Brian Cox visits the world's biggest vacuum | Human Universe - BBC

In this episode, Professor Brian Cox explores our origins, place and destiny in the universe. We all start our lives thinking that we are at the centre of the universe, surrounded by our family and the world as it spins around us. But the urge to explore is strong. Brian tells the story of how our innate human curiosity has led us from feeling that we are at the centre of everything, to our modern understanding of our true place in space and time - that we are living 13.8 billion years from the beginning of the universe, on a mere speck of rock in a possibly infinite expanse of space.

I love the fact that they know exactly what's gonna happen but still find it marvelous when it happens.

[rick]

Imagine Galileo seeing it he would have cried watching this amount of beauty.

[baekhyuneeu]

Everyone's saying their teacher forced them to watch this but I came here myself....

[JavierBonillaC]

Not having this in real speed is the most frustrating thing that has happened to me in like 5 years!!! Imagine the chance of seeing a feather fall like a rock! Instead we get slow motion and the feather falling like we always see it falling.

[adam_fakes]

I love the look on the Engineer's faces, they know it, but to see it.

[Desmodromic]

In Nasa research center, they countdown from 10 before flushing the toilet

[TackerTacker]

Why did they show it in slowmo only? I'd have loved to also see it in real time :(
Seeing a feather drop to the ground as fast as a bowling ball would've been the much more interesting shot IMO

[pandorahecate]

Absolutely fascinating. Makes me wanna become a scientist. You can see how enthusiastic they are about it all makes me smile and its one of the most beautiful videos I have ever seen

[michaelmannucci]

I'm actually so frustrated that they didn't show this in normal speed. I want to see feathers fall at regular speed. Wtf is wrong with the producers?

[adamhowitt]

I’m sorry but what every person wants to see is a sheet of A4 paper go down perfectly straight and not do flips

[TonyBullard]

I can't believe they never showed it fall at full speed! We've all seen bowling balls and other heavy object moves in slow motion...that's not unusual at all. But to see a feather fall quickly from that height without it being disturbed by air around it, that's novel! And yet the editors chose to leave out that footage entirely. I feel robbed!

[burningnose]

I am 62 and no teacher said I should look those videos. They are interresting for me...

[jurassicparkmark]

Who else is watching this in 2020 because your teacher made you

[mazeu]

I wanted to se how weird it would look if the feathers was falling fast, as fast as the bowling ball. But of course this was in slow motion.

[WildPhotoShooter]

Thinking of how Newton and Galileo would react to this, seeing their lifes work in action, puts a lump in my throat, they were two astounding human beings.

[rajdeepchakraborty]

This is one of the most beautiful video I have ever seen. Years and years of humans pushing their knowledge just to understand the working of the universe in a much better way.

[zeet]

It's amazing how a crazy scientist named Galileo gave this theory 400 years ago.

[patroclus]

It's the most beautiful thing to watch, ball and the feather falling together.

[dsdy]

I think what I love most of all is how all the seasoned NASA engineers are still nerding out about it. They put men on the Moon, the concepts involved in this experiment are child's play for them. But seeing a bowling ball and a feather fall at the same time, seeing that visceral smack of the feathers and watching the equations you use everyday come to life is still special.

[Razta_S]

These guys who have been managing this multi million dollar structure are still fascinated by how this known principle of gravity works. That’s what I love about scientists. They are genuinely amazed by their field every time.
