[@David-di5bo]

I really love the style too, that they maintain a single narrator the entire time. A lot of these shows like to throw in random physicists sitting in their office talking for a couple of minutes here or there -- keeping a consistent narrator for everything, even to read quotes from others, really smooths it out and ensures the message is well constructed and organized from moment to moment.

@@8mileshigh (Thanks for the catch about Einstein; corrected.) If I have to point out the mistake in that sentence, you'll probably just respond that it's not a mistake, or that it's too trivial to take issue with, or that it's a "style" issue (it's not), but it reads: "...questions to which Eistein's theories only begin to answer." At first glance it should be obvious that the writer started out to write one sentence but switched in the middle to end up writing another; it should have said, either "...questions which Eistein's theories only begin to answer..." or "...questions to which Eistein's theories only offer the beginnings of answers..." or some such variation. TR;DR version: there are too many "to's" in that phrase; one ANSWERS a question; one presents an answer to a question; but one does not answer TO a question. There are other spelling and wording issues; I am done with this channel and am not going to revisit it to dredge them up for you. Consider them exercises for the reader. If you can't catch them or just don't care, no amount of explanation my part will be anything but wasted. My overall impression from this and other offerings is that, while this channel boasts shiny production values, its cultured-sounding narration is laid over careless and inaccurate writing, and it does not deserve the gushing praise that other commenters have posted here.

To keep in mind, the vibrational universe is periodical as a function. It's limits are where motion starts, and the speed of light, the fastest it can move before it no longer produces tactile matter that respons to time ,space and gravities. Faster or slower, it is potential or kinetic energy that permeates instantaneously. Leads to what we are calling entanglement and the quantum slice tomography that exposes the Fourier Effect on the whole at this exact moment of now.

Another great video! Another of my questions to all of 7.1 Million I'll never meet--When I was about 3-4 years old, I distinctly remember that when I got into the car with my family, I waved good-bye to our house as I knew that I was still while the rest of the world moved around me. My dear sister told me that everyone has had that belief as a child though mine hasn't gone away . . . (she was the only one who could translate the unusual language I spoke until I was "re-educated"). My mother desperately tried to quash my true concept of reality. She kept insisting that I was the one that was moving. I told her I needed help with my philosophy class and started reading DeCarte, Sarte and later, my grandfather's favourite in its original Russian, Ouspensky, to her. On her death bed, I finally told her that I understood what she meant (I didn't tell her that I believed her!)! Do other people feel this way, as my sister has assured me my entire life??

[@Google_Does_Evil_Now]

Time we measure, and we use it to measure the speed of light in seconds. The weirdest thing is that we are an assembled collection of particles from the beginning of time but each form we are assembled into is for only a portion of time. How many previous forms have your particles been assembled into? Have your particles been in dinosaurs, volcanoes, the primordial soup? Maybe your particles were in several places at the same time, perhaps some were animals, plants, rocks, lakes, ocean, at the same time? Incredible that DNA can assemble those particles into every life form that has ever existed. And that all DNA are related. And that DNA itself is also particles. So what created DNA? These are a wonderful series of science videos that raise philological thoughts. There really are very very good.

[@cheetah219]

And whats crazy is that we can go go even beyond that. What created the particles, what do our particles lie on, what created that? What created the platform we are in...and on and on. It almost feels like there is an onion where we are creating worlds (simulations) to understand our own world and in the future, the simulations we create could create new simulations to understand themselves, etc. Its certainly possible that every single conscious being ever existing in a multiverse does not know their own origin and the particles that make up you and me are all pieces of the same past and future. Quite literally, our perspective is the year 2022, but our particles have already experienced the past and future and our minds are just moments of minute time. Assuming our theories are correct, we genuinely are nothing more than particles trying to understand ourselves. Its why i want to be cremated when i pass. Let my particles flow freely again and become something new. No need to keep then trapped in a box of slow decay under soil

[@jeffmacdonald9863]

"We are stardust." Also remember that your particles aren't even always the same. Most of our cells grow and reproduce and die, so we're constantly absorbing and shedding atoms. Many of the particles that make up you today weren't part of you months or years ago.

[@attilakovacs5803]

I like to think about the fact that in spite of these of these difficult and sophisticated considerations nature has just imprinted into us the simple notions of time and space. In our everyday life we don't need to analyse them, we can feel them, and even enjoy them, and that's a marvel itself.

@@christopherbentley6647 Okay. I mean that's a really unproductive, nonspecific, unnecessarily negative, oddly presumptuous, and frankly childish reply to a comment that was strictly positive on a video that's strictly educational, but okay.

@@christopherbentley6647 I don't disagree with you at all that people are getting dumber; they certainly are, for myriad reasons. I just think that this particular comment on this particular video was an exceptionally strange and out of place choice for expressing that opinion. Clearly people watching a video such as this are the type who have an interest in science and the pursuit of knowledge, and it's not like relativity and quantum mechanics are simple or rudimentary subjects that appeal to the general public. So how is it that you've deduced that comments of praise like mine are misguided by a lack of intelligence? Furthermore, how could you possibly presume to know whether or not people a generation ago would have enjoyed something like this if they were smarter? I'm not following your reasoning in the slightest.

