This talk was recorded at the Ri on 1 May 2024.
The cosmic mystery of extraterrestrial life has captivated humanity for centuries. Now, with leading-edge technology, the quest for tangible answers begins. Lisa Kaltenegger, founding director of Cornell University's Carl Sagan Institute, has assembled a multidisciplinary team of experts to craft a specialised toolkit for extraterrestrial exploration.
Lisa takes us on an enthralling journey across the Universe, utilising her theory that Earth can be used as a Rosetta Stone to decode the potential for life on distant planets. In this talk, discover some of the most extraordinary exoplanets, from those veiled in oceans of lava to solitary nomads adrift in space to others basking under the light of multiple suns.

Boy she sounds like bedtime stories to put you to sleep or maybe it’s the mic I don’t know but soothing voice
Good evening RI and Lisa
Lovely to see/recognise the Team behind your explorations and research so far.
Super exciting stuff.
😀
💜
I would not be surprised if an alien race in the Andromeda galaxy is looking at our galaxy, wondering if there could be life too.
Yes, that would be so, so, surprising if there were a planet around one of the hundred billion stars in the closest galaxy to ours where there were someone looking up at their sky seeing our galaxy and wondering.
Does my head in that when I was a kid, the idea that any other star *might* have a planet was still a thing, it seemed a reasonable conclusion yet absolutely no proof existed. What wonders await the children of today when they reach my age?
Thanks Lisa for this informative lecture, and again thanks RI for hosting.
She is very emotional and I will never know what accent this is. But this is marked for later, on the journey she will take us, for me towards sleep and dreams of the universe with a beautiful female voice.
No accent. American.
@@donc-m4900 Kuchl in Austria is definitely not America. Deaf ignorant.
So vivid and visual. Lisa is so fluent in imagination and her enthusiasm flows from every sentence she says. Wonder what it would be like to have coffee with her and just listen to her in person....dreamy. She is the perfect brand ambassador for science.
Not sure. Kinda sounds like listening to a Kamala Harris word salad.
I love this ladys voice and accent
Dr. Kaltenegger is an excellent lecturer.
Excellent talk, loved it.
I already knew all of this but I love a good bed time story
When I was in Astronomy 101 class in college in 1997 the textbook stated there were only 27 extrasolar planets found. Then and now what a difference in discovery 👍
If we consider the entire known universe….i believe it would be ‘harder’ for life, not to exist.. We are here, we exist, we are proof..
We cannot be a fluke. The universe is teeming with life. The problem is distance and time…
We are literally just taking our first steps on the mud when it comes to our knowledge gained so far and developed technology.
I was excited to see her as I had just watched an episode of "star Talk" with Neil DeGrasse Tyson that she was on. I only watched this about 3 days ago. Very interesting subject and an excellent approach to telling people about it. Keep it up Doc.
Four comma five billion years? Love the way that slipped in there.
RI, Are you planning to have Andrea Ghez for a talk?
nice calm style. she reminds me of Ann Druyan
Thank you!
Great job!
🖖
This was great and lovely speaking voice. Might be some ASMR in the future, I imagine I'll be re-watching this
To know the density and radius of a singularity written in google: singularity sphere in the heart of a black hole
WTF? This is so emotional, but she got me. Take me on this journey, please!
im 62 i remember when we didnt believe in other planets anywhere
no new news. but it is the first time i heard it presented like a bedtime fairy tale for 5 year olds. is it where the RI came to ?
This is like the 15th science video or lecture I've watched since that JRE episode with Terrance Howard and Eric Weinstein
meinem eier ist kalt von diesem style
Light or life. Our Earth is the master of learning!
Can we make smaller kite like Sails with solar panel shields like the parker probe.
& Push them faster..
An almost infernight number of planets in the universe what's the chance of little green men and Dialects existing
i want to visit these erse oneday, leaving this earse for other earse.
Neptune being 4 light hours from the sun means the diameter of the solar system is 8 light hours. 4.2 light years to the nearest other star is 36792 light hours. Divide by 8 gives 4599 solar system diameters, or cookies, not 9000.
