The more we know, the more we discover that we don't know.

Time does not exist? Well in that case, they best not accuse me of being late to work again.....if they do I'll have to educate them about how time doesn't exists, there is only now and being late is only an illusion.

Time is an arbitrarily defined concept that is used to measure entropy. It is not a constant. Time is a tool that human beings use to explain the changes in ourselves and our environment.

We live in a eternal universe. And as a humane we don’t have the brain to understand eternity.

Science = man's best guess....

If time does not exist, then, why the hell am I wearing a watch?

The more you know, the more there is to know...

A teaspoon of the ocean is not enough for us to judge what is actually out there.

So once again we know nothing .

James Webb got a lot of science teachers hating their jobs rn 😂

Wow! Who knew Robert E. Lee was not only a general in the Civil War, but was light years ahead of the scientific community writing papers on quantum physics with scientists more than a 100 years younger than him. Seriously though, at the 25:53 mark there is a picture of (supposedly) 3 physicists: Laurent Freidel, "George Herminic" and "Robert Lee". This first caught my eye because the picture of Robert Lee is actually Civil War Confederate general Robert E. Lee. I think you mean Robert Leigh and not "George Herminic" but Djordje Minic. I don't know much, I'm just a housewife and elementary school teacher, but this sort of unnecessary error in information leaves me questioning the integrity of your research capability. It is a shame because I personally love learning about Physics in a format that is easy for laymen to understand.

Once I began thinking about time, I felt that it doesn't exist as a fabric or anything else. It's a concept we invented to count (quantify) the intervals sustained between movements. It's hard to define the concept of time without using the words time and space. I'm probably not making sense.

Reality is much stranger than fiction

Time is nothing more than a man made measurement of matter in motion through space.

How does things age when there is no time? The reason I am 1 day older than yesterday is because 24 hours has gone past. I call that time. Healing a wound takes time or not? If not, what?

The problem is that everything, including space-time is the product of our brain interpretation of the actual reality. (something like the user-interface we have). Who knows what the truth really is. Donald Hoffman explained it well in the interview with Lex Fridman.

I cant wait till the day they make a telescope that makes the James Webb telescope look old.

Time is just how the brain percieves things. What is really happening is we are in a singularity of time. So things change and evolve within that singularity. Time does not move forward or backward. It stands still and we move within the static space.

I'm no expert but it seems to me that there are always assumptions at the base of scientific theories, often hidden. I could be wrong but my understanding is that the big bang theory comes from the assumption that the red shift observed in distant galaxies is due to the Doppler effect for example but it could be that there is another explanation; in fact I remember coming across a suggestion a while back that the red shift could be explained by varying mass although I've not looked at the relevant formulae to check if this is reasonable. One problem is sample size. Imagine picking up a random grain of sand from any beach in the world, would it be reasonable to conclude that every grain of sand on the planet has the same properties? This seems like nothing compared to space, we don't actually know how big it is or even if it makes sense to associate a size to it. For example, it is usually assumed that the speed of light is constant but we haven't made any measurements outside of our solar system as far as I know. If an assumption turns out to be wrong then anything derived from it is on shaky ground. I don't think it helps that the term "law" is used to describe what is actually an observation, it implies rules that must be obeyed but nature is what it is, it doesn't need to obey any laws just to satisfy scientists! I don't know if scientists actually believe they are as rigorous as we are led to believe or maybe that's just the way they come across when they are dumbing down explanations for the masses through the media but I wish they'd put more thought into laying out any assumptions they make. An assumption is not the same as a fact The problem with science is that it seems to be riddled with ego's and careers vested in particular ideas, it seems difficult for new radical ideas to gain any traction because of politics essentially.

We are used to thinking of time as an invariant fixture, but there are more and more signs that it can go backwards, forwards, or not at all, depending on our relativistic multidimensional perspective. Our thinking is trapped and paralyzed in our three dimensional prison cell.

While I enthusiastically nod at Vito Lipari's definition of time, I am aware that we are both humans, with our human limitations, such as only experiencing life in not quite four dimensions. The cosmic realities and truths might be completely impossible for us to comprehend. So such concepts as space-time may be wrong from some cosmic perspectives, there's only so far from these concepts we can go and still find them useful. At least in one lifetime, it seems, for most of us.

