When Will Time End? (Version 1)
Watch the EXPANDED and UPDATED version on...
• When Will Time End?
It now seems that our entire universe is living on borrowed time. How long it can survive depends on whether Stephen Hawking's theory checks out. Special thanks to Ivan Bridgewater for use of footage.
Time is flying by on this busy, crowded planet... as life changes and evolves from second to second.
And yet the arc of human lifespan is getting longer: 65 years is the global average ... way up from just 20 in the Stone Age.
Modern science, however, provides a humbling perspective. Our lives... indeed the life span of the human species... is just a blip compared to the age of the universe, at 13.7 billion years and counting.
It now seems that our entire universe is living on borrowed time...
And that even it may be just a blip within the grand sweep of deep time.
Scholars debate whether time is a property of the universe... or a human invention.
What's certain is that we use the ticking of all kinds of clocks... from the decay of radioactive elements to the oscillation of light beams... to chart and measure a changing universe... to understand how it works and what drives it.
Our own major reference for the passage of time is the 24-hour day... the time it takes the Earth to rotate once. Well, it's actually 23 hours, 56 minutes and 4.1 seconds... approximately... if you're judging by the stars, not the sun.
Earth acquired its spin during its birth, from the bombardment of rocks and dust that formed it.
But it's gradually losing that rotation to drag from the moon's gravity.
That's why, in the time of the dinosaurs, a year was 370 days... and why we have to add a leap second to our clocks about every 18 months.
In a few hundred million years, we'll gain a whole hour.
The day-night cycle is so reliable that it has come to regulate our internal chemistry.
The fading rays of the sun, picked up by the retinas in our eyes, set our so-called "circadian rhythms" in motion.
That's when our brains begin to secrete melatonin, a hormone that tells our bodies to get ready for sleep. Long ago, this may have been an adaptation to keep us quiet and clear of night-time predators.
Finally, in the light of morning, the flow of melatonin stops. Our blood pressure spikes... body temperature and heart rate rise as we move out into the world.
Over the days ... and years... we march to the beat of our biology.
But with our minds, we have learned to follow time's trail out to longer and longer intervals.
Philosophers have wondered... does time move like an arrow... with all the phenomena in nature pushing toward an inevitable end?
Or perhaps, it moves in cycles that endlessly repeat... and even perhaps restore what is there?
We know from precise measurements that the Earth goes around the sun once every 365.256366 days.
As the Earth orbits, with each hemisphere tilting toward and away from its parent star, the seasons bring on cycles of life... birth and reproduction... decay and death.
Only about one billionth of the Sun's energy actually hits the Earth. And much of that gets absorbed by dust and water vapor in the upper atmosphere.
What does make it down to the surface sets many planetary processes in motion.
You can see it in the annual melting and refreezing of ice at the poles... the ebb and flow of heat in the tropical oceans...
The seasonal cycles of chlorophyll production in plants on land and at sea... and in the biosphere at large.
These cycles are embedded in still longer Earth cycles.
Ocean currents, for example, are thought to make complete cycles ranging from four to around sixteen centuries.
Moving out in time, as the Earth rotates on its axis, it completes a series of interlocking wobbles called Milankovic cycles every 23 to 41,000 years.
They have been blamed for the onset of ice ages about every one hundred thousand years.
Then there's the carbon cycle. It begins with rainfall over the oceans and coastal waves that pull carbon dioxide into the sea.

I have seen this (Version 1) over 20 times and it is still my favorite documentary. The writing, music, and comprehensive view of time, space and dimension make me smile.
I was looking for this forever!
After reading a lot of the comments on several of these videos, I have to say I feel really bad about the future of our species. On a positive note, thank you spacerip for the amazing videos!

you feel bad, why?
When we die, it is finished for us.
Great job guys :) . Except of truly great narration you got also great music playing in the background. Well done !!!
Thank you for not putting ads on this.
