## incredible programme about infinity

http://www.bbc.co.uk/iplayer/episode/b00qszch/Horizon_20092010_To_Infinity_and_Beyond/

Amazing. Truly spell binding. Simply incredible.

Amazing. Truly spell binding. Simply incredible.

## Annoyed I missed this and I never get round to watching stuff on the iplaya.

## I liked the bloke who denied infinity.

And said when you reach the biggest number and add one, it goes back to zero. Also liked the fact it ended on Monkey Gone To Heaven. Made my day, it did.

## the bit that expl;ained the odds of the monkeys typing the shakespeare was amazing

the same person winning the lottery every time for 29 thousand years :D

## 'It was the best of times, it was the BLURST of times??!!'

## also Jonsi & Alex's 'Boy 1904'

while talking about Graham's number!

## These Horizon shows of late

are genuinely inspired. I will have to watch this now, on lunch, and reveal myself as a massive geek to my co-workers. The show about black holes led me to apply for a Physics course with the Open University.

## HORIZON FUCKING KICKS, BITCHES

This was good, but not as good as the quantum gravity ones with that indie guy who's actually a 40 year old professor.

Infinity though, does it exist Seriously? Makes sense that it doesn't. What if the universe is one massive donut shape? Then again what's outside THAT?

Probably Jeremy Kyle or something telling God he makes him sick.

## brian cox

I had an insatiable love for him once.

## Not that Brian Cox, obviously

## Brian Cox, ex D:Ream is it.. looking forward to his new series on

the beeb when it comes on.

## Prof Brian Cox

honestlty

## Sorry, figured it went without saying that it wasn't the actor.

## Would all this talk of him be eligible for the indie thread?

## it takes THIRTY YEARS to count to a billion

I love this kind of thing. See also the Alan Davies maths programme (it's on YouTube)

## Is it about the never ending story?

That film made infinity hip.

## Ner ner ne ner ner...........I found it a bit meh!

they kept talking about it as if it were a number rather than a concept, which is the big problem they have in understanding it, also all that bllx about 'hey we've found an even bigger number' whoooopdedoo....really? in what base exactly? why do people automatically think in terms of base 10? ok yer average joe maybe.....but theoretical mathmaticians?

Fair enough about Graham....in that he actually had a purpose for postulating his 'very big number' that is of relevance, but as for just talking about one hundred zeroes and stuff.....thats just emotive sentimental bllx.....

hah..... call the last single diget of base Fth to the Fth (base 16) the tilda sign......then calculate ~ to the ~th to the ~th........see its easy to just make up big numbers.

PS I am curently testing a data migration that is large, but obviously quite small if you reflect on it in bigger terms.......its in Petabytes.

Mine is bigger than yours...etc etc

## sorry

## well it is a concept

because, by definition, it's NOT really a number... you know? i liked the context it was putting it in. and the odds and stuff.

"it's easy to make up big numbers" is pretty much their point though, isn't it?

## The point of the programme didn't seem to me to be about 'massive numbers'...

...more about the implications of it all. It's just that it was probably necessary to discuss BIG NUMBERS when talking about infinity, I guess.

## not necessarily....you could contemplate smallness

and not just in terms of numbers, for instance rather than going big you can go really small and start to consider whether or not space is infinatisimally divisible or wonder whether space is comprised of considerable small 'units'......this is interesting because then you will be considering fundementals as to energy/matter and dimensions...or space......for instance is any small measurement of space possible unless there is matter or energy existing nearby (mater would create a gravity field in which case space would have 'features', but if there were not matter or energy then would featureless space actually have any dimension........the concepts of small infinity (smaller scale) are actually a good idea to muse upon if you are having problems with big infinity (bigger scale and linear progression)

I'm not sure what its called when the postulation that if you go in one direction in the universe for long enough that you would then end up arriving at your starting point from the opposite direction......or indeed that the equivalent postualtion that if you go inwardly in decreasing scale so far that you end up coming to your starting point from the opposit direction (i.e. big)

but its something worth considering......is the universe just infinate with regard to linear distance or also infinate in scaling down? also surely if the linear distance is expanding then surely the scale could be increasing.

If you were to 'go to the edge of the universe' and then go further then you would not go beyond the universe, because as you have gone there, the universe has just expanded......cos you are part of the universe.......that wasnt mentioned in the horizon program, which was dissappointing......i would like to hear theories along those lines with regard to scaling down too.....i.e. if you could measure smaller than anything before, then the universe has just expanded in downward scale?

I think that horizon should have done a whole series on infinity.....that program could be the starter program.

## I'm not sure I understand that last point, if the universe just scaled down, then you would'nt be measuring smaller than you had before (at least there would be no way to be aware of it)

Anyway, it wouldn't matter how many programs you dedicated to infinity, you'd never be able to fit it all in.

## This set me thinking about the universe,

and how there's no direction, really. Up is down, left is right, but most disturbingly of all...from space, the Australians could be seen as being above us. *Shudders*

## I watched a QI episode (gravity) and something in that tickled me

apparently someone made an earth sandwich... i.e. at the same time on points exactly opposite on the earth people put two pieces of bread on the ground :D I can remember exactly where it was Spain and somewhere else I think, anyway that amused me

## need one of these.....

Madrid is near Auckland

## Thanks

If you find Atoll Tematagi then there is a place on this where being a muslim will be easier, because you can face in any direction to prey towards Mecca (kudos to QI for this)
