Bob makes a very good point about attitudes in science. When scientists stop respecting each others' opinions, it stops being science. When we start to believe that other viewpoints represent some sort of "enemy" it becomes politics, not science. The truth is not decided by consensus; you don't "vote" for what is a fact or not. The scientific method is the best tool we have weighing evidence, but that's not being done when someone is playing politics. Science is about letting the evidence form our opinions. Politics is the art of changing people's minds. The two have nothing in common.
Exactly true! And this is where the anthropogenic warming crowd falls flat on their collective faces. They always tout "consensus by global scientists". They have manipulated data, shut down all serious discussions to the contrary. Bob is a tool for the Leftist politicians.
You are right Landrew0 and good comment. Unfortunately there is far to much politics in the science community. So much so that if you are a scientist that has a view point contrary to the political world, proven or not, you are ostracized. Just take a look at the life of Tesla. (Not the car). He was one of the most influential men of the modern age and was not very popular among his peers. I think it has been that way for hundreds of years. Call it pride or greed it does not matter. What really matters is that true science is the search for knowledge and the love of discovery. It has rules and laws that are far to often broken for the sake of pride or greed. It is to bad that people like Bob have fallen into this trap and are spreading it around. Starting with the first words out of his mouth talking about how man walked on all fours. Where is the proof from all the test you have done? Where is the fossil that shows evolution out side of a species ever existed? How about the lie that men and Dino's did not coexist. There are castles and grave stones that show they actually did. And how about global warming? I remember in the 80's when the world was supposedly getting colder and we were headed into a possible age of ice. Too bad for their foolish wisdom.
Scientists don't need to respect opinions. They need to apply scientific methodology and determine facts. Opinions don't make a functioning computer. Facts do.
rvnmedic1968 Questions: Who is "they"? Where is objective proof of data manipulation? How has discussion of opposing views been shutdown? Your arguments just don't stand up to objective scrutiny, no offense. Opinion is not fact.
The more I know, the greater is my understanding that I know so very little. Every time I learn one thing, the amount of things I don't know increases exponentially. I hate that it does that, and I love that it does that.
Pity the religious dont think like this. They claim to have all the answers in a book written by semi-illiterate goat herders who didn't know where the sun went at night.
It is maybe not so remarkable that you not only have a Greek name but also knowledge about Greek wisdom. Well done! (Coming from a Greek person) What you said in Greek: Eν οίδα ότι ουδέν οίδα. Meaning "one (thing) I know, that I know nothing".
Socrates walked around Athens asking people who were supposed to be knowledgeable what they knew and how they knew it. He concluded that they, as well as he, really knew nothing. For example, he concluded that the greatest writers were really idiots who were inspired by the Gods, but didn't understand what they had written.
I used to know everything - literally EVERYTHING...when I was 17 years old. I wish I would have written it all down so we could understand all these things that science still doesn't know, but I was too distracted by fun stuff and since then I've known less and less and now I barely know anything. Sorry for letting you all down.
That's alright, Heather. But you may take some (a lot, really) comfort from the wise Socrates, my hero and mentor. He said that the most reliable indicator of wisdom is the ability to admit you know nothing. It's all uphill from there. Carry on. You're well on your way.
@@robertthompson2191 I don't know because I seem to have lost all that vast knowledge. All that is left is a memory of how certain I was that I knew everything there was to know. Maybe all I had was that certainty but it seemed so authentic that it's hard to imagine it wasn't accompanied by the relevant knowledge.
Heather was being beautifully ironic. Has that art deteriorated to the point where we can no longer recognise it? Didn't you notice, Swishaleo, that all seventeen year olds know everything--for a time?
Still waiting for the "Everything" wrong part? How about a talk about our entire existence of how we have been lied to about everything, finance, science, engineering, medical, religion, energy, gravity, space.....etc.
30 years ago, a far more plausible understanding of reality was achieved by Humans, Dr. Milo Wolff.. "Commendation from NASA for research work at Massachusetts Institute of Technology on the Earth's atmosphere and the Moon's surface for navigation of the Apollo spacecraft to the Moon.. Dr. Milo Wolff has found the structure of the electron consisting of two spherical quantum waves, one moving radially outward and another moving radially inward. The center of the waves is the nominal location of the electron 'particle'. These waves extend infinitely, like charge force. All 'particle' waves mix and contribute to each other, thus all matter of the universe is interrelated by this intimate connection between the fundamental 'particles' and the universe. The natural laws are a direct consequence of this Wave Structure of Matter (WSM), thus WSM underlies all of science." Ever since then there has been exponential growth in false cosmological ideas spreading over 'social media', and corruption generally throughout the world. The great problem for Humans is that we have not evolved in knowledge of our existence, and have therefore made up 'societies' from foundations of falsity and corruption. Understanding fundamental truth (how things exist) is key to living genuine lives. As Eric Lerner explained.. "History abundantly shows that people's views of the universe are bound up with their views of themselves and of their society. The debate in cosmology has implications far beyond the realm of science, for it is a question of how truth is known. How these questions are answered will shape not only the history of science, but the history of humanity." (Eric Lerner, 1992) So current 'science' is still being funded by agencies invested in old and therefore corrupt intention. Not to discover truth about reality, but to cover it, bury it, disguise it, ignore it..anything other than acknowledge even its existence.. The 'particle' physics paradigm represents old and illusory contradictions/hypocrisy, and wave physics will give us a chance of existing from a foundation of truth.. the wave structure of matter spaceandmotion
All I can say my friend if you didn't hear anything that wasn't true you're a very lost soul. And you need serious help because you have been heavily indoctrinated. Please read my comment about yours you might learn something.
I think I’m right about everything. If I thought I was wrong, I’d change my mind and then l’d be right. Of course, everything I know is wrong, because language only approximates thoughts, and thoughts only approximate reality. At least I’m right about that.
Indeed, but the world was successfully split in two by fake info and the conflict is now with the "revolutionary anti-everything", most of them illiterate who 30 years ago would not dare to lecture "science" in public. Big success of the dictatorship regimes, which will survive thanks to this trick.
What an amazing science host. He extremely good at dumming down scientific talk so the common guy can understand it. It certainly shows that he has a pretty high level of science understanding on his own. And he has a great sense of humor. Thanks Bob.
Im 70 and a pilot and love science... all adults i've ever talked too in live. Alot ! ....people DO NOT even know the sun is a star. I have to tell them. They haven't EVER thought about what it is....it just makes light 🇺🇸
Thank you! This is where I live: optimism based on human potential in the face of daunting global problems, mostly of our own making. We have to step up, it's what we are here to do, I believe. There is no Planet B.
The problem with humanity is covetness and greed. And those that suffer the most from these things are people. And the ones that promote and act upon these the most are dingbats that somehow beleive they are in charge of everything. I hope i said that correctly
@@oakleydavid7619 Humans have not always been greedy. It's a result of scarcity (not having access to things) that we have become this way. The reason why don't have access is due to property laws and corporate greed which restricts access in order to gain profit in the monetary system. Think of the game Monopoly...it ends when there is only 1 player left that has all of the properties and all of the money. That's the game the world is currently playing. Maybe we need to tweak the game so that it never ends and players never go bankrupt...
He said we don't know everything about everything - saying that screwing up our planet is bad for our species is not some unknowable thing. I love how people with an agenda can take anything out of context to fit their narrative.
"Ted talks are church for lefties.." What an arbitrary analogy to draw between the spreading of facts and the spreading of denial of the empirical world. Only difference is science calls out what it didn't know before. Religion just keeps on with what's unprovable. Climate change is real🤯
My bottom line on this discussion is that we would be better served to prove that we are as smart as the lecture suggests and embrace the science. Life here on our home planet is our top priority before we take any more steps to reach for the stars. That's what the invitation to the party is about, finding a way to unite a common core to establish longevity here on mother earth. He says we can do that and I want to be as optimistic. If we can, will we?
Hands down the best TED talk I've seen in a while, probably ever. Old dude there is definitely the kind of crazy I aspire to be, which is not even crazy as in pure madness, it's enlightment.