"We do not know if there's life in the cosmos..." Life on Earth: "What are we, chopped liver?"
Ein sehr schöner Vortrag. Danke. Off topic, meine Frau will wissen, was Sie für einen Schal tragen. Sie meint, er könnte von Freywille sein.
You are teaching junior hi at Ri
Sorry can I have an opinion. After observing the movement of Protons and electrons and I think they are one and the same thing. It's just that such high speed makes them different.
Not physically different but they just look different because of the limitations of the tool's speed in capturing time frames and fps speed.
If we have a good enough tool and slow down the rotation. Then we will see that the electron positions will be more in the atomic nucleus.
This means that protons and electrons have the same energy.
With neutrons in the current point carrying one energy which we call Protons electrons.
Why does this energy (proton electron) have different neutrons because this energy is thrown into several currents.
But the consequence is if protons and electrons really have the same energy. So I have to say things that are beyond reason.
What's that?
That Mars is Earth's past. And the earth is the present of the earth. And Venus is the first future of the earth.
And the most terrible thing is that the second future of the earth is Mercury and the third future of the earth is the sun. The sun is the future of the earth.
This means that when we look at the sun, what we see is the earth in the future in a very, very long time in the future😢
But there is one more consequence. If Protons and electrons are the same thing. So there is only one human. When you see someone else then that is your past and one more person is your future.
So the past and the future are in the same movement.
If someone else feels happy then I will also feel happy because my mind sees me being happy in the future. 😢
If Venus is the earth in the future that means the sun will really come out from the west on the earth.
That means we have to prepare the planet Mars for our life. Because Mars is Earth's past.
"time" is the movement of energy, "the past" doesnt really exist as in, the energy has moved and interacted and changed organisation and it can never go back to that and everything is "now", energy can never get ahead of its own reactions. This is because any energy or matter changes based on whats around it and thats constantly different forever meaning overall the same energetic outcome can never repeat as it requires literally EVERY SINGLE QUANTA that exists to do exactly what it did before...which isnt possible due to the fact it changes based what just happened to it.
@@gaiustesla9324
Yes, I agree that time cannot go back to the past.
But what if the past, present and future run together.Running simultaneously. Can you imagine that?
I'm not saying time will go back to the past at all
I WONDER HOW ASSURED ARE WE THAT THERE IS ANYTHING REALLY OUT THERE BEYOND THE REASONABLE DISTANCE FOR US I.E.LIGHT YEAR...'CAUSE WE ARE LOOKING AT HISTORY WHEN WE GAZE AT THE STARS....AS I UNDERSTAND IT. WE CAN SAY THE MOON IS THERE, MARS IS THERE SUN WAS THERE 8 MINUTES AGO, ALL OTHER SYSTEMS ...MAY OR MAY NOT, WE CAN SAY THAT THEY WERE THERE BUT NOW WHO KNOWS......MY VIEW.
Jokes always land during RI talks.
Lisa would really benefit by considering the Universe as a work of creation.
Why?
@@davidswan4083 because so much of her work is about drawing conclusions based on sensible inferences. The biggest one is staring you right in the face. In fact she says in the video that we can look back in time and see how the cosmos began...no, we can look back and see that it began, but the "how" is left unanswerable.
Hearing how ignorant I was serprises me ! I guess I was never born so know nothing.
😎👍
She started by gushing, didn't stop, treated a highly educated audience as if they were kids. It was more about delivery than science. Perhaps her target was a dumbed down RUclips audience. Sorry but that's how I saw it.
🪐 🔭 👀 😃 👍
What's the point of RI lectures that tell us nothing new? Just to sell a book?
The next nearest star to earth is around 27 trillion miles away. Nobody is ever going there. The end.
😂 maybe yes maybe no
Not long ago, people thought we’d never have powered flight.
Also, with these search techniques, even if we might never go there, isn’t it worth just knowing if other civilizations exist?
@@peterfinegan3009 Well if it takes several million years to send a signal at the speed of light....then it takes several million years to come back....we wont be the "human species" anymore.
