- Опубликовано: 21 ноя 2024
- The question "Why is there something rather than nothing?" has been asked for millennia by people who argue for a creator of our universe. Taking a trip back to the beginning of the beginning and the end of the end-and reviewing the remarkable developments in cosmology and particle physics over the past 40 years that have revolutionized our picture of the universe-Lawrence M. Krauss explores the discoveries that have revolutionized our understanding of both nothing and something. It has become clear that not only can our universe naturally arise from nothing, without supernatural shenanigans, but that it probably did.
12:50 The lecture starts
Krauss really didn't like that long introduction. Lol
Thank you.
@@droidnick Right! I don't know how many times I've gone to a lecture and the person doing the introduction just can't shut up. There's something about a hot mic!
I'm like, who are these people talking, not saying anything. I suppose there's a reason I don't know who they are and won't remember them if i see them again.
Thank you for the hint...
I have no education in this field, other than my curiosity and love of all things science related. Yet I feel like I can grasp what he’s saying (I’m most likely not, lol). That’s the mark of an amazing communicator. What a gift to humanity this man, and people like him are.
The joker
@stoyanfurdzhev When he passes, we can put his body in Amber on display.
"Here is the hominid surname Krauss..a primate who believed he had the answers to The Nothing"
Read the gospel of John, Mathew and the Bible, the Holy Spirit is the ultimate communicator,and loves us and want to co- habbitate with us.
@@SuperReznative I will not read your fantasy book, thanks. Stop trying to shove your bullshit down everybody else's throat, religion's time passed a century ago.

Never understood the point of these stupid intros.
@@davidchou1675 It's just narcissism. The people that insist on doing long-winded introductions want to have their own moment in the spotlight, even though it contributes nothing. But hey.. we live in the information age, which makes things skip-able. As the good prof says, it's great to live in a very special time.
Very much appreciate this..
There intro was ridicules ;)
I couldn't agree with you more, Science gives us the opportunity to Ask questions, hows instead of why's? Questions shouldn't penalize anyone, it's the only way to drive progress. ' Let's enjoy our brief time in the sun '. Thank you Lawrence Krauss.
:)
Have watched this lecture repeatedly each time I understand a bit more-thank you for making this possible....
Could of saved yourself some time and read the book
@@Cuckold_Cockles think this foray works just fine plus it is nice to see different places!
nothing to understand. he re-defines a word to create an ambiguous theory that doesnt hold. Nothing is nothing, he's trying to make it 'something'.
@@dadush4 stop trying to sound smart. U just sound like an idiot...everyone thinks that not just me.
@@dadush4 And all you have is a definition: "if something come from X, then X is not nothing". The point is if you were told 50 years ago that the net mass and energy of the entire Universe may be zero you would have said that's ridiculous.
I love listening to Lawrence Krauss speak. I learned a lot just listening to this lecture.... fascinating things I never thought to ask.
It has now been more than a decade since I first heard these remarkable ideas. Since then, it has become clear that these ideas exist within an an enormous realm of unknown unknowns.
The universe is unimaginable vast in its expanse, as well is in the minutiae of its detail. The consequent reality is that there is much that about reality where we cannot even imagine the appropriate questions.
The ideas presented in this video are certainly fascinating speculations. And these ideas give us some ideas of what may possibly be going on…. Similar in some ways to string theory. But ultimately, we must accept that there is much about reality that we will never know. And even that there is likely much about reality about which we will not even begin to meaningfully understand what we do not know. Ie the potential multiverse, or the origin of the Big Bang.
Imo, a singular importance of this lecture is to help us start to comprehend and accept that our ignorance is as vast as the universe itself
Yes ,the Bible is God's living Word for us ,as It speeks to life itself & the soul.which is even deeper than comprending sciece, theory,etc. Ther is power in the name of ( resurrected)Jesus

The illustration of the universe expanding from no particular center point (it depends on where you're standing) in the 19th minute-ish was really helpful.
What a remarkable character. Love Dr. Krauss.
that kraus want only to talk, he dont know the real thing. The nothing is not in the quantum realm.
@@EraldBuneci Go tell that to your "god" bud.
Cosmology is where its at! This century will lay the foundation for the star children of the future to travel the universe :)
Watching this lecture is like watching Doctor Who. It's so brilliant. "And that's the first clue nothing is interesting."
Oh please!😅
Except dr who sucks
@@ChillAssTurtle so you didn't give an example of who or what you find interesting. Doing so would give some random twat on the internet a chance to take a shot at you.
The interesting thing that the year is 2022 and i find this lecture and fell in love for this Dr.
That's because he's an actual physicist who understands not only the equations but the implications of the mathematics to reality as well.
*for or *on reality
Grandiose claim considering humans know 4% about the universe (probably way less)
Brilliant absolutely brilliant. Krauss is one of the best science communicators of all time.
Thank-you for uploading this;I don't concur with all of Dr.Krauss's presentations,but I do embrace and appreciate his scholarship.His objectivity is quite impressive!
Ok, but bear in mind that you can only disagree about a conjecture, not about a fact.
There are no facts
Although I didn't understand even 1% of his lecture I very much appreciate that people like Lawrence seem to understand these concepts and can draw conclusion from them. Amazing.
😅
He is a fool . Don't "worship him" .
Lol for him there is something in nothing anyways..