Maybe all the galaxies experience time at the same time. Everything is instant, only our perception separates now from before and after?

Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city, with no interaction with each other until they used the subway, complain about the same time paradox unless it was effected by it? Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're randomly given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? Ti-i-i-ime, is on my side. Yes, it is!

As below so above, if you think about how humans interact with each orher, and how it resembles other processes on different scales in different sciences it makes a lot of sense that spacetime is a product of objects interacting.

I'm okay with being wrong. Let's grow up and face the new reality. C'mon science,it'll be fun!

Never cared for hearing "scientists" discuss theories as if they were proven facts. This should humble a few of those "know-it-all" scientists, but likely, it won't.

I knew time didn’t exist when first learning about the states of matter in high school. Time and thoughts are the only things in the world that do not have any matter.

I knew at 17 time didn’t exist. It’s just a unit of measurement us humans use with our puny brains

Please read the Rig Veda and the Upanishads. This mutiverses and universing contracting and expanding is already mentioned. These Vedas are atleast 3500 years old, more likely older than 7000 years old.

Even a broken clock is correct twice a day.

Michio Kaku, where are you, I had a slight glimpse of you?!?

When I first heard of the plans for the JWST, I predicted that, if it were built and deployed successfully, it would find MOTS (More Of The Same), and that the Big Bang was wrong. Glad to see it seems I was correct. Now if only some astrophysics department would offer me a big grant……🤔😂

Doesn't time simply equate to motion? That is, an absence of motion means there is no time? Physics rules, literally!

Lemme get this straight... Mel Brooks... was right about the universe during Spaceballs?! XD That's both hilarious and fascinating

I truly believe that a person will emerge as a free thinker and then a new age of thought will begin for humankind, most theorists now, seems to me, that all has to be quantified as though on a scale but time will come when a person with clear decisive thought shall provide impetus for all science. Enlightenment shall follow.

Time is a human construct

Bing Bang and Big Crunch = Pulsating Universe ... this is described in 5000 year old Vedic literature which contains the answers we seek.

Light gets dimmer and smaller the further away it gets. Even if the galaxies are growing, they could be moving faster than we think. Our perspective could be off. They might not be as big as the hubble or viewing through the atmosphere of earth makes them appear.

It’s just seeing light and like is a reflection of what once was… it’s just a reflection like a mirror

I hope we have enough time to find out more information about how

Space is cool

Is there a maximum distance which quantum entanglement is true? Or is it just a guess that it has no limit?

I'll watch these with interest but won't let it influence my mind. Science is always changing theories change all the time.

We'll always be questioning is my thought because we always have questioned.

The big bang theory never made sense to me. Seemed too simplistic.

The narrator deserves a own Netflix series !

25:50 Robert E Lee that great physicist... lol 😂

Very well scripted! Whoever wrote this should be congratulated; so much information in one half-hour presentation. AND it was articulated at an accessible level of standard English usage. Great job, guys 'n gals!

Robert Lee the physicist looks similar to Robert E. Lee the General. Could he have time traveled? Or perhaps traveled through space and time?

about time! finally a good report from this channel,

The James Webb telescope paid for itself by just disproving the big bang theory.

Wait till they build an even bigger telescope!

I remember even back in my highschool days (70s), my friends and I would try our best to better understand how time really works. We would be stumped every "time"! I heard it explained as a field of energy, that is fluid in nature. It's odd though, there are well documented instances of "Time Shift" experiences where people have found themselves temporarily entering a different time period, then re-entering their present, as if time periods all exist at the same instant?

what was our first satellite/telescope thrusted in space? so long before james webb tele, we already did a "time machine" but not for personal infos but for global/universal disposal

What if space isn't actually real? Maybe it could be a contour of varying degrees with which we can collapse wave functions to affect events. Wave functions that have more plasticity encompass things that APPEAR to be closer to us, while those more resistant are associated with things that APPEAR farther away? And, the information would seem take longer arriving at our measuring devices, because of the resistance to collapsing the wave function.

