What if Everything You Know is Wrong: Bob McDonald at TEDxVictoria 2013 

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.

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".

@@emilofcrete ש!שששששש!

Have to disagree with know nothing.

Favorite quote is “Everything we know is only a drop worth of water and what we dont know is an ocean’s worth” -Dark

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.

Ha! And if it weren’t for them, we wouldn’t be here breathing this sweet sweet air that we do!

I spewed my drink..don't do that to me

you think maybe from passing wind

LOL Seems like the ego has perhaps taken over many scientific endeavors turning them into Quixotic exercises in the human condition

Two scientists walk into a bar/. One says a glass of CO2 thanks. The second says I'll have a glass of CO2 too thanks, drank it and died. Why?

Damn proverbial boss👍🏽👍🏽👍🏽👍🏽👍🏽

That's just the way it is once you get the answer to one question it opens up 10 more questions, so as they say why ask why.

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.

Been feeling like this too

But our ignorance is at a higher level. We do know more than we did, even though it means we now see how much we don't know.

Science advances one funeral at a time!

lol true scientists are constantly trying to disprove everything they think they know. A scientific idea (hypothesis) doesn't get to be called a theory until a) it explains nicely, a very substantial portion of the relevant information we have now, and has survived repeated experiments trying to disprove it, and b) it is "falsifiable" - i.e., it can be disproven via new information that it fails to satisfactorily explain. True scientists are the Ultimate Skeptics.

@@altareggo Well said. Also, theories have solid evidence to back them up. They aren't just ideas pulled out of someone's rear.

Scientists need to be funded, which has made science the servant of technology. Scientists take a huge risk when they challenge the status quo, safety favours the ¨Herd Instinct.¨

Jefferdaughter it is wrong

Amen .. this guys on crack .

TED talks are church for lefties

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.

The agenda you dolts are talking about is a thermometer, wake up dipshits.

"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🤯

Uh...he’s a moron. None of that was even science lol

@@growbydoing7290 why is he a moron

@@zemmig I’d suspect generations of inbreeding , alcoholism and horrible family life combined with a atrocious education system.

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?

Brainwashed not enlightened.every word was theory...not a fact spoken other than "we can't go to the moon."

Not really. Seen MUCH BETTER.

If it's crazy, it's certainly not enlightenment.

We will burn out sooner rather than later methinks.

Clever response 🤔

Those culminating approximations are glorious.

Are you sure ?

Been hangin out eith Stephon Erkel again I see.

You are totally right, unless of course, Bobs wrong. And Bob certainly has been wrong with false reports for decades.

This talk was full of fiction. All wrong

You know, More of Gods people need to come to terms THAT CIENCE IS GOD..GOD IS SCIENCE.. NOTHING IS THAT WASNT MADE BY GOD AND JESUS. ITS A FACT. EVERYTHING IS SCIENCE.

@Terrie Pehrson3 Deuteronomy 4:19 And when you look up into the sky and see the sun, moon, and stars-all the forces of heaven-don’t be seduced into worshiping them. The LORD your God gave them to all the peoples of the earth. Job 12:10 In his hand is the life of every creature and the breath of all mankind.

Worthless information.....................................

The best teachers must be themselves great students. Bob counts as both.

3 yrs ago.... Science is not important anymore. So called "Fact checking" Is more important. Sars CoV-2 is %100 politics and Zero science.

Yeah he was right about us not going to the moon too 😆

Jox

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.

@@ilikeme1234 Grant Perkins is correct! In 40 years this Bob McDonald will seem as silly as the flat earthers! Have faith that humanity will solve the problem. Not everyone is as dense as you.

Vern the great yeah, probably not. You’re confusing theories based on empirical evidence and meaningless beliefs. I’m surprised people like you are able to feed yourselves. I’d figure operating a fork would be difficult.

@@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.

Grant Perkins yeap another lost soul

Must have been a Woke crowd. After all Gates has the solution too. Depopulation! Genocide. Etc. Did it ever occur to the nincompoop ya hooz that our weather etc changes are caused by solar issues and things in our solar system which we cannot see!!! Duh. Don't be so open minded that you're filled with Bolsheviks BS.

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" '

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

Oh, there are billions upon billions, and some day we will be able to reach some of them. Spaceflight is still in it’s infancy right now.

@@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...

NOT! 🤮

Once you know nothing, then nothing can hold you back!

You know nothing jon snow😂😂

You can't also be sure that you're not sure

People have known that the Earth is round, for ages. He's just repeating modern misbeliefs

I can neither confirm or deny

Simp

??