It's hard to understand because you assume he is not a bullshitter. Once you understand he loves the sound of his own voice and will say anything for attention, you begin to see what's nonsense.
The greatest lecture ever told
With humour the concepts were digestible. Enjoyed this lecture.
Love this. This explanation is of different level.
How about this level?
Fun Fact known 1400 years ago...
We built the universe with ˹great˺ might, and We are certainly expanding ˹it˺. Quran 51:47
LMK's faith is astounding!
Laurence is at 12:43
He does admit that there are 'things' we still don't understand. He, therefore, is giving his hypothesis on the nature of reality. For me, consciousness is everything. Without it, we wouldn't be able to attempt to solve the phenomemon which seek to extinguish it.
The statement that consciousness is everything is an epistemological nightmare. Justification? Evidence? Faith? It is an absolutist statement. And absolutes about "everything" are non falsifiable. You might as well say everything is god. It carries about the same weight. Or you might want to say that consciousness is god. Either way, it doesn't stand. But it's a nice sleight of hand trick. Everyone's doing it. They are making claims that subjective experience is objective reality. And it's so subjective that we can't know anything about objective reality. Circular argument.
"Any explanation of consciousness in terms of physical processes or algorithms is ultimately doomed. Some people simply don't grasp the problem: you can't explain the subjective via objective means. Physical processes, no matter how complex, have objective properties and that's all. You can't throw a bunch of objective matter, forces, and fields together and declare that the invisible subjective magically emerges. There's no way to get there from here. Subjective properties are just not in the language of our basic physics and I don't see that changing any time soon."
All this is is an argument from incredulity.
Consciousness is tied to the brain. We literally have no evidence to even suggest otherwise.
Consciousness is a process. Its not everything.
Although, it's not a complete individual being, this person is AMAZING!!!
Who?
Starting from nothing can generate platforms and anchors from which to start! THANK YOU!
Identity can easily be turned into a endless subject and can be detailed and used with whichever intentions: to mention this word in French causes passionate debate since the concept 'generation identitaire' is a far right concept which fits between the parameters of a Nation and extreme cultural conservatism. It takes genuine education and nformation to hatch out of this description : individually we may have to realise that to be selfish does not have to be purely self orientated but to value and appreciate the same egoism in others as a great contributor to win win situations. The paternalist colonialist conception of charity where we expect the receiver of donations to have the same tastes as us is old fashioned and ineffective. To encourage foreigners in a coercive 'package' that includes their own Culture, while just expecting respect in return, is more again like mentioning win win situations.
Look at you and your agenda.
what the fuck! .... like WHAT THE FUCK does that have ANYTHING to do with the video you schizophrenic whackjob?
In addition to science I loved the punching down humour. He spared no one, philosophers, astronomers, biologist, couple of nobel laureates, experimental physicist, lawyers, graduate students.
And the republican party. He missed the Democrats (:-)
And theists.
@@deancamf That's prolly because general intelligence, scientifically literacy, critical thinking skills, level of education, etc. all positively correlate with liberalism. A dumb person can choose any ideology or party for dumb reasons, so inevitably there will be dumb democrats or republicans. However, smarter people tend to be liberal in a direct relationship that accelerates based on how smart they are.
For example, ~98.7% of all astrophysicists consider themselves liberal. That's not a coincidence or magic.
Republicans who noticed this trend tell themselves that schooling and college are just liberal indoctrination camps (despite there being no federally mandated curriculum, and a lot of control of curriculum coming from individual teachers). Even under that explanation, they fail to recognize many of those fields don't overlap with political issues:
Learning advanced math, special and general relativity, chemistry, quantum mechanics, fluid dynamics, orbital mechanics, spectroscopy, etc. are relevant fields to astrophysics. Gaining the skills to determine the rate that Hawking radiation is evaporating a black hole, or modeling the collapse of electrons into protons to create neutron stars, aren't the kinds of things taught in classes that talk about things like gun control, abortion, immigration, taxes.
Where does religion fit in
Even more respect for his shout out to Hitchens. Miss him now more than ever.

@@evanbarker6168 THAT statement will require a bit of explaining, as on the face of it, it seems ludicrous...
@@toAdmiller I think if you have worked with physicists doing phd or Dphil, you will find a lot of them to be arrogant
@@vishwasshankar3929 Oh I wouldn't doubt that for a moment...increased knowledge does tend to breed increased arrogance in the species, definitely an arguable trend in Homo sapiens sapiens.
Fortunately, science (especially "hard" sciences like physics) has built-in filters for such arrogance when it comes to the actual validity of the findings: peer review, reproducibility, functionality within other science disciplines, etc.
Ultimately, the arrogance of the individual researcher is merely something to be withstood/tolerated while in their presence, rather than something that actually taints the quality of their science.
My physics suggestions, challenges a lot of present ideas. But they are built on what we know now.
The following is a list of facts about photons, that physicists already accept: but that will still challenge most readers.
The list also contains two items that I suggest are accurate, but are not accepted by physicists.
Read the list and find the two of mine out of the twelve listed.
There are clues at the end to help.
HERE GOES:
Photons can create electrons and positrons in pair conversion (Energy can make mass).
Electrons and positrons annihilate into photons or energy.
(Mass can annihilate into pure energy.)
Photons are outside of space.
