To understand anything we must go beyond man's conventional mind - and that includes science itself which is limited to our logical, linear thinking process. Without restriction, we must allow our intuition, if we are to reach outside our human limitations.

I don't have to share this but I will. I witnessed an alien craft back in 2008 above Nailsworth, Gloucestershire U.K. This craft hovered and took off at such tremendous speed...it was beyond reason. Aliens are definitely here !!

"What guaranty does the knowing subject have that his models of reality reflect reality itself. Inasmuch as, in an exclusively theoretical science, the only contact that one has with reality is afforded by means of one's knowledge, the problem seems insoluble." Immanuel Kant,

As a layperson, thank you. This was excellent!

With respect to infinity, ALL possible points are legitimate centers, including the human being. So it's no wonder that we've felt like we're at the center for a long time, because on the grandest scale, we are.

I think our knowledge is like a puzzle. At a certain point the whole shows itself and everything falls into place of course, we are far from there. We just have a drop in the bucket and yet are convinced we have it almost full.

Never knew Lemaitre thought up "dark energy". I have a hunch the he considered the possibility that space itself is the base of all mass. Energy would just be a form of this space mass under massive pressure that divides it, gives it direction, and a spin. The same force that forged atoms and gravity will gain momentum despite how much energy our universe has concentrated, conserves, and radiates. I suppose the notion of considering space as an infinite area would turn off many physicists, considering Einstein's reaction, YET, here we are berthed from an infinitely dense moment.

What a beautifully delivered .. and quite frankly honest lecture! ... Plenty of food for thought :) Thank you :)

Actually the quote is from Werner Erhard decades prior, Rumsfield just repeated it during a press conference without giving credit and everyone mistakenly attributes it to him.

We are not geared for truth, we are geared for survival.

Faster than light is where the thinking mood is at.

Let us be honest the name of this program is what we can and what we cannot tell you

Looking out into space is the same as looking into a living creature or ourselves size is irrelevant.We are so limited in our knowledge,as a fish living in water.

13,559 views and no comments! "Your calculations are correct, but your physics is terrible." The majority of the universe is invisible and undetectable, except by mathematics? What if the red shift has been misinterpreted? How far in the wrong direction will cosmologists go before listening to alternative theories. The Electric Universe Theory clears so much of this up. The primary force in the universe is not gravity, but electricity.

Those of us aware of our past lives know Nature’s way ahead of cryogenics.

The anomaly of consciousness: To be possible, the laws of physics have to be able to support it. Which sounds like it must be very fundamental somewhere within the laws of physics. The physics does not stop life existing, nor intelligent life, but it does not, as we understand it, provide any reason why life, even very intelligent life, needs to be conscious.

Of all people quoting rummy, the guy should be quoting resounding truths. Not from a guy who has disdain for it.

Thank you for your lecture. I needed the review. It has helped my understanding.

The whole antimatter theory and research falls apart if one gives a tini tiny amount of mass to the photon! Let it sink in.

I wish this gentleman had not glossed over so much in this presentation. He certainly presents the consensus view, but in doing so he for instance elides the issue of how the chemicals in Darwin's pond could possibly have combined to produce DNA, and even harder, managed to code themselves for replication of proteins. He also accepts that mere processing power makes a computer superior to the human brain. He does not mention consciousness, and we have no idea how it is created. More simply, he does not mention that a machine would have to develop intention. As I put it to a friend, Big Blue did not go out for a beer and celebrate after it beat the world chess champion.

I would suspect that intelligent life would only appear to us if light from their side of space reached us in time that we are still here to observe it. However, in the vast emptiness of space, we see that there are still new stars forming. There are chances that we dismiss those as void of any life because we are observing them as they were in the past. There is no way of telling that those newly forming stars harbor planets with any life in them.

Professor Silk, there are dozens of videos on You Tube, on "How The Universe Works". I know very little about astronomy, but whenever any astronomers or astrophysicists talk or write about the Universe, I always wonder, WHY they talk so much about how the Universe works, seem to be carefully avoiding talking about the origins and the "history" of the Universe. We were being taught by them fore decades, that it was an invisible, subatomic particle which exploded for no reason at all, and out of this particle came out the mind boggling MASS of the whole Universe. Then, after being reminded, that they also teach, that before that explosion of that subatomic PARTICLE, there was absolutely NOTHING at all. Not even space, or time. So, there couldn't be any particle that exploded (With that "Big Bang", of course). So, after a while, they (no doubt, including you, Professor), started teaching, that it was NOTHING, that exploded and gave birth to this incomprehensibly huge MASS of the Universe..... To cut the long story short, they published, some time ago a map of the Universe, and you surely know about it. That got me thinking, how could they produce a map of the Universe, when the Universe is expanding already for several millions or billions of years, with the speed of a bullet, ALSO in the OPPOSITE direction to what we are rushing rushing into space. Therefore, it is undeniable FACT, that those billions upon billions or probably, rather trillions upon trillions of Galaxies with trillions of stars in each of them which we and the Hubble telescope can see in our sky above, is only a tiny fraction of the Universe, because the EQUAL number of Galaxies and stars, are expanding for millions of years already, from the point of that explosion - the "Big Bang" - in the OPPOSITE DIRECTION! And not onle that, but the same incomprehensible number of stars and Galaxies are rushing away not only in the opposite direction to oure, but in ALL DIRECTIONS, from the point of the "Big Bang", just like shrapnels from any explosions, like beams from the Sun, fireworks exploding in the midair, etc... Therefore, my question to you Professor Silk is: - Do you agree, that the Universe keeps expanding for billions of years, ALSO in the opposite direction to ours?

