Video transcript

in the last video we tried to relate what 13.7 billion years really means by compressing it to ten years which is still a pretty long time at least from our perspective and we saw that these huge periods of time everything that's happened since the Declaration of the United States Declaration of Independence it all gets compressed into just five seconds and that's you know that's that's not much when you think about ten years I mean ten years you could wait around a lot that's that's a huge amount of time so hopefully that put things put things in perspective a little bit what I want to do in this video is kind of do the same thing but relate the 13.7 billion years if that were a distance or the length of a timeline how big each of these periods would be so just to start off the timeline I'm recording this in high-definition right now there's there should be twelve hundred and eighty pixels wide depending on where you're watching it so maybe you're watching it on a high-def TV if the timeline was the width of my screen right over here if the timeline was the width of my screen here so if that was 13.7 billion years from there let's say this is the beginning of the universe and this is our present time if that was 13.7 billion years the amount of time that humans have been on this planet who 'men so the people who look and think like us the amount of time that we have been on this planet will not even be a pixel this little dot I drew is multiple pixels the the amount of time we've been here would not even be a pixel in fact a pixel and that dot I drew here is about four pixels but a pixel just one little pixel on my screen would represent 11 million years 11 let me scroll over it would represent 11 million 11 million years so if this was the timeline the dinosaurs the dinosaurs would have been extinct about 6 pixels from the end so it would be right about so 6 pixels from the end is where the dinosaurs would have gotten extinct and the amount of time that modern humans are on the planet wouldn't even register here be one twentieth of that pixel over there in fact we could if we just expanded that very last pixal if we were to expand that very last pixel I'll do it in yellow that very last tiny pixel that you can't see if we were expand that to the entire length of this screen again if we were to so if we were to just expand just that very last pixel so I'm I'm saying everything on this yellow line could be contained in that very last dot right over there then every pixel in this then every pixel on this would still be would still be eight thousand eight thousand years so the entire period of time that humanity has been on this planet on this scale on this scale so we've broken out this little tiny pixel here all the way out here to hundred thousand years that's on the order of about 25 of these pixels so 25 of these pixels would be something like something like that not probably not even that not even that so 25 pixels on the screen at least at my resolution is about that distance so this is the fraction of just that pixel that is the amount of time humans have been on the planet if you want the time since Jesus it would be 1/4 of a pixel on this yellow scale on this yellow scale it would be 1/4 of a pixel and the amount of time since the Declaration of Independence would be even a more even a more miniscule amount of time so that's one way to think about it but these timelines to some degree also don't give justice so another way to think about what if we had a timeline that that's stretched from here where I am in the San Francisco Bay Area if it stretched 1,300 kilometers to to Seattle so if this thing stretched 1,300 kilometers all the way to Seattle then how so this thing the Big Bang would be sitting in Seattle this would be sitting in Seattle the the universe well the universe the the formation of the earth and the solar system this would be about about 200 kilometers away a little over 200 kilometers and in the direction of Seattle I don't know that would get us in probably some part of Northern California with redwoods and and whatnot but just to give an idea of 200 kilometers that would get me from where I am at near the coast of California to about the Nevada border so still a pretty good distance relative to the entire time line the the dinosaurs the the the last land dinosaurs when the dinosaurs when the earth got hit by an asteroid this so remember the our whole timeline now stretches all the way to Seattle this event now would have only occurred this event would have only occurred about 3,000 meters away about 3,000 or maybe I should just say three kilometers away or roughly about two miles so that still seems like a pretty good distance but remember our timeline stretches all the way to Seattle from the San Francisco area so it's a pretty big timeline so this is already a pretty small distance but it gets even smaller australopithecus this right over here this when they were roaming the earth three million years ago this gets reduced to a little bit more than a football field about 150 150 meters not kilometres let me write that in a color that you can wear there's some contrast 150 meters is what it was where so 150 meters in the direction of Seattle if that's the timeline that we're talking about and then the first humans even shorter it's only going to be 10 meters 10 meters of this timeline that stretches all the way all the way to Seattle the birth of Jesus birth of Jesus two thousand years ago two thousand years ago would be 10 centimeters 10 centimeters on a timeline that stretches from San Francisco to Seattle and then finally the Declaration of Independence the American Declaration of Independence would be one centimetre one centimeter on a timeline that stretches to Seattle anyway I don't know if that made it if that put things in more or less perspective but but it was worth giving it giving it a shot