Photons are outside of time.
Photons are all in a single point.
Photons may be eternal.
Photons were the singularity that began the Big Bang.
Photons can make all the particles in the standard model.
Virtual Photons pop in and out of a vacuum, and are responsible for the Casimir Effect.
A photon can be in a superposition of two or more states.
Two photons that are entangled remain connected, no matter the distance between them.
Photons, electrons, and positrons are all different versions of the same thing.
CLUES:
One of the things that you really have to realize is the speed of light is very, very special. It's not just simply a speed of something moving through space. As you go faster and faster and closer to the speed of light, time itself begins to slow down. And space begins to contract. As you go close to the speed of light, the entire universe becomes smaller and smaller until it basically just becomes a single point when you're going at the speed of light. And time, as you go closer to the speed of light, gets slower and slower until basically time is a single point at the speed of light.
Light does not experience space or time. It's not just a speed going through something. All of the universe shifts around this constant, the speed of light. Time and space itself stop when you go that speed. Michelle Thaller.
This from Wikipedia article Matter Creation:
It is possible to create all fundamental particles in the standard model, including quarks, leptons and bosons using photons of varying energies above some minimum threshold, whether directly (by pair production), or by decay of the intermediate particle (such as a W− boson decaying to form an electron and an electron-antineutrino).
By studying ancient light radiated shortly after the big bang, a physicist has calculated the minimum lifetime of photons, showing that they must live for at least one billion billion years, if not forever. Scientific American.
The ANSWER
The two items that are not yet accepted by physicists are,
1 Photons were the singularity that began the Big Bang
2 Photons, electrons, and positrons are all different forms of the same thing.
Summary
Here are the key components of all my physics posts.
Photons are eternal and outside of time and distance.
The singularity of photons began the Big Bang.
Photons created electron positron pairs in the Big Bang.
These electrons and positrons made the elementary particles which in turn made the atoms.
Photons, electrons, and positrons, are all different versions of the same thing.
The energy of the universe comes from photons converting to electron positron pairs, or electrons and positrons converting to photons.
The force from the Big Bang singularity was photons, dark energy, or anti gravity.
The force from acceleration is anti gravity, not gravity.
The nothing isn’t nothing actually, it’s vaccum energy and quantum fluctuations
Rabeet. Tell that to evangelics!
HoldTheEarth idk how that relates to evangelics (jbtw if you’re considering I’m one, I’m not.)
Rabeet. It’s related to evangelics in a negative way. They simply deny your statement about the “nothing”.
@@desiderata8811 yeah I've come to find that myself that it's okay for God to just always have existed but everything else needs creator
yeah but i think he's explaining how matter can appear from nothing.
Unless you want your ears to fall off, I'd suggest jumping straight to 12:30
If "nothing" is unstable, I wonder if there are actual or theoretical parts of the universe that are so empty they may be considered as "nothing". Would such places be prone to burping out matter and anti-matter, a local big bang?
There is nowhere that man has looked where he has found "nothing", even in deep space in the emptiest vacuums imaginable, there's always "something".
Finte and infinite are the extremes of nothing.
The vacuum is never empty
@@albertclarke2826 The concept of nothing in itself is nonsensical. Try to imagine nothing. You can't do this! Because, when you do imagine nothing, you imagine something. Therefore, the concept of nothing of QM is no more false than the common concept of it.
Yes, and no. In eternal inflation, only the parts that are inflating rapidly can "slow down" (ie tunnel to a smaller vacuum energy) and thus form energy/matter into a stable universe. As all the parts in OUR universe are already at a lower vacuum energy, this wouldn't happen anywhere in our universe. In other models, yes it's possible. But really that could happen anywhere, it doesn't actually need to be empty, it's just that its so improbable it likely won't happen in the lifetime of our universe. Luckily, after the end of the universe (ie heat death), it doesn't matter if something takes a second or trillion trillion trillion years, so even though its improbable it could still happen, we just won't be around to see it.
The best way i know how of picturing absolute nothing, is trying to remember the time before you were born. Then i realize the universe came from this and my mind blows a little bit.
only it didnt, there was always something, anyone who thinks the universe came into existence from "not anything" which is the real definition of nothing isnt being honest with themselves/
@@ceceroxy2227 imagine you are born and your consciousness is given to you. your ability to perceive came from literally nothing. so as did the universe in as sense
The best way to imagine "nothing" is to not imagine anything, but if you absolutely must imagine then try imagining 'what rocks dream about'. Krause, and his ilk always equivocate on nothing. They call 'something' 'nothing' from one side of their mouths, all the while proving something isn't nothing out of the other. Without telling you that's what they are doing of course. One wonders if they actually know it themselves, which would be tragic enough, but still worse yet, I shudder to think if they know that's what they are doing and aren't telling you...well that would be diabolical. A little critical thinking wouldn't hurt these science geeks any. But it would be especially useful for the sycophants that sprinkle their paths with flower petals.
One thing I can't get over is why the laws of quantum mechanics don't count as something. Where do they come from, how do they form? It's not logical to say they just come into being because there has to be a reason, whether accidental or otherwise, that the universe began. You can't say it arose from nothing and explain it with quantum mechanics but then say the laws aren't necessary.
