The nature of time - Boundaries of the Knowable (7/10)

[@Homeostase.medicina]

This is definitely the hardest video to understand of this series hahahaha! It's kinda hard to view time from such a different perspective after years seeing it as separated from the 3D. It really impresses me how Eistein was able to come to this conclusion by himself! True genius!

basically, the faster you are, the less you age

[@kapplejacks22]

Has anyone ever noticed that when you dream, it sometimes seems as though you've been dreaming for hours, but when you awake, you realize that you've only been dreaming for an hour or less?

[@JohnDoe_69]

Yeah and? There's always the coocoo heads with their hoodoo "theories" in the comments...

[@noahian3215]

@@JohnDoe_69 well what’s your theory?

[@nd264u7]

I heard dreams only last s few seconds

[@swaroopa1965]

this guy is amazing!

[@joxnjoxn399]

He has a good sense of humor right? Not to mention being a great teacher

[@GENCE.01]

Confusing, so much so that even Professor Russel gets confused. Thank you for all of the videos, I'm loving it, but this episode was the most difficult to fit in my head, until now. I already knew the theory of Einstein that said time is different with speed, but it is still difficult to understand how speed can change time...

[@life42theuniverse]

If the viewer runs around or watches at 0.5x the program takes longer...

[@NorthofNorthIsland]

I like all the episodes, very Interesting and thought provoking , and I love the humour at the ends :)

[@clintonraubenheimer5879]

10:38 could not help laughing because right up to that point I was pausing the video to wrap my mind around what he was saying

[@DiGiTaLdAzEDM]

After thinking quite hard about time, I came to the conclusion that time is change, or rather the perception of change. What is change? change is the conscious experience of the sequential unfolding of that which IS. At some level of 'reality' all events from the largest to the tiniest exist simultaneously--timelessly. Time is the experience of that reality manifesting in a sequential manner. That's the best I've come up with so far anyways.

[@SeladorCellardoor]

The problem I have with the idea of the block universe is as follows: It seems to me to be quite plausible that if time is literally part of the whole continuum, then past, present and future events are there, frozen, as an existing part of the universe. But if our experience of time is merely a psychological mechanism, surely it requires the passing of time for the mental experience to happen. Like all theories of time this seems to need a meta-time to work.

[@3fast5you]

If I swing my arms around while spinning in a circle, will that make my arms older than me?

[@JoeyCbr]

Why have I only just found this guy, this is really well put together

[@Sorya-gf7qw]

watch videos at 2x speed for some time and then read some book or think it will appear that your mind is thinking faster for some time . ( almost same thing 1:15)

[@qcon81]

you r the greatest. u just awoke me. thanks for the videos professor!

[@TearyEyesAnderson]

In that way 'Time' is what is observed by the motion, each person can agree that there was motion but not agree exactly by how much, or the speed of that motion, since it will seem to have changed depending on the perspective of the observer. However the 'Time'/motion is either moving forward or at rest, in which way time could possibly stop if the speed of light or, the absolute zero were reached. One no motion and no time, the other change couldn't catch up to the motion/'Time'.

[@Odair_Fernandes]

Although I have seen many videos talking about this subject, I have to admit that this video brought me new things to think about it. Great!!!!!!!!!

[@Larro4]

Great video!

[@TearyEyesAnderson]

@feliztex I think it's been reported that even astronauts in orbit and satellites show 'Time' keepers slow down, and when they come back to Earth they do pick up speed again, but just to the amount that they slow down, so they and their clocks are still behind when they get back to Earth. As if there is something slowing down the atoms while going fast, and like Absolute Zero, move less and less when they go in a straight line and 'Time' slows. I give my theory of 'Time' above.

[@TearyEyesAnderson]

I see 'Time' as motion, not as a fourth dimension, but as motion with in the 3 dimensions. Just like if u see a person on the 3rd floor of a building at the corner of 1st & 2nd street. Each obsever will see that person in slightly a diferant way as 'Time' is seen in a differant way by observers. At point a, b, & c there is a dot, & the next instant the dot is somewhere else it is motion/'Time' because the dot isn't where it was before. If it moves back it is still motion & continuing onward.

[@Sorya-gf7qw]

Assume that guy in craft makes a phone call to guy on planet , what will happen then ? so does space guy says - hey buddy slow down I cant understand a thing .

[@namahshrestha3226]

Just like the reduction in relative distance. I assume there will be something that'll make things seem normal.

[@twistedbasser]

Thank you so much for the ending to this video. For a few years now I have been questioning the fundamental implications of time. I seem to be settled on it being rather more a unit of measurement than a building block of reality. Our experiences of past and future are but illusions created by our consciousness to try and explain how our lives have beginnings and endings. There is no past or future, they are not real...... Seems that perhaps our understanding of time going faster or slower to an observer may be simply an example of perspective, or as Einstein would have loved to put it.. relativity? Oh wow, then again perhaps our struggle to understand time changing for an observer is related to the classic struggle for a unifying theory.. Perhaps time changing relative to the speed of an observer is related to the quantum theory of how light itself can change from being a wave or a particle depending on observation..

[@bajovato]

Same here

[@xFlared]

imagine how slow the time would be if you were in the part of space where all the material is millions of light years away. :O

[@shrinik1969]

Cool ... where is zero of time axis? Big bang? The marking of past, present and future has to identify the reference point. According to who? There is no answer to the question "what is the time in the universe now". And the point of "now" is itself has to be with respect an observer. Where do you put (0,0,0) of space 3d?

[@dancingtrex6614]

Please reply back if you are not dead

[@deathing]

@NKblade On the contrary, 0,0,0 being everywhere is only true if space is infinite. The conservation of momentum means that the universe's center of gravity has never shifted, that is where all matter and space emerged from, making the center of the universe and the 0,0,0 point

[@Tiggermk4]

Uh...if all motion is relative, then is saying that someone is moving at x% of the speed of light not a nonsensical statement , except in relation to another observer ? That being the case, does that not mean time itself (as well as motion) requires an observer to make sense? P.s. Love the series

[@NEMOPMORPHY]

I’m here because of the Illuminatus Trilogy by Robert Shea and Robert Anton Wilson

[@Quazi-Moto]

I SO dig this guy =-D

[@aqwertgbvcxz]

There is a difference between relative time and absolute time. Relative time is space dependent. Absolute time is not space dependent.

[@Moonsabie]

i was reading Kant in a sunny room today and i was observing the shadow cast from the mound of one page to the face of the another i Noticed when the page is flat the shadow does not move but as i bend the page the shadow starts to move Much faster in fact then the hand that bends it inward .. then for the first time age (27) it Occurred to me anything that Moves has a curve !Our universe is made up of Curves! everything.

[@Hellacool66]

@Liusila that is soooooooooo crazy!!!!!!!!

[@SeladorCellardoor]

Yes, but the phrase 'temporal becoming' implies a meta-time.

[@deaddirt3214]

Time is relative to the observer

[@3fast5you]

Wow, mincfuck! My mind is all blown, this is amazing.

[@youcrackers2]

lmao at the ending

[@Liusila]

@Hellacool66 no but you could age much slower *mind explioooosiooons*

[@Hellacool66]

could i get younger by going around the world twice as fast as the world... ? obviously not running..

[@Sineburst]

the block universe... Neincreft
