With all of their sturm und drang, It's no oversight that whether Penrose, Greene, Hawking....ad nauseum,
NONE OF THEM will come right out and say: "We've corrupted the laws of thermodynamics".
THEY KNOW THEY'D BE HOWLED OUT OF PHYSICS!!
#1--HEAT cannot originate de novo
#2--HEAT IS NEVER ETERNAL...this universe cannot be eternal
FN OOOPS!!
@@WayneLynch69 so you're saying you're not a big fan of Guth I take it.
What a treat ! My favourite guy.
If you have watched a few inch column of clear water at the bottom of a pot just at the beginning of boiling on top of the stove, then you have witnessed what resembles the creation of multiverse in the form of bubbles that expand, burst, and give birth (space) to bigger and hotter multiverse (bubbles) to develop. The process that seems to have never started and never ends as long as the heat intensity does not destroy their formation.
So, whose pot are you living at the bottom of?
I love Oldies. 🎵🏆
If there is a multiverse, then it seems possible that we simply live in one of the universes in which there is more matter than anti-matter. Perhaps in other universes, the balance is different. In other words, the preponderance of matter over anti-matter cannot be derived from first principles but instead results from some mysterious initial condition which varies in some way from one universe to the next.
I'm surprised with the low view figures.
It's Alan Guth. Genius
as always, doc alan guth gets right to it in a clear and succinct way. a lesson here is that hey you outliers are important. 😅
so to me as a rank amateur would you say that at or just before the begining were there any elements present like hydrogen or helium or just atoms or the parts of atoms? thnx steve
They don't have a theory for the very beginning, the moment of creation, or how the universe was created. The Big Bang theory explains how the universe expanded after it was created, not how it was created. They say they can't develop a theory for the creation of the universe because two of their important theories are incompatible, general relativity and quantum mechanics. They're working on reconciling those two. In the early universe, according to what Alan said in this video, there were quarks before there were elements or atoms. Then, as the universe cooled, quarks combined to form the nucleii of atoms, so then there were elements and atoms. (Quarks are elementary particles that are what protons and neutrons are made of in the nucleus of an atom)
steve perry I believe space time and energy existed before matter. So in the very earliest stages there was no matter, mass. Within our dimensions of space and time there was no “before”.
just wait in 30 years we will be traveling to other universes with warp speed and looking back like wow, we sure were stupid.
Someone hit the RUN button.
Having investigated this question very carefully, I have come to a conclusion.
Universe begin after an Universe-potential.
Amazing. We are here because of uncertainty.
An uncertainty in the fundamental mechanics of the quantum realm. If there had not been this uncertainty, the universe would have expanded in such perfect homogeneity that not a single fluctuation would have caused the gravitational imbalances needed for particles to attract one another, and subsequently "cascade" into the large scale structures of our universe (galactic filaments).
Could one have asked for a more succinct rebuttal to the concept of an intentional being behind our creation? We are here because of the Heisenberg uncertainty principle, and the Evolution by natural selection which followed it. Without, this universe, as I understand it, would be a sea of quarks, with no more or less meaning than our universe save the forces which precede it's very formation.
Ill defined as theism already is, could one argue that an intentional, personal, loving "God" created us through uncertainty? Sure, with a small side of hubris.
You're very astute and obviously well-versed in quantum physics. I'm an older man and I've read Guth since he appeared on scene with "inflation" I guess at least 25 years ago. I understand you and I agree with your educated observations (sea of quarks). I was disappointed to hear him say at the very end that the theory indicated an "ultimate beginning." And if the theory requires "a beginning" then it's explained by the quantum fluctuations on a Planck scale by positive electromagnetic energy and negative gravitation energy fluctuating for as long as it takes to finally at some point "smooth out" (Stephen Weinberg) and for a moment create an area of zero energy, and well-known dynamics (mentioned here by Guth) allow for the exponential growth (70 times faster than light (Guth) and the rest is particle physics. Peace. Oh, yeah, Nobel prize winner Stephen Weinberg predicted three quarks and named them and told us their spin, etc; we humans built the Atlas at CERN and found all three. Weinberg said words to the effect that if science can do anything to weaken to hold religion has exerted on us, it might be its greatest contribution to mankind. So yeah, everything we tell the creationists is used by them to lie to their flock. God was the Higgs boson; now he's fargin dark energy. Hard to get a handle on that dude.
@@ClassicRock1973 : Actually they don't generally. And why are theists on youtube so nasty, it sure isn't a sign of confidence to substitute reason with hate speech, just an admission that you don't actually have any sensible arguments in support of your position. But, we knew that already.
@@ClassicRock1973 Hey, dumb ass, looks like you tried to write "you won't be" blah blah but of course, your ignorance of third grade grammar and spelling precluded you from making a relevant point. Piss off. I suggest that you and Roq might get a room and actually study. You made his point moot by starting out ""so nasty." When you decide to offer even a shred of evidence for that spooky crap, I'll get a Nobel prize and a million dollars for your mom since you're not an adult yet. And oh yeah, fuck off. Why butt in to an adult conversation with bull shit? Oh, yeah, nothing else to offer. But thanks for the laugh.
