    Not really true CB.

    If they were cycling and headed east (sun rise) as the sun continued to rise they would have to adjust their direction to the right as time passes. If the area was large enough and with no obstructions and they cycled at a precise speed the shape that would be travelled is a gradual curve outwards from left to right and at midday it would return back towards where you started from.

    I have googled this and the best reply is copied below:

    At 6AM precisely, the sun rises. The walker sets his watch for 6AM on the dot and starts jogging at 8.0 miles per hour toward the sun.
    At 11:59:20 AM on his clock, the sun is precisely overhead. He's arrived at his turning point before noon because he was walking with the rotation of the earth, into the sunrise. He has now traveled 47.912 miles due East.
    He turns around and heads back. At 6:00:40 on his clock, the sun dips below the horizon. He stops. He has now traveled 48.088 miles West from the point where he turned around, or (48.088 - 47.912) miles past his starting point. That's about 300 yards, or 80 seconds of walking from his original starting point. He's gained 80 seconds on the sun in this brisk 12 hour and 80 second marathon.
    If you agree that his morning trip is shorter than his evening trip, as it must be, then the conclusion is inevitable. He walks back in the afternoon further than he walked out in the morning. "Time" cannot cancel out, there is no negative time.
    Unless the walker is a positron or something.

    What direction would you travel once the sun became directly overhead. Secondly would my cherry magnum have melted?

    Mmm....I suppose at midday the ride would stop or you just carry on in the same direction....if you did stop you could eat/barf the cherry mag

    Of course if Google says it, it must be true!

    We are talking about the difference between perfection and a practical situation here. Just think about it logically. Lets just assume for a moment that the sun is passing much faster across the sky at a speed you could actually see it move. You would never set off in its direction because in the time it took you to take your first step or pedal turn it would have already moved so you'd have to realign the angle of your position, however small that is, and so on for every nanosecond until it set. All you'd do is change your angle of orientation so you were looking directly at it.

    Now in the real world where is is virtually impossible to have a pinpoint accurate fix, the sun travels so slowly across the sky that its movement is imperceptible and it is impossible to travel in a straight line, you could travel in a rough semi-circle from east to west (unless you were on the equator) but you would always be readjusting your direction to maintain a rough fix on the sun you would never be following it with pinpoint accuracy.

    It is becoming an interesting idea but as I live on the outskirts of West London the first part of my journey would be through London so I'm not going to bother.
    It doesn't matter how many times you fall down, its how times many you get back up that count.

    Hmmm that sure is interesting cb.

    Look whatever happens, I think it's safe to say you won't travel in a straight line, we live on a ball for starters. The earth is a sphere, in a wonky orbit around another sphere (the sun). Nature abhors a straight line, and if you introduce relativity, the whole of space time is slightly curved, so you could well arrive before you left, if you travelled far enough.

    then !!!

    Have you ever noticed that you cant walk in a straight line with your eyes closed.

    42 isn't anything special


    it is just the number of keep ups sheldon cooper can do

    and I can walk in a straight line with my eyes closed

    when I'm pissed....well it looks straight to me

    And have you noticed how hard it is to judge distance with one eye covered/shut...

    Well yes that is bloomin' obvious as you've lost binocular vision.

    I currently have a one eyed kitten, someone dumped in on the surgery doorstep with its right eye bulging out and I had to enucleate it (I could have euthanased it but that wouldn't have been right) and it now resides at home with the other waifs and stays. The point is that his vision is actually quite good as he probably never got used to having two eyes.

    However balance relies heavily of vision which is why we get motion sickness if we can't see were we're going. My balance relies very heavily on my vision, in good light I can ski/board brilliantly, in flat light by balance goes completely to pot and I'm floundering like a novice in fact I get motion sickness because by eyes are not telling me what my proprioceptors are sensing.
