1977 Carl Sagan Christmas lectures 1, the earth as a planet.
In his first Christmas Lecture, American astronomer and cosmologist Carl Sagan explores planet Earth and the place, scale and geometry of the “pale blue dot” in the Solar System.
Sagan provides a unique insight into the history of our knowledge of the third planet from the Sun, formed 4.5 billion years ago.
Using images and models of the planets in our Solar System, Sagan reveals how the heliocentric model of our universe, in which the Earth and planets revolve around the Sun, came to replace the earlier Aristotelian idea that our planet was at the centre and everything orbited around it.
As the complexity of observational tools has developed from simple telescopes to complex spacecraft, so too has our understanding of the world we inhabit. Looking back on the evolution in space science in the years since Sagan’s lectures we have made huge advances in our understanding of our planet’s environment, climate, weather, geology and biology — as well as our relative place in the universe.

I vividly remember this set of lectures. I was utterly gripped by them. From these lectures Carl Sagan gave me a love of science and astronomy that I still have today. I was 11 back then and I might add I had a crush on Prof Sagan as well. My parents bought me 'The Hamlyn Guide to Astronomy' around that time, I pestered them that much and they didn't have a lot of money….My Mum treated me to 'The Dragons of Eden' as well! Happy days…Sometimes at night even now I look out at the sky and say, "Hello Universe," so the impact on my life of these lectures cannot be underestimated. I miss Carl Sagan even though he passed away nearly a quarter of a century ago.
Just wonderful! I never seen these lectures!! Was this on the BBC?
Uranus 😁
The good old days when Pluto was considered a planet.
Privileged to share a birthday with this legend!
LOOK AT THE AMAZING WAY CARL HOLDS THE STUDENTS ATTENTION WHO ARE JUST SOAKING IN EVERY FASCINATING FACT OF OUR WORLD AND UNIVERSE ! A TRULY ENLIGHTENING EXPERIENCE !
Look how well dressed the kids are.
Planet. What a Dinnasoar idiot.
11:10: But we are at the centre of the universe. No matter where in the universe we might be, from our perspective we are at the centre. I think it's due to the nature of the big bang's expansion. Its difficult to explain. I'm not a theist by the way. I don't believe any of that religion crap.
I know it's pareidolia, but tell me you don't see a Walking Dead zombie face filling the face of Mars at (6:30)
A smart guy, not stellar, (pardon the pun), but certainly a benefit to humanity. The speaking cadence is interesting.
Thank for scientific community for all your contribution as it does explain mysteries when applied to spirituality. Here are two examples where advancement in our scientific understanding helped to understand spiritual truths:
1. This video goes over the Astronomical Explanation of World Cycle. https://youtu.be/YKxe-w8yI_s
2. Big Bang had been described in a Old Indian Text, Rig Veda in 3000 BC (best estimates from Scholars and Pandits). NASA-DIYA Sukta also known as Hymn of Creation. https://en.wikipedia.org/wiki/Nasadiya_Sukta
In my humble opinion:
The first and second describes what was before and right before Big Bang, respectively
The third paragraph, 3rdand 4the lines, describes the 380,000 years after Big Bang when light finally emerged.
The fourth describes the arousal of creative process and from there on….
why is it the older I get the less I believe
¡Carl Edward Sagan shared thought provoking and insightful information – i feel like a teenager when i see the names of Carolyn Porce and Michelle Thaller – Twitter prevents you from examining the activities of @maxrafaelwaller and @mrwaller3 per arbitrary suspensions! – written at 9:46 am Pacific Standard Time on Tuesday, 7 January 2020

I would think that most if not all of our professors today have armed guards who accompany them everywhere they go.
Carl and others are gone and we have a new quality of scientists.
Ones who ride in limousines and dine at the finest of places.
BECAUSE they are liars, they are paid to shut up and say what they are told to say.
I have watched over the years, we are at least stagnant ,and in the worst case we are de evolving by design.
I probably am one of the last people who have spent my entire life looking for the truth and not being deterred.
I am not a scientist , not in the scholastic way.
I am a human.
I have questions.
I have been told to shut up.
I will not comply.
Have a nice day/night/ life.
Truly, we do not know when our lives will end.
Nor what could come after.
No one knows.
No one.

The forefather of a new and exciting religion based on mathematical formula that hold no truth in reality.
I went there for a lecture in the 80's when I was at school. It was about liquid nitrogen and this guy kept throwing things in a vat of it and freezing things then smashing them. fascinating!
What a load of quakery utter utter utter moran Sudoscientist, with absolutley zero pratcical proof through a demonstartable experiment. All here say. You have to have a big belief to think this is reality. It is not what you think you know it is what you can prove.
Unbelievable .. do easy to follow .. miss him
Carl is awesome I can Listen to Him for Hours
poor man had no power point

astophysics is a lot of wild guessing —- faith based
