Want to get someone to like you – or like you more? If so, there is a simple thing you can do that can work wonders to improve your likeability. This episode begins with this simple technique. https://www.psychologytoday.com/us/blog/let-their-words-do-the-talking/201608/people-will-you-if-you-make-them-laugh Why are we here? You must have thought about this question. I mean, here we are, intelligent creatures hurtling through the universe on this tiny little planet. Why? What’s the point of it all? What had to happen for us to be here? These are questions that science has struggled with but is now finding more and more insight into the real reasons we exist. Here to reveal what we do know is Tim Coulson, a professor of zoology at Oxford University whose teaching and research have earned him multiple awards. He is author of the book The Science of Why We Exist: A History of the Universe from the Big Bang to Consciousness (https://amzn.to/4jLgb0n). There is a growing type of relationship that doesn’t even have a proper name. It’s 2 people in a partnership and they are not romantically connected but they are more than friends. They are more than best friends. They often live together, are in each other’s wills, travel together and essentially live as partners. How do these partnerships begin? Who are the people in them? Why is this a growing arrangement? The first person to really look at this is my guest, Rhaina Cohen. She is an award-winning producer and editor for NPR’s documentary podcast, Embedded and her writing has appeared in The Atlantic, The Washington Post, The New Republic and elsewhere. She is author of the book The Other Significant Other (https://amzn.to/42unjsn). You probably have no idea what all is involved when you sneeze. It’s really quite something! And it involves a lot of different muscles to make it happen. Listen and you will learn things about why and how you sneeze and when you can and cannot sneeze. https://www.medicinenet.com/11_facts_about_sneezes_and_sneezing/article.htm Learn more about your ad choices.

Chapter 1: What simple technique increases likeability instantly?
Now, if you think about it, the universe is 13.8 billion years, so a couple of thousand years is but a blink of an eye. And so the likelihood of two intelligent civilizations being close enough to gather, close enough to one another in the vastness of the universe to communicate, is actually quite a small probability.
But despite that, we are going to keep listening out and we're going to keep listening to see whether there's any evidence of intelligent life. But what we might find is evidence of simpler life, say bacteria, living on other planets.
And there is even some space probes that have gone out to the moons of Jupiter and Saturn to look for evidence of bacterial lives on those moons, because what we do know is liquid water does exist on those moons.
When science looks out into the universe and sees that only life is here on Earth, do we get any sense as to why that is? I get that's the name of the book, but why are we here? I mean, I get how we're here. It's a pretty remarkable story how we got here, but what purpose do we serve? Are we part of this or are we an accident?
So I think the way that I would answer that question is probably in a couple of parts. And so we understand what had to happen for life to get started. And there are sort of three things that need to happen. Life is just very complicated chemistry and it's chemistry that can replicate. So it's chemistry that can make copies of itself.
And there are actually quite simple reactions that can make copies of themselves. They're called autocatalytic reactions. And so we think that life started off as an autocatalytic reaction that became more and more complicated. And we have some ideas why that might happen. The second thing that life needs to get going is energy.
And the very first life on Earth was almost certainly driven by volcanic energy. It's known as chemosynthesis. So it would have relied on highly reactive molecules that were created by volcanoes. And it used that to power its replication. And then the third thing it needs are membranes to sort of keep it all together, to keep the replicating molecules together.
And those are quite easy to form as well. So given that, we think that simple life probably gets going quite frequently within the universe. There are probably not every planet by any stretch of the imagination. But I think a lot of biologists and a lot of chemists now suspect that life gets going reasonably easily. And it got going quite quickly on Earth once conditions became suitable.
We had liquid water for that to happen. So we don't think the early Earth was so unusual that life would have got started only on this planet. We suspect it's quite commonplace. Now, if that's the case, the next question is, how long does it need to become complicated? And life has been evolving on Earth for about 4 billion years.

