Wonders of the Universe

Entropy always increases? how did the sun, planets and life happen then, it required an decrease in Entropy... I think he over simplified the rule? or am i missing something....

Entropy usually inceases unless influenced by an external force especially if the external force is inteligent?

The assumption is that the universe is a closed system therefore decreased entropy in one area requires an increase somewhere else, and as work can't be produced perfectly you'll end up in a state of maximum entropy (eventually).
 
I know why the predictions were made. I was saying that he wrongly implied a certainty to those predictions. Nothing in science is certain - certainly not things that far in the future.

Totally agree if space is infinate there is no end, however if there theory was correct after X ammount of years the universe dies what happens then, he was implying that protons seperate amongst the vast nothingness of space. mmmm so would the protons and atoms react again?

ta, that clears that up, I was jsut contemplating how you would fire up a star once it had died and comming to the conclusing you will eventually run out of matter to convert to energy to power what ever you were doing...

So if i make the castle I caused slight move to higher entropy when the energy I used etc is taken into account..
 
Well i think it was not as good as wonders of the solar system but was still the best thing on t.v. last night. Maybe it has something to do with entropy or the arrow of time. :D
 
Watched this yesterday but first half or so was not as exiting as the wonders of the solar system, but it picked up later on. Both me and my wife started watching this as we liked the solar system series but soon found out she was asleep! Imagine my agony when she woke up and asked me "So what happened?"
I just said "Its too complicated!"
 
Why? It was most definitely awful. Gutted too as I like Brian Cox and his last series was great.

lol. if you honestly thought this was a good program i would really look at how you were educated.
A program that is filmed essentially with him looking at an object or jetting round the world whilst awkwardly explaining relatively simple theories is not good tv.

Please don't make false assumptions on my education. Its like me saying because you don't use capital letters, you went to a crap primary and secondary school and fail at life.

As someone said, it is entirely subjective. Awful TV for me is Big Brother and EastEnders. This was high quality, high budget television. It might not go into enough detail for you, but to right it off as bad in my opinion is very close minded. It obviously wasn't intended for the people holding physics degrees among us (not me), it was intended for the slightly above average citizen.

I think you're missing my point! :p In the program Brian Cox stated with a high degree of certainty how our universe would evolve. This was based on current physical models and laws (general relativity and 2nd law of td in particular) - my point is that these laws and models are likely to be superseded so making concrete statements about the long term evolution of the universe is not advisable. He fell into the classic trap of the over-eager scientist.

Science is humble.
 
Last time I watched this guy he was harping on about GCSE Science level stuff, and was hailed as revolutionary because apparently nobody has watched a documentary on Astronomy before.

Is this any different?

I thought the content was brilliant and was more in depth than the Solar System series.

People with Astronomy degrees should keep schtum, as this is obviously not meant for you. I'd never heard of Entropy before, so i'm sure myself and many others learned something from the show.

It's TV programmes like these that open peoples minds to the actual vastness of the Universe and how inconceivable it is to think that we are the only planet that supports life.

IMO, these programmes play a part in helping to ease the blind faith some people have towards religion and they may start to question their beginnings. I cannot say for sure there is no God, but people who blindly follow religion and don't allow themselves to question it are very small minded.

10 minutes in and hardly any meat to it, not a good way to start a documentary. The endless spinning/panning camera shots and really...reallly...drawn out sentences makes it look and sound like it's some sort of drug trip tbh. I agree there was a lot of waffle.

Through the Wormhole with Morgan Freeman or better still, 'The Universe' are so much better. They strike a nice balance between being entertaining, easy to digest and interesting at the same time.

Less of the trippyness and filler landscape/environment shots and it would be much better. Entertaining and to the point please bbc!.

Stay with it, it gets much better.

Easy - "Everything dies at the end!"


I found it interesting, but the visuals and presentation felt bloated and OTT at times. Going over the same topic over and over seemingly nailing it home with a trip to some unecessarily remote location as well! And how many times do we have to see his arse walking away in slomo?

Picked up towards the end, and looking forward to more :)
 
The timescale for what will be the "death" of the universe is based on proton decay or rather than time for them all to eventually decay... proton decay is predicted by a lot of the GUTs.

Whilst not a cast iron cert for the future of the universe, it probably is the most likely end result based on all of the information we have. "The big crunch" which was/is a possibility depending on the total mass of the universe has fallen out of favour because of all of the data we have now.

Whilst not perfect, it's not a bad programme by any means, definitely the kind of stuff the BBC should be making. :)
 
Wonders.... will never cease, as they say.

1) I guess Cox had always wanted to go and see those turtles on that beach and that was one way of doing it.

2) Impressive visuals unrelated to the subject matter? But they need something to get people to buy the Bluray. Public service broadcasting at its best! (worst!)

3) Was Carl Sagan's 'Cosmos' so dull and plodding as this was?

Besides Cosmos, I'm vaguely reminded of a series called 'Space' (Hyperspace in America) on the BBC, narrated by Saml Neill, i remember it being pretty decent.
 
I enjoyed watching Brian Cox on his hols :)

So, the universe is like a crap fireworks display then?

Starts with big loud rocket, followed by a pretty starbust which don't last long. Then your stood there for the rest of the night watching a black cloudy sky, freezing your a** off :D

Cosmos is dated, but still fabulous!

There's talk about a new series. If it's only half as good as the original, it will be an absolute treat!