I think you’re the one facing a conundrum. You want to sound clever offering what you believe is a flaw in his logic while not understanding his logic at all. The argument is that individual human perspective is fundamentally flawed and biased. When humanity bases knowledge off of objective fact rather than personal beliefs our understanding of truth becomes more consistent and accurate.

@@vv-mc7io O.K, Grant Perkins was joking and it was funny. However, isn't the main thrust of McDonald's argument that man/woman has always been 'wrong' in as much as we are constantly having to fine-tune and even change what we know as further facts/discoveries are uncovered? Maybe we are becoming 'less wrong' in comparison to our ancestors, but I think that is the point of his argument. That is beside the warning concerning the future of our fragile ecosystem.
Glad to see that he's honest enough to admit that scientists don't understand or even know what %95 of the universe is or how it works. Every generation thought they understood the universe but time proves them wrong and we are no different.
Every generation gets things right AND wrong about the universe. I think our generation is way ahead. Scientists understand many, many aspects of the big picture. All, no. Why the universe should be as it is may never be answered.
When we learn something about the universe, it usually leads to a better understanding of what we don't know. Careful observation and a lot of deep thinking went into the realization that we don't know what is bending light in some parts of the universe and why the universe is expanding at an increasing rate.
The only good point he made was that we know today that most of the science we believed throughout history was wrong. What reason do we have for thinking that NOW we’re right?

In my humble view, they all appear to be nothing more than a bunch of self-congratulatory fools. who believe in pseudoscientific nonsense. 'falsely or mistakenly claimed or regarded as being based on scientific method: "the pseudoscientific nonsense of their theories" · "pseudoscientific beliefs like astrology" '
He is talking more about what we don't know than about whether the things we think we know are true...or not. Science is often built on previous knowledge, so if we build on something that we get wrong (but don't know it is wrong) then from that moment on science is an illusion as well and we are not in the reality we think we are. .

