A wonderfully easy and thoroughly engaging talk to listen to, even for those of us who may already be familiar with the examples shown here. I am consistently proud of the Royal Institution for showcasing scientific communication to the world.
Do you do any of the space projects on Zooniverse? there's a good community of people of all skill levels there. I have a current potential giant planet orbiting a low-mass star and supernova candidates and I've never owned a telescope.
How wonderful that the universe very occasionally creates by a series of accidents, a gifted science communicator able to deliver these staggering concepts on mainstream media and in RI talks. Thank you
Thankyou Chris, I loved your presentation and your dry wit , especially the Just Wonderful Space Telescope 😂😂…it is quite humbling to realise how accidental some major advances in understanding have been
16:40 - pondering 'answers' to the Fermi Paradox is one of my favourite intellectual activities. It touches upon such deep questions....how we view ourselves, how we view humanity and our trajectory as a species.... what we suspect is the nature of the cosmos in relation to fostering life ... whether one thinks that consciousness, that strange and mysterious seeming trick of advanced life, whether THAT is in some way central to the cosmos .... what we think of time, etc, etc. The Fermi Paradox is a fun question to engage with.
Go fry a chicken o darn it , I'm cloaked in gravy balls for a couple hours but a lot more with me now and I have to deal of to listed above all that we will be a little concerned to ensure we are going ahead to make sure my work got finished by end up in a couple weeks and a little bit of the app to get the chance of a joke or not so confident in that now that you have a better understanding of the process and how to make this change but I will request that myself to say it last week because it still has me angry and I had been told by my manager that this information would be forwarded on to me for the past year was the best I could for the company after certain people had retired but I was wondering what the best I can see you in this regard as I'm a fan
That is so cool, and I'm jealous in the most spiritual, mental and psychological way, plus I was personally enriched by their free to learn class on chemistry, so I'm happy for you in the most altruistic way simultaneously grateful for the Institutes philanthropic endeavors!
I read the answer to the Fermi paradox just recently from a humble TH-cam comment and I wish I could remember the name of the person that presented the solution. There is no Fermi paradox, life is out there, but the reason we don't know about them is because like us, they simply cannot get government funding to progress their civilisation.
Ummm....Yeahh....No. Just...No. You're honestly trying to say that there's all these advanced lifeforms just like us out there... but tragically, they just can't procure funding from their governments to come find us??🤔🤦🏼♂️
Soon, they are working on that tech I'm sure. We just don't know about it yet. Look what we have done in just the last 15 years! Won't happen in my lifetime, but we will get there. Maybe even in a tourist capacity!
Neil de Grasse Thyson summed it up nicely on a Star Talk dissussion recently when he explained that most sicentific discoveries are preceded by the statement: "ooooh, that's weird"
Honestly, it is precisely counterintuitive to focus the Hubble telescope at nothing in order to discover what is actually there and 100% new but a perfect example of thinking outside the box...like the double slit experiment changed by the observer which honestly is counterintuitive until you consider the observer needs to convert and capture light for the observers ability to report on what they observed!
There is no paradox in the search for life. The only paradox's are those that are invented. If we search with an open mind then we will find whatever we encounter.
The odds of finding and understanding something completely different are small. Even different human civilizations are so different that it is difficult, and the number of possibilities mean that our sun will burn out first
When I think about the origins of life on earth I assume that a certain set of special conditions existed on the planet for limited period of time, and could not have taken hold any earlier or any later, but I don’t know exactly what those conditions were. What I do know is that in our 4.3 billion history, this happened exactly one time. That fact leads me to believe that life is extremely rare in the universe and is therefore more precious than we know.
Wouldn't it be amazing to have a 'POV' view of an ultra-sturdy melting-swimming probe as it descended through the icy layer of a moon and into its ultra-deep ocean. It would be so fascinating ... would we see anything macroscopic life? Would ANYTHING live? It's so hard to imagine vast amounts of water and NOT imagine life, but that's due to our Earth-centric view where every where we find liquid water, we find life. I'd LOVE to have these outer moons explored ....
