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.

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.

[@elroyfudbucker6806]

I think, the real question is, "is there a past or future?". Arguably, the "now" is all that can be said to exist since it is the only thing that can be perceived. The past has already happened and is no longer present, and the future is an abstract idea of the progression of now. Neither are tangible, only the "now".

[@danielpaulson8838]

The “Now is the only time” isn’t a science idea. It’s a spiritual one. Don’t mentally live in the past or future. Live in the now. We know time is real. We start out as infants and grow to old age. If we’re lucky. The Universe has been emerging to its present state due to long passage of time. There is a real past and future.

​@@RealDonfromBroward It is weird the dilation of time that happens around consciousness or observation, there is nothing else, for 14. Something billion years and then the superposition of all the states of every piece of matter collapses with an observer.

Probably the best science channel on KZbin... Excellent!

Gone is gone and you never get to know youve gone. Thats the beauty of gone. Good luck it is fast and painless to point where youve gone

To everyone here, I implore you with all my heart to check out RUSH's song, "The Garden." "The future disappears into memory, with only a moment between. Forever dwells in that moment. Hope is what remains to be seen."

[@awillingham]

I love rush but have never heard that one, what a great song.

[@Ultra-Luminary]

Thanks! I am doing that now🙏

Wow ! Such profundity ! Basically ; word salad . A series of words which , when analysed , actually turn out to be meaningless drivel. Similar to Alan Watts Buddhist shtick ?!

"One flick of it's mighty fluke.." If I had a nickel for every time I heard that passed around in a conversation.

45:07 as a kid when I discovered this I always thought of it imaginatively as if I was temporarily freezing time

I like the voice it is a lot easier to listen to than others . His pronunciations are easy to digest! Thank you.

2:03 from what I know pigeons only see in 2D as the fields of vision of their eyes don't overlap. The reason that they flee in the last second is that because of this they don't notice the imminent collision earlier. And you do often see dead pigeons on the road, so they do get run over. However this is usually not on city streets, as in the city cats are slow enough that pigeons can escape even if they react only if the car is at a close distance to them.

[@jonathanh222]

Not 2D. That would make it impossible to traverse space. Their eyes position means they observe non-intersecting cones of vision, but their vision is good. What you mean is how they achieve depth perception, which is just different from how we do it. You can google this for a more in depth explanation. No creature sees in frames either. This perpetuates the myth that humans can only observe up ta certain amount of frames per second, which is just bollox. I'm flabbergasted that a channel of this quality would be so incorrect

[@rfvtgbzhn]

@@jonathanh222 from what I know the cells in the human eye has some kind of refresh rate (this is why you see flicker on CRTs with low refresh rates and wheels sometimes seem to rotate in the opposite direction). However the rate is not the same for everyone and the human brain usually combines a few of these "frames". Thus can explain some optical illusions and also it was shown that if you replace a single frame in movie with a different image, it isn't noticed consciously (but I think there is a controvery if it can have sublimal effects, like more people buying coke if you replace a frame with a picture of a coke in a movie at a theatre). So for short: the human eye has a refresh rate, but the brain doesn't process visual information frame by frame.

[@jonathanh222]

@@fabio.1 That is question of your brains ability to process images lasting for just milliseconds, but you can easily tell the difference when a monitor delivers say 100, 200, 300 etc frames per second. You will be able to tell the difference. At what point you lose the ability to process / remember any one frame among these is up for debate. Point being, eyes themselves are not limited to fps, that concept is only applicable to measure how fast monitors are, not how we perceive the world.

One of the best videos on YT. Inspires me to read spectroscopy books.

Anybody know the song that begins playing at 17:37? I think based on the video notes it’s by Yehezkel Raz but I can’t seem to find it in his catalogue.

[@geoffsonik6964]

And the song that plays at 21:45?

[@brianzomorodi]

The enigma of Time beautifully explained. Bravo.

[@axle.student]

Thank you. Very well made video :) . 46:55 I find it interesting that I don't see the lag. It appears directly below the red. I am trained to understand this so maybe my brain re-compensates from my education and training. > Second stairs set works as expected :)

[@Penny-16]

Your 3 channels are some of my favourites. I always watch them more than once. Just fantastic. Idea for a 4th channel: The Entire History of Civilisation. I’d love your take on it. Or will it be part of your humankind vids. (Will and Ariel Durants series ‘ The Story of Civilisation’ are my favourite books.)

[@wadejameskennedy4495]

thank you. my consciousness expanding is most pleasurable.
