    I just want to live long enough to see people land on Mars, thats all I ask. You have a little under 30 years to pull that one off (given the average age in my family), GET TO IT!

    You think they haven't ALREADY found the secret?

    You really think we went from walking in front of a train with a red flag so as not to scare the horses, to manipulating atomic sized particles in 200 years ON OUR OWN?
    The last 30 years in particular are incredibly fast for natural progress.

    What happened between 1000AD and 1600AD? We found gunpowder.
    1600 and 1800? Some metals
    1800 and 1900? Industrial revolution, some electrical stuff (lighting and magnetic things)
    1900 and 1950? Flight and microbiology radio radar Atom bomb.
    1950 and 1990? leaps in all major sciences space flight with chemical rockets, nuclear power.
    1990-2000? Computer and telecommunications takes off.
    2000 and now Increases in technology over the last ten years exceed everything that man learned in the last 2 million years.
    Solar cells can now be painted onto surfaces (but they aren't going to release that too fast are they? Not til they run out of oil anyway.)
    2 terrabyte hard drives are cheaper now than 40 megabytes was in 1995

    Ram is measured in gigabytes - fifteen years after it was measured in kilobytes.
    Cars with 2 litre engines return 50 miles to the gallon and 150 horsepower.

    Planes can carry huge cargos - and we can't get off the surface of the planet??? SURE WE CAN'T?

    The issues I am thinking of, are not so much in the "Propulsion" end of the topic (Although, it's still an issue, obviously).

    I think the problems are going to be with what a "human" can actually tolerate & endure....Meaning, physical & mental limits.

    1) Loss of bone density

    2) Loss of muscle mass

    3) 5-10 people stuck inside a cigar tube for 9 months, would probably kill each other.

    4) No other human interaction, no families, no loved-ones to be with, no friends...etc...Emotionally, there's a lot to deal with.

    I'm sure some problems could be dealt with, and artificial gravity can be created, and MAYBE some sort of "Suspended Animation"????? Who knows.....but, I just see "PROBLEM" written all over space travel, unless all kinds of issues can be dealt with.

    Just my 2C

    All your concerns boil down, really, to this one. Time in space. You suggest 9 months.

    There are already several examples of people living in space for longer than this arbitrary limit.

    Polyakov, Avdeyev, Titov, Manarov, Romanenko, and Krikalev all stayed on Mir longer than 270 days.

    There's more than a dozen who've surpassed 100 days.

    The 9 month limit is, as said, a bit arbitrary however. If we presume current propulsion technology, then we're talking about trips that last dozens of generations, not years or months.

    If, on the other hand, we presume the breakthrough IS in propulsion, then ideas such as warping make interstellar trips functions of hours or days, not months...so the concerns above are moot.

    I'm sure some problems could be dealt with, and artificial gravity can be created, and MAYBE some sort of "Suspended Animation"?????
    Another valid postulate. Presuming, of course, the computer in charge doesn't kill them all.

    (Still, arguably, the scariest 120 seconds in film history, imo)

    even if we could transport ourselves to places in the form of light, it would still take a long time to get from place to place in this galaxy, let alone the universe.

    Remember, those Cosmonauts that survived more than 100 days in space were inside the magnetosphere of the earth and thereby protected from most of the deadly radiation that comes from the sun and other sources. I really wonder if we are even close to being able to shield humans from cell damaging radiation. I know about water jackets and I also know that to launch enough water into space to provide even a moderate shield would take a lot of very expensive launches just for one mission.

    I agree with all comments on the myriad of negative effects on the human condition in space...mental and physical.
    Per my previous inference, even the speed of light isn't fast enough but if we could create gravity during space travel and warping space or some other method is 'stumbled' upon it could noticeably minimize those 'negative effects' because length of time during space travel is greatly reduced as already eluded to by Eor312.

    It's still lofty thinking we could surmount these obstacles any time soon.

    That's my take on it......carry on.

    Agreed.

    But then again, when's the last time anyone got anywhere new and exciting by thinking slow and conservatively?

    I think I will just sitback and look at the stars and see what the world and all of the pepole will bring to it and were it will take us.

    Remember 1960?
    The transistor Radio had been invented. Computers in UK amounted to one in London and one in Glasgow University (I'm not sure this is correct but it's close) They had the power of a pocket calculator (Not a Texas Instrument one)
    A modern calculator has more power than the TRS 80 they used for Apollo.
    My ipod has more storage than Apollo's computers by a factor of ONE MILLION.
    Of course we can't go to the stars this week - next week????? Well maybe

    Other interesting facts about 1960.
    Music was recorded by stamping a vinyl disk with a wiggly line and reading it by scratching a stylus in the wiggly line
    Cars had a fuel efficiency of 15% that is 15% of the fuel was used at the road wheels.
    Lights were produced by heating up a piece of tungsten in an inert gas until it gave off light.
    Petrol was 3/6 pence a gallon. (I believe it still is in USA)
    There was only 4 pieces of junk in the sky.
    It was possible to buy an individual photoelectric diode. Now my camera sensor has 12.2 million of them in the space of a large postage stamp.
    Bar codes hadn't been invented. Nor had electronic fuel injectors, mobile phones, colour TV, LED watches, Radial tyres.
    The smallest TV camera could fit into a large suitcase.
    The mile took longer than 4 minutes to run. (Now you can't even get on the Olypics team if you can't do a sub 4 minute mile).
    Sean Connery had hair. You could smoke anywhere.

    Ah - times were different. Were they better though?