Lol. I think this "Unknown" saying attributed to Rumsfield actually predates his saying of it and is put in a more graceful form of prose. I am paraphrasing it here from my memory many years ago. It says: "There are things we know we know... and there are things we know we don't know which are far bigger (in quantity)... but there are things that we do no know that we don't know which is way by far the biggest."

known knowns are used by engineers for real life applications known unknowns are pursued by physicists

"There is much in the universe we will never know, and it is equally certain that we will never know all that we do not know." Nice admission by a scientist. Also, there are things we think we know but ain't so. So keep making things up, so theoretical physicists can stay on the gravy train until the end of "spacetime"!

Thank you for sharing this presentation.

Static-> metastable-> poised for change.., same actual mechanism that is the visible cross-sectioning navigation mapping of the holographic image projection drawing, Observable Universe.

Extraordinary. Thank you for such an interesting presentation!

Know yourself to attain an eternal happiness; trying to know beyond yourself only to suffer; trying to know the unthinkable to drive you crazy

The reality is that we have visitors from we know not where, making use of physics we know not of, running a mok around our planet!

There is no physical life out there . There is heaven a spiritual realm . The universe was made for man with LOVE .

Man is central because God intended it this way, lets not make this anymore confusing then this has to be. We're here on earth and we should concentrate on it and not whats out in space. We have many issues we need to address on our tiny home. If we dont address them then really all this other stuff your taking about will NOT matter....

No life = no universe ! Why ? Who or what would know it exists ! So..... Is there a Supreme ‘thing’ which we now call ‘God’ ? Who knows .... (Think it through ! )

Uninteresting: it used to be "We know this much, the rest is God." Now it's ,"We know this much (4%) and the rest is Dark Stuff." The scientific mind is very useful, but quite incapable of seeing the whole picture. Max Planck realised that matter is derivative of consciousness -- factor that in, and the picture is suddenly, radically different. This gentleman is making exquisite measurements of distant galaxies, while holding the current view that we cannot measure anything without changing it. Yet on that framework the theories are knitted. The scientist suppresses his intuition, The priest suppresses his rationality. Neither have an interest in the metaphysical world in which we live.

i loved this lecture. the lack of hubris is so attractive. when scientists deny that weaknesses in their exist in their theories one is instantly suspicious that they are wrong. knowledge cannot evolve without doubt and certainty is a result of uncertainty. Shame he added the exoplanets though. Looking for planets like earth for signs of life is a upside down strategy. What is needed is discover how well basic life forms can manage in hostile environments. So, take Venus, is it really impossible for life to succeed there? if you don't try cannot know this. You need to simulate the conditions and then try and find life forms that can exist there. Find what life can survive then look for planets. There was algae, fungy, and bacteria living on the outside of the ISS (origin earth). I know, exoplanets are hyped up and are fun research getting good grants,

The professor is pure electricity on stage! Reminds me of zeppelin at Madison Square garden in 68!

The known unknown of whether I will continue watching this video has just become a known known, and the answer is no, no, no[n]

How much do we understand? Virtually nothing. Socrates taught us that 2500 years ago.

The universe with evil but no God doesn’t make sense. Therefore the universe with evil proves the existence of God.

I am certain I am the most important person in the world. Everyone else believes the same, they are the most important person in life. I am infinitely significant to myself and infinitely insignificant to the Universe. Every bird believes they are at the center. Are the birds correct?

Isn't it obvious that we don't even know that we know nothing.

By the end of his life Hubble thought red shift might be caused by 1 to 2% movement away and the rest to other causes. Halton Arp was shamefully ignored when he contested the idea that red shift showed a rapidly expanding universe. He also predicted that adherence to this idea would result in larger and more distant objects being discovered that would eventually defy credibility....which we have seen with 'huge objects far far away'. Red shift is likely due to the age of bodies rather than their distance and recessional speed.

He made some false statements. He said Venus was less hot than Mercury and that Mars had no water and no Atmosphere.

49:08 how would you make the moon rotate to see an Earth rise?