Yeah, I don't quite get this either. Just because we can't physically detect it right now doesn't mean it doesn't exist, or means it's "nothing", because if it were nothing, it wouldn't be there in the first place. Nothing is absence, which isn't what he was describing.
1000 years ago, we couldn't physically detect atoms, but does that mean they counted as "nothing"? Of course not, and it's the same here. I hope one day we can understand quantum mechanics in the same way we understand atoms. =]
***** You seem to be stumbling on a linguistic hurdle as opposed to a conceptual one. I am confident the title "A Universe from Nothing" is a reference to, (and a slightly sarcastic dig at) the theist's willfully ignorant question; How can the universe come from nothing, for no reason and without a creator?
Krauss is quite explicit in explaining that the colloquial understanding of 'nothing', is actually 'something'! It is from that 'something' (formerly referred to as 'nothing') that he then continues to define the mechanisms involved in the process.
He is also explicit in his unconceited disclaimer, that not everything is fully understood yet and that further research will be ongoing to supplement the unknown with a goal to fully comprehend this complex and fascinating subject.
I hope this clears up some of your confusion :-)
I've read his book and watched numerous lectures and presentations he's given on this subject and assuming my listening skills and reading comprehension are still good, I think I'm hearing him correctly. He does poke a lot of fun at theologians but "something from nothing" is not a sarcastic dig.
Nick B I don't understand where you are getting confused. Perhaps you have just have a blind spot on this subject arising from preconceived definitions or concepts.
I offered Bethany a perfectly reasonable explanation as to the choice of title, that you appear to be referencing in your latest comment. However, despite seeming to provide a collaborating argument... "He does poke a lot of fun at theologians"; you then dismiss the idea of such an act, completely out of hand, for no particular reason stated.
Note, that I did not say with any authority why I was confident of my proposal, but you state outright that... "something from nothing" is not a sarcastic dig. On what grounds (other than assumption) do you make this claim?
On what grounds? Words, maybe? Like I said, which clearly you missed, I've watched numerous interviews, lectures, presentations and have read some of his work. I'm not going to write an essay on "what my grounds are for this claim". He means what he says, it's not a figure of speech. Do you even know anything about physics? And stop trying to sound smart "doctor".
That universe within each us concerns me much more. As Thoreau implored --
"Explore within. That's what requires the eye and the nerve".
He was wrong.
Nice PHILOSOPHY you have there, Son.
It'd be a shame if someone had to test it with physics.
@@AirwavesEnglish science can't prove that anyone else exists, except you. it's not the be all end all
This Krauss guy really takes flat earth to a whole new level. "The whole UNIVERSE is flat!"
I disagree with a good amount of what he says but he might be correct. I don't think the universe is space itself, what we think of as galaxies are actually universe's each with its own singularity/big bang. I think a vacuum means having no depth, our universe/galaxy is a region of space with finte length width and no depth expect at the black hole . I'm writing in short hand.

^^^ Typical of people who value intuition-based beliefs more than they value evidence-based beliefs. If they can't understand it, it's easier for them to assume it's not true. Let's ignore what we've discovered about particles and anti-particles constantly popping in an out of existence, or more abstractly, how a "0" can spontaneously split into "-1" and "+1" before recombining an annihilating back into zero (unless some force intervenes to keep matter and anti-matter particles separated).
It's both funny and disheartening to see people make up analogies to describe concepts they don't understand, and then genuinely believe that their analogies are valid. Planks of wood don't pop into and out of existence, and there is no force that pulling those planks into the stable configuration of a house. If it did work that way, it *would* be very plausible for a house to build itself.
There is so much comments like "I believe in God, so you are wrong about everything you said I don't understand, I am so much smarter than you". So stupid.
I like how he ascribed emotions and intelligence to the universe. Sounds like a theist to me.
It's just funny
Is the introduction long enough? Jesus let’s get the show on the road Beavis!!
A simple equation can explain creation from Nothingness: if Nothingness = 0, and 0 = +1 and -1, then from Nothingness
can arise a (+1) universe and a (-1) universe. The (+1) universe being the 5% universe we live in, and the (-1) universe representing the other 95% which represents dark energy and dark matter. Or putting it in terms of credits and debits: our universe can only exist if it is paid for by an anti-universe. In nature, there is no free lunch. Think of our universe as a blend of of 2 types of Swiss cheese: all wound around together with the holes representing Worm Holes where there is no energy, matter, and no Higgs field. Completely empty space that separates our universe from its anti-universe component. A place where space craft can exceed Warp 10 and beyond. And thus allow quick traveling time to other galaxies. No Higgs Field = no resistance = unlimited acceleration.
However, in order to drive the nothingness into its something and anti-something component, there must be a slight amount of asymmetry. And over 13.8 billion years this would explain the huge disparity in asymmetry and hence the exaggerated ratio.
Beauty is often perceived as complete symmetry but when it comes to creation there must be asymmetry. Otherwise things will simply neutralize each other. In fact, evolution whether its atoms, biological systems, or the universe itself all depends on slight differences that drive things forward. Without which there would be no change. And all that is needed is just a slight misalignment or push for a process to move forward.
For those that are familiar with the Chaos Theory: can the flapping of a butterfly's wings in Brazil cause a tornado in Texas.
