Dr. Greene, it's so refreshing to hear you speak openly and authentically about the limitations, inconsistencies, and current problems with the standard model of cosmology. It does not mean you're against the same standard model. It means you're upholding to true Spirit of scientific inquiry and culture which must never be afraid to ask the hard uncomfortable questions and admit where and when we do not know the answers. I happen to think that this lack of openness is precisely what has alienated the popular culture from modern scientific theory.

Facts The things he's talking about don't need to be comprehended most of the time. And when they do it's only because he's so far from the truth. This is why science is become like a religion. Following fools liek this guy who thinks he's smart. Without consciousness your intelligence can go in the toilet as far as im concerned.

Im just average joe from Finland 🇫🇮. 53 years, I am in methadone treatment cause I m addict. I shouldn't understand anything about fysics, cause I have heavy machinery education behind me from years 1986-1988. I am ok mechanic, but I have constant thirst for knowledge. And as Finnish, English is my third language, so one more curveball to me learning from your lectures. But I do learn, amazing. Thank you Brian for bringing science to ordinary people and explaining things ,,,,hhm,, the way they are easiest to understand even someone who is not fysisist. About your math formulas I dont understand anything, but in many levels I learn a lot. Thanks also for WSF, that way anybody can learn lot if only one wants to. For my part, I live in Finland and we have great education system, and over all we are at age 15 same level than US students at age 17-18, Thanks mr Green for everything you have done to science.

Should chemistry be denied in the ready conversion of H1 to H2 merely because H2 is difficult to detect in any direct manner in space? A paper by Canadian astronomer Paul Marmet essentially collapsed the "Big Bang" back in 1990 as he theorized the existence of intergalactic and interstellar matter as the cause of redshift rather than a doppler effect -- and accounting for anomalies much more effectively, before the discovery of the abundance of H2 throughout space, though primarily ignored by the necessities of money and career support. An abundance of H2 throughout space in a gradient that will extend to meet that of our galactic neighbor, will also account for the gravitational anomaly where the outer arms of our galaxy rotate at nearly the same rate as the central region. Quantum physics is great, dare I say so before I have dived into the math. However math hasn't actually proven the existence of dark matter, no matter how sophisticated the math is or can be. Circular reasoning isn't somehow justified if you add decades of career building and funding requirements and the consensus building that takes place over time that takes on more precedence than any math in support . . A much greater quantity of H2 in the presence of H1 is the natural result if we acknowledge basic chemistry, exceeding the mass of the visible component of the universe and which must be ignored to maintain control over the narrative and our inability to think and take a risk without group oriented behavior and identification in support.

The bible says nothing about movement because the Earth doesn't move, revolve or rotate. It's perfectly still. We inhabit a motionless realm covered by an impenetrable dome. We use gas pressure to debunk space that directly represents the heliocentric model. Space is a direct violation of the 2nd law of thermodynamics. Using science to disprove the heliocentric model is the best way to get people to learn the truth.

REGARDING your camera focus issue: a simple tip would be to do this before you begin:> You set the focus of the camera to a point behind you by a foot or so or in this case in your video here, to the winow frame behind you, this ought to bring everything in front of that focus point into focus that will/should look clear at all times. if you have focused the camera at a focus point that is in front of you, or even your chair, you may find you will move in or out of focus. this is a basic rule with video cameras, especially in interview settings. therefore allowing for full gesturing & Fidgiting to stay in focus. This minimal preperation is something you should check everytime you sit to record and transmit live or record streams. Now chances are you already found this "Tip" out since this broadcast? As i stumbled upon this live stream two years after you posted it on you tube, which by the way was excellent. if not i wonder if you will find this info i offer. do you have notifications active on your old broadcasts? eitherway i will probably never know. n'er mind. hope you figure it out, or you've been told already.

Mr. Greene. There are so many items (videos) with you in them and bringing us some of the best discussions and thoughts. Thank you. I wonder if the acceleration of the universe has stopped and we're just catching up with it. I wonder if it stopped at the speed of light. I know that suggests a boundary. But the fastest particle we have is a photon. The (accelerating/accelerated) universe must play some role in that speed. As it does now to suggest a better description of 'gravity, in that the expansion of the universe is playing a part _in_ the (new) theory of gravity. If there is no other particle faster than the photon would that not suggest a limit to the acceleration and if that then at some point a _halt_.

Hey, Professor Green! I have written a book about Vacuum or how to prove that there is no such thing as Matter-free area anywhere in existence and it is impossible to start with. Vacuum turns out to be the most important question in Cosmology, as it affects our understanding of Light and Magnetism and Gravity... And yes, this topic was rejected by your journal Annals of Physics. No worries, I gave reference about it in my book. The title of the book is - The True Essence of Vacuum. In this book I also prove that Time Dilation is pseudo science and General Relativity itself has been ignored when considering it... Then I published another book. It is about all problems with Redshift and Doppler's Shift. And this too was rejected by your journal. I prove in this book that Doppler's Shift has never been reliably tested, if we speak about truly reliable tests. And it might be that Redshift is caused by a distance from the object and not from its velocity of moving away from the observer. That will kill expansion of the Universe, Big Bang theory, Dark Energy ideas etc... Title of this book is - Redshift, Nature of Light, Dark Energy. And yesterday I finished the book titled - Hollow Earth Theory Told as Never Before. In it i explain how hollow earth is possible according to existing laws of physics and experiments prove that it is possible in theory. Also, I look at what are legends about the hollow earth and what interesting facts these stories tell...

