I look at life with detachment and distance, like a window shopper. Not only I study the window but also my own reflections in it.

The Unseen Dimension

Thursday, January 26, 2006 5 comments

We live in a four dimensional space-time. Three are spatial dimensions and the fourth one is Time. Have you seen time go by. The three spatial dimensions are quite accessible to our physical senses. Although we are sure that Time does exist, but we cannot physically connect with it. Its the unseen dimension.
String theory propounds a universe consisting of 10 or 11 dimensions. Are other 6-7 dimensions also as ephemeral as time. Once we accept that in our 4-dimensional universe one dimension is already ephemeral - its not difficult to come to terms with an idea of higher-dimensional universe. The additional dimensions can be curled up or extended finitely/infinitely.
********************************************************************************
I have written about the enigma of time before. Suffice here to highlight that time as a dimension is substantially different from other three dimensions.
Time is always flowing - moving, but the spatial dimension are stationary. Time is only uni-directional, but other dimensions can freely be traversed in either direction.
Still