Why reiterate speculation after speculation when there's no knowledge currently available? As far as I know, even the creation of a cell (and its predecessors) is largely a mystery.

いろいろ教えてくれてありがとうございます。　感謝します。

Knowledge: The more we know ,the more we found out we don't know anything or so little. With time we forgot the knowledge, this is why computers exist, I guess..

Can't take seriously anyone who thinks that no non-human animals have consciousness, or that you can see earth rise from the moon

Distance of exoplanet from it's host sun, depends on many factors...... size of its star, temperature output, radiation output, magnetic field, etc..... as such, the exoplanet can be further from a hotter sun, or vice-versa. This also increases potential sustenance for life, or lifeforms.

"We can arrange the atoms the way we want, the very atoms all the way down!" That sounds like alchemy to me. I thought Richard Feynmann was supposed to be brilliant.

For up to date news on the cosmos' mysteries study Suspicious Observaors on KZfaq & use the links to various Web sites they provide.

Have you read the result of the American military’s report on the redoing of the Michelson Morley experiment? Also have you stopped attributing the unexplainable on Aliens yet ?

can't see the earth rise on the moon because of tidal lock, all you can do is watch the earth go round and round every 24 hours, and from day to night to day every 28 days.

He has to move along a little faster and come up with something new. How did he achieve this position?

Stars being born is an unproved theory. No one has ever seen a star forming.

The view from a narrow magnified lens on earth has a limited field of view, however, when looking at the perimeters of our solar system, why to we see fixed orbit structures.

Rumsfeld's comment =, what is the shape of the universe, only asked from the angle of attack of evil.

Drake Equation: Assumes each civilisation is based around its own star and has to evolve from inorganic thru bacteria to multicellular to intelligent to technological. But this misses the more likely possibility of persistent civilisations spread across countless star system and not even necessarily living on planets eg they may simply live in space. We after all envisage supporting trillions of people in O'Neil Cylinders in the future, enormously more than can live on a planet, with all its attendant problems of the gravity well and the risk of comet hits etc.

This talk ignores so much fact not in evidence and evidence not among the facts. The two most important evidences are information and intelligence. These two things are not a property of matter, energy, chemistry, or the natural ordering of matter on an atomic, molecular, or galactic scale.

First half of the presentation can be safely omitted, but is there anything new in the second part, really??????

One delude's themselves when you suppose the development a complex system is fathomable by means of self assembly. Given enough time anything is possible you say? Time is your ENEMY in organic synthesis. Let's be realistic here. The simplest of cells are more complex than we have the capacity to understand. In the last 60 yrs every field of technology has flourished at exponential rates and is compounding by multiple orders of magnitude. Origin of life research since the Miller Urey experiment has gotten nowhere. No advances have been made. Actually when you take into consideration the complexity we now see in even the simplest of cells, it would be safe to say that our newfound understanding puts us even further away. Moreover, there is no mechanism even PROPOSED by which the self assembly of complex organisms may construct. If someone tells you there is, it's a lie. The human genome project has exhibited a level of precision yet displays such deception you begin to understand that somehow, this lie that biology has a mechanism to abiogenesis is a desperate attempt to hold the public to a narrative of deception. Upon mapping of the protein coding region of our DNA with it's some 20,000 sequences, we have been deemed 99.5% identical to the ape. (since been lowered to about 98%). This is a true statement. Proponents of origin through common decent rejoiced. We had been vindicated. Settled science! But wait. Nobody told you that the coding region of our DNA only accounts for 1% -1.5% of our ENTIRE DNA! Now the difference is in the remainder, once called junk DNA , now called the intergenic region is believed to be completely functional with a regulatory system matrix that is far beyond our capacity of understanding. Did this surprise you?

Man is the measure of all things.

I am puzzled. How are dark matter and dark energy distinguished? What is gravity actually? Is dark energy anti gravity actually? What are at the outer borders of the present Universe? or Is the Universe a mathamatical construct with limits? What is the Universe expanding into? Is it proper to call the big bang a singularity?

"In the beginning (time), God made the heavens (space) and the earth (matter) Gen 1:1. As scientists we love the details, but do we really know much more than the ancient rabbis?

what we perceive as expansion of the universe is nothing more than the material universe riding the peaks and troughs of a vast cosmic sea which we cant detect

OMG, that's the most interesting suit he's wearing! :)

You can't forget what you don't know, but you can remember what you do know. If you knew what you don't know, could you forget it? I knew the answer but I can't remember.

Physicist: " BuT wHy?" Universe: "THAT'S ENOUGH!"

You don't think so? Well now I know I am done listening. I have seen animals show emotion and recognize themselves in a mirror. Intelligence?

Let's begin with the fact that no earth probe has exited the suns field of affect. Outside of the vacuum caused by the movement of the sun in the unknown property of space, the question is, do the observable affects of a vacuum exist in deep space.

