Are Aliens Smarter Than Us? With Neil deGrasse Tyson and David Grinspoon

Can there be life on planets without magnetic fields? Neil deGrasse Tyson and comedian Chuck Nice discuss exoplanets, extraterrestrials, and answer extraordinary questions from our fans with astrobiologist, David Grinspoon.
Can we entertain the idea of non-carbon-based life? We explore why carbon works so well for the basis of life and whether silicon-based life seems possible. What chemistry is different between the two elements? Learn about agnostic biosignatures and what the basic definition of life is. Is chemistry the same everywhere?
Why do we assume that any life we find will be more advanced than us? What would we do if we discovered life less technologically advanced than us? We discuss the SETI protocol and the likelihood that we would be able to communicate with aliens once we found them. Why are there supermassive black holes at the center of galaxies? How did they get there? Could there be life on a planet without a magnetic field?
How many Earth-like planets do we know about that reside in habitable orbits? We get into the JWST’s contributions to exoplanetary discovery and whether it would be possible to achieve a fully scientifically literate population like in The Orville. What aspects of planets are scientists looking for in the search for life? How close to a planet do we have to be to confirm these attributes? Was Venus once a habitable planet? We talk about runaway greenhouse effects and whether Earth could ever become what Venus is now. And finally our most important question: does weed still work in space?

[@sailorgeer]

On the question in science fiction about encountering intelligent but less advanced civilizations, this theme comes up repeatedly in the Star Trek canon, where humans (and other advanced species) decided on a policy of non-intervention and non-contact with any civilization not capable of interstellar travel, aka The Prime Directive. Humans themselves were left to themselves until the the moment they developed faster-than-light travel, at which point the Vulcans initiated First Contact. There’s also the famous quote from Arthur C. Clarke, “Any sufficiently advanced technology is indistinguishable from magic.”

[@pjftoo7588]

Love the show guys. Always informative and provocative. The question of having a contact protocol, or protocols, for alien life brings up some serious moral questions that we must ask and answer first, IMO. I think that the whole issue may turn out to be much more complex than the cliché of a superior space faring civilization dropping by and asking us to take them to our leader. In that situation we certainly need some advance and agreed upon principles, but realistically, we would almost certainly have very little control over that situation. It is all the other possible subsets that may require some serious soul searching from humanity et al. If carbon/water based life is the only, or the most common, form in the universe, I suspect that we will encounter complex, possibly even intelligent, alien carbon based life in our own solar system long before contact with any extra solar civilization. Who is to say that moons with tidally heated sub surface oceans are not a more stable and more common location for carbon based life than, habitable zone, rocky, water/atmosphere planets, with long lasting magnetic fields, and stable suns, are. If that is the case, and we encounter a totally alien eco system, we will be on the other side of such contact protocols, and we will be judged by those choices. The question that I ask myself is in such a situation what would we do? Will we be cautious, respectful and altruistic towards this alien life or will we build some nice big habitats, and pillage local resources to support it, while we plan the full colonization, and possibly contaminate a fragile ecosystem with some new opportunistic organisms. What I hope we would do, and what I believe we would do, are two very different things, unfortunately. Another protocol question is if we do find even alien microbial life on a planet or moon in the solar system, do we have the right to interfere with even that simple life? Just because life on a body is simple at the moment does not mean that as conditions change over hundreds of millions of years or longer that the simple life may not evolve into a complex or even a sentient technological species. Who are we to make such decisions? Posit a hypothetical, compatible, space faring species landing here 3.4 billion years ago, looking around and saying, sweet, nothing here but these oxygen producing bacteria and we want that, lets move in. None of us would be reading this now. Personally I think the default position for contact with any less complex alien life discovered by us should be the LITFA protocol (Leave It The Fu** Alone).

[@Mahlak_Mriuani_Anatman]

I love LITFA, especially if we stumble upon super advance civilization, trying to pull a gangsta As the saying goes faq around and you'll find out Tho i doubt humans will survive 200 more years

[@jeremymoses7401]

I would think one of the biggest proponents of assuming they are more advanced than us is because we accept that when we view these far away places is that we are peering through the lens of time. We arent seeing the object as it is but as it was. So, to "see" a civilization on a far out planet in another galaxy, or even our own, it would have to have been there long enough to affect the light we are currently viewing. This adds to the complexity of the window with which we can visably detect. We may view a planet that appears devoid of life that is teaming with it because its fairly recent; or we may see an active civilisation.... which could actually be long gone.

[@krishnabhutada3983]

Fantastic episode,Greetings from India...Happy stargazing...Keep looking up!

