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.
Always keep RS
If or when several of "our" planets align; Jupiter, Saturn, Uranus, etc… what would the signal appear like at 10k light years? Wt flux? Maybe a bunch of rocks still making their way together under gravity, orbiting the star.
I read the answer to the Fermi paradox just recently from a humble Youtube 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.
Excellent !!! 🙂
Billions of dollars, pounds, euros, rubbles, yuan, and yen etc, apparently being spent on 'The Search For Life Out There" and yearning for that magical day when we can communicate with those exotic 'Aliens' while billions of the same currencies being spent on snuffing out Life or squabbling and bickering in disagreement here on Earth!…..oh the irony.
Having said that, I'm also disappointed by Chris Lintott having to promote 'magical thinking' in his latest outings…is he being coached?…mmmm?
Very grateful.
I was there, but just watched through again 😁👍
Our Solar system is very kooky.
I feel that some being created our solar system to teach us, "don't make your planet like Venus, don't make your planet like Mars, don't m etc."
Yes! I'm in the video!!! I will be, a young white star, forming a eye in the HorseHead nebula
I've heard that the slow, peculiar rotation of Venus on its axis results in the same side of the planet always facing Earth when the planets are at closest approach. Venus is tidally locked with the Earth.
The Hubble was designed by a company that ordinarily made spy satellites. Somewhere, there is a YouTube video that shows the lead astronomer telling about a call he got from a technician at the manufacturer. The question was about the orbital height. This information is irrelevant for an astronomical instrument. The astronomer thought it odd that he was being asked the question, but he did not say anything about it seeming like an odd question. He just gave the answer.
My theory is that the technician was setting the design parameters using a CAD program from the 1980s. They had forgotten why the question in the CAD program would ask about orbital height. It was there to set the focus. A spy satellite would be a different distance to the target, depending on orbital height. An extreme telephoto lens (a telescope) is sensitive to variations in focal distance far more than is a wider-angle lens, so for a spy satellite (but not for an astronomical telescope), there will be a discrepancy between a low-orbit and a high-orbit instrument. An astronomical telescope should be set with 'an orbital height' set to infinity in the CAD program. If the astronomer had asked for the reason behind the question, the need for repair might have been avoided.
The problem is corrected by putting a washer of a different thickness, but that does not explain why the washer was of the wrong thickness to begin with.
Synchronicity and human brilliance is amazing. Wonderful talk!
Great presentation! But he needs a looser pair of jeans. He has a Robert Plant-like bulge that must have distracted an audience member or two. 20:09
Wonderful. BBC woke free science.
I LOVE DR. T!! I was an astrophysics major at LSU for 2 years and took her for a few classes!
is this how Saturn's rings survive – through near constant contributions from the ice blowing off Enceladus?
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. 🤣
Lovely talk. Thank you. 👍
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.
but where are all the smallish primordial black holes
the RI likes repeating lecture topics, i've seen this topic a dozen times or more! but, it is always interesting none the less
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!
I neglected to mention just how valuable the herbivorous dinosaurs poo has contributed to our chances of locating, utilizing and production of massive crop cultivation that feeds us all, which is an odd but wonderful aspect to poo!
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!
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!

We can’t even land on the moon after 50 years yet we can do the most complex things you can imagine with other things lol.
Did they discover gas on Uranus again? 😴
19:30 Maybe we don't hear anyone because we don't yet know how to to open a wormhole channel 😂
We now know everything we see is electric, atomes, molecules, light, name it and yet, not that long ago we knew none of it. What else we don't know of…
Great lecture 👌 👏
Can we not raise a new feild & dicipline of Objectivism? It does seem to be happening as
Most of those who study physics appear to spend more & more efforts working on subjective properties outside of their own self defined domains.
This should be from a blank slate perspective that isn't informed or held by the standard accommodations.
We have represented the old world whatsboutism really well even spent the most money in human history to try and prove them without luck .
We've used the inventions of our most essentric fundamentalistic ancestors to do so even though most of them would ask why we abandoned their most fruitfully eccentric ideas and inspirations ?
Take our most taught foundational ordering and categorizing skills it looks OK on paper ( like a football draft on paper it's a playoff roster) but in excersize the slightest variations can be argued a completely different species of losers. Plausible deniabilty loopholes embedded within have even experts talking past one another to the point we have no idenfiers to hold anyone accountable. No means to build concensus on defining what life is, what is a tribe, a nation a people place 0r thing..
If you went to school in uk or America 40+ years ago you was taught the most single origin given enough time & chances in universe that one random primordial soup on earth where space is a bottleneck. You would get in trouble asking where is the code of life measure & teachers was instructed to give all the arguments of Darwin and Lyle in opposition to all things phenotypical or epigenetics .
Modern explanatory power of dna would get you blackballed.
We seem OK with all these old eccentric alien hunters and reaching for the most Sci fi movies narratives if it stays within certain extremes.
As if this embedded plausible deniabilty wasn't bad enough ,
We seem to oppose nature dictating it's own 1st position orientation and direction and telling us how to properly order & speak of it .
We want to project our quality into it and make it say what we want to hear
شهاب سنگ ها همان سیارک های مشتری هستند که به دلیل جو زمین اون بارش های شهابی رو میبینید ولی امسال چند تاشون دارند به سمت زمین می آیند متاسفانه
و باید بررسی کنید
اگر در میدان دید تلسکوپ ها باشند میتوان فهمید و در غیر اینصورت نمیتوان
من هم دارم بررسی میکنم خودم
همین
یه آدم فضایی روی زمین هست
ولی بقیه بیرون منظومه اند برادر ،و شما
نمیبیشون 👽👻👻👻
زیاد مغرور نباشید و کشفیات رو انجام بدید
