"I think my fanny could take a compressed mercury... I quite fancied Freddie in his day   "

"...and for The Sun to become a Black Hole it would have to be compressed to a size of 3 kilometers!
What a mind fuck! "
How big a Black Hole would we need to get rid of the whole of News Group Newspapers Ltd?
I think we should be told. |

"The Earth cannot become a black hole, only stars can (I think). "
You're quite right, the Earth doesn't have enough mass, neither does our Sun come to that, the figures were for demonstrative purposes only. Our Sun would need to be three times it's size to have enough mass to compress down to a Black Hole. |

"the universe came from nothing and will go back to nothing and again again and again  "
You're saying that the entire Universe and everything in it must have all been contained within a single point in time before exploding so violently that it is still expanding now, some 9 billion years later, and to believe that is to believe that at another point in time it must start contracting again, which means that if we take today as the Universe's Event Horizon then the Universe in this lifespan has at the very least another 9 billion years before it vanishes into nothing again.
I don't buy that.
I think the answer is much more simple - I think it's always been here, it always will be here, and that it is infinite in size as well as in time. |

Why 9 billion? Aren't they finding light that's now 13 billion years old?
That is some tape measure. |

As stars burn up their fuel reserves they collapse under their own gravity & generally, dependant upon their size/mass form either blackholes (the larger stars) or neutron stars (the smaller ones). Both are essentially super-condensed star cores, of the two, our own sun is far more likely to become a neutron star. Our sun will, in time, eventually run out of fuel, swell massively (destroying all life on earth- then the planet itself) & collapse down to a condensed metallic core. Imagine a solid rock the size of Hampden stadium being super-condensed down to the size of a grain of sand (like a mini neutron star)... it would still weigh 4 million tonnes!