If you can basically never get to anywhere due to either you or the other thing ceasing to exist whilst you're trying to get there you might aswell class yourself as alone.
We will be the first aliens we meet, we'll have a baby in space, if that survives and goes well and people live outside of the earths atmosphere...they will eventually mutate into something alien.
For example on earth we say our civilisation is only a few thousand years old.....well that can disappear quite quickly.
I think we can already presuppose they exist but the universe is young, there hasn't really been time for life to develop.
Anyways, aslong as something like dna exists and forms atoms into life forms, "you" could be born anywhere in the universe at any time and it would seem "instant" to you just as you were born billions of years into this. So being born is the fastest way to travel without any travelling.
Never say never. As a species we are cantankerous enough to give it a try, well, just because.
It should be seen more a sign of the incredible rarity of life, that you're currently one of the most aware things in all of existence when compared to all matter and energy. Considering 99.99999999% of it has absolutely no clue anything exists yet it makes up near enough everything.
Good information, data, explanation. But why that artificial ASME type narration and tries to be funny (the jokes seemed to have fell so flat) ? It's not as if she's telling the story of a charming prince or a pretty princess for making kids fall asleep. She is enchanted/mesmerized/fascinated by what she has discovered but not everyone is/should be. Seems artificial many times. Just my honest personal opinion, others can agree/disagree.
No such thing as; Alien's! Just other worldly entities on a different wave length & time?
I highly encourage the organizers of this talks that they should bring some Indian monks to talk about Universe. The 8000+ years old Indian scriptures have all the answers. Quantum mechanic came from Upanishad, you never know what gems are still kept undiscovered in those scriptures.
No they don't. I've read a number of them, they add nothing to scientific findings except some aspects of psychology-- and that because of how the contents are written and viewed, not the contents.
If you disagree with the above, demonstrate your assertion with details about clearly-understandable statements in these books.
there are enough forums for bullshitters. RI is not the place for that, its a scientific institution
I tried. 8 minutes in and nothing useful or remotely interesting was said. Life's to short. On to the next lecture.
She isn't believable in her fake emotional performance. She talks like she's addressing grammar school students... Hope this isn't example of college professors teaching adults at crazy expense !!!
Magnetism bonding force of pressure must be very similar to earth's internal magnetic field grounding currents through its nucleus or core. That tells us that planets are out there. The composition of force of pressure has to be within the earth's internal magnetic field grounding currents. Different degrees of creativity from the Magnetism bonding force of pressure known as weightless outside of a greater internal magnetic field grounding currents through the nucleus or core like quantum internal magnetic fields of elements. Hydrogen has the strongest internal magnetic field of elements. As mass expands outward into occupational space within it. Force of pressure expands with equalization to cold repulsion within and without entanglement of mass. Mass falls in equalization to magnetism. Space itself is a weak external magnetic field filled with dark heat energy waves outside of entanglement of mass as potential renewable heat energy when entanglement with mass occurs. Heat is the lifeblood of everything and is the only universal force of energy. Normal space filled with dark heat energy singularities. Mass is multiple external heat energy singularities in internal magnetic fields grounding currents. Heat within atmospheres outside of entanglement of mass bouncing around randomly like lightning strikes disolving into external heat energy outside of internal magnetic fields disolving gasses lights up the atmosphere from refraction of light mirror affects. Heat unabsorbed magnifying refraction as light from repulsion to mass as potential renewable heat energy singularities like fireflies. Fire is quantum magnetic fields disolving as external heat energy outside of entanglement of mass as potential renewable heat energy singularities when absorbed into internal magnetic fields. Light doesn't travel heat does. Heat hits atmospheres and shows where the heat waves originated. Stars near and far away throughout space decaying atmospheres as dark heat energy singularities outside of entanglement of mass as potential renewable heat energy throughout space as a weak external magnetic field filled with dark heat energy waves. Black holes are external magnetic fields that don't ground currents through the nucleus or core where external magnetic fields cores are devoid of dark heat energy as pure cold repulsion of space itself as stars exploding away their heat