@@roqsteady5290 "Hate speech" is Free Speech
The uncertainty that you speak of seems very highly finely tuned.
The cosmic microwave background radiation displays fluctuations of 1 part in 100,000, enough as you say to cause organised structure to emerge but not too much to cause a universe dominated by black holes.
Add to that the critical density of the universe (the balance between matter,energy and the expansion rate of the universe)that physicists know is balancing on a ‘knife edge’ and we have an extremely finely tuned universe.
And of course the further we go back towards the beginning the more finely tuned those initial conditions would have needed to be.
It smacks of having been Created as many eminent scientists who’ve looked carefully at such have acknowledged.
Audio level is way too low
I connected my pc to my guitar amplifier. No kiddin', my ears are bleeding.
Get a better sound guy please.
this guy got his PhD at 25
So? Many people have accomplished as much or more by even earlier ages. Guth's concept maybe turn out to be just a bit more convenience than actual fact. Just saying.
Damn, that's harsh. He wasn't even implying that.
Did gravity come about as universe cool from inflation? What led to conditions in which gravity could start?
I think gravity was always possible in space, space just needed particles to warp it.
see, he said it, the earth is FLAT boiz
Crypto Rough Cuts the universe actually seems to have a slight curvature, according to the newest research.
We are nothing...nothing is all there ever was, nothing is all there ever is, nothing is all there ever will be.
Another question would be when will some kind of brain chip come out so we can understand the mathematics of this stuff.
There are others ways to go about understanding it. For instance, study.
CCC
he exactly looks like the Kind of scientist i would believe Blindly ................
The first stage in understanding any subject is to work out what to trust and why. Unfortunately, it is a step that many people never can never get over.
Creation began by something in the Night
First of "all" ; The universe has no absolute beginning as absolutely nothing comes out from nothing. One key components for this widely misunderstood conception of beginning is a realization that we can not extract any information beyond Big Bang and that validates our conception of absolute beginning. Not a logical conclusion, but a pleasant one, that feeds our hubris etc. "makes me feel a little bit special..". Just quarks without understanding what is the thrue/fundamental nature of matter. For ex. the absurdities concerning elementary particles such as: How can a particle which doesn't consist of anything but itself send & receive any information i.e. have any kind of formation, what is the density of a particle that consist only of itself, what is the shape of this assumed particle, as it must be 3D? "There must be a ultimate beginning" even there can not be.
How do know something can't come from nothing? We've never encountered "nothing"
The question is still not answered
There's a prior question to that of how did our universe begin?, namely, did our universe begin?
The universe is in fact here. At some point in the far distant future it will run out of energy. We have not arrived at that point so an infinite past is not possible. Had to have had a beginning point.
HOW MANY TIMES DO I HAVE TO SAY :: NOTHING IS REAL. BOTH REALITY. & A THINGABLE NOTHING.
Nothing is true.
Everything is permitted
@@Caligula138 I have no Idea of what i was saying .. But thanks.
@@exxcellbx6139 hahaha! 😄
The Universe didn’t begin and there is absolutely no reason why it should have. As a corollary it won’t end either due to its entropy being constant.
They keep asking questions that no one has the answer to. LoL
The universe came into existence when the first observer of it came into existence. We are living in a simulation that was spoken into existence by a Master Programmer.
+Brad Holkesvig
How do you know that? Sounds like you're making up as you go along. God is a figmenet of your imagination. Go ahead and prove I'm wrong.
+Shahid Ashrif
I don't have to prove to you that you don't know our Creator. I already know you don't know Him.
In quantum physics, an observer is merely any other particle, it does not mean a conscious life form.
As for your “explanation,” resorting to Bronze Age mythology doesn’t explain anything, for who or what created God? Religion is a primitive culture’s explanation for why the sun goes down out night, why droughts happen, where the earth comes from, and that sort of thing. Scientific inquiry has produced actual answers to these questions, so there’s no longer any need to resort to primitive superstitions like gods and demons.
@Tyler Brown - you said, "resorting to Bronze Age mythology.."
How do you know Christian belief is derived from Bronze Age mythology?
Ken Elyon It’s not. Christianity appeared far after the Bronze Age. Some beliefs do date back to it, but that’s about it.
we need more than uncertainty principles, probability, super position and multiverses .
these terms have become metaphors of the scientific community.
uncertainty principle = you really dont know
probability = you want to believe
super position = you want to have it both ways
multiverse = in another universe you dont have to be wrong
We will never know because no one was there. All we have are educated guesses. For all we know a glow in the dark unicorn with 6 heads created the universe...we can't prove anything.
He talks a bit to quick great tho
He doesn’t really know
From what institution did you receive your physics degree? If you don't mind my asking...
10splitter credentials don’t really mean that much, tbh. It just means you are willing to jump through hoops enough to satisfy others’ expectations.
