Agreed, but that's true of everything not just time. Everything we know is based on observation and logical deduction - if we can't rely on that we might as well start making stories up about men in the sky with white beards

Replies: 9438 09 Dec 11 10:44 is it rue that no one really knows what goes on inside a black hole beacause the currently accepted laws of physics can no longer be applied... (and quite obviously nothing can get in there and sent data back to verify things)... if so perhaps each black hole is a gateway to a new universe...!!!!.. perhap the mechanics of the black hole are such that it can rip apart the fabric of space and time and at the black holes deepest recess a new universe in formed.... and that this what the "big bang" actually was......nothing but the stored energy of a black hole in some other universe causing our own universe to be born!!!! maybe this aint far off if tonights fascinating stuff on Horizon is anything to go by.... dont understand some of it but very interesting stuff. on iplayer later if anyone interested http://www.bbc.co.uk/iplayer/episode/b00nslc4/Horizon_20092010_Whos_Afraid_of_a_Big_Black_Hole |

..but then again...this still doesnt explain where the very first bigbang..singularity ..black hole or universe came from...
if you need a black hole to create a universe...but the black hole is formed in a universe..how did the very first black hole form!! baffling. |

hold up there egner - 500 years ago they didn't even know where thunder, lightening and aurora came from!
They're flying at and beyond the speed of light now! |

yes ivor....
imagine alll the stuff that will come apparent in the next 500 years....as long as we dont implode as a soceity.... perhaps the true origins of the universe will be found and it will be just as accepted as the fact the earth orbits the sun!! |

does it ?

black holes emit radiation don't they? So stuff can escape them.
p.s. there will always be a "then what created..." loop. |

can someone sum up Steven Hawkings theory on the Black hole in a paragraph. Ta

Everything that goes in to a black hole gets condensed to a singularity, a bit like the brain capacity of a Big Brother viewer. Images of things that 'go in' are left for eternity outside, as light can't get in, or out.

I don't think it's by any means 'certain' that life exists elsewhere other than earth in our universe. It's a possibility of course, but it's also possible that we're all alone. It depends on the probability of all the factors that make life happen coming together.
The odds could be higher than the number of atoms in the universe, never mind the number of planets, in which case we would almost certainly be alone in the universe. I tend to agree with this. I could obviously be wrong but I think we are nothing more than a cosmic accident. |

Horizon...What happened before the big bang???
http://www.bbc.co.uk/iplayer/episode/b00vdkmj/Horizon_20102011_What_Happened_Before_the_Big_Bang/ ..been on before...interesting though..... ..assuming there was a "big bang" of course. |
|
By:
the only certainty is that people and even scientists seem to equate the size of the universe
with the possibility of life. There is no correlation, the size of the universe plays no part in whether there is life or not. It just means that we can`t see far enough to prove that their isn`t. |

Excuse my ignorance guys but as a casual viewer of astronomical documentaries, I could've swore I've said 'fcukoff' at my TV when I've been told that black holes can be as small as a pinhead...I was probably pissed though
 I was under the impression that even super-massive black holes were relatively small (in size) despite that description as it's all about mass  I reckon a few on this thread have been scared to ask but I don't give a shít  |

"Black holes do have a finite lifetime due to the emission of Hawking radiation. However for most known astrophysical black holes the time it would take to completely evaporate and disappear is far longer than the current age of the universe. For example, a black hole with the mass of the Sun would take 2\times10^{67} years to evaporate whereas the age of the universe is only 13.8 \times 10^9 years (thus it will take more than 10^{57} times the current age of the universe for that black hole to evaporate!). "

and..."Black Hole Evaporation Time
Since the time is proportional to the mass cubed, a black hole with 10 times more mass will take 1000 times longer to evaporate and a black hole with 10 times less mass will evaporate in 1/1000th the time. If you get a black hole with a small enough mass, it will evaporate in a short time. For example, a black hole with a mass of 2.2 \times 10^5 kg will evaporate in about 1 second! This is approximately the mass of a blue whale - but the diameter of the "blue whale" black hole would only be 6\times10^{-22} meters which is about 1 millionth of the diameter of a proton! In contrast, a Solar mass black hole has a diameter of 6000 meters (or 3.7 miles) and an Earth mass black hole has a diameter of 1.7 cm (or 0.7 inches)." |

i believe that when two black holes get to close together one swallows the other,so if the betfair blackhole and the call me a taxi blackhole get to close to each other it may not be too promising.

...British astronomers have found 5 new super massive black holes previously obscured by dust and gases.....
...does every black hole lead to another universe????????????? ..perhaps!!!!...yep ...maybe the "big bang" was nothing more than all the energy flowing from a black hole.....through a rip in an adjacent universe caused by a black hole in that universe... |

I watched the numpty on Sky news trying to explain about this story. He was completely out of his depth and knew nothing about the subject. He was talking in miles and kilometers didn't have a clue about size or distance. When the co presenter asked him a question he couldn't answer it so he just repeated the blurb he was already going over. Totally clueless.
