who woke up to this randomly on n jus decided to leave it on n start watching it😭
Thanks this documentary helped me fight insomnia !
I have no idea how people use these videos to fall asleep to. This type of information is what I use to keep myself awake! Nothing interesting on TV to watch? Bored out of my mind? Still too early to go to bed? This will keep me up and awake well past the time I should have gone to bed! Seriously, how does one fall asleep to it?
Goodnight yall 🌖
Poor Pluto. That was brutal.
Pluto will always be a planet to me
Dude REALLY had it out for Pluto...you'd think it stole his wife and dog lol
Never forget! PLUTO 1930-2006
Pluto is still a planet
I just love these types of videos! Expect a ad every 5 minutes!!
This was posted 3 weeks ago from NOV 2023. It speaks of New Horizon going to Pluto. This video is about 8 years old. I like how the Pluto expert sitting in the Rocky Mountains talks so sure about what Pluto's surface is, and now we know he was totally wrong. Pluto is not pock marked with craters.
I couldn’t care less what that dude says about demoting Pluto, Pluto will always remain the 9th planet in my opinion
"Pluto had it comin" 😆
These shows are quite interesting & thought provoking, its disappointing to know that in my lifetime I am not likely to find the answers to all my greatest questions. For example, are we alone in this universe, did Yoko really break up the Beatles, who killed JFK, is TuPac still alive & a million others. Burning questions; I think would I rather have Jeff Bezos' money, all 500 Ka-jillion dollars or the answers to all my questions? 500 Ka-jillion is a lot of money but knowledge is far more valuable. I really want to know where TuPac is.
"Pluto had it coming" wild statement
"pluto had it coming" My goodness lmao
Falling asleep to a video means it is entertaining, well made. Most importantly the commentator voice is what attracts. Love it!
I remember watching these kind of videos on the science channel when I was young.
The basic measure for a planet should be that it has enough gravity to hold an atmosphere, and it shouldn't matter what if anything it's orbiting.
I don't care what people say pluto is a planet