The total sum of human knowledge compared to what is here and out there yet to learn and know, is somewhat comparable to a yocto particle of wood afloat in earth s oceans. A good igniter of fresher learning towards more and better knowledge depends on ditching some bad ideas like the big bang which has lately become a limiter, the universe is much bigger and ancient than people have been led to believe.

Two frogs chose to continue live in a well they were born to, one day, started a conversation about “the limit of our knowledge”. There were less incentive for them to venture to the “outer well” or another well in fear of can’t find food out side or wind up on a dinner plate for some predators. The next and the rest of days they resume their conversation from what they have left off a day before. Emmanuel Velikovsky, Electric Universe and Thunderbolt Project welcomes you to their “well”. Join us on KZfaq. Followers to a practical world lives a fuller intellectual life than those live in fantasy world. This universe, from microcosmic (atom) to macrocosmic, is compose of two forces (1) electric and (2) gravity. Electric force is 4.1556^42 times stronger than gravity. Modeling our universe without electric force is as good as living in a fantasy world. Newton and Kepler both knew gravity is instantaneous but Einstein’s administration (human god) decided to legislate that nothing can go faster than light speed including gravity, is incorrect. If that is true earth will not hold a constant radius around solar and will soon wonder off into the cold dark space and we all died of cold.

Donald Rumsfield misquoted right at the beginning

germany solar energy constituent is only 7% not 40%. great overview talk otherwise!

How can we determine the universal physics of what we see from the suns vacuum in space. To determine the physics of outside the vacuum, we have to be there.

And so the limits of are knowledge are....?

Has anyone looked at the complexity, such as the compression of a spring, being dark matter.

Cryogenics will never work the way you do it . The reason is that as long as there is a small amount of water in the organism , when turning into ice , the volume will increase & the cells explode , killing you instantely ...

But what about bright energy and bright matter which are invisible and undetectable by all known methods, this bright matter and energy are the polar opposites of dark matter and energy and cancel out the effects of both, therefore another explanation is needed, this time try finding a scientific explanation instead of invoking magical undetectable fictitious entities.

Sure the universe is expanding? And if so where is it expanding into? If the space itself is expanding all should be expanding with it and we could not notice that unless being outside of it like when we see a balloon being inflated into an external space. If universe has a gravitational potential maybe very distant galaxies appear reddish because of their light being stretched during the travel to us and not because of increased recession velocity.

Nicely explaination. Invisible is difficult to see

the context of the universe is spiritual consciousness which flows from the top down creating physicality...as a secondary event a for detailed starting point leading to enlightenment.

why do physist think that the begining actually had the same laws.this handicaps them

I just want to thank you for starting off with a quote from Donald Rumsfield. I had no idea where you were going in this lecture but the headline piqued my interest. As soon as you began quoting Rumsfield, I knew I had seen enough. Bye.

It's ironic and funny when you see science speaking about beliefs. I thought beliefs was domain of religion and not science. There was at least an acknowledgement here that we don't know unlike many well known ardent proponents of science which are way more emphatic than deserved. One of the most fascinating aspects to watch out for is, is consciousness and underlying or emergent phinominon? Now technology is far enough advanced to reveal the results in the next decade or two. It will help to shed light on science and where it stands.

This lecturers point of vector is from the 19th century.

Chaos theory is about limits, however their are similarities.

we do seem to be at the center of the qauntom universe .we alone doctate if its a particle or wave even both .simply by observation.

Damage control because, as is stated on the Steve jackson card game, ''The flat earthers know something''.

I'm all for integrating with AI, because we can confirm detection of unknowns by using the other areas of the Electromagnetic spectrum, via the AI's optical capabilities. Now- imagine that integrated with our brain... Being able to see that which we currently cannot see... thus; Knowing that which we currently do not know...

My mind goes into some funky spaces sometimes

Looking for the perfected mechanist (incorrect) theories for life and the universe. Best I have seen, really. For actual reality try Rupert Sheldrake.

Good!

Earth like planets in the milky way ? May be 1000 . Advanced civilisations ? May be 10 .

One major problem that needs to be taken into account in interstellar travel are the great speeds and distances involved. Hence, the probability of colliding with one of the myriad of rocks that are flying around out there would be too high to consider such travelin the physical sense a realistic possibility. This does not rule out the possibility of non-physical travel

Maybe we are unaware that we know everything

@21:32 "Mercury for example, like an oven" Then "Venus a bit further out, a bit less hot". Actually Venus is hotter than Mercury. Sorry that was a bit picky, it's been a good set of talks.

maybe the idea of something being made of something is too rudimentary and solipsistic

In’t GOD great

The first 3 Min's of creation? IT appears that the Doppler effect can be measured on bodies of the same age. Is Doppler an effect of distance or age?