[@randolphphillips3104]

Problem with finding NTIs is that until we can go there (or they come here), all we can do is listen. Imagine they are 500 light years away. They would have to been at a radio frequency capable tech level 500 years ago, and they will have had to send out a powerful enough signal that it doesn't blend into the background before it gets here. Even we are moving towarf low power and directional. Now add in the expansion of space. Gets geometrically harder as you think of and add new requirements. Hope they find one, but I doubt we are definitively detect except by from very close, so I would think NTIs would be the same.

[@Folkstone57]

And yet we can “fathom our universe” & what is your point about consciousness ? How do you know “….we just can’t understand…” consciousness or do you mean we don’t yet fully understand it ?

[@xPhen]

I disagree. The mind allows us to discover anything we put it to. Name one thing on this planet and its been named because we have discovered it. Once we understand something, it becomes facts in a systematic values and becomes tested repeatedly. Though we haven't discovered something doesn't mean we don't understand it. We are logical beings not reactive beings. IF we ant to know something we can learn it by asking the right questions and testing theories. We're fairly amazing beings.

[@Folkstone57]

@@xPhen And the even better news is we probably have a great deal more to discover & learn. For instance, the Big Bang model is supported by a great deal of evidence, yet we have not been able to observe the processes prior to the Planck time because we currently have no way to do that & it may be a limitation that cannot be overcome.

[@xPhen]

@@Folkstone57 Maybe. Or we know it all already and we just haven't wasted the time to turn theories into tests. Which become facts that value proof. That then turns into truth. So its purely the mentality we have approaching subjects or things we don't understand at this time. Its all out there its dependent on us finding it or allowing ourselves to discover without hiding out intentions. Like meditation, those who don't practice don't know the effects and never will without testing it for themselves.

[@Folkstone57]

@@xPhen I don’t think it’s even remotely possible that “…we know it all already….” as that flies in the face of human history. I’m not sure what you mean by facts becoming truth.

We really only know of one form of life, that being the cellular based life that we have here on this planet. If we did not have ourselves to observe, we would never be able to imagine our own form of life, the cell based variety. It seems really far beyond what our imaginations are capable of thinking of when we ask what types of life are possible other than our own cell based life. We could really be in for some big surprises someday when we run into life elsewhere.

(Currently dependent upon the results of my gravity test). d. "I" do not even actually exist but eternally existent space time exists as me, currently in the forms as above. * I exist and yet "I" simultaneously do not exist, dependent upon perspective. But yet, do "I" not truly exist in absolute truth reality as only eternally existent space time exists as all things in absolute truth reality? * "I" can mentally change between perspectives thereby experiencing existence from those various perspectives. "My" mind continues to expand, but is it truly 'my' mind that is expanding or is it eternally existent space time's mind that is expanding? In absolute truth reality, it would seem to be the later. * 'To Be or Not To Be'. I am both, 'I Am and I Am Not.' But I Am Not it appears more than I Am. * Consider also: If asked the general question, 'What do you know?'. My current answer would be, 'Not much compared to all that can be known.' (I Am Not, More than I Am). It's humbling.

When we think of the evolutionary development of advanced alien species we assume that they went through the phase we are at now. Thinking outside the box let’s consider that they may have skipped that stage and went on to super-intelligence instantly. Let’s also assume that they are a benevolent species. We can start there and then bring other evolutionary traits in to consideration to explain their development. Evolutionary development like ours probably is not the only way. But it is fun to consider all the different possibilities. I love how Neil, David and Chuck get me to think outside the box. Thanks guys.

To what degree is the oceans change to the moons position vs the atmosphere, does it change with its chemical composition? I was looking at how quartz watches work. With tesla's research lab at the base of pike's peak, and the pyramids, would that change change the voltage of piezoelectric crystal?

[@supercommie]

I personally think we should be systematically under-counting the number of earth-like planets in habitable zones because our solar system had 3. Mars, Venus and Earth. All of them had Oceans at different points, Mars lost it's atmosphere so it got too cold, and Venus had a runaway greenhouse effect happen.

Silicon does not seem to enjoy remaining as a complete unit for very long. It breaks down and degrades rather fast when compared to carbon. ESPECIALLY when exposed to sunlight and oxygen. There are carbon based objects that are thousands of years old, surviving to this day. Meanwhile, everything silicon based has and will continue to degrade and essentially fall apart. I can not see silicon as a base for what we currently consider to be life. But again, I am basing that off of what humans have done with silicon so far. Perhaps nature knows a way to combine silicon molecules to extend usable existence.