I love the story behind the The Hubble Deep Field image and I have the Hubble _Ultra_ Deep Field taken over 11.3 days total exposure between September 2003 and January 2004 as the background for my computer monitors. I do wonder what the - carefully unnamed - _Eminent Astronomers_ who said there'd be nothing there thought on first seeing the images. 🤣
I cant remember who said it originally, but once I heard it, it became my goto way of explaining how science usually works: Scientific discoveries are rarely made with a cry of "Eureka!" But most often with a mutter of "Hmm, that's interesting..." The discovery of Uranus being one such example, someone looked at the orbit of Saturn, realised there was an anomaly and said "That’s interesting..." and that lead to the discovery of a new planet.
11:57 - "an underwater ocean" - now that's something I have never heard before! Other than that - a brilliant lecture. (But my niggle does show that I was paying attention!)
When you think about it, every ocean is >99% underwater. I think he meant "underice", but that didn't sound like a real word, so his mouth replaced it with "underwater".
Is it possible that we don't see signals bouncing around the cosmos, because of the distance other exoplanets are away, as an example just say we were trying to send a signal to a planet revolving around a star in a distant galaxy, we could track the planet, and make adjustments for how long it would take the signal to get there. But even then if the planet we are targeting is the same size as earth, how would we know where on the planet to aim the signal to the receiving antenna. Even if we did know exactly where the rx antenna was, the chances landing that signal on that antenna would be infinitesimally low, any signal that landed would be unexpected/fleeting and written of as an fluke which is an accurate description of what it would be.
You know, even the info concerning penguin poo is a valuable serendipitous knowledge that plausibly lends itself to alien detection especially when one considers that everything alive with exception to the human face mites, does in fact poo!
One of the problems of our 'understanding' of astronomy is that we use earthbound measures. 4.5 billion years is only 'a long time' is you're a human and use a time scale that is designed by and for humans. If you were simply to recalculate everything using an equivalent Neptune-based set of measurements where 1 year is 164.8 earth years long, the whole situation would look completely different.
It's not a problem of understanding. You and I have an idea of what 4.5 billion years is because we know what our Earth year feels like. And we are numerate.
55:45 f _They argued if the distant universe was like what we see around us, then Hubble would discover no new galaxies._ I don't understand this argument. If I stand midst of a forest which is not too dense but with roughly equally distributed trees, any gap between trees will reveal other trees behind it, shouldn't it? If there is a gap and I don't see any trees through it, this means that the region I'm looking at is not the forest any more, NOT something similar to my vicinity.
I think they have a lot of Crystals which could be used in higher frequency settings and the lowers ones as well that becomes a Tallow flow without destruction of itself in a way we can find out how much they can transmit and resonates with other ones atoms heat up or freeze in place for a long term relationship of resonance. Imagine that all vibrations are stronger or weaker in certain areas and the floating density is measured as a different environment than the same planet or moons in each state of gravity recordings in crystal caverns or surface space that was in a very distant way
Little correction: Cassini wasn't launched from the Space Shuttle (anymore). It was launched (fittiingly) on a Titan rocket. The concept of launching probes and satellites with the Shuttle died with Challenger. Sadly not before seriously crippling Galileo. Doing a "mundane" transport job that could be done with a much, MUCH cheaper rocket, saved costs and pointless risk for astronauts.
@@mpmpm read and understand.... Launching a satellite or probe with he Space Shuttle is a pointless risk for astronauts, because it is not science! It's a transport job. And doing it with the Shuttle has absolutely NO benefits over doing it with a rocket. So putting multiple people at risk for that makes no sense. Hence "pointless". And as i said it was also insanely expensive compared to a rocket. So you have high costs, risking a whole crew for a needlessly complicated launch job, for no benefit. It was stupid and after challenger the Shuttle was reserved for actual science work, deemed worth the risk. The Shuttle is worth reading (or watching) up about. It was the result of budget cuts ,politics and design by many committees, making it much less than it could have been. Why Nasa missions and even commercial satellites were launched on it was also political. It's history is complicated. And interesting. And to explain the Galileo thing (years before Cassini) : it was supposed to launch on a Shuttle. But after Challenger, the Shuttle was grounded for 2 years and Galileo put in storage. It is likely that the greasing of various bearings suffered from that and that's why Galileos big main antenna never unfolded. Limiting it to a few low bandwidth engineering antenna to send data back. Despite some engineering magic by Nasa it limited Galleos bandwidth for the entire mission. Lessons for Cassini, directly from Galileo: Fixed main antenna, no fancy unfolding business, and DON'T launch it on the Shuttle. Making Cassini a unqualified success.
Im soooo sick of the media printing headlines that arent true or suggests ideas that havent been substantiated yet. How are they allowed to get away with it ????