They got to change the name and theme song to the big bang

Khayaam persian scientist and poet said : as he leaned more he understood that he dose not know much

we are in the concept of infinity. Where we began is where we end and where we end is where we begin. There is no on creator but creator to a creator. Which on came first chicken or the egg? neither!

Remember that every single thing and belief on earth are made up by ourselves for ourselves, nothing else.

Everything you do, every operation changes the future, however nothing you can do will change the past. You can wrote a note to communicate to yourself into the future, however you cannot communicate into the past.

Just when I think I have enough information and understanding about this to actually pounder questions and come up with my own ideas and theories I realize I need more info. Most of the information about subjects like this were very basic. If you've seen one you've seen them all but since the Web information I haven't ever been able to know is everywhere and lots of it. I finally am getting a basic idea about the nature of space , time galaxy and star formation. I 28:22

Nothing is real even our lives, we are here as a aquarium pets of something higher being

Yet educators have been teaching the "BIG BANG" theory as if it were carved in stone and the pure, unadulterated, truth. They've done the same with evolution and the same has happened with that theory, it's fallen apart. So, what absolute truth are you going to insist we believe next?

If were working under the assumption were inside a black hole the largest plane of view would be the size fo the disk around the black hole where the light is sucked into the hole. The rest of the space would be invisible to someone in the hole. Spaghettification would be our reference of perceived expansion. Of space.

18:26 in the past when new technology has expanded our understanding of science, it has also changed our perception, it's no different now.

Does "Now" exist?

Maybe I know where could be another contracted spacial dimension in our spacetime. We need to search it in quantum physics under the Planck lenght. If you could miniaturise yourself enough, to get through the quantum fluctuations, you could appear in front of the relict radiation which we observe in the "end of our observable universe . Its spacetime loop

To reverse time would take a mass that is immensely large or dense. No carbon being could survive that pressure. Think black hole. No, you can't undo your regrets.

Your picture of Laurent Freidel is Carlo Rovelli 🙁

You won’t believe me, but that is the real Bruce Lee.

All of history, all of time is happening simultaneously. We are a pin point of drama.

I lay claim to all galaxy’s. Pay me rent now. That’s how dumb we are.

Space, Time and Matter began at one moment. One cannot be without the other two. Looking at matter is a distraction and gives us a distorted look at Time. We see matter in three dimensions when matter is in dimensions we cannot imagine. The Bible is full of quantum entanglement such as MATTHEW 25:40 and Prayer. My grandmother knew my uncle was hurt in WW2 an ocean away. That's another entanglement of human Love.

Love is the connector , good luck in your journey.

Time is what keeps everything from happening all at once or so i heard

Once you are born you are tethered to that point in time ,that point in space and the more space expands the further you are away from your tether aka aging im looking into tethered time theory 😂

We will discover more and more when it’s appropriate for us to do so aka have that knowledge

Even still, there are people who insist the big bang occurred.

One measure of things over time will be there for other's to learn from early existence just like us for them. That is forever real 🌎🧐

So the big bang never happened and time does not exist, or at the very least exists in our minds for our convenience.

I believe quantum particles are particles that exist in past, present and future at the same time. That's why quantum particles that do not connect in any way, react the same way. It's the same particle. How do these particles come to exist in all of time, at the same time, you ask. Maybe the same way all of matter gets focused to one point. This is how all the TIME this particle wasn't there, exists in the same TIME it is there. See, quantum reality. I believe the TIME Force/quantum reality/quantum realm is fluid. When it takes 500k of our years for one millionth of a second to pass inside a black hole. (Heavy Time) Then you have a white hole's ENTIRE existence flashing by in an instant. (Light Time) You can imagine time being a fluid force. I mean, if it walks like a duck and quacks like a force, it might not be just a causality.

Awaken to reality! The Universe is Electric! Plasma is one of the four fundamental states of matter and 99.99 of the universe is in the plasma state not dark energy or dark matter. Plasma which means that magnetic fields and currents are almost everywhere in the Universe.

Switch off JWST and we can all carry on sleepwalking. It would be a relief.