I would love to talk with him about what the Bible says about the earth and how it was made. Seriously I think it it would be fun and enlightening for both of us
@Chris Russell what if they do care but we don't have the intellect to understand the potential of those single cells. You know, someone did a 7 year study on plants and the root systems of these plants started growing toward the sound of water... Which wasn't even water, it was just the recording of a river nearby.
@An Ominous Anonymous : which proves how gulible plants are. @Anita Hyche : thanks for your comment, avoided me putting in that same data. I was so triggered when he said that we were the first species to transform the atmosphere... weird coming from a scientist. I bet he keeps mailing TED to remove that comment.
This moron refers to CO2 as if it were pollution, but is the second most important constituent of the atmosphere (behind oxygen). The entire biosphere (including humans) depends on the transformation of CO2 into carbohydrates, and contrary to the peer pressured review literature, we are perilously close to the MINIMUM concentration of CO2 required for photosynthesis.
Love the talk, but just gotta say, we are NOT the first species to change the chemistry of the atmosphere. How do you think we got so much oxygen in our atmosphere??? It's called plant life! Algae, etc... Other than than, yes, great talk. :)
I think he meant we're the first to drastically change the atmosphere in a very very negative way. Unlike plants that provide positive chemicals that make earth MORE habitable
@@motn2017 The introduction of oxygen into our atmosphere was VERY negative for the organisms at that time. O2 was very toxic for nearly all of them. At a quite fast pace evolution had to establish complex mechanisms to detoxify reactive oxygen species (ROS). Those organisms failing to do so were doomed or had to retreat to habitats free of oxygen.
1.) The part folks missed right @7:47: "So have we figured it all out? Does that mean that everything we know now is right? Not quite." 2.) It's waaay too easy to tell who actually watched this.

What if everything you were taught is wrong. But then he agrees with everything we've been taught since grade school that most of us have already figured out wrong.
I've known this fact since the 1960s when Firesign Theatre told me that everything I know is wrong. 50 years later I still know that everything I know is wrong, including that which I just said that I know.
An acre of a solar farm covered with panels, destroys the acre of land it is placed over. One acre for one acre. It sounds small, and perhaps it is, but placing a solar panel between the sun and the ground, essentially changes the one acre of ground near 100%. It removes or reduces the plants which grow and it deprives that acre of normal rainfall. The panels will concentrate the ran along run off panels which can lead to MORE not less soil runoff. It is easy to make GRAND PRONOUNCEMENTS, but the reality of them are different.
If we wanted to, meaning if there was a global agreement, we could easily cover one or two huge deserts with solar panels, providing the energy for the whole world. The truth is, we already have a solution for every problem facing mankind, except stupidity.
that is why he stated that we are bad at "catching" the energy from the sun, what if the panels were 10 times as efficient? it would take 10 times less space for the same energy we can collect today, saving up to 90% of the space, so that the ground doesnt need to be affected.
@Scott Derry for the greater good trillions of taxpayers money would make up for it. The reason nobody is acting on it is because humans are naturally selfish, we dont want to preserve for the future, rather burn up what we have now for ourselves.

@@lemer1463 no, actually the brighter the star burns, the faster it goes off, that's why red/white dwarfs will be the last stars around when everything dies.
@@thegreathusain the faster something burns, the more magnitude it has. which means it loses its mass in doing so and getting smaller. Im trying to relate that to time if that makes sense as it seems to me that stars burn the most but live longer than the surrounding objects (planets etc) as due to gravity it could be very likely that the surrounding objects find their death by falling into the stars orbit.
Do you know what dark matter and dark energy have in common with the double slit experiment? When you take a good look at what is too small or too big, you can see the flaws in the simulation. And what creeps me out is the possibility that the ones running the experiment may be thinking "It's that time again. They've become advanced enough to see what they shouldn't. Let's reboot."
Astronaut Don Petit admitted they lost that technology. Fact is Stanley Kubrick staged the whole thing. The Earth is not a ball, nor is it moving. Prove it for yourself.
@@EvenStarLoveAnanda Yes a sunset does prove the Earth is flat. Notice the reflection of the light from the Sun off the face of the water. Of course this phenomenon which every person can observe is simply impossible if the water was curved. It is a simple experiment anyone can do. Shine a light on a curved surface and compare that to a flat surface. Also look at the sunset and notice how the light follows the Sun - this effect is impossible if the Sun were 93 million miles away. And yes you can measure the distance to the Sun using shadow angles and confirm it is relatively much closer than the followers of the Baal Earth religion claim. Notice also the crepuscular rays of the Sun. Another optical proof the Sun is above the clouds.

Bob's an excellent interviewer on his CBC Quirks & Quarks show. However, I've belatedly concluded his talents are likely somewhat more mundane than I once thought, rather than unique. I used to think he had the most amazing ability to spontaneously ask incredibly perceptive, relevant, intelligent questions of his scientist guests! I still admire the quality of his questions, but it belatedly dawned on me most of his questions are likely pre-prepared, not spontaneous, and that he already knows answers to most of them. Bob and/or CBC producers likely read the scientists' published studies, identify their most important and interesting aspects, and then write questions that will help ensure the scientists address those key points. In fact, it's very likely they also ask the scientists to send CBC lists of questions ahead of time Bob should ask, whose answers will best elucidate the scientists' work. I've learned this is fairly standard practice among talk shows that have hosts asking guests questions. They will have the guest provide them with a list of questions ahead of time. In my naivety, I used to think Bob demonstrated spontaneous brilliance with his questions, rather than demonstrating careful, diligent, professional preparation. It's in the planning, folks.
Hermesacat you can tell it's scripted when the scientist tells bob "that's a great question " to plant in our head that it is a great question so we follow the predicted programming to accept anything the white coats say in this age of scientific dictatorship. Hope that helps