energy outward force of pressure leaving behind unoccupied space as voids of heat energy and space itself is a weak external magnetic field that can't collapse in on the void like lightning strikes in atmospheres disolving internal magnetic fields into external heat energy waves into surrounding atmospheres lighting up and slamming shut on the void created by occupational space unoccupied by disolving gasses of heat overwhelming the cores of gasses like stars decaying their atmospheres. Atmospheres slamming shut on the void created by decay of mass in atmospheres collapse in on itself. In space as a weak external magnetic field, heat energy can only collect around the perimeter of absolute zero heat energy within as monopoles of pure repulsion to heat propulsion as pure generators of external magnetic fields that don't ground currents. External magnetic fields spinning all external heat energy within its field like a record player centrifugal force of pressure within and without entanglement of mass. The record spinning as magnetism. External magnetic fields are stronger than internal magnetic fields. Magnets show the bonding force of pressure and cold repulsion to and from cold space. Spheres throughout space show cold repulsion equalization to magnetism. Hurricanes equalization of force of pressure and distance traveling cycling circulation patterns as mass. Both internal and external magnetic fields are stronger at their cores or nucleus. Galaxies are formed around these external magnetic fields and prove hypotheses to magnetism. Light doesn't travel heat does. Two slit experiments prove hypothesis. Heat waves are random within atmospheres as potential renewable heat energy bouncing around of mass like fireflies lighting up surrounding atmospheres. Lightning strikes lighting up refraction of heat unabsorbed as potential renewable heat energy instantaneously disolving internal magnetic fields disolving into external heat energy unabsorbed immediately. Stars emit heat waves of singularities outside of entanglement of mass from disolving internal magnetic fields grounding currents of mass as atmospheres of stars. Fire disolving internal magnetic fields. Electricity is rapid heat exchanging through mass. Heat waves from space are normal heat propulsion outside of entanglement of mass. Renewable heat energy incoming doesn't all get absorbed, but the heat energy singularities absorbed must ground heat energy outgoing equalization. Aging is an unbalanced absorbion and outgoing heat energy singularity. When mass loses heat, it decays as aging. The speed of disolving quantum internal magnetic fields varies. Lightning is rapid heat loss instantaneously disolving internal magnetic fields. External heat energy outside of entanglement of mass is potentially renewable heat energy. Shivering is rapid heat loss. External magnetic fields spin all external heat energy within and without entanglement of mass like a record. A light bulb heats up, and heat waves pass through it and bounce around the atmospheres and into walls as refraction of unabsorbed heat energy singularities like fireflies or daylight. What star can't you look at because the heat is too intense and will burn your eyes out? Heat burns your skin and eyes. Sun glasses refraction of heat unabsorbed outward helps you see. Liquidity infinity to illusionary solidity of liquidity infinity as magnetism. Internal magnetic fields grounding currents into itself and surrounding mass as directional force of pressure. As mass is always outward force of pressure as weightless outside of earth's internal magnetic field. Within earth's internal magnetic field grounding, currents are force of weight. Table of elements proves hypothesis. Magnetism explains everything about the universal force of pressure from cold repulsion into cold repulsion as perpetual motion momentum of heat energy singularities propulsion momentum. Theoretically factual probability that works with quantum physics without gravity.
Please rewrite using observed data and coherent English.
Also note that magnetism doesn't work like that, and neither do planets.

i read a poem inspierd by your work
I have the hardest time with her accent. Not the 1st time. I kinda have to give up.
I think you guys don't know about India's most ancient books like ved , puran and many other books that tell us many universes are around our universe and many planets are around our planet earth and many solar are our solar these books you read and you thief are said to us you bloody thief doing research. Our books and scarepchuter tell us from thousands of years ago you have the shame on it we cannot say you guys are doing nothing but you have to respect us and respect those sant who searched it . please i request to all you western people give name to his research to our right person who research first
So true
They say nothing of the kind. I've read them.
If you disagree, present quotesand references from the books.
@@thekaxmax bhai reference mean you are inspired and respect to those books for your research but western people are get all books and full research item and theory and formula and many things you get on self name this is thiefing bhai