This allegorical representation is found everywhere in nature including quantum mechanics, also known as quantum fluctuations. It is simply randomness. No Gods, Devils, scary Demons needed. Or if you need to believe in a God System,
then why not believe believe in the following Gods:
1. God of Nothingness - which gives rise to a universe and its anti-universe component ( 0 = +1 -1).
2. God of Randomness - Mother Nature (as evident by Brownian motion).
3. God of Time - over time anything can happen ( evident by probability equations that are time dependent).
BTW: in his equation on the force of gravity, it should be divided by "r squared" rather than "r". Obviously a typo.
In reference to: "r squared" rather than "r". It's the formula located at 46:39. Anytime there is gravity and electromagnetism, the inverse square law must be applied. But yet the equation is measuring energy and since force acting over a distance is energy, then distance must be included in the numerator which then cancels out the distance squared in the denominator leaving only "r". So therefore the equation without "r squared" in the denominator is correct as in stands.
so in the end he clearly mentions that with the passage of time things become UNobservable, therefore I would say that it is possible there are things from the past that can no longer be observable wich could have been used to prove to the expected extent some believes that people now have.
Wait - is it just me or in this presentation, does Krauss kind-of gloss over the theory of the multiverse and assume that it is almost fact, without pointing out flaws? Albeit, he does caveat with saying, "may," "possibly," but his overall tone seems to imply that it's fact (my opinion, obviously). One thing that worries me is that even if we accept as fact that there are an infinite number of universes, that doesn't guarantee one like ours. Take even numbers. There are an infinite number of them. Unless I'm mistaken (I'm no mathematician) you won't ever find a single odd number in an infinite string of even numbers. My caveat: I say this from a position of ignorance, not being a physicist, etc.
Also, the irony is thick: Krauss criticizes what he calls "cosmic hubris" (meaning theists are silly at best) without recognizing the hubris of his own arguments.
Multiverse hypothesis is very popular in Scifi. Its one of those things which is either true or not. A Russian mathematician in the early 1990's published a paper in Physics Today and did the lecture circuit on the probability of 2D windows between universes, which being 2D you could see through but not go through, and had to be viewed from the correct location and angle. He provided math as his proof, but offered no means to test it in reality, not even the basic start of a physical test so I expect it was really just nonsense that got him out of Russia and invited to the better cocktail parties and lunches.
If you buy into how matter is created, the Big Bang may still be happening 13 billion years after it started for us, in quite a few universes between us and them. That's a lot of potential universes to visit, particularly since we have no idea when one universe breaks off from the big bang and another one separately spawns, repeating endlessly. An infinitely expanding number of universes, each of which eventually dies of heat death someday. 20-30 billion years later, probably (also a heavily debated point with very fuzzy inaccuracy).
If we could skip from this one to newer universes, and they have the same physical constants as this one, we might survive there too, however that particular detail is far less likely. The big constants for electromagnetism could have different values and we'd explode or implode or dissolve if we crossed, at the subatomic level. What if the strong force (keeping atoms together) is weaker? That whole universe would be subatomic plasma with no real atoms at all, thus no chemistry.
I know of no provable and repeatable evidence suggesting the popular Schoedingers Cat division of universes next door every instant from quantum variation, so popular in scifi, has any truth to it at all. So going to another universe with all the same people and one tiny difference is pretty much fantasy. A great and verdant fantasy for Scifi authors, but not factual or real science. I spent a decade learning this stuff and figuring out how to differentiate between the Cocktail Party Lecture Circuit scammer physicists from the ones that do actual experiments and always look tired and depressed. I lived near Livermore Labs for 8 years, you see. You end up with some interesting friends there.
I'm really interested in what others have to say.
Tc McCarthy The Multiverse is simply an axiom at this point, much like Einsteins C constant. And yes you are right, having a infinite number of universes doesnt guarantee one like ours, however we are here so we know their is one. However just because the probability is slim in the hypothesis doesnt mean it isnt impossible. No one knows if the multiverse is real for sure, however there are many factors, like our physical constants being so finally tuned and dark matter/energy, etc..., that are directing us to the belief that if the universe is random and our laws of physics are random than it would be highly improbable that if there was one universe, however with the axiom it would be safe to assume that at least 1 in the possible billions of universes would lead to a reality we get to enjoy today. To summarize why it might seem that Krauss presented the multiverse as a "fact" is because it is an axiom, just like some people 100 years ago assumed light traveled at 186kM/s when there was no way to prove that at the time.
There’s a heck of a lot we don’t understand. Likely far more than we think we understand.
Nothing sure is something.
***** It is nice to see that someone has a clue about the real logic flaws in this lecture. Krauss no doubt is making lots of money off of this fallacy of equivocation. How is this possible? Only by the audience's ignorance or more probably simply their emotional desire to believe that there isn't God, so they relax their standards of logical standards to believe what they want to believe. Your critique is right on. Be Blessed
***** What has this got to do with something coming out of nothing? If something can come out of nothing, then we don't need amino acids from space to create life - in fact all we need is nothing! Because creation doesn't need anything! So science is dead if you believe that something comes from nothing because it just happens. So Abiogenesis didn't happen, nothing happened! And nothing is all we need. It is obvious you don't even grasp the argument of this video. But, then again nothing produces thought so I guess you prove this point.
Is that the best you got? Not much to you is there? How about an intelligent statement from your mouth?