This is the point where I stopped and thought to myself... Oh.. He's a journalist not a real scientist. The earth's atmosphere has changed radically several times before humans ever became a thing.

No it’s not true the earth has changed its own chemistry the temperature of the earth has swung over 100° in the last 45 billion years 99.99% of every animal is extinct before humans even began to stand up you could be anti-human but I won’t be

Yes, are changing the world for the better. Compare the increase in green vegetations in the past 30 years. The world is actually getting greener due to the fertilization effects of CO2.

Especially when you find out that the picture of the earth from the moon was cropped in. Modern computer programs prove it. More amazing is that a person wouldn't die of radiation poisoning in hours if they were able to get beyond low earth orbit and go past the Van Allen belt. The Blue Marble and all the rest are CGI (admitted be the creator) "because it has to be".

Its impossible to take a photo of an entire sphere

@@rd-ch1on Even from the moon, because they would have to be there to take the picture.

The “picture” they supposedly took with hand held camera is awful clear for the early cameras they had back then.

@@tiffanykoehn5948 no pollution for a start. Plus I challenge you to take a picture yourself from the same spot. Ask Elon

yes, he is an optimist, is that all you got out of the talk?

@@barbossa70 We're screwed, that's the terrible truth. Just turn on the news. Capital, profit, luxury is the dominant religion. However, a glimmer of hope must remain.

Really 6 million years is a lot. The way things are going, the boat is capable of sinking in less than 2 thousand years (the iceberg is identified but...). I still believe that we will be able to rebuild civilization after the disaster. Maybe learn from it.

No, he's the same as Bill Nye, "The Science Guy". He's a great speaker, humorous and captures your attention. But he's talking political science not true science. Read my post for my rationale.

@@rvnmedic1968 True. He's clearly a smart guy and is very charismatic, but at the end of the day he is pushing an agenda, which in this case is global warming

This man made my day. Well night since all I do is absorb information non stop. Really inspiring talk! I wish I could do something more to solve these problems. Maybe I will.

Of course the kids would have to go to the corner bar where Mr. McDonald spends most of his time.

To each entrant to his/her 6th year of education.

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.

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%...

Light has a ending/dying point darkness doesn't.. dark well always when eventually... every where light goes darkness was there first... so which ones really means INTELLIGENTS

No, with investigation.

@@blvxkgxldimperialllc1677very hard to forlorn due to construction problems.

Tiffany Poirier wish i was your student

Correct his numerous mistakes.

Very wrong

Yea I thought about the same lol.

@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.

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.

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...

thanks for making me spit out my coffee... lololol

Their death is orders of magnitude brighter, but only lasts an extremely small fraction of the lifetime of the star.

I thought the same! The statement is simply untrue. He has some good ideas but overall, its a poorly constructed.

@@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.

I guess never

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

They also tend to pick their scientists so that the discenters don't get air time.

@@MichaelWilliams-ph4ri There is a debate between flat earthers and scientists on RU-vid. It's pretty painful to watch, but shows how flat earthers (and, I would say, climate deniers) think.

I'd like, too... but with this para-science sect created by dictatorship regimes with a whole "virtual world" of fake info, it won't be easy.

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.. the wave structure of matter spaceandmotion

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.

@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.

yes

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.

@@AikenBruce I proved it for myself that the Earth is a ball. All you have to do is watch a Sunset in different places on earth.

@@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. Many people still subscribe to that ridiculous myth the Sun is a ball of gas in a vacuum - this of course is scientifically impossible.

​@@AikenBruce "Many people still subscribe to that ridiculous myth the Sun is a ball of gas in a vacuum - this of course is scientifically impossible. " can you send me a link to the academic paper disproving that Myth please?

@@checooke6583 The fact you have not heard of the plethora of science, including scientific papers and observable and repeatable experiments, proving the Earth is stationary proves what?

This guy lecturing us on science didn't know that plants produce oxygen, but otherwise it was OK...

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

Same could be said about the super volcanos that took us out of the ice age...

Plants produce oxygen??? Source please

@@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.

ok but current man made climate change is still real

Go into politics and try to change the system from within. Very hard,almost futile

Yup he’s a moron.

Like what 😂🤣

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.

Wrong

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.

Jack attack

If politicians and industrialists acknowledged/accepted/admitted the truth, then the current structures of our society (political/economic) could no longer be justified. The only way to sustain the current systems of class and wealth is to deny science and the facts of Nature. Is it a coincidence that the biggest proponents of Capitalism are rich, white men?
