    The now same as zero not exist - just show me zero - yes there is 0.000001 but I will add one zero for endless time so you will never reach zero. The now is... time stop which means not exist.

    Objective now does not exist only in relativity. Theories like Einstein's can sometimes create an illusion of false reality based on unfalsifiable experiments. Because our knowledge is rooted in these false maps of reality, we cannot comprehend the gap between quantum mechanics and relativity.

    The problem is how speed is measured. It is measurement problem. 186000 miles/second. This per second/minute/hour/days/weeks/years is the problem. Distance we travel, we can see the for example 100 meter dash run, but TIME! Is so subjective ill defined. Until we know what is time, how we define time, we may never know light properties. May AGI will guide us soon 😅

    YES!!! When I see a new upload from this channel, I get so happy. I used to be happy and excited about life when I was studying physics in college. Taught high school physics after that and had so much fun with my classes. Unfortunately, the reality of low teacher pay, new family on the way, and my other option to make more than double if I work with computers, I went back to my tech job. Now I am almost always depressed, feel like there is no hope and nothing to look forward to in life any more. That being said, whenever I see these videos it takes me back to my happy place. Thanks for all the effort you guys put in to put these out. They mean the world to some of us.

    Can you teach at a higher level, like at a bustling university, sometimes part time instruction is needed which can pay well enough to fit in some part time teaching. Even offering tutoring can help fill that desire to teach? Even when I did teach there were special needs students that need additional help and can be very exciting to see how you can reach them and help them along. I am fearful that this next generation is really going to be a struggle with the necessary people interaction skills.

    The section towards the end would be even better to include how the "Brain makes decisions before you even know it" - published in Nature on April 11, 2008. Brain activity predicts decisions up to 10 seconds before they are consciously made! This directly impacts our sense of having free will - actions that we take are set in our brain - and can be predicted by instruments - before we are aware we “decide” to take that action.

Just absolutely screeches to a halt so we can all have a snail race of consciousness trying to use the stream of absolutely bonkers information to output something useful to continue existing in what it sees as a valid state of now.

    Some angels once left their dimension to enter ours, they had no problem dealing with our 3 dimensional worlds 4th dimension. They came to mate with the women of our dimension and did so. IDK If you will consider the forthcoming children aliens or not but they had no issue with time either. This information comes from the book of Genesis with a few refraneses in other books of the Bible. As for space aliens originating from within our own dimension I have 0 credible information to offer you my friend 😢 As for those particular aliens mentioned above they are locked away for now but the children they produced appear to have become what today are known as Demons and very likely present themselves as space aliens among other cleaver cons they do so love to run on us humans.

    General relativity and quantum mechanics will never be combined until we realize that they take place at different moments in time. Because causality has a speed limit (c) every point in space where you observe it from will be the closest to the present moment. When we look out into the universe, we see the past which is made of particles (GR). When we try to look at smaller and smaller sizes and distances, we are actually looking closer and closer to the present moment (QM). The wave property of particles appears when we start looking into the future of that particle. It is a probability wave because the future is probabilistic. Wave function collapse is what we perceive as the present moment and is what divides the past from the future. GR is making measurements in the observed past and therefore, predictable. QM is attempting to make measurements of the unobserved future and therefore, unpredictable.

    Good one. I had figured QM and GR cannot be ocmbined because QM is quantum and gravity is not. Gravity is generated/ Spacetime is curved as a resolutionless spline between quantum units of mass. I also do not believe a theory of QG will ever be formulated.

    Additionally, the random nature of quantum fluctuations is what gives us biological organisms our capacity for making choices, or the illusion of free will. Maybe it's better to say that the randomness prevents us in any case from predicting an accurate future. It hides our inescapable fate in a forest of fates.

    You can`t give an answer withouth looking at your Watch therefore the Question "what time it is" already asks for a future time which is the time they hear your answer and because time went on after you looked at your watch and comunicated it, it is in the past. So they ask for a future time which is in the past as soon as you tell them the time, i can see why this makes you flustered. The solution is to allways round up since no one asks about seconds anyway.

    46:37 interesting. i have a background in animation and immediately picked up on the lag, as it's something i've been trained to compensate for. in this situation I would fix it by making the flash happen a fraction of a second before the red square reached the center position. i saw the illusion but still interpreted it correctly based on past experiences, like a baseball player swinging at a ball. i wonder what other illusions we can train ourselves to interpret differently than how our eyes/brain sees them.

I have no idea how many frames the flash was actually on screen, though, and the second frame could have just been my brain lagging to process information and making an afterimage. What did you see?

    @fieryeyez6607Ай бұрын

    Thanks for entertaining thought provoking video. @ 24 minute mark you're wrapping up the either - photon experiment. Two questions for ya on that.... 1. In all of these years since, has no one noticed or mentioned that every single piece of equipment used is moving at the same speed in the same direction through the same medium regardless of what that medium was allegedly made of? I explain; it is not the case that only one target moved and therefore one photon traveled farther (through more either even if there was an either). Both photos traveled exactly the same distance in exactly the same time. Conclusion: with or without any either, (as well as with or without any constancy of light speed i might add) the result is exactly as should be expected. Everyone is obviously aware that whatever time was lost chasing that target that's moving away from the mirror is recovered on the return trip to the mirror witch is now racing tward the photon as it returns, aren't they, it's not obvious? Simplified.. if all involved equipment (including the photons) is/are moving in the same direction and speed it's exactly the same as the entire experiment being done sitting still. Just like the boy bouncing a ball while riding in a train, he doesn't need to run 60 miles an hour to catch up to the ball in order to hit it each time because evening (including himself) is equally affected under equal forces. ( a closed or controlled environment where ALL relevant "factors?"are under the same influences) 2. Right? Take the previous example, have the sailor hit 2 balls at the same time, bounce each ball off of (oh i dint know let's say) 5 targets all at equal distance and in the same directions. 😂 both balls still hit the ocean at the same time regardless of weather there is any either or constancy law governing the movement of golf balls present. Please don't just tell me I'm wrong. I really need to know where I'm wrong, I'd love to hear why and be able to agree with brilliant minds who obviously are buying into this very old conclusion. It's frustrating to see things in this field as simply obviously misguided conclusions. So please help if you understand my position but disagree because, I'm fairly convinced of my observations and the conclusions I've drawn.

    the tickrate at which we perceive "time" is really a frequency generated by the brain and we can influence that with cognition, this is exactly what derealization and adhd do: they affect how fast we perceive time. This tickrate also varies based on each species and offers a broad range of variation for natural selection to take over more efficiently as a species. It is the eternal great cycles of Samsara, entropy oscillating back and forth on multiple wavelengths simultaneously. Our experience of life going from order to chaos is really biased by our existence at only one side of the larger oscillations of reality. In fact reality is absolutely relative. Time is an illusion, entropy is a fractal of cause and effect, tied together on each end by causality. It is merely another dimension we experience, while riding an energy that oscillates across this spectrum.