'What if Everything You Know is Wrong' Knowledge is passive. In other words, in order to know, something must be given to the knowledge, because knowledge does not create its objects. The sensitivity must be informed, it must receive something. The sensitivity must be affected. This is the first step. The second step is what is received is processed, the end of this is the interpretation. It is in this perspective that what we know is the world of phenomena. And a phenomenon is the objective representation of the sensitive reality. Therefore everything we know is true according to our psychological relativity. In other words, we can't know in absolute term.
Bob certainly could recognize that we always seem to find a way and we do continually advance knowledge and technology. You must understand the journey will leave too many in its wake if its not controlled. Truly educate our society and then they can get on board for a faster ride. weeeeeee
Exactly. He just seemed to pander for applause regardless of the topic, even going as far as that awkward self pat on the back for 40 years in his field. The women’s rights thing had virtually no segue way and really has no place in this talk. Which rights exactly? At least as far as things go for women in the west...Now there are lots of other places in the world that need to seriously address dozens of very serious issues of women’s inequality from A-Z. Although I’m sure any attempt we try at liberating these women would be looked at as cultural appropriation from the West
Can't wait to share this talk with my students! I've been a fan of Bob McDonald and "Quirks and Quarks" for years and to see this talk really inspired me to commit to some changes this year. I'll see you in 6 million years--we can do it! :)

One of the first things a historian of science learns is to allow the people who lived long ago to have a reasonable world picture. That is, to concede that their way of conceiving the world is a reasonable one. When someone who has an impoverished view of the history of science speaks about how "wrong" everyone before us was, the speaker betrays his lack of historical imagination.
You missed the point completely. Also I will add that letting isn’t always a bad thing. Try donating blood regularly. I have ab- so I’m asked a lot. Plus I’m cool just giving. Rare type in all. My dr told me that removing blood and allowing new blood to replace has many benefits. Just saying
@@asiseeit2041 Yes, it is likely (I too, have donated frequently) that the good feeling which follows bloodletting may well have contributed to the idea of its health-promoting qualities. Yes, it is not a question of whether or not bloodletting is healthful, but whether people in the past had any rational basis for their views of the world. Calling them "wrong" betrays a presentist arrogance.
...AND, EVERYTHING IS ENERGY. Mass is energy, light is energy, sled on a hilltop is energy, sled speeding down the hill is energy. Einstein said it, "Everything is energy." And energy warps space-time. And separate warp-space attract. We call it "gravity".
the average temp on Earth is 17 ° C the space around d the Earth outerspace that is to say is about -270°C this difference is huge and there should be a way to exploit this differential as an energy source . conversely the perfect vaccumm of space is another potential exploit that can be tapped to make energy
the mass per volume(of space) ratio would be so small that it wouldnt really make sense to try. Theres only about 6000 atoms per cubic metre in outer space which we can use to get energy. And even with 100% efficiency it would net much less energy than is needed just to stay operational.
then what would you do? cause all (known) methods that convert temperature differences into other forms of energy wouldnt make sense to do in this scenario. Change in energy for lowering or heightening temperature of an atom is MUCH less than the energy from fusion/fission from the same atoms. For perspective. 1 gram of hydrogen nets about 1 gigawatt from fusion processes. but gathering 1 gram of it in space would require 5.9747022e+26 cubic meters, and this is if every single atom in space was hydrogen. This is more than 1000 x bigger volume than the earth. And this is for fusion, not harvesting energy from temperature difference Do you see the problems with getting net energy from this yet?
Yes, and in some millions of years some strange animal will thank us for what we did, now... But we will not be there to see it... becurse we did it 🤐😴😜

Sorry, Luis, but you fail to understand how science works. It is not about opinion but about evidence. It's about observing the universe/reality, creating hypotheses based on those observations and then testing them. No hypothesis can be proven to be true or false since we lack a 100% understanding of how the universe/reality works. We have to muddle along gathering knowledge as we go and must be prepared to toss aside information that is proven wrong through experimentation. The title is accurate as we can't prove anything we know to be right but only proven wrong based on experimentation. It is frustrating to not have unassailable knowledge but the scientific process (and it is a process) is the best way for us to figure out how the universe/reality works.
@@briguy677 So explain to me how when scientists followed the scientific method and their findings were 100 % accurate other scientists or theorists negated the results based only on believes and philosophical impossibilities? Im talking about the Michaelson Morley experiment negated by a theorist Einstein and inventing his relativity theory in the process. So yes , everything we are told is based only on who is in charge and who will benefit from the specific findings. Its a sad true but we have been told only what the people in power want us to know and no more.
@@luis-alvarez929 You have proven with this post that you really don't understand how science works. The Michelson-Morley experiment failed to find evidence for their predictions that there was an aether permeating space which allowed light waves to pass through the vacuum. No one, including Einstein, negated anything regarding the undertaking. In fact, it was more along the opposite lines. Michelson and Morley's failure was evidence that the theory of relativity was correct. The scientific process wouldn't work if it was based on an argument from authority. In fact, it's the complete reverse. Scientists are constantly trying to prove one another wrong, not because they are dicks, but rather because they want to discover evidence for what is true. By the way, the Michelson-Morley experiment has been repeated a number of times (the latest in 2006) with equipment far more fine-tuned than in the original experiment and every time it has failed to produce positive results. This continues to support Einstein's theory of relativity is most likely correct.
@@stuartfoster7582 Theories can't be "proved" to be "true" the point is they have yet to be proven to be wrong. The idea is to predict how/why something works and then find evidence that either proves the prediction wrong or finds evidence that upholds the prediction.. Even if a prediction holds up now doesn't mean it's true or necessarily correct as future tests or evidence could prove it wrong.

