since just 1970. On top of this, recent studies suggest that insect populations may have fallen by as much as 75 percent over the last few decades.
- If it were not for our oceans, the planet would probably be already several degrees warmer than it is today due to the emissions we've expelled into the atmosphere.