I can testify to both of you as a consumer of television and radio from the late 1960’s that this production is of a level that was rarely or never seen for those 50 years. If there had been something like it, it would have been on public television and a lot of people would have enjoyed it. Johnny Lunchpail and Sally Housecoat then as now would likely have not tuned in.

[@zdcyclops1lickley190]

Science has nothing to do with magic. Magic is the opposite of science.

[@friendlyneighborhoodcrackh6059]

@@zdcyclops1lickley190 I was using magic as a synonym for “wonder”, though even if I weren’t, magic is in fact not the opposite of science. In fact, in just about any fantasy setting WITH magic, that same magic would be able to be defined as science within that setting. “Magic” in the fantasy sense defines a system of powers and abilities which are still dictated by some sort of “system”. Science, on the other hand, defines a method of categorizing and understanding the world around us. If that world had magic, the categorization and study of said magic would still be science.

[@kingstonbrown9517]

anyone who doesn't fully understand what entropy means thinks more entropy or higher is more chances and things that can occur and then think of low entropy as more certain and fewer options for something to happen example Imagine you have a deck of cards that is perfectly arranged in order from Ace to King for each suit. This ordered arrangement represents low entropy because there are very few ways to arrange the cards in this specific order. Now, if you shuffle the deck of cards, the arrangement becomes more disordered. There are countless ways to arrange the cards randomly, and this represents high entropy. It's much easier to achieve a disordered arrangement compared to the specific ordered arrangement. In this example, the ordered deck of cards has low entropy because it has a specific organization, while the shuffled deck has high entropy because it can be arranged in numerous ways.

When these questions overwhelm me late at night and keep me from sleep, I just remember the words of the doctor, it explains one thing anyway: “People assume that time is a strict progression from cause to effect, but actually from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly, timey-wimey stuff.”

If light itself cannot escape a black hole, could a black hole be spinning every direction at once? And if so, could that omnidirectional spin be a factor in how other things interact with one. Also, has anyone ever considered that we are inside a black hole right now?

[@moxxy3565]

Yes. The inside of a black hole would be a white hole, the exact opposite of a black hole. A white hole would look a lot like what we call the big bang, and as far as we can tell it's only happened once in our universe.

[@TheSnoeedog]

what would it even mean to spin in multiple directions at the same time? Take a marble. Spin it. Try to envision it rotating simultaneously in the opposite direction. Let me know what that looks like, because otherwise I don't think your post makes sense. Also, what does the spinning have to do with whether or not light itself can escape a black hole? What I mean is, if you started your post, "If light *CAN* escape a black hole, could a black hole be spinning every direction at once?" maybe the non-sequitur is more recognizable that way...? please advise...

I hope you make a part 2 to this, as the subject matter is abundant. Truly educational in all aspects, I had no idea that it was Galileo that first proposed relativity I thought it was Einstein. I particularly like how you give mention and credit to the unsung scientists.

[@jaydotclass7001]

It really is quite fascinating isn't it? The book "Dialogue of Two Worlds" is quite a famous book and the absolute definition of space and time is actually called the Galilean transformation thus showing how Galileo was the first to propose a theory of relativity. Einstein's Special Relativity relies on the Lorentz Transformation instead where a specific speed has to be held constant in every reference frame.

[@SofaKingShit]

I was so thrilled to get a new video from this channel which was immediately tempered by my inability to properly grasp the concepts as well as a good dose of existential dread. Still, l do actually prefer these channels and the distress that occurs when a channel creator overestimates my intelligence rather than the distress of their underestimating it.

[@curiosityxx]

I suggest not focusing on the theoretical reasoning, Rather focus on the implications of these concepts as a whole. There's simplicity in our complex reasoning, when observing it from a different perspective. Resulting in more efficient ways of defining these concepts

Mathematically a problem with Many Worlds is "where does the energy to produce the branching universes come from?" What many fail to explain is that a consequence of the equations properly applied is that there is no branching out, that's pop science: ALL possible timelines have always existed! That's much easier to understand if there is no time at all. The "Big Bang," the present, and the future death of the universe all happen simultaneously. Since we're trapped inside this universe and subjected to its gravity, we perceive spacetime. For an external observer, outside this universe, however, the entire thing is tiny and exists for a tiny instant. That would also explain dark energy: particles that seem to emerge from nothingness for a tiny fraction of a femtosecond. To us, they pop out of nowhere in the deepest recesses of our space. But for creatures trapped inside such tiny, fast events, they are entire universes, huge and lasting for eons.

[@stuartewoldt1513]

[@seditt5146]

Don't matter really because many worlds is just pseudoscientific nonsense. Its the definition of Scientific laziness. Its used because it is easier, not because of correctness. Newtonian gravity is easier also but we don't use that when attempting precise calculations as it fails. Many worlds clearly demonstrates much that is wrong with Modern physics. It is a disease.

It is always incredible to learn how things were discovered, especially so long ago. How the speed of light was discovered is so clever it blew my mind. If I was transported to 1600s, I don't even think I could of imagined a way to prove it, even though I know it to be true.

[@shethtejas104]

It didn't begin in 1600s. The great Sanskrit texts reached the looters of Europe by 1600s through arabia. It is in the very nature of white supremacists, especially those from Europe to put their brand name on every scientific discovery whether or not they actually had anything to do with it. They even don't spare languages. Little surprise then that they have given zero credit to India and given the entire narration based on their Euro centric narcissism.