"In general, we look for a new law by the following process. First, we guess it. Then we compute the consequences of the guess, to see what, if this is right, if this law we guess is right, to see what it would imply and then we compare the computation results to nature, or we say compare to experiment or experience, compare it directly with observations to see if it works. If it disagrees with experiment, it’s wrong. In that simple statement is the key to science. It doesn’t make any difference how beautiful your guess is, it doesn’t matter how smart you are who made the guess, or what his name is… If it disagrees with experiment, it’s wrong. That’s all there is to it.” -Richard Feynman

When we start to believe that other viewpoints represent some sort of "enemy" it becomes politics, not science. The truth is not decided by consensus; you don't "vote" for what is a fact or not. The scientific method is the best tool we have weighing evidence, but that's not being done when someone is playing politics.
Science is about letting the evidence form our opinions. Politics is the art of changing people's minds. The two have nothing in common.
Exactly true! And this is where the anthropogenic warming crowd falls flat on their collective faces. They always tout "consensus by global scientists". They have manipulated data, shut down all serious discussions to the contrary. Bob is a tool for the Leftist politicians.
You are right Landrew0 and good comment. Unfortunately there is far to much politics in the science community. So much so that if you are a scientist that has a view point contrary to the political world, proven or not, you are ostracized. Just take a look at the life of Tesla. (Not the car). He was one of the most influential men of the modern age and was not very popular among his peers. I think it has been that way for hundreds of years. Call it pride or greed it does not matter. What really matters is that true science is the search for knowledge and the love of discovery. It has rules and laws that are far to often broken for the sake of pride or greed. It is to bad that people like Bob have fallen into this trap and are spreading it around. Starting with the first words out of his mouth talking about how man walked on all fours. Where is the proof from all the test you have done? Where is the fossil that shows evolution out side of a species ever existed? How about the lie that men and Dino's did not coexist. There are castles and grave stones that show they actually did. And how about global warming? I remember in the 80's when the world was supposedly getting colder and we were headed into a possible age of ice. Too bad for their foolish wisdom.
@@rvnmedic1968 How can you say "exactly true", and then do the same thing that he just warned against...
Scientists don't need to respect opinions.
They need to apply scientific methodology and determine facts.
Opinions don't make a functioning computer. Facts do.
rvnmedic1968 Questions: Who is "they"? Where is objective proof of data manipulation? How has discussion of opposing views been shutdown? Your arguments just don't stand up to objective scrutiny, no offense. Opinion is not fact.

Socrates walked around Athens asking people who were supposed to be knowledgeable what they knew and how they knew it. He concluded that they, as well as he, really knew nothing. For example, he concluded that the greatest writers were really idiots who were inspired by the Gods, but didn't understand what they had written.
I used to know everything - literally EVERYTHING...when I was 17 years old. I wish I would have written it all down so we could understand all these things that science still doesn't know, but I was too distracted by fun stuff and since then I've known less and less and now I barely know anything. Sorry for letting you all down.
That's alright, Heather. But you may take some (a lot, really) comfort from the wise Socrates, my hero and mentor. He said that the most reliable indicator of wisdom is the ability to admit you know nothing. It's all uphill from there. Carry on. You're well on your way.
the regret of ignorance cuts deep. but wishing will not give back that knowledge- only actively searching for it will do. i hope for the best.
So how is it that you knew everything at 17? Just curious.
@@robertthompson2191 I don't know because I seem to have lost all that vast knowledge. All that is left is a memory of how certain I was that I knew everything there was to know. Maybe all I had was that certainty but it seemed so authentic that it's hard to imagine it wasn't accompanied by the relevant knowledge.
Heather was being beautifully ironic. Has that art deteriorated to the point where we can no longer recognise it? Didn't you notice, Swishaleo, that all seventeen year olds know everything--for a time?
Scientists, even more than the rest of us, should remain open to the possibility that everything they think they know could be wrong.

Yes, his point is the exact opposite of what I thought it would be. And yes, the whole movement was to convince us NOT to believe our own senses.
30 years ago, a far more plausible understanding of reality was achieved by Humans, Dr. Milo Wolff..
"Commendation from NASA for research work at Massachusetts Institute of Technology on the Earth's atmosphere and the Moon's surface for navigation of the Apollo spacecraft to the Moon..
Dr. Milo Wolff has found the structure of the electron consisting of two spherical quantum waves, one moving radially outward and another moving radially inward. The center of the waves is the nominal location of the electron 'particle'. These waves extend infinitely, like charge force. All 'particle' waves mix and contribute to each other, thus all matter of the universe is interrelated by this intimate connection between the fundamental 'particles' and the universe. The natural laws are a direct consequence of this Wave Structure of Matter (WSM), thus WSM underlies all of science."
Ever since then there has been exponential growth in false cosmological ideas spreading over 'social media', and corruption generally throughout the world. The great problem for Humans is that we have not evolved in knowledge of our existence, and have therefore made up 'societies' from foundations of falsity and corruption. Understanding fundamental truth (how things exist) is key to living genuine lives. As Eric Lerner explained..
"History abundantly shows that people's views of the universe are bound up with their views of themselves and of their society. The debate in cosmology has implications far beyond the realm of science, for it is a question of how truth is known. How these questions are answered will shape not only the history of science, but the history of humanity." (Eric Lerner, 1992)
So current 'science' is still being funded by agencies invested in old and therefore corrupt intention. Not to discover truth about reality, but to cover it, bury it, disguise it, ignore it..anything other than acknowledge even its existence.. The 'particle' physics paradigm represents old and illusory contradictions/hypocrisy, and wave physics will give us a chance of existing from a foundation of truth..

