    I hate being spoonfed the obvious, I must admit I didn't bother watching all of it as it was excruciatingly patronising for the first 20 minutes.

    I like this new theory. Every blackhole contains/leads to a new universe, and our universe is itself inside a blackhole.

    It's blackholes all the way down..

    Utter bollocks, a black hole isn't a hole, it's a ball of super-dense matter.

    Yeah, I can take that on board, like I said it was a bit pop. It did get better after the first quarter though.

    There was a thread somewhere a while back with a picture from Hubble with a small patch of space with no stars (apparently) that was magnified to show a further humungous galaxy of stars that was previously undiscovered.

    Wish I could find that thread somewhere, it was ace. Made me wince with the insignificance of pretty much everything.

    Yeah, that was a bit wanky of him I'd say Lexx.

    So what's Hawking radiation? A breeze coming through the hole?

    I just meant if it was all there with no-one for it...well. It would make no difference I know and I realise we all want to find an actual purpose to things (even though there isn't)...the whole thing just makes my brain melt.

    We haven't met any aliens because there's nothing that interesting on this planet worth travelling light years to see.

    Also we haven't intercepted any radio communications from other planets because chances are any other civilization would have better technology than that the odds of them having a similar technology level to us is mind bogglingly small.

    Chances are that star trek was right and until we discover faster than light travel no other galactic civilization will take an interest in us.

    But to our knowledge FLT is impossible.

    Well I agree with you, but I still find the alternative theories interesting.

    Yeah, sadly. Although we aren't all that far off it, theoretically at least. There are new theories based on bending space around the vehicle. Originally the thought was to use the elasticity of space to propel the vehicle, like riding the ripple on a pond.

    That's my point, however it should also be noted that physics doesn't like considering that FTL travel is possible because it mucks up all their nice equations they've written.

    But carrying on from that what work has been done on FTL travel keeps coming back with the need for more energy than the entire planet produces currently. So if you want to meet those aliens like rimmer does you better get researching better ways of producing vast quantities of energy.

    Lack of alien contact could be proof that FTL is not possible.

    It could also be said that given the vast size of space that actually randomly running into another populated planet is next to impossible.

    What I was trying to explain.

    If anyone fancies creating a gravity generator, we'll get right on it.

    Either argument undermines this Fermi paradox.

    I think I'll try re-reading that DB link again tomorrow - it's far too mind-boggling for 2am!

    I covered the basics in my post. It's only a theory though, and a very trekian one at that. There are many things that can travel faster than light, so while it's an effective theoretical barrier to ballpark, it's not set in stone.

    Look at it this way your travelling through a desert you have limited fuel so your going to want to see interesting things and you see a radio mast on the horizon are you going to have a look at it? Or are you going to keep looking for something more interesting?

    That's essentially what will be what every interstellar traveller will be thinking as they pass us.

    The idea that we're not important enough for aliens to come here is ludicrous imo. Some of you have been playing too much Mass Effect.

    The odds of aliens finding us are astronomically small as it is. Them actually coming here would be even less.

    My mum sometimes talks about something in the 90s on the radio. Some 'craft' had been sighted by many people who were all calling in about it. The station said they would update within the next hour.

    There were no more updates and nothing was ever mentioned or anything heard about it again anywhere.

    Not trying to say anything just remember her telling me one time,
