The biggest threat to mankind. What will end the world as we know ?

Does the world need to be saved ? Are we heading toward an inevitable extinction ? will that be a new generation bomb ? or will it be pollution ? will it be depletion of natural resources ? or will the machines be our killers as it is suggested in many sci-fi stories ?

  • Jun 19 2012: I read an article talking about 10 ways the world could end in an instant. I forgot the name of the machine, but it is being used to recreate the big bang... but if it was unsuccessful it could cause a black hole and suck the hole world into it. I'm sure many of you know what I'm talking about. I told a friend about this and he told me that that it is not true and it has been put to use and has been successful and clearly we are all still alive. Can anyone confirm this?

      Jun 20 2012: I suppose you are talking about particle accelerator in CERN. Am I right ?

      Jun 20 2012: Yea CERN is working fine, also they theorise that they actually create black holes all the time in it but they're so small they destroy themselves, there was a statistic that they'd have to have X amount of power and a one in a billion billion billion chance of it creating a black hole that could grow.

        Jun 20 2012: it is not the right answer. the right answer is that cosmic radiation has particles many orders of magnitude higher in energy, yet we are here.

          Jun 20 2012: Krisztian I'm not sure if you're saying I haven't got the right answer here or not, but in case it is me, by power I meant they haven't got nearly enough energy to collide particles at such a speed so that they would then become a singularity. CERN doesn't deal with cosmic radiation

        Jun 20 2012: i'm just saying that if you tell people how low the chances are, it will not exactly satisfy them, as they can't relate to such numbers. however, if we point out that these energy levels might be a great achievement for mankind, it is a daily routine for the universe. it bombards us with way more energetic particles all the time. in this very moment. for billions of years. that is the perspective.
