    BBC News - Black Hole's 'Big Meal' Could Spark Fireworks

    Link: BBC News - Black hole's 'big meal' could spark fireworks

    The black hole at the centre of The Milky Way might shortly swallow a giant gas cloud which is drifting close to the galactic centre.

    ...Impact is now just a few months away...
    However:

    ...But there is another possibility - the cloud could be hiding an old star. In which case, the big dinner date could be an anticlimax...

    About that ±1,000 years.

    If it happened at all:

    I hate the mechanics of it, especially on a friday afternoon.

    How do you get your head around the fact that our current fastest deep space vessel, Voyager, would take 450,000,000 years to get there.

    Reminds me of a young lad on Star Gazing last night, when the presenter told him that the star he was looking at might not be there because he's looking at it as it was 2.5k years ago you saw his head almost physically explode

    Space numbers are just inconceivably large. Once they get past something we can 'reference', like the distance between countries or the distance between planets in our solar system, we just can't imagine them.

    An example, Gliese 581 c, which is thought of as our nearest planet that could harbour life (that we've discovered so far), is 20 light years away. So, even if we could travel at the speed of light, we'd still take 20 years to get there!

    I have this with my daughter (10) at the moment .. my mum n dad bought her a telescope last Christmas but she's only just getting into it, so I'm waiting for a clear night to be able to sit out and have a look at a few, but I've been explaining about the whole fact that a lot of the stars we can see might no longer exist and we're just seeing them as they were.

    Mind you, that still makes my head want to explode .. I love it .. keep wanting to buy myself a half decent telescope, we live quite rurally, so light pollution is quite low around us ..

    After watching Star Gazing live I have a sudden interest in space.

    Getting my head around the fact that I am looking at something that happened ~1000's years ago is insane!

    I remember at one point they were talking about discoveries and how it will unlock secrets such as why time only goes one way and why the universe is made of matter and not anti-matter.

    WHAT THE HELL!

    Oh indeed, she's a little whovian (well, she's gutted Matt Smith's left - I think she just has a crush on him .. lol) so that would work well I guess ..

    Do you consider time to be a constant?
    What if on the other side of this black hole time flows the other way?

    Bloody mind boggling!

    I myself consider time a constant yes, it never stops. But to think that time could go back, what would happen at the point time started?