Chapter 2: What recent scientific discoveries explain why we exist?
You had said a few moments ago that, you know, we've only looked at a little bit of the universe and not found life anywhere else other than Earth. But if there is life, intelligent life out there that perhaps is more advanced than ours, why haven't they found us?
a good question and it boils down again to the size of the universe and the universe has a maximum speed limit and that's the speed of light and even in terms of light years so that's a distance that light travels in a single year the universe is absolutely vast it's um you know it it takes uh the sun is is our closest star obviously it takes eight minutes and 20 seconds
for light from the Sun to reach Earth. But if you're looking out to our nearest star system, even if you're travelling at the speed of light, it's going to take you about four and a half years to get there. Now, anything that weighs anything, so anything with mass, can't get anywhere near the speed of light. So, you know, it can only get to a fraction of the speed of light.
even if an intelligent uh species on another planet had heard us and set off it's going to take them you know decades if not hundreds or thousands of years to get here so it takes like 26 000 years to get to the center of our galaxy and that's moving at the the universe's speed limit so unless we can come up with ways of traveling around the universe perhaps you know through
Thinking about kind of Star Trek and kind of in science fiction here through worms hole it her wormholes in space it's going to be very difficult for organ it for Intelligent aliens and other planets to get here and we've only been sending out signals to them for 120 years which is when Marconi sent his first radio signal out so if they're listening to that and they were say there were 60 light years away They would have heard that
If they sent a signal back to us, we would only be receiving it about now. And they would have to be within 60 light years, so 60 to get to them and 60 to get a message back. And there's only about 3,000 stars within 60 light years of Earth, which is a tiny number compared to the stars in the universe.
So it's possible there's intelligent aliens making their way to us now, but they're probably not going to arrive for a while.
We're exploring those deep questions of why we exist. What are we doing here? My guest is Tim Coulson. He is a professor at Oxford University and he is author of the book, The Science of Why We Exist, A History of the Universe from the Big Bang to Consciousness.
We are Theresa and Nemo. And that's why we switched to Shopify.

Chapter 6: What are platonic partnerships and why are they increasing?
13.8 billion years ago when we were to do the experiment where we run the experiment forward we would find that we were here we were sat here today having this conversation that exactly the same things would happen and so they argue that what what they say is the the universe is deterministic and with a big enough computer we would be able to predict the behavior of every single tiny particle
in the universe and how they formed atoms and how they formed planets and how they formed us. And that if we ran the clock again, we would be here. There are other scientists that say, actually, no, I don't believe that. I think we've won the cosmic lottery. There've been a large number of events that had to happen for us to be here and they were chance events and they were truly chance events.
And then the question comes, The question that they then ask is what is luck and where does chance come from? And what's really interesting at the moment, the only true source of randomness, so where luck could come from in the universe, is the behavior of tiny particles. And that's known as quantum behavior or quantum mechanics.
And it's the fact that these tiny particles behave like waves as well as particles. And I won't go into, it's quite an abstract concept. It's a very powerful theory and it's almost certainly correct. And the question is, is how does that randomness at the very, very small scale of tiny particles
translate to random behavior such as an asteroid colliding with earth or even the evolution of consciousness because one of the really interesting things that comes about is if the universe is deterministic then free will is an illusion that doesn't sit well with me i don't believe that um that free will is an illusion i was it was inevitable that we'd be having this wonderful conversation now at the birth of the universe but but some scientists
believe that it's deterministic and with and for a reason known as something as quantum entanglement and quantum entanglement is something that we don't fully understand yet and i don't believe we've quite got the right interpretation of so you had mentioned at the beginning that that there is some evidence that perhaps or there's some reason to believe anyway that that intelligent life may have been around before elsewhere
Which implies, or I infer from that, that our intelligent life may someday just go away like it may have happened in the past.
Well, so a couple of answers to that. So first of all, there was another species, a cousin of ours. We shared a common ancestor, but it was a different branch of the tree of life called Neanderthals. Many people will have heard of them. And they lived in Europe up until about 40,000 years ago. And they had language. They had culture. They painted the first cave paintings.
So they buried their dead. So these were clearly another intelligent species on earth related to us, but not our direct ancestors or anything. So intelligent life, has evolved twice. They had brains that were about the same size as ours. Now, the second part of your question is what might happen to the earth in the future?