Something (among many things) I've never understood: If someone is sitting in a chair, is that person still 'moving' at the speed the Earth is rotating on its axis? Or, at the speed the Earth is moving around the sun? And/or, at the speed at which the Earth is being carried along by the expansion of the universe? (Are the above speeds added together to get the 'real' speed of the person sitting in the chair?) And, if the person in the chair were to stand up and start walking at 1 mile/hour, would that person then be moving at the speed of (the Earth's rotation on axis/or around the sun/or the expansion of the universe, etc.) plus 1 mile an hour? Also, I wonder, whatever the 'correct' speed is, is that the speed at which we (or at least the person sitting in the chair, etc.) experience time on Earth? Thank you.

If things are given mass by interaction with the Higgs field, and then space expands (reducing the concentration of the Higgs field), would that explain the counter balance to gravity and account for the acceleration? Would also seem to explain the tiny tiny 10^-25th size values. Of course that would mean newer things should have minutely less mass its older counterpart would.

So if I am understanding Brian Green'e explanation of knowing how to travel to the future by traveling away from earth and then back again allows us to travel to the future, then would that mean that without some type of instantaneous travel, that it would then be impossible for a multi-galaxy civilization to exist in theory due to the constant flow of time due to the time it would take to travel back and forth (again without an instantaneous form of travel) because years could literally fly by depending on the location of say two planets attempting to send supplies to each other in a realistic frame of time to meet the needs of the populations of the two places? In other words, one planet could put an order in for supplies, and by the time the transport ship went back to the original planet, gathered supplies, and flew back, in theory those people could have died off years ago by the time your transport got back? Did I explain my thought correctly?

St.louis, Mo. area. Does anti matter and its large family of particles point to a polar cosmos. Whereby the ambient potential charge difference is part of the charge distribution symmetry that is the foam, pressure, resistance, field effect etc. and or the opposition that is pushed against by mass to create a curved space time fabric? Thankyou for your show. It is truly inspiring. Please excuse my question if it is unreasonable.

In order for light to maintain the universal speed limit if time slows down space has to expand. In the regions of space that are expanding time has slowed down and light is traveling at a constant velocity. At the event horizon of a black hole space has been stretched so far that light and time would appears to have stopped. Gravity waves show that space can be stretched or compressed. Just wondering if these are valid perspectives.

We tested this with repeatable results. One of the best postulates is that the further the differential, the faster the race to equilibrium. There is a goldlocks temperature where water freezes faster is it begins above ambient. To get things to move quanta or change states, it takes a fair amount of energy (or differential) if already in turbulent, high differential and dynamical, it is already in a state of transition. Fun experiment! Another couple fun ones we played with as high arctic weather scientists was supercooling (this can actually be done down to -60s where water nucleates on its own molecular lettuce!), making stratus clouds from just a kettle of boiling water rapidly exposed to

when water changes from liquid to solid 'phase change' it gives off energy and temporarily goes up in temperature above 32f. so when freezing water that already has heat energy already in it; it sorta skips the phase of rising above 32f and giving off that energy. so that's one theory why heated water freezes quicker..

Should chemistry be denied in the ready conversion of H1 to H2 merely because H2 is difficult to detect in any direct manner in space? A paper by Canadian astronomer Paul Marmet essentially collapsed the "Big Bang" back in 1990 as he theorized the existence of intergalactic and interstellar matter as the cause of redshift rather than a doppler effect -- and accounting for anomalies much more effectively, before the discovery of the abundance of H2 throughout space, though primarily ignored by the necessities of money and career support. An abundance of H2 throughout space in a gradient that will extend to meet that of our galactic neighbor, will also account for the gravitational anomaly where the outer arms of our galaxy rotate at nearly the same rate as the central region. Quantum physics is great, dare I say so before I have dived into the math. However math hasn't actually proven the existence of dark matter, no matter how sophisticated the math is or can be. Circular reasoning isn't somehow justified if you add decades of career building and funding requirements and the consensus building that takes place over time that takes on more precedence than any math in support . . A much greater quantity of H2 in the presence of H1 is the natural result if we acknowledge basic chemistry, exceeding the mass of the visible component of the universe and which must be ignored to maintain control over the narrative and our inability to think and take a risk without group oriented behavior and identification in support .

I agree that the next revolution of modern physics is in the fundamental understanding of spacetime. Is spacetime an emergent property of something more fundamental that has not yet been observed or theorized? Will we find there how the quantum fields finally interact with gravitation effect of spacetime (such as inside black hole event horizons) and/or how to bring all four fundamental interactions (strong, weak, EM and gravity) into one unified theory?
