Everything and Nothing
Two-part documentary which deals with two of the deepest questions there are - what is everything, and what is nothing?
In two epic, surreal and mind-expanding films, Professor Jim Al-Khalili searches for an answer to these questions as he explores the true size and shape of the universe and delves into the amazing science behind apparent nothingness.
The first part, Everything, sees Professor Al-Khalili set out to discover what the universe might actually look like. The journey takes him from the distant past to the boundaries of the known universe.
Along the way he charts the remarkable stories of the men and women who discovered the truth about the cosmos and investigates how our understanding of space has been shaped by both mathematics and astronomy.
nothing is not an empty box. an empty box IS something.
empty space IS something.
Nothing is the absense of even this box, or space,it is then, nothing.
not even a place for something to be.
they always put something there and CALL it nothing to start this fallacy.
it is only real when you remove even the BOX.
That is nothing.
If the most distant galaxies that are close to the edge of our visible universe have the greatest red shift I can understand that and it just seems intuitive that the light we are now seeing from those galaxies are from a more infant universe but to claim the universe is expanding at a faster rate as a result of those greater red shifts fails to make sense to me.
So the galaxies we see that are half that distance of our visible universe have less red shift and are from a more recent past and the galaxies that are a fourth of that distance of our visible universe have even less red shift and are from an even more recent past. Am I missing something? Seems to me the universe is slowing its rate of expansion. We know the Milky Way and Andromeda are on a collision course and will merge together in the galactic near future.
Since space can expand faster than the speed of light I’ll speculate that it can contract faster than the speed of light also. What if... beyond our visible universe or even within it for that matter, the universe is collapsing in on itself faster than the speed of light. We would never know. In less than a flash the universe as we know it would cease to exist.
Really good doc. I liked how it explore the subject through the evolution in our knowlegde of it.
This doc is so goood.
Please do not make generalized statements like if a star is not very bright it is likely further away. All stars do not have the same intensity. All stars are also not the same size.
WOW! Many thanks to Dr. Al-Kahlili for this engrossing documentary and for presenting it in such a beautifully understandable way. And, thanks to the BBC for producing it and to Michael Shermer for pointing it out on Twitter.
Amazing. So much complexity and beauty! Did all of it happen by accident? Did all of this order, which grows more mind-boggling the more we learn about it, arise out of chaos?
It was an attempt to prove something that he didn't understand the microwave pictures of the universe shows a cosmic egg shape that is flat . No explanation of that fact and the end of the universe could be a big freeze.
I watched this over a year ago but i want to watch it again. One of the docs that got me into this site. Great watch.
I would love to watch it but I live in the USA and I cannot find a link that works here. Can anyone help direct me to one? Thanks.
A must watch for anyone with the slightest interest in the Origin of the Universe. Very well explained.
i have this double episode show and i think its marvalous
wait where is the full thing?!
This is an amazing piece of work, exploring space, both inner and outer. The Universe is a tantalizing and beautiful place.
Thank goodness for the BBC. Imagine if there was an American equivalent which was devoted to making doc's like this. Imagine how many more we would have! Aw well, at least we have one rational network in the english speaking world.
Watch out Michio Kaku, you've got some competition in Jim Al-Khalili.
Big thumbs up to the production crew on this one too. Beautiful cinematography and special effects.
Incredible doc. Very entertaining, informative, and thought provoking. I agree with Earthwinger about having actual professionals in whatever field is being documented hosting a documentary instead of paying actors. Professor Jim Al-Khalili did an excellent job of getting me more into the already interesting subject matter.
amazing, mind blowing, especially part 2 about nothing and the quantum world
the sun will be off very soon
"although this sounds completly rediclous, let me assure you that its true"
Pre-nothing and post everything: This leaves the question: What is before nothing? What preceded the collision of matter/anti-matter? What other dimensional collision caused this? Is there a relationship between the string theory and this matter/anti-matter reaction? On the other end of the spectrum of everything? What is beyond the cosmic web? Is it an ever conceived fractle with larger and larger scale from the observer's point of view, which breaks into yet another dimension?
See above
Ya gotta love Professor Jim!
One of the things that I love so much about BBC science documentaries, is that rather than draft in actors that give good face, or use husky voice-overs, they instead prefer to use scientists whose passion for their subject is infectious. And this one is an absolute "must see".
I've actually watched it a few times now, as I find it so engaging. I must confess though, I can't help but chuckle to myself at the scene where Prof. Jim is joined by Dr Andrea Sella, who creates a vacuum using mercury. Maybe it's just me, but it seems sweetly homo-erotic, especially the bit where Sella speaks Italian to him...cute! :D
This by far is one of the best commentators today. Up there with Carl Sagan in my books (close second i mean). I like how this Prof narrates. And he does come across like he knows what he's talking about.
Thank you for this.
Frighteningly illuminating.