The vast majority of media is funded by advertising. When they're not funded by advertising, they're funded by sales. I trust that adequately explains the situation (i.e., if they don't get enough clicks, they go bankrupt and get replaced by the ones that _did_ get enough clicks - welcome to capitalism). Or, to put a different way: "There are seven main reasons - that they don't want you to know about! And you won't believe #5!"

It's interesting, isn't it, that one can make all sorts of assumptions, and yet the most obvious assumption - that it was made - seems so objectionable to so many.
Recently I have been doing a lot of thinking about the "accidental" universe idea. I do agree that our discoveries occur in that fashion but it seems as though the universe unfolds in increasing levels of complexity. It appears as though it is centered around the acquisition and transmission of information. Firstly, the organization of particles into atoms then into matter, allowing gravity to take center stage. Gravity is the mechanism with which the universe takes its form and function. Stars, planets, galaxies and cosmic web come to be. When certain conditions are met, higher levels of universal complexity occur on these planets; life and consciousness. Our discovery of AI seems to be a further level of complexity. AI is a tool that will allow us to gain a level of knowledge we may not have been able to obtain on our own. Maybe not, just my two pennies.
Would it not be easier to test for Life on Enceladus by gathering samples of the Icy Ring and looking for Frozen life that had been ejected there by the Water Spouts? Rather than attempting to drill into the surface!
The discussion we often have is that BSc graduates don't know what the sicnetific methods are, and even worse PhDs don't what the Philosophy of Science is! How many of you scientists know the difference between deductive, inductive and abductive reasoning? Even Sherlock Holmes got it wrong when he keeps talking about "the science of deduction",when in fact most of his investigations are based on induction!
Giant impact of large bodies or variable size bodies of significant sizes could indeed modify a regular dipping event into a rather odd wtf type scenario! It's only a theory but these events did and have occurred multiple times within our own solar system, along with planetary ejection, etc, thus these somewhat irregular events can or could be attributed to spacial body events that we are currently aware of within our own galactic/solar neighborhood, history!
The microphone is saturating. Either turn down the sensitivity or bend it away from the mouth some. It's disappointing... you'd want to think of the Ri as being world-class, but they fail to adequately soundcheck.
The closest star to earth is roughly 4.5 light years away. I’m not sure we’ll ever be able to verify life exists outside our planet unless it’s in our own solar system.
The universe seems empty to us but is it. You have to consider that a space radio source is unimaginable huge allowing the "waves" to travel the distance to our detectors which are unimaginable small. So this is the problem. We haven't built transmitters and receivers that can produce and receive signals to cover the great distances involved. At this point we haven't even considered the delay issue involved. Is this why the Cosmos seems empty! We just have to keep looking for a very very long time!
It might be considered funny when there's a 1000 to 1 ratio of click bait vs. genuine science on certain social media platforms, but it's less funny when we take into consideration that there are curious people who are just trying to learn and they have to deal with it. It's disgusting to take advantage of these people for profit.
I enjoy Chris Lintott's communication style; interesting, humorous and laid back. Good lecture. Thanks :)

It's only a theory but these events did and have occurred multiple times within our own solar system, along with planetary ejection, etc, thus these somewhat irregular events can or could be attributed to spacial body events that we are currently aware of within our own galactic/solar neighborhood, history!
The sound quality seems to get worse and worse at the royal institute, this is on par with a laptop mic, they really need to fix this.
The microphone is saturating. Either turn down the sensitivity or bend it away from the mouth some. It's disappointing... you'd want to think of the Ri as being world-class, but they fail to adequately soundcheck.
The closest star to earth is roughly 4.5 light years away. I’m not sure we’ll ever be able to verify life exists outside our planet unless it’s in our own solar system.
The universe seems empty to us but is it. You have to consider that a space radio source is unimaginable huge allowing the "waves" to travel the distance to our detectors which are unimaginable small. So this is the problem. We haven't built transmitters and receivers that can produce and receive signals to cover the great distances involved. At this point we haven't even considered the delay issue involved. Is this why the Cosmos seems empty! We just have to keep looking for a very very long time!
It might be considered funny when there's a 1000 to 1 ratio of click bait vs. genuine science on certain social media platforms, but it's less funny when we take into consideration that there are curious people who are just trying to learn and they have to deal with it.
It's disgusting to take advantage of these people for profit.