Thanks

love this Love This LOVE THIS and … wtf? At 25:52 there’s an old photo of Robert E. Lee -- he was the general in charge of all Confederate forces in the American War Between The States (aka “The Civil War”) (who knew?) which ran from April 1861 to April 1865; if he was doing Space-Time thought experiments… then the quantum particles inside my head are working overtime (which is time & a half). Surely my man the physicist Robert Lee’s got a photo/image befitting his current incarnation? But… solid, ‘nuff said… I LOVE it all!!!!!!!!!!!

I sry I don't understand I thought the scientific method was to take a theory and test it... Not this is what we want to be true so let's try and make it work at any cost? It feels like these "scientist" have forgotten what that means and string theory or LQG is the opposite of science.

We don't have any time for this.

I love it when all these so called astrophysicist get stuck in such a huge pucker factor since there was soooo much push back on the big bang from conception....😂

*Please Take this with a grain of salt*

oh really, pretzels and trampolines,, kiku has lost his marbles

We came from a place where eternity is not a duration of time. A deathless place. Now? Stuck to the dirt on a prison planet. We were in a rebellion, a war, a judicial process, a condemnation, . So we brought all these ideas with us. War, judicial process, . There is nothing new under the sun, what is , was before.

I'm still waiting for nasa to show up my door because I said time doesn't exist years ago when all these scientists where saying time and space are interconnected. Clearly I'm smarter than them

Best as I can summarize it, we are not a part of the time dimension, but we are being accelerated through it, and are effected by it.

Time just perception from object, space and force. One this element gone than Time never excist. Time not the 4th Dimension, something else must be replace TIME.

How about this? Dark Energy is EQUAL to Energy plus TIME, for our purposes here, "HEAVY TIME." Mira, look, we see this electron orbit however many times a minute. We set that as our base reading, right? For our plain of existence, anyway. However, in these pockets of, "heavy time," that same electron now has readings of a billion times a minute because time is HEAVY here and passes a billion times faster. Or, energy where there shouldn't be energy / dark energy / Heavy Time. See, in that same minute to us, that electron aged a billion times faster and therefore has given off readings of dark energy. Dark energy IS "HEAVY TIME." It's the difference in TIME that we're seeing! Maybe. The light from these galaxies have been aged by going through pockets of dark energy or "heavy time." Numbers used for reference only. TI-I-I-IME IS ON MY SIDE! YES, IT IS! Now we look at the other side of the coin, dark matter. Pockets of dark matter are actually pockets of "LIGHT TIME." Mira, look, if heavy time is faster pockets of time. It stands to reason, light time would be slower pockets of time, right? Making our base electron seem to stand still. Get a pocket full of seemingly motionless nothing and you get a pocket of starving dark matter. In this case, "starving," or slower pockets in time is the same as creating a vacuum in space. Since this pocket of "Light time" is "starving" and everything outside this pocket of dark matter is in a "heavier time," it makes it appear dark matter is attracting when really it's just a vacuum, IN TIME, trying to equalize. Making it stand to reason, by my, "I'm not smart enough to give anything more than this simplified reasoning, that Dark Matter is "LIGHT TIME" and Dark Energy is "HEAVY TIME." Maybe. Now think about this. As light travels through the universe and passes through these pockets of Heavy Time or Light Time. Doesn't that "age" that particular beam of light? Doesn't that beam of light that is say 40 million light years away now look like it's 100 million light years away? If I'm right, it would explain why these 6 "old" galaxies are being discovered. Also, if I'm right and someone proves it, you must name it after me and give me a cut of the Nobel prize winnings. Pass it on please. and thank you. P.S. I may have gotten the names, LIGHT and HEAVY, backwards. Thanks again and don't worry. Where I come from, crazy is a compliment. ;-P

The big bang is much older than we first thouht

We are all on a rollercoaster ride in spacetime, so just plain time itself would be hard to find alone just like objects just sitting in space. Considering this, time should be considered as a unit of measure of purpose. And where you find purpose, you find spacetime.

Is not time a perspective ? We are but a moment .

So all we do is trying to construct an theoretical model that oure brains can accept 🤔 Is this the goal ?

if not expanding what's red and blue shift
