    I wonder why we are not tired after traveling around 40000 km (2*pi*6400) everyday with the earth.Even if we travel around 100 km in a bus/train we feel tired.But we are not tired after traveling with earth everyday.

    What makes us tired after travel? Is it the variation in the speed of the vehicle which makes our body to adjust with it?

    Travelling is always relative: we travel thousands of kilometers relative to a fixed point in space, but we hardly notice it. When I look at a car driving away from me, I am travelling relative to that car. That's how you should see the 40000 km: it's just as much travelling as looking at a car driving away from us, and just as tiring (that is, we don't notice it) :wink:

    How about it's nothing new, we evolved to live with it? we do not expend energy so three's no need to be tired. Travelling in a train might mean you are constantly alert using your muscles to counter any roughness in the ride especially if you are in britain, in India you would be using a lot of energy just to cling on to the outside of the train - who knows?

    ignorance may be bliss. maybe we require sleep for all this travel..

    in addition to earths spin we travel at 70k miles per hour around the sun, our sun is traveling at near 700k mile per hour around the galaxy core and even the galaxy is in motion.

    Is the 'edge' of the universe moving away from us at the speed of light? And could one say that 'we are moving away from the big bang'? Just trying to make the topic more interesting, if it makes any sense :wink:

    Technically Pendragon the jury is still out on that one.. there is evedence (as interpreted by us) that the universe is expanding, yet wherever you are in it you will perceive yourself as in the centre (if centre = bigbang location).

    But in this case the earth is rotating and we are also getting rotated with it, right? :?

    In order to be tired you need to exert some energy, mentally or physically, just where do you think this happens sitting in an armchair hutling through space at 87,000mph (or whatever) ???

    Hmmm...I think that is the point. :-D We get tired during bus/train journey due to the variation in speed,shaking etc, right?

    I don't have time to read all these posts so I'm sorry if I repeat someone's opinion.

    You wouldn't get tired during a long bus or train journey if it would be possible to work there, sit on a sofa and watch tv, eat and drink normally, do your hobbies and things like that.
    But if we just sit and look at the views in a bus, we get bored and therefore tired.
    Because we do all kinds of thing during the trip around the sun we don't get tired.

    Yes. Ship is a good example. (It didn't even cross my mind. )
    We can travell over seas without feelin tired.

    haha good one

    Leohopkins...What I meant was our body might be working against inertia caused by variation in speed and turbulances. Thus we end up in doing some kind of work which makes us feel tired. You are always welcome to correct me if I am wrong

    Yep you are wrong, it is the Earth that is doing the work for us. One of the main reasons for our energy loss whilst travelling would be the way our brain works....Our brain likes to take in and remember things and this requires energy, so vibrations aside, if you are travelling in a car you are seeing a lot of things at a much quicket rate......erm o,ay, thats a shot in the dark.