What an arbitrary analogy to draw between the spreading of facts and the spreading of denial of the empirical world. Only difference is science calls out what it didn't know before. Religion just keeps on with what's unprovable. Climate change is real🤯

Life here on our home planet is our top priority before we take any more steps to reach for the stars.

Maybe we are becoming 'less wrong' in comparison to our ancestors, but I think that is the point of his argument. That is beside the warning concerning the future of our fragile ecosystem.
Grant Perkins yeap another lost soul
Glad to see that he's honest enough to admit that scientists don't understand or even know what %95 of the universe is or how it works. Every generation thought they understood the universe but time proves them wrong and we are no different.
Every generation gets things right AND wrong about the universe. I think our generation is way ahead. Scientists understand many, many aspects of the big picture. All, no. Why the universe should be as it is may never be answered.
When we learn something about the universe, it usually leads to a better understanding of what we don't know. Careful observation and a lot of deep thinking went into the realization that we don't know what is bending light in some parts of the universe and why the universe is expanding at an increasing rate.
That doesn't equate to 'we're currently wrong about 95% of what we now think we know'.
And whenever we discover that science got something wrong, it's always because of more and better science.
95%...
The only good point he made was that we know today that most of the science we believed throughout history was wrong. What reason do we have for thinking that NOW we’re right?

Viverntahl he said change the chemistry of the atmosphere, plants and humans are different, he just used the wrong word to say “mammal-animal”
This moron refers to CO2 as if it were pollution, but is the second most important constituent of the atmosphere (behind oxygen). The entire biosphere (including humans) depends on the transformation of CO2 into carbohydrates, and contrary to the peer pressured review literature, we are perilously close to the MINIMUM concentration of CO2 required for photosynthesis.
Love the talk, but just gotta say, we are NOT the first species to change the chemistry of the atmosphere. How do you think we got so much oxygen in our atmosphere??? It's called plant life! Algae, etc... Other than than, yes, great talk. :)

I think he meant we're the first to drastically change the atmosphere in a very very negative way. Unlike plants that provide positive chemicals that make earth MORE habitable

@@motn2017 The introduction of oxygen into our atmosphere was VERY negative for the organisms at that time. O2 was very toxic for nearly all of them.

An acre of a solar farm covered with panels, destroys the acre of land it is placed over. One acre for one acre. It sounds small, and perhaps it is, but placing a solar panel between the sun and the ground, essentially changes the one acre of ground near 100%. It removes or reduces the plants which grow and it deprives that acre of normal rainfall. The panels will concentrate the ran along run off panels which can lead to MORE not less soil runoff. It is easy to make GRAND PRONOUNCEMENTS, but the reality of them are different.
Bambi Able OR what if we just place the panels on the roofs of houses and buildings which already cover thousands of acres of land?
@@Mills354 or replace the roadways with solar collecting panels instead of asphalt and concrete? The technology already exists to do it.
If we wanted to, meaning if there was a global agreement, we could easily cover one or two huge deserts with solar panels, providing the energy for the whole world. The truth is, we already have a solution for every problem facing mankind, except stupidity.
that is why he stated that we are bad at "catching" the energy from the sun, what if the panels were 10 times as efficient? it would take 10 times less space for the same energy we can collect today, saving up to 90% of the space, so that the ground doesnt need to be affected.

Bob's an excellent interviewer on his CBC Quirks & Quarks show. However, I've belatedly concluded his talents are likely somewhat more mundane than I once thought, rather than unique. I used to think he had the most amazing ability to spontaneously ask incredibly perceptive, relevant, intelligent questions of his scientist guests!
I still admire the quality of his questions, but it belatedly dawned on me most of his questions are likely pre-prepared, not spontaneous, and that he already knows answers to most of them. Bob and/or CBC producers likely read the scientists' published studies, identify their most important and interesting aspects, and then write questions that will help ensure the scientists address those key points. In fact, it's very likely they also ask the scientists to send CBC lists of questions ahead of time Bob should ask, whose answers will best elucidate the scientists' work. I've learned this is fairly standard practice among talk shows that have hosts asking guests questions. They will have the guest provide them with a list of questions ahead of time. In my naivety, I used to think Bob demonstrated spontaneous brilliance with his questions, rather than demonstrating careful, diligent, professional preparation. It's in the planning, folks.
Hermesacat you can tell it's scripted when the scientist tells bob "that's a great question " to plant in our head that it is a great question so we follow the predicted programming to accept anything the white coats say in this age of scientific dictatorship. Hope that helps

'What if Everything You Know is Wrong'
Knowledge is passive. In other words, in order to know, something must be given to the knowledge, because knowledge does not create its objects. The sensitivity must be informed, it must receive something. The sensitivity must be affected. This is the first step. The second step is what is received is processed, the end of this is the interpretation. It is in this perspective that what we know is the world of phenomena. And a phenomenon is the objective representation of the sensitive reality. Therefore everything we know is true according to our psychological relativity. In other words, we can't know in absolute term.