Once again that has nothing (pun intended) to do with this video. This video says that something comes from nothing. So you aren't even commenting on the discussion in this video. But, I guess we can go off on a wild goose chase that is totally off the subject -You are implying that because amino acids are a fundamental chemical constituent for organic life that the fact that it is found in space "proves" that life came from non-life. Not really sure how that is relevant to this video. In fact it isn't. Now if something can come from nothing, then your logical need for amino acids is misplaced. We don't need a logical scientific connection of any kind, because life came from nothing - not amino acids or anything else. So in fact you disagree with this video since you believe that there should be a logical scientific link between non-life and life, but this video says there doesn't have to be a logical link between anything because nothing creates because it is nothing. This is what this video is about.
Right. Although I do make one nitpicky distinction: Complexity should be taken with a grain of salt. I don't think one can say that there is absolute complexity because certain things are more complex to some people than they are to others. To the layman physics is complex, but to me as someone who has a physics degree it's very straightforward and simple. I contend that those who argue for first-cause creationism via complexity are invoking an argument from ignorance.
"the laws of relativistic quantum field theories entail that vacuum states are unstable" is the premise. That is the nothing. It is a testable hypothesis. Albert's book review mostly "quote mines" Krauss' own caveats to his own theories. Brilliant! Sure, other physicists have competing theories. As it turns out, that how science works. The data is fit to models that then compete for primacy based on empirical fitness. You just do not understand how science is performed.
Nobody has to understand how science is performed, science has to learn to define their terms better. How about a better word for the equivocated "nothing" then? If we all want to be on the same page with what's being discussed, how about we use something other than the word nothing? The way quantum this particular science tends to use it doesn't fit the classical definition or common understanding of the word...so quit putting the word out there like everyone is talking about the same thing. Aristotle said 'Nothing...', for the purpose of classically defining and representative of the common comprehension ... is what rocks dream about". Y'all can have your little lab chats and use whatever words you like to use, but if you are going to convey ideas that matter to the general population you're going to have to make smarter word choices.
@@markboyce8081 So, you think that somewhere there is linguistic governance over misuse of scientific terminology by the public? A kind of 'semantics board'? I am guessing that, from the extreme cluelessness of your response, you really know nothing about quantum mechanics? Well, according to the Dunning-Kruger Effect, you are an expert in this field.
@@garbledstoic you presume too much…if it were necessary to be a quantum physics expert, or any other kind of expert for that matter, to logically detect inconsistency in an argument and enter into a discussion about it, then no one could have a discussion. You see, the main reason this platform, and others like it, have a bad name is that people, such as you have demonstrated here, can’t keep from personal attacks. You know nothing of me or what I know, yet you presume you know why I engaged in the first place, and in the second that I think I know more than I actually know. Isn’t this in and of itself Dunning-Kruger in action? A I’ve done is call into question (first clue I don’t understand something) conclusions drawn from what appear to be preconceived notions that don’t consider all the evidence, and then get personally attacked. What use is that to anyone but you? There is in fact a semantics board, it’s called ‘Dictionary’ and it’s intellectually dishonest to equivocate on ‘nothing’ then hide behind amusing quips and academic credentials. Do you think any of that supersedes logic? It doesn’t. Yet trafficking in the illogical and trying to convince folks their ignorant by telling them “trust me, I’ve got a PhD” expecting everyone to fall in line is a ruse. All PhD means is piled higher and deeper. I won’t learn anything from you that I can’t read in a book or find on-line. And I maintain that if you (the royal you) use the word ‘nothing’ that carries a lot of ‘something’ with it, you ought to be honest about it, not trying to hide under semantic rocks. Why would you (the royal you) do that if you were trying to be scientific? Why dodge the question? Why attack rather than engage? Is that scientific? Far from it.
If you (you) want to engage in honest discussion I’m all for it…if you want to engage in personal attacks I pass.
Out of all these scientists I heard, he seems to be just right..
How can you quantify nothing?
Vincent Eugenio it seems like a real nothing does not exist. Space is not empty.
PhantomBlank so in the beginning there is something that don't have a name so they call it nothing? You can't tell a story of things that don't have a name. Title should be "a universe from something".
***** it is just a theory they didnt create another species out of non living things.. Theologian are more convincing because you can't start something if you have a beginning you are just gonna trace it further and further which science cannot explain. That is why god is omnipotent no beginning no end so the question stops when tracing the origin to god..
***** name a species or animals or life form that is a product of abiogenesis where can we see it?
***** we have different god.. Your god is weak and you said our species surpassed god because we can do what your god cannot do.. You tell me who is your god?
Q. Why is there something instead of nothing?
A. Why not?
That which is nothing in particular (actual), is by definition everything in general (potential).
What appears as expansion/gravity is in Reality dielectric acceleration toward the mutual null point of inertia.
3 Principles of Nature:
1. Centrifugal divergence
2. Centripetal convergence
3. Pressure mediation
The nature of the Absolute is all-inclusive, to 'serve' as the Infinite, Eternal Continuum of Being that functions as a diversified unity of potential (Creative Intelligence), actualizing as a unified diversity or Uni-verse, and thus, is the one Absolute Being in which all relative beings live, move and have their Being, the Whole that is ever greater than the sum of it's constituents, the center of which is everywhere and the circumference of which is nowhere, the All in One in All. We are all It, to an unknowable/inexhaustible extent, as the facets of a Diamond are 'both' distinct from each other 'and' the Diamond itself.
