jeez...this stuff fascinates me.......
10 billion times the size of the sun!!!!!!
http://news.bbc.co.uk/today/hi/today/newsid_9656000/9656921.stm
imposssible to imagine how big this must be.
plus Kepler telescope finding one potential life hosting planet orbiting its star in the "goldilocks" zone each day..
incredible.
imagine being alive in 50 or 100 years to see what has been discovered...
mind blowing.

Hold on ... ermm ... calm down, calm down their la - ten billion times the mass of the Sun. At least that's what it said on the website this morning, not 10 billion times bigger which is ... big.
I agree though about being alive 100 years from now, though we'd probably be saying the same thing. |

same thing ... then ...

not if you're a black hole it's not!

You'll probably find it's the size of a dustbin or something

You`ll actually find that the event horizon is bigger than our Solar System. Now that is a massive black hole in anybody`s language. The size of the Universe is mind boggling. Take the Milky Way galaxy for example, our home, if one could travel at the speed of light, 186,000 per second, it would take 100,000 Earth years to go from one end to other. Now that`s BIG. But bear in mind that the Milky Way is one of only hundreds of billions of similar galaxies and then try and comprehend the size of the Universe. Fascinating stuff Egner.

the event horizon is the actual circumference of the Black Hole, so it`s a little bit bigger than a dustbin lid.

By:
yes mac.....blows me away......
for me... life on other planets somewhere is a certainty......there are so many planets going round so many stars that it beggars belief...and mathematics...that there isnt a place that has been stable enough for long enough to develop intelligent life.....even if not exactly like our own.... cant prove it of course but this is my gut feeling. |

I agree entirely egner, biggest certainty since sliced bread!

Imagine if many, many planets are found with liquid water, the right climate and atmosphere etc, and absolutely no life is exists. Not even a single cell. And we try to understand it is not inevitable that life will exist just because all the elements are perfect. It will spin our science on its head as we begin to look for our almighty creator...heavy shitt!!

Take the Milky Way galaxy for example, our home, if one could travel at the speed of light, 186,000 per second, it would take 100,000 Earth years to go from one end to other
It would take no time at all, if that speed were possible. Close, but under c and you can make it any time you wish. Seeing as we are talking about hypothetical and impossible numbers: 99.99% the speed of light gives you 1414.32 years. 100,010 years would pass on Earth [ignoring accelerations]. the event horizon is the actual circumference of the Black Hole, so it`s a little bit bigger than a dustbin lid Aye. Towards the business end though it’ll be the size of a dustbin somewhere and at the business end it’ll be so small it has no size, which is thought provoking when you realise what has gone into it. At the very big or the very small, the universe is breathtaking. Imagine if many, many planets are found with liquid water, the right climate and atmosphere etc, and absolutely no life is exists. Not even a single cell. And we try to understand it is not inevitable that life will exist just because all the elements are perfect. It will spin our science on its head as we begin to look for our almighty creator...heavy shitt!! It’s possible that there’s nothing out there (I tend to agree it’s not likely) but if it is true, imagine - all that universe and there’s just us, watching Coronation Street and getting uptight about someone that’s parked in ‘our’ space. If the universe is that vast and there’s just us, it may be that the creator has lost us and that’s why we don’t hear from him - perhaps he forgot where he left us. He won’t be that impressed when he turns up and finds us in, in our dressing gowns, watching daytime TV on the sofa and farting occasionally. |

he shouldnt have dropped us down back of his sofa while lifting a cheek to fart then

According to string theorist's there could be 500 to the power of 10 universes.
Our universe is made up of approximately only 125 to the power of 10 atoms(not counting dark matter and dark energy) mind blowing |
|
By:
And we might be the only brains on this brane.
I wonder if we'll ever be able to say that string theory is anything more than a philosophy given the practical limitations of ever proving it? |

I agree entirely egner, biggest certainty since sliced bread! I assume that you have heard of Frank Drake`s equation, but if not check this out: http://www.youtube.com/watch?v=dilKJ6uLCc8 Drakes equation has been debated and the consensus is that it's not very good really. The numbers picked are too arbitrary and not enough factors are considered. I think they might have designed a more advanced equation now. |

By:
Drakes equation might as well be
total guess * random number / wild speculation |

swap the multiplication and division symbols and I think that was his equation, brenda.

theres more stars up there than grains of sand on the earth - get yer head round that one ! Heard that sh1te when I was 12, how can they prove it and who has counted? |
|
By:
Astronomers love big numbers and, yes, it is fascinating and mind blowing stuff.
I like the one about grains of sand and I had people on here, and elsewhere, trying to guess how many buckets/egg cups full would equal the number of stars. Typical answers were 3/4 of a bucket plus 4 egg cups full. That sounds like plenty to most folks! The other big number, that is hard to comprehend, is that if it were possible for a passenger jet to fly none stop, it would take 1,100 years to fly, just one time, around the largest known star! And talking about astronomers liking big numbers, Patrick Moore once came out with the classic "500 thousand millionths of a......."! I've forgotten to what he was referring but I ask you, what's wrong with saying "half of"? |

By:
given how much space is in space, it must be less than 1.01 there is life out there of some sort.
we should hope that whatever they are, they don't visit earth. america will first try to east them, when that fails they will try to shag them, and finally after 2 failures, they will do what they do best, they will try to destroy them. and as they found us, they are obviously far more technically advanced than we are. So.....to shorten the obvious inter-galactic war, bend over and kiss your arse goodbye when they land. |

'eat' not 'east'

I get just over 5000 times the radius of Pluto's orbit for the size.
Of course, we could be inside a really big black hole already and not know it... |

Hold on ... ermm ... calm down, calm down their la - ten billion times the mass of the Sun. At least that's what it said on the website this morning, not 10 billion times bigger which is ... big. The radius is proportional to the mass, so that's 10bn times bigger than the equivalent hole that the mass of the sun would form. That's 3km, so the big hole is 30bn km in radius. If you now decide "big" is volume, then you're talking the cube of that... |

By:

That's a discussion in itself. Look at conflicts on earth, the furthest travellers usually have the better technology and win the day. But there are many examples where the technologically backward civilisation, with home advantage, springs a surprise. A bit like Newcastle beating Gloucester in last weeks Aviva premiership. Or perhaps the first serious attempts on the South Pole and back which ended as follows using chess notation: South Pole 1/2:1/2 Scott South Pole 0:1 Amundsen South Pole 1:0 Scott The conquistadors versus the Americas was a massive and easy win for the travellers of course and examples like that are in the majority, but it's not always one-sided. I'd go 1.3 we have to kiss our arses goodbye in the twomatchpoints scenario. |

08 Dec 11 00:54 the event horizon is the actual circumference of the Black Hole, so it`s a little bit bigger than a dustbin lid Aye. Towards the business end though it’ll be the size of a dustbin somewhere and at the business end it’ll be so small it has no size, which is thought provoking when you realise what has gone into it. The event Horizon is it's gravitational pull from which light can't escape isn't it? I would imagine the Event Horizon of a Black Hole with 10 Billion times the mass of the Sun to exert a pull of at least a few billion miles - maybe a lot more |

By:
,A pull sufficient, that is, to not let light (or anything else) escape