He's such a great presenter. Great talk. Very engaging.
Very wrong
What an amazing and inspiring talk.
This talk was full of fiction.
All wrong
Bob certainly could recognize that we always seem to find a way and we do continually advance knowledge and technology. You must understand the journey will leave too many in its wake if its not controlled. Truly educate our society and then they can get on board for a faster ride. weeeeeee
One of the best Ted talks I've seen. ☮️☯️❤️
NOT! 🤮
Great, but why the PC statement. That's not science.
Exactly. He just seemed to pander for applause regardless of the topic, even going as far as that awkward self pat on the back for 40 years in his field. The women’s rights thing had virtually no segue way and really has no place in this talk. Which rights exactly? At least as far as things go for women in the west...Now there are lots of other places in the world that need to seriously address dozens of very serious issues of women’s inequality from A-Z. Although I’m sure any attempt we try at liberating these women would be looked at as cultural appropriation from the West

Can't wait to share this talk with my students! I've been a fan of Bob McDonald and "Quirks and Quarks" for years and to see this talk really inspired me to commit to some changes this year. I'll see you in 6 million years--we can do it! :)

Hello from 2019!
And there is the Sphynx....been covered in sand for ..who knows how long, and when we dug it out of the sand ..what did we find? That, before it was covered in sand, it had been suffering from rainfall erosion (for another very long time). There is no doubt that the Sphynx has "lived through" ENORMOUS "climate change" ..none of it brought on by "man".
ok but current man made climate change is still real
Plastic has poisoned the planet. My grandparents, who lived before the age of plastics, never knew cancer.
"Everything" is a huge generalization, never go full generalization, never.
Very funny!! ; {)
"never go full generalization" ? Never say NEVER!
Nothing is as boring as a superlative laced thought.
Yer NEVER
Don't look at me...ever!
Also, Greenland ice cores say that we are in the most stable climate period in recent history.
No, they do not.
yes... yes they do.
Provide the evidence.
All I Understood is, añy direct or serious reaction on a serious subject will just scare the people away. A little Humour helps even in the most intense situation. The guy doesn't look serious but he is really serious but his seriousness on the state of our planet is forcing him to not look too serious when he is discussing something serious.
Let's not take this planet for granted