Each thing in the Universe is an epicenter of the Universe. We are, to that extent at least, significant.
Love is the recognition of our shared Being.
Namaste'.
That's the most philosophically nonsensical BS I've ever read...there is no such thing as a something that is 'nothing in particular'. If there is 'something', it is by definition 'something in particular', otherwise it would be nothing (meaning it doesn't exist). The only thing nothing is, is nothing. Even a "mutual null point of inertia" is not nothing. That is, it's observable and has been given a label to describe its characteristics. Wouldn't be able to label it otherwise. You can't observe nothing. And you can only label nothing as nothing, nothing more. The premise "the nature of (A)bsolute is all-inclusive" is a philosophical error. You capitalize absolute like it's a proper name, a personality. But it's just another example of someone commandeering a word and changing its meaning to suit a philosophy. Just like Dr. Krauss does by equivocating the word 'nothing'. Other secular materialists have called him out on that point.

Save yourself time, Krauss's nothing isn't an actual "nothing". Fail.
It seems like a fail because our idea of "nothing" is outdated.
AmbiFMA Not at all, Krauss's idea is just an equivocation. Krauss is scared of philosophers because he knows he get's pwned by them thats why he talks shit about them. The idea of nothing is eternal and is unchangeable truth. Your idea of nothing is simply false trying to equivocate.
Thachosen1nee If we're defining "nothing" as: the complete absence of anything, you're grossly in error if you think you know anything about "nothing". Outside the mathematical "zero", nothing, like infinity has no meaning whatsoever in reality. As far as we know, here are no examples of "nothing" in the physical universe, and we cannot even imagine "nothing". So, saying "nothing is eternal and is unchangeable truth" may be fine in poetry, but is nonsense in any discussion of science or philosophy.
Stew Taylor That was a very philosophically naive statement, nothing in our universe is nothing and it very well may be relevant to scientific discussion.
Thachosen1nee Writing "nothing is nothing" may sound deeply philosophical to you, but it's inane. And you call me naïve!
A little known theoretical physicist named Dr Tangerlini predicted that the universe was flat way back in 1979 by a unusual method. He graphed the amount of matter in he universe found by man as a function of time. The amount was getting bigger and bigger. He could then predict approximately when mankind would say that the universe was flat by seeing when his curve predicted humans would have found the required amount.
"You are far more insignificant as you think" Only if significance means energy which is to be doubted. I'd say it in another way: Most of the universe is insignificant to our lives.
It is mentioned that in 2 trillion years time a technically advanced civilization may see their local galaxy and gravitationally bound galaxies, but no other things in the sky. It is true mostly. You will see the CMBR with a perfect Planck curve at those times. The temperature of CMBR will be much lower. The CMBR is constantly reaching us from ever growing distance.
Omg that was Genius i agree there is a factor faster than light but you already knew that good to know I'm not alone
In Infinity things like our Universe will pop in and out of existence and so will everything else. No limits and endless variations of objects ,dimensions, planes ,events, beings etc .. Over and over again as it always has and always will in an uncreated infinite loop .
Totally agree 👍🏻
David Albert is a professor of philosophy at Columbia and the author of “Quantum Mechanics and Experience.” He reviewed Krauss's book in The New York Times saying, " all there is to say about this, as far as I can see, is that Krauss is dead wrong and his religious and philosophical critics are absolutely right."
Albert is NOT saying, Krauss is wrong about theism, Albert shares Krauss's view on that point. Instead Albert laments the use of subterfuge and name calling in place of arguments against the recalcitrant facts of theism.

Yes, you are right about being hired. Money can buy opinions even from professors of prestigious universities. Fox "News" is a prime example of this fact, which can sway the average mindless voter and buy an election.
And as a result we are headed back to the Dark Ages where Gods, Devils, and Demons rule with impunity. It's what Neil deGrasse Tyson has warned about. Religion is just one more way for the King and Ruling Class to rule over the serfs and peasants. And now, King Donald the Crazy, with his cohorts in crime the Republican Party, is in complete control.
so philosophy professors only have valid opinions if they are liberals? Hmm... and CNN and MSNBC are of coarse also unbiased.
You are every bit as good a philosopher it seems as Larry Krauss. He also doesn't realize why ad hominems are not rational.
A philosophy 101 class at any jr. college should remedy both your and Larry's challenge. Best of luck.
Yes, I agree, ad hominems are not rational or make any positive contributions for any given argument (pro or con). However, they are quite common in politics. But politics is not science, so anything goes, let the mud fly. It's the American Way....., unfortunately.
And unfortunately all too common in these discussion blogs, complete with 4 letter words.
David Albert has a Ph.D in physics and is world renowned philosopher of science, amazing how any criticism now is being dismissed as corruption, if we're heading toward the dark ages it will be because of Krauss fan boys who shut down dissent and debate.

I watched this because Hitchens recommended it. And now my brain hurts.
gravity distortions caused by dark matter/energy it could possibly be just ‘crumpled space-time’ from the big bang. Imagine if the big bang was like a giant piece of cloth packed into the smallest ball you can make, then let it go. The cloth would expand, but there would still be ‘creases’ here and there. Stuff could easily fall and get stuck in these creases. And we might think, these little stuff aren’t supposed to make these kinds of creases (its not heavy enough), or maybe something else is making the crease we don’t know of (dark matter), but it just might possibly be only ‘crumpled’ space-time, yet to ‘straighten-out’ as the universe expands.

