  • Hey, Vsauce Michael here, and I am back in New York City.

  • And today, we're going to talk about

  • loneliness.

  • But first, I just learned this yesterday, Bear Grylls, the host of Man vs. Wild

  • has three sons, and I'm not kidding, their names are

  • Jesse, Huckleberry, and Marmaduke.

  • Well, here's another name for you.

  • Michael Collins.

  • Not the Irish Revolutionary leader, but Michael Collins, the NASA astronaut.

  • This guy was part of the Apollo 11 crew,

  • meaning that he was part of the team that went to, landed on the moon,

  • and became the first people to walk on the moon,

  • except you might know Michael Collins' name as well,

  • because he did not get to walk on the moon.

  • Neil Armstrong and Buzz Aldrin walked around,

  • but Michael Collins had to stay orbiting

  • the moon in the command module to link up with them later.

  • Well, this is where things get lonely.

  • People realize that Michael Collins, there in the command module,

  • orbiting the moon alone was in a quite unique position.

  • When he circled around to the far side of the moon,

  • the side that faced away from Earth,

  • he lost all radio contact with Earth and with Armstrong and Aldrin.

  • For about the 48 minutes that Michael Collins was orbiting around the other end of the moon,

  • he was quite literally the most lonely

  • a human being has ever been.

  • He was the furthest from any other humans

  • than any human has ever been since the very beginning of mankind.

  • If you haven't yet seen Veritasium's video about how far away the moon is from Earth,

  • you should definitely check it out.

  • But the whole point is that we tend to think that the moon is much closer than it really is,

  • because most illustrations we see put the two objects quite close

  • because it's easier, but to scale,

  • this is how far away the moon is.

  • We actually measure the distance to the moon quite frequently using reflectors

  • that were left on the moon.

  • That's right, they're just sitting there all alone on the surface of the moon

  • waiting for us to shoot lasers at them.

  • By looking at how long it took the light to return to us,

  • we can calculate quite accurately how far away the moon is.

  • And we've been doing this for a while,

  • and one of the most bizarre things we've learned

  • is that the moon is actually spiraling away from Earth quite slowly.

  • Every year, the moon is about 38 millimeters

  • further away than it was the year before.

  • Thirty-eight millimeters is about one and a half inches.

  • Those reflectors are not the only thing we left on the moon.

  • We actually left a lot of man-made stuff, a lot of junk there.

  • There is an entire Wikipedia article just listing

  • the big stuff we left behind.

  • But there are man made objects that are even further away from the Earth than the moon.

  • In fact, there are four things that humans have built

  • that have traveled so far away from Earth, they are no longer within our solar system.

  • Voyager I is actually the furthest man made object from Earth ever.

  • And aboard, NASA included a gold plated record

  • that contained information about humanity,

  • just in case anything out there found them.

  • You can read all about everything that NASA put on the disc

  • by following a link in this video's description.

  • But the item that has always resonated with me

  • is a song they chose.

  • They put lots and lots of audio on the disc,

  • but one song in particular was chosen

  • to represent to whoever or whatever found it, the human emotion of loneliness.

  • The song is by blind Willie Johnson, and it's called Dark Was the Night, Cold Was the Ground.

  • There are no lyrics, just humming.

  • You can listen to it by following the link in this video's description.

  • And as you listen, think about

  • the weight of that meaning.

  • This song was picked to represent

  • to aliens what loneliness is.

  • Blind Willie Johnson himself wasn't blind his whole life,

  • he was blinded as a child when his step mother threw lye in his face,

  • and he died of malarial fever after his home burned down

  • and he had nowhere else to live but on wet newspaper.

  • But now, his song is way out there

  • in inner stellar space representing us.

  • Thanks for watching.

  • This point of light is Earth, as seen from 4 billions miles away by Voyager 1 in 1990