But unlike religions he doesn't claim that he does. What he does do is give us the picture of where we have actually gotten to so far, according to the best theories based on the observations we now have access to. That is as good as it gets and much more sensible than dogmatically believing what it says in old books written by people who hadn't even worked out that the earth was not flat.
I majored in physics for one reason and one reason only, I didn't care about a career or anything like that. I wanted to know "why is there something rather than nothing?" I was at the University of Minnesota the day Alan gave his talk on Inflation, in January 1980; I went to the talk. As someone who has been looking into this for an entire lifetime, in my humble opinion Alan's Theory of Inflation comes closest to answering the question.
In the beginning God created the heavens and the earth.
But who created God?
Our Creator hid His creation so well that His characters will never see it.
+Brad Holkesvig
Very convenient!
Everything that we experience came from information that doesn't require any hard physical matter to be stored on. Our Creator's computing language and technology is much more advanced than the simple technology He had His people build.
That is pure conjecture on your part that neatly evades the issue of proof and evidence. Basically you're arguing for the right to claim whatever properties you wish, for your deity. I'll only begin to take you seriously when you actual tell me how you know what you claim you know about God. BTW the bible does not constitute evidence of anything!
Shahid Ashrif
You're right. The Bible is not evidence that there is a Creator of us and everything we experience with our created senses. It was our Creator who had me write and speak for Him this past 7 1/2 years where the knowledge came from to know how we're created. He taught me everything He wanted me to know before the body that's typing this post has been killed by Christians who hate the Truth.
I have known our Creator for over 36 years now since Dec. 7th, 1979 when He spoke these words into my mind, "I AM YOUR CREATOR". From that point on, He began a long 28 1/2 years of getting me ready to write and speak for Him. This takes a lot of trust in order to write and speak about things that are about the past and the future besides how we were created.
In order to get me to trust Him before He had me start testifying to His knowledge, He had me go through all kinds of crazy experiences that most people would never believe. Once I learned that He's in total control over my body, it became easy to trust Him for each word He put in my mind to write and speak about hidden knowledge that has never been revealed to anyone in this universe.
I learned about quantum mechanics in visions that He had me experience. This means I didn't need the mathematical language to understand that particles are only illusions that can never be contained and observed by us. They all came from the language of our Creator which is totally invisible to us. His computing language is nothing but vibrations that don't require any matter to exist. In fact, matter can only be observed when these vibrations are processed into an observable object such as a particle.
It's very difficult for me to believe that quantum physicists can actually believe we're real people with what they understand. Some of them have come out and actually tell people that we're living in a computer generated program but most people don't believe them.
However, our Creator has used the computer technology and many of the programs to teach me how He created His program called Eternal Life with His voice. The last bit of teaching He did was to have me look up in Google for any computer programmers using voice recognition programs to speak code into it from their invisible thoughts and build computer programs.
Once I understood that there are over 100 computer programmers speaking computer programs into existence, then I realized that this is how our Creator created His program where we are only characters in that program.
I can show you many OT prophecies to show you that they fit the knowledge that was revealed to me through the written and spoken testimonies besides all the visions and dreams I experienced this past 7 1/2 years, soon to be 8 years on June 16th, 2008.
What we observe in this world is only an illusion. We are not real people made of hard physical matter and all our experiences are nothing but a running program that was created a long time ago.
People showing your symptoms are usually medicalised and treated. Enough said!
Alan Guth is a brilliant man, but he peppers his talks with 'maybe', 'one imagines', 'we believe', 'we think' and the like. The theory he comes up with known as 'inflation', tells us that, for a very short time, things could travel much faster that the speed of light, which Einstein tells us can't be done. Science - it is all based on guesswork.
Nothing travelled faster that Speed of Light. Space itself expanded.
God started with a photon.
These scientist talking like what he says is gospel.
Pope’s, priests, preachers and holy men are making so much more sense talking about celestial wizards shaking universes out of their sleeves
When someone really clever is talking rubbish we believe him
Lindsay Forbes If by "rubbish," you mean "observations that provide empirical evidence, that have been peer reviewed and produce predictable results, as well as fit all current mathematical models."
michaelgorby where is the empirical evidence for the matter / antimatter theory?
michaelgorby and which of the inflation models which were peer reviewed and now discarded do you suggest.
As for homogeneous, GR equations can o my be solved if you assume that the universe is homogeneous. The evidence if you look for it suggests otherwise.
@@lindsayforbes7370 it's all in the math. Just because you don't understand, you don't get to denigrate physics, while using a computer..... MADE POSSIBLE BY PHYSICISTS
@@lindsayforbes7370: Evidence isn't evidence "for" things. Rather theories are explanations of empirical observations that are predictive, falsifiable and make the fewest possible ad hoc assumptions. If you don't like that, so be it - but it works.
Is it just me or does Alan look swole af
i was just thinking that
FROM NOTHING!!
Cut the BS ,this is a thought universe