Took a long time to realise...thanks for sharing?
One of the first things a historian of science learns is to allow the people who lived long ago to have a reasonable world picture. That is, to concede that their way of conceiving the world is a reasonable one. When someone who has an impoverished view of the history of science speaks about how "wrong" everyone before us was, the speaker betrays his lack of historical imagination.
very well put
You're right, we should respect the soothsayers, entrail readers, and the folk who claimed the world is flat. Bleeding out the sickness was GENIUS.
You missed the point completely. Also I will add that letting isn’t always a bad thing. Try donating blood regularly. I have ab- so I’m asked a lot. Plus I’m cool just giving. Rare type in all. My dr told me that removing blood and allowing new blood to replace has many benefits. Just saying
@@asiseeit2041 Yes, it is likely (I too, have donated frequently) that the good feeling which follows bloodletting may well have contributed to the idea of its health-promoting qualities. Yes, it is not a question of whether or not bloodletting is healthful, but whether people in the past had any rational basis for their views of the world. Calling them "wrong" betrays a presentist arrogance.
I like how he talks about the animation video as animation because that’s all it is they can’t get a real video of earth like that
It's Bob!!!! I'm Wonderstruck! :D
This is a title to an album by a group known as Firesign Theatre.......Everything you know is wrong........ Came out in the mid 80s
Used to love firesign theater balif wack his pee pee
Dave's not here..
First albums came out as early as 1972 or earlier.
Good musicians are very similar to good scientists, they are playing with things they can never touch.
"6 million years ago, somebody but we don't know who, had an idea to change our locomotion." Correct me if I'm wrong but I'm sure it was Walt Disney.
...AND, EVERYTHING IS ENERGY. Mass is energy, light is energy, sled on a hilltop is energy, sled speeding down the hill is energy. Einstein said it, "Everything is energy." And energy warps space-time. And separate warp-space attract. We call it "gravity".
Bob knows how to deliver scientific reality in funny way.
Love him! He is a gifted speaker, I can imagine he is in high demand,
Who are the people that go to these seminars? Read books!
Rowdy Bodine I fall asleep... he kept me awake with his antics...
"We are the first species to actually change the chemistry of the atmosphere"
Cyanobacteria: "And I took offense to that"
You're right. Still, inducing the "big oxidation", cyanobacteria suffered a mass extinction event :-) Should that be a lesson?
the average temp on Earth is 17 ° C the space around d the Earth outerspace that is to say is about -270°C this difference is huge and there should be a way to exploit this differential as an energy source . conversely the perfect vaccumm of space is another potential exploit that can be tapped to make energy
the mass per volume(of space) ratio would be so small that it wouldnt really make sense to try. Theres only about 6000 atoms per cubic metre in outer space which we can use to get energy. And even with 100% efficiency it would net much less energy than is needed just to stay operational.
camicazi I disagree. we've witnessed the power a single atom can unleash . with the atom bomb . not that that's the means to the end I would exploit.
then what would you do? cause all (known) methods that convert temperature differences into other forms of energy wouldnt make sense to do in this scenario. Change in energy for lowering or heightening temperature of an atom is MUCH less than the energy from fusion/fission from the same atoms. For perspective. 1 gram of hydrogen nets about 1 gigawatt from fusion processes. but gathering 1 gram of it in space would require 5.9747022e+26 cubic meters, and this is if every single atom in space was hydrogen.
This is more than 1000 x bigger volume than the earth.
And this is for fusion, not harvesting energy from temperature difference
Do you see the problems with getting net energy from this yet?
Once man/woman work out how to create useable energy from nuclear fusion our energy problems will be solved
@@dja613x And they'll figure that out about the time flying cars are in common use...
Stromatolites changed the atmosphere too, and we should thank them for it.
Yes, and in some millions of years some strange animal will thank us for what we did, now...
But we will not be there to see it... becurse we did it 🤐😴😜
Very convincing Sir!! I was almost carried away, but please throw some light on the topic ..."Did we go to the Moon or did the Moon come to us??" Also the occults heppening in CERN arena, the largest "science or occult? laboratory".
the title should be : "Everything we are told is wrong" its a sad true
Sorry, Luis, but you fail to understand how science works. It is not about opinion but about evidence. It's about observing the universe/reality, creating hypotheses based on those observations and then testing them. No hypothesis can be proven to be true or false since we lack a 100% understanding of how the universe/reality works. We have to muddle along gathering knowledge as we go and must be prepared to toss aside information that is proven wrong through experimentation.
The title is accurate as we can't prove anything we know to be right but only proven wrong based on experimentation.
It is frustrating to not have unassailable knowledge but the scientific process (and it is a process) is the best way for us to figure out how the universe/reality works.
@@briguy677 So explain to me how when scientists followed the scientific method and their findings were 100 % accurate other scientists or theorists negated the results based only on believes and philosophical impossibilities? Im talking about the Michaelson Morley experiment negated by a theorist Einstein and inventing his relativity theory in the process. So yes , everything we are told is based only on who is in charge and who will benefit from the specific findings. Its a sad true but we have been told only what the people in power want us to know and no more.
@@luis-alvarez929 You have proven with this post that you really don't understand how science works. The Michelson-Morley experiment failed to find evidence for their predictions that there was an aether permeating space which allowed light waves to pass through the vacuum. No one, including Einstein, negated anything regarding the undertaking. In fact, it was more along the opposite lines. Michelson and Morley's failure was evidence that the theory of relativity was correct.
The scientific process wouldn't work if it was based on an argument from authority. In fact, it's the complete reverse. Scientists are constantly trying to prove one another wrong, not because they are dicks, but rather because they want to discover evidence for what is true.
By the way, the Michelson-Morley experiment has been repeated a number of times (the latest in 2006) with equipment far more fine-tuned than in the original experiment and every time it has failed to produce positive results. This continues to support Einstein's theory of relativity is most likely correct.
Briguy A lot of Theories out their that can Never be proved !
@@stuartfoster7582 Theories can't be "proved" to be "true" the point is they have yet to be proven to be wrong. The idea is to predict how/why something works and then find evidence that either proves the prediction wrong or finds evidence that upholds the prediction.. Even if a prediction holds up now doesn't mean it's true or necessarily correct as future tests or evidence could prove it wrong.
"What if Everything You Know is Wrong?" Then you'd be a member of my family!!!! "YOU'RE WRONG!!!"
haha, true
I know I'm late to the game,but really enjoyed the talk...
Everyone needs to watch and listen to this man. Everything he said is as relevant today as it was then perhaps even more so considering the events of the past two years. We as a species must come together and realize that there is no I in the human equation. There is only we. We are all in this together. It doesn't matter how you may feel about this person or that person this thing or that thing you can not truly escape it except through death. Everyone single solitary molecule is crammed into the same cart together and then rolled down the hill on this roller coaster called life. There is absolutely nothing that you can do with your bank account that is going to change that fact. Heck you can't even get off the ride. So why don't we try to make the journey a little less turbulent? And try to maintain this vessel to insure that the ones we leave behind will have a place to sit when it is their turn to go down the hill. Cause the one thing we don't want is for that cart this our roller coaster ride to stop rolling to come to the end of the track. Each of us only have one ticket to ride don't waste it. Love y'all
Be Kind Stay Strong Always Question
I like scientists, as long as they are not on an ideological crusade.
I hold the same opinion about religious people.
I like many of them I meet, just so long as they're not trying to get me to believe what they do.
If they put personal beliefs or ideas before science, then they aren't true scientists.
"In general, we look for a new law by the following process. First, we guess it. Then we compute the consequences of the guess, to see what, if this is right, if this law we guess is right, to see what it would imply and then we compare the computation results to nature, or we say compare to experiment or experience, compare it directly with observations to see if it works.
If it disagrees with experiment, it’s wrong. In that simple statement is the key to science. It doesn’t make any difference how beautiful your guess is, it doesn’t matter how smart you are who made the guess, or what his name is… If it disagrees with experiment, it’s wrong. That’s all there is to it.” -Richard Feynman
He is not a scientist. From Wikipedia; "In 1972, with no formal academic training, he began his science communication career as a demonstrator at the Ontario Science Centre, and eventually traveled to California to watch the live action of NASA's first space probes. Upon returning to Canada, he was in great demand to talk about the missions and eventually became the regular science correspondent for a number of shows"