Awesome video. Time definitely seems to be a human invention in its conventional sense. As a universal property, I think its on a whole other level we can barely begin to understand. Its really amazing how insignificant we are in the grand scheme of things.
There is no time, there is only now.
This kind of thing makes me love science more and more.

this isn't science. you don't even know what that word means, apparently. to you, science is nothing more than another religion, complete with its priests and Sunday sermons (this video). shame on you.
Nicely done. Also a nice reminder of how insignificant humanity is in the scheme of things and how the daily news cycle… A meaningless blip.
I have a theory that " the Big Bang" was a reset of the universe. The narrator said that time could be resetting itself over and over again. So what if there was life before "the big bang" and it was all destroyed. What if there was a war between the universe and someone destroyed everything knowing it would all come back and we could get a second chance?. "The war doctor" from doctor who did something similar to his planet in the show and so what if someone or something did the same thing to the universe with a big bomb capable of doing this. (Please fell free to prove me wrong or if you want you can expand on this theory and try to prove it. But if you do prove it and become famous for finding this out just mention me)

The nature of the universe is infinite. Infinity has no beginning and no end - infinity is instantly infinite. Like a singularity in that everything that existed, exists and will exist is always there - every possibility of existence. In other words - in relation to infinity of time, the chance that you already have written the above comment, is 100%. Welcome to infinity. ^^

***** Time is the infinite factor of the universe and we already know that time is relative. There are several forms of infinity, e.g. an endless cycle of becoming and passing away. Every new becoming is a variation of the former - another possibility. This means that every thing, every possible combination of existence will emerge 100% in relation to infinity of time. The universe will die (sucked up by the final black hole) and then when nothing is left, the last black hole will collapse in a huge explosion - a new big bang - and the process starts again.

Oh no way, that's exactly something I was looking for, thanks man !! :D
Your videos should be a TV series!
It may be dark and depressing, but its nice to watch and listen to this late at night with homework to do.
i saw this a really long time ago when i was younger, i thought i imagined it but i finally found it
Well said mate. Smoke away and see things from a different view :) happy blazing!
I love this channel.
This version is far more better than the new one!!
Well, this was pretty enlightening!!
you sir have earned yourself a subscriber
Correct me if i'm wrong, but what you've just said is, we arrived before the big 2 minutes BEFORE the big bang on the calendar. Nice one bro
if you only could feel my heart beat when i listen 2 this
Ah, okay! that answer is pretty satisfactory in regards to my questions. That leaves only my question of what spawned that infinitely small dot, but i dont want to turn this into an existentialist conversation lmao. Thanks for the information Lazar Lukic :)
Finally a good answer! That's really cool if you think about it that way!
Thank-you for the information, well done Bravo!!,
Indeed site but with the certain fragments would spread out of this collision have you ever considered does it actually fly like a bullet or does it spin and rotate flying off in the direction
being how time is as a result of thought time will end when thought ends
Objects are not flying through space away from us, they are stationary within space but space itself is scaling up. As the scale shifts up, you would expect things further away from us to be moving away from us at an excelerated rate. We in fact do see this. Also, the angles and perspectives match as well. We measure from points outside our solar system from "voyager" and we find that the expansion is from every perspective point we measure from. The only physical explanation- expanding universe
great video
If I watch anymore of these videos, my brain will implode.
insightful. very insightful
It is theorized that eventually the universe will experience a heat death... a state of maximum entropy, but that's so far in the future I can't even conceive it.
Oh, and heads up- the redshift / blue shift Doppler effect is provable in the lab. How do you think we should interpret red shifting galaxies? Also, FYI the expanding universe doesn't mean there was a Big Bang. We have no way of knowing when the scale factor began expanding. But steady state theory is old hat and the Hubble diagram (based on provable observations and predictions) makes that obselete.
the very goal of our existence is to learn as much as possible and survive until the next cycle or at least pass on some knowledge. .
