- the purpose of this video is to just begin
- to appreciate how vast and enourmous the universe is;
- and frankly, our brains really can't grasp it
- but we'll see in this video is that we can't even grasp things
- that are super-small compared to the size of the universe
- and we actually don't even know what the entire size
- of the universe is.
- But with that said,
- let's actually just try to appreciate how small we are.
- So this is me right over here.
- I am 5' 9", depending on whether I'm wearing shoes.
- (maybe five foot ten with shoes)
- But for the sake of this video let's just roughly approximate
- around six feet or around roughly,
- I'm not going to go into the details
- of the math, around 2 meters. Now If I were to lie down
- ten times in a row, you've get about the length of a
- 18 wheeler, it's about 60 feet long. So this is
- times ten. Now if you were to put an 18 wheeler;
- kind of if you were to
- make it tall as opposed to long, somehow to stand it up
- and you were to do that 10 times in a row, you'll get to the height of
- roughly a 60 story skyscrapper. So once again,
- if you took me and you piled me up a hundred times,
- you'll get about a 60 story skyscrapper. Now if you took that skyscrapper
- and you were to lie it down ten times in a row