The nothing he adresses is not an absolute nothing because it contains the POSSIBILITY of something coming out of it. The conclusion is: absolute nothingness is an impossibility, it's just not the way, ontologically speaking, that things are. And what shocks the most is that this "universe from nothing" idea is not new. St. Thomas Aquinas demonstrate it in his Summa Theologica written in the 13th century!
I thought I had a handle on everything he said until about minute 58. I think what he said toward the end is that because we have virtual particles emerging and disappearing in empty space, we could have universes appearing and disappearing as well due to the nature of quantum fluctuations. If one of these universes gets energy added it will expand and exist long enough for life to perhaps emerge, and this could happen more than once, in fact it could happen over and over - some of these could last longer than others, but each would have its own laws of physics as well. And THAT is the reason that not only is it likely that our universe emerged from "nothing," but that the laws of physics we rely on are accidental rather than designed.
Am I getting this about right?

12:50 If you want to skip an over-long preamble and get to Krauss's part.
A question I would have for Dr. Krauss is, consider the fact that eventually galaxies will be moving away from us faster than light. Also, consider that the matter we observe is only 30% of the mass of the entire univers. So how about this hypothesis? The reason we don't observe 70% of the mass of the universe is not because it's dark matter, but because that 70% is moving away from us at a speed which is faster than light.
Only problem with that hypothesis is it would imply that dark matter is not around us which is not the case since our galaxy is bound together by this so called dark matter.
Puneet, but couldn't it be the case that there is currently, matter moving away from us faster than light which is messing up our calculations?
Not quite right my friend. All the visible ordinary matter in the Universe amounts to 2% of the total unknown quantity of the Cosmos, not 30%.
We can still see to within a few hundred thousand years after the Big Bang Using the CMBR.
It is not that 70% of Galaxies are moving outside our field of view- yet.
Rather 98% of the fabric of the so called space 'between' ordinary matter is simply unknown whether it's moving through you, your Atoms or a Star, more to the point this unknown space represents most of the mass and is also what is opposing Gravity & stretching the Galaxies apart! Rather than the Galaxies moving through that unknown dark space.!.
We're far more insignificant than you can imagine. Matter is effectively nothing but pollution in the effectual chance process of Cosmic expansion.
This makes all the predicted life in the Universe almost non existent to the 2% mass of ordinary stars.!
In saying this, as far as we know although life has such colossal insignificance in representative quantity. It seems to hold a higher, possibly anthropocentric value through a chance Evolved capability for self reflection through cognitive complexity & consciousness.
I rest my case.:-).. But the story goes on without us...
Brian Dean Galaxies cannot travel faster than the speed of light, space can but nothing inside of it can. Also we cannot directly observer dark matter but we can observe its effects on its surroundings, so if was can observe its effects then light can reach us faster than matter moving away. To simplify this just think of another body of mass that we can see, planet or whatever, and apply this hypothesis to that. What would happen is we would never see that body since light could never catch the body, thus light would never be reflected back to us and we would never even know that body existed. However I must commend you for thinking, I am always glad to see individuals who are not afraid to express their ideas. Kudos
Charles, I remember Dr. Krauss saying in one of his lectures that because objects in the universe are moving away from us at a faster rate, that eventually the galaxies will be moving away at faster than light speeds.
I can try to find the relevant video if you want.
Krauss starts at 12:47

Sorry Matin Rees for the dogmatic flavor of that statement but it won't cause researchers to waste time because they are already working on this.
What is the weight of the univetse? We measured it? How can you measure something we've only seen 10% of? Sincerely, "Confused" from East Lansing Michigan.
The galaxies that are farther away look like they are traveling faster because the light from those galaxies takes longer to reach the observer. So, by definition, they have been traveling longer in time than the closer galaxies and therefor have traveled farther in the same observable amount of time. This doesn't mean that the rate of expansion of the Universe is accelerating.
Forgive me if I am wrong, but I have never seen anything that explains this when talking about the accelerating expansion of the Universe. Post a link... (smile)

@@charlesdrury9712 I can get light to arrive instantaneously from the stars. What slows down light *from our perspective* is the gravity in the vicinity that slows down the *rate* of time. (It’s not that light slows down, it’s the rate of time that slows down for events to take place.)
So what happens where there is no gravity is that the rate of time speeds up relative to our rate of time so that starlight travels the same (or greater) distance at a faster rate of time. It’s still traveling the *same relativistic frame speed* but an entire second passes by from our perspective at a much faster rate, in a fraction of a second *where there is no gravity* to slow down time. So for most of the time, starlight is traveling through space at a faster rate of time relative to our rate of time perspective.
That means starlight arrives much more instantaneously because the rate of time is free from the effects of gravity for most of the way. With no mass of its own, starlight arrives instantaneously as it experiences no time of its own traveling at the speed of light. We see things in slow motion *where time is slowed down* by gravity.
This relativistic effect allows for a young earth since it doesn’t take millions of lightyears for starlight to arrive through the *void* of space where there is no matter to slow down *time.*