Now, because matter is in violent motion simulating rest and balance through violent motion! The inward absorption and outward emission of EMR is forming antimatter matter annihilation forming + and - electric change and electromagnetic fields as time unfolds dissipating gravity. In the future Heisenbergs limit will be required time cycle for quanta to exist. Every moment the wave-function is collaspes now reforming+/-eXploding into this enormous collage that we experience as the current moment.
Time does exist, as a mere linear interpolation between causal chains. It is simultaneously zero and nonzero, however, depending upon your frame of reference.
Humbledudedonthate, the way that they know that is because of "hublble's graph" which show the movements of high redshift objects and their speed in relation to low redshift objects and their speed. Ie. everything is moving away from everything else and things farther away are moving away faster. This shows that space is expanding and at an increasing rate. That rate is steady and can be charted as Hubble did. If you follow the movements backwards you can arrive at the time in which-
I wish these videos were longer. They just feel too short
i'm pretty sure you're high and time never freezes or else we would definitely notice it and the universe is expanding past the speed of light which shows that time has never frozen.
Very interesting documentary even for us non English native speakers.
Actually, thinking about it, the candle with the hour-markings probably wasn't the first measured unit of time. On reflection, the day was already in existence, and so was the year, so events could already be measured by counting natural event cycles long before we invented candles or any other devices for measuring time.
damn "A River of Tears" from doctor who would be epic along with this vid
Let me ask you this if time stopped what would go on then becouse if evreything stopes how will we restart if not somthing go ons?
can anyone tell me the name of the main theme song in this video? I've tried to find it by the info in the credits but I still can't find it :
Dave Brody is perhaps my favorite narrator from SpaceRip
@ eminaevangelion - it's certain the universe is both expanding and cooling - that's how we know it was both smaller and hotter in the past - figuring out the rate of cooling and expansion and the current size and temperature lets us work out how long ago the universe was very small and very hot - the point at which it was infinitely dense is what we call the big bang. Current theory doesn't predict the universe will ever contract again though.
Does anyone have any idea (scientific) as to what was there before the big bang theory, or where space, time, or matter came from?
This has all been worked out but its too long to cover here.Turns out its the way time dilation contracts matter in a way thats indistinushable from space expansion,turns out to be the same thing.Every black hole ends up expanding the space around and in it giving the the same pridictions as given for inflation theory if you could measure from its inside.Theory has been argued to its end on Usnet.Never caught on because of other factors.The web site is down now so ask if your interested.
Great video really enjoyed it some big numbers. Other videos like it suggest the universe after all the stars die out ,black holes evaporate the universe will just be cold vast empty darkness. I doubt any recycle event. And I am ok with that I am a part of the Universe & can accept things as they are without fear.
Time is a measurement of motion for the purpose of identifying a quantitative relationship of the observer to the motion.
nice vid
although perceived time is just our memory, which as far as we know could finish at death? but yeah, you both are right, sort of.
What is the soundtrack used for this video?
That’s the end of our universe, and yet that’s still far short of forever
And what would cause the gravitational acceleration of matter at the high red shift areas?
what is the name of the music on time 3 minutes in the video ?
Does anybody know the name of the song that starts at 20:20?
Well, would've like to think the energy black-holes as they reach out and slowly merge with other black-holes to form bigger and bigger ones would've been part of what causes us to collapse back to the center and be the rebirth of a new universe but...yeah this really gives me a different picture now.
Well said.
What stuff do you question specifically? Maybe I can help clarify!
The soundtrack looks like the music in some observer kinda video In TribeTwelve
Disciple derived from the Latin word "discere" which means "to learn" and "discipulus" which means pupil. Discipline is derived from the latin word "disciplina" Which means a teacher. So, the derivation is from nearly the same source, but one did not come from the other.
7:02 chills of awe.
hahaha your comment made me laugh so hard and i agree with you.. i always get that "wtf is going on right now !!" feeling as i reminisce about the universe :D
Ok found the song, its called: "My piano sings" by Tryad
What is the song in the background at the end before the credits?
