Adam Frank Studies Alien Worlds To Find Earth’s Fate
What life is out there in the universe cheap designer bags replica beyond our planet, and how long can we sustain life on Earth? These are the two big questions at the center of astrophysicist Adam Frank’s new book. It’s called “Light Of The Stars: Alien Worlds And The Fate Of The Earth.” So, Adam, we got a two hour show here plenty of time bag replica high quality to cover what? all known and unknown universes.
ADAM FRANK, BYLINE: (Laughter).
aaa replica designer handbags KELLY: There we go. Let me start with this number that I best replica designer read and then went back and reread to see replica bags buy online if I had gotten it right. You say that the odds that we, meaning Earthlings that we are all alone and always were you put those odds at 1 in 10 billion trillion, meaning you’re pretty darn persuaded that there have been other civilizations out there. aaa replica designer handbags
Handbags Replica FRANK: Well, so, you know, even 30 years ago, we did not know whether there were any planets around any other stars in the universe. And of course we believe that planets high end replica bags are, you know, the first essential step to getting life and civilizations. But in the last 20 years, we’ve undergone this amazing revolution in astronomy where we now know that every star you see in the designer replica luggage sky has planets going around it and that, you know, if you count up high quality designer replica five of them, one of them has a planet buy replica bags online in the right place for life to form. Handbags Replica
KnockOff Handbags So when you add up all the possibilities in the universe, you end up with 10 billion trillion planets where a civilization could have formed. So that’s a lot replica bags of experiments that the universe has been able to run. And the idea 7a replica bags wholesale that none of them except ours went all the way to developing a civilization, you know, kind of strains it a bit. So that’s why I think that, you know, we are not unless the universe is really biased against it, what’s happening here has happened before. KnockOff Handbags
Replica Handbags KELLY: If you’re right and what’s happening here has happened before or is happening right now somewhere in a galaxy far, far away. What can life on other worlds tell us about our own fate? Replica Handbags
cheap replica handbags FRANK: Well, this really relates to climate change and then what this new era that we’ve pushed the Earth into that people call the Anthropocene, the human dominated era. And so, you know, as obviously this is a point of contention in politics, a lot about the debate. But in science, you know, we’ve known for quite a while that we’ve been changing the planet. cheap replica handbags
Wholesale Replica Bags And from this perspective, what you realize if you see that there has best replica bags online been many other civilization; we’re not the first, all of them probably push their best replica bags planets into some era of climate change, that it’s almost inevitable if you build a world girdling civilization that’s sucking up a huge amount of energy that they best replica designer bags will all push their planets into climate change. And then the question is, does anybody make it? Does anybody make it to sustainability? Wholesale Replica Bags
wholesale replica designer handbags KELLY: Right. The idea as you put replica designer bags wholesale it is basically that if there have been advanced societies out replica bags from china there that have developed, that they would be changing their climates and perhaps have self destructed. wholesale replica designer handbags
high quality replica handbags FRANK: Well, that’s the question. So, you know, one of for me, this perspective, what I call the astrobiological perspective. We often think we have to, you know, sort of prove to people that we you know, that we’ve triggered climate change. From this perspective, the that question doesn’t even really exist. It’s, of course we triggered it. Any civilization that, you know, emerges a technological civilization that emerges on a planet is really a mechanism for harvesting energy and doing something interesting with it right? building your civilization, buildings, whatever. And what we really find from replica bags china when you consider that is that there’s no way for the planet not to respond. high quality replica handbags
So on Earth, we are consuming almost a quarter of the total power that the entire biosphere, the entire collection of life all the trees and microbes we consume a quarter of that. How could there not be an effect, right? How could the planet not notice that we’re there? So then the question becomes, can anybody make it to sustainability? Can any civilization navigate its transition its climate change transition and make high replica bags it through to the other side where you have a long term relationship with the planet and you’re not wiped out?
KELLY: So this is in a way, I mean, it sounds totally terrifying to think that maybe other societies have been out there, been through this, and we don’t know about them because they managed to exterminate themselves. On the other hand, this is a comforting message maybe right? that we don’t need to have quite the angst about climate change as a political issue because this is completely to have been expected. And the challenge now is, all right, what do we do going forward?
FRANK: Absolutely. I think that’s part of the way this perspective really changes the story we tell. What I like to say is that you can’t solve a problem until you understand it, and you can’t understand it until you know how to tell its story. And when it comes to climate change, we’ve been telling the wrong story. And part of that story is that we stink, right? Human beings are a plague on the planet.
replica handbags china FRANK: We’re horrible. We’re greedy. And look; God knows human beings can do horrible things. But in this respect, buy replica bags triggering climate change was not our fault, right? We’ve been using energy since for high quality replica bags 10,000 years in any form we could find animal dung, animals themselves to power civilization. And when we discovered oil, it’s not like we, you know, twirled our mustaches and replica bags online said, mwahahaha (ph), I will destroy the planet. Instead we used it to do amazing things heating homes, you know, making internal combustion engines. replica handbags china
Replica Designer Handbags So triggering climate change was not our fault, but not doing something about it now that we’ve recognized it, not switching energy infrastructures now that we’ve recognized it yeah, not only would that be our fault, but it would be our folly because what it would mean is is that that would be the reason why we didn’t make it across the other side. Some civilizations make it, and some don’t. And that would be the reason why we wouldn’t make it. Replica Designer Handbags
Designer Fake Bags KELLY: But again, is all replica designer backpacks of this completely hypothetical? I mean, we have. Designer Fake Bags
Replica Bags FRANK: Part of this revolution in astrobiology and thinking about life and planets together, which high quality replica handbags we only are just learning how to do, is to look at the history of the Earth, right? The Earth is 4.5 billion years old. There’s been life on it for at least, you know, around 4 billion or so. Replica Bags
And the Earth has been many different planets, right? There for a while, the Earth was a waterworld. There weren’t any continents on there. And there’s been times when the Earth has been a snowball world almost entirely encased in ice. It’s been a jungle planet. There was a time when there was no oxygen in the atmosphere, a long period even when there was life. And it was life itself, microbes that through their you know, their own living processes made the atmosphere oxygen rich. And we wouldn’t be there without that. All of those have lessons for us about how we have to reintegrate ourselves as part of the biosphere.
Fake Designer Bags We sort of we’ve sort of grown up thinking that we’re different from the biosphere, and the lesson of this long view, including thinking about possible other civilizations, is that any civilization that makes it has to reintegrate itself back into the biosphere. You can’t just push the biosphere around and expect it’s not going to feed back on you. Fake Designer Bags
Replica Bags Wholesale So the real perspective that we gain is we are what the biosphere is doing now just as, like, on other planets that have grown civilizations, that will be what their biospheres were doing. replica designer bags Just like on our planet, you know, there was grasslands, that was the experiment the biosphere was running a while ago. Dinosaurs were an experiment the biosphere was running a long time ago. We’re good quality replica bags what the biosphere is doing now, but it doesn’t mean we’re what the biosphere is going to be doing 10,000 years from now. https://www.i-eluxuryhandbags.com Replica Bags Wholesale