I agree with you completely.
soooooooooooo humbling
wait what???!! im buffled with those numbers! i was mind blown... i feel like im a spec of dust in terms if size and time in this univers...
the reason conceptualised time and started measuring it would be because of the simple pbservation that we all are born and we all die so we are not ever lasting and the gap between the life and death needed to be understood and quantified
that something also must have properties (intensive, extensive)
The observation that motion is one type of relationship between entities is what gives rise to the concept of time. It's in this sense that time has meaning. The entire concept of measurement including time, presupposes an observer who measures. Time can't be applied to the universe as a whole because the universe doesn't exist within a larger context. The universe doesn't exist in time or space. Time and space exist inside the universe. The universe is eternal and outside of time.
Cycles are all around us so I believe that this is not the first, last, or only universe. Just like day turns to night and night turns to day and how summer turns to winter and winter turns to summer, another cycle will begin. It might be a totally new universe with new matter and whatnot. But I really don't think that it will ever end or that the cycle ever began.
This is so damned amazing.
Wow.. Time is so long, yet we have so little of it.
Can someone tell me, in terms of 13 billion years, how long is say 20 years in terms of the age of the Universe? As in for us 20 years is a pretty long time, but in terms of the entire time - is 20 years the equivalent to minutes, days, or what?
"Space within the universe is just infinity within the universe". I think this might be the best thing I've seen... you seem to know what you're typing about :D. By the way - Do you believe we can make our own choices or is it already chosen by faith?
Aye as I said its a freaky, interesting, amazing and beautiful concept, it is the fundamental building block to everything yet, may not even be "real"
Clicks on video -> Thinks: "there must be a holy war going down there on comment page on a vid like this" -> scrolls down -> "Everything is going as I have forseen *sinister laugh*"
No matter where you observe objects from, the universe is expanding from that point of view. This is because the scale factor is shifting upwards. If you disagree, show me your research proving it.
But fortunately, someone got smart and 11 dimension space time is starting to make more sense especially after seeing something like this. Energy coming to rest here is energy becoming kinetic in an asynchronous super positional universe(mirror universe but not quite mirror). But it goes deeper, much deeper like a chain of universe forming and we are at a specific phase and moving sideways along this chain of universes, some closer to the beginning while others closer to the end.
I couldn't have explained it better myself
True what he says : Time is our perception of the move of dimensions towards gravity.
Two things I don't understand: #1, when particles well up from the vacuum of space that would normally annihilate eachother on a black hole, Hawking says that sometimes one will escape. If so, where will it go and what will stop the black hole from reabsorbing it? #2 They say the big bang created the universe, and that it came from a tiny point. Sounds exactly like a black hole to me. If a black hole reaches a certain mass, could it erupt in a bang? Could they in fact BE big bangs? If not, why?
Is the time of something one light year away happening now or one year from now?
well said :)
Original narator and my hero
Anybody know the music at 06:20 ???
Before big bang all matter that ever existed and all energy were compressed in one infinnitly small dot. Theory is that at the begginning there were 4 spacial dimensions and when big bang occured one dimension of space became time dimension. Sorry for my bad English.
You guys sure put a lot of "time" into this...
Seeing as the accepted theory is that both time space were created in the big bang, then time began 13.5billion years ago. It is relative, but that doesn't mean it's not measurable from our own perspective.
Whose to say everything you've ever done didn't happen? Theres only now, and no before
dude..... that really made me laugh. I am sure the vodka had a part in it.. but still funny!
Time is how we measure the result of the continuance of entropy, caused by friction of things in motion.
Time will never end, only the human concept of time will end when the time of humans end.
20 years is a millisecond...not even that. Carl Sagan put the entire existence of the universe on a year calendar. Where January 1st is the big bang, and today is December 31. Humans have been around for about 200,000 years I think. On that calendar, humans arrived at 11:58 pm on December 31st. Now that is quite humbling...
Mate i actually completely agree with you there. I am sorry if I am coming across as a science fan boy I just get so frustrated. But yeah I think are universe could be something small in something much much bigger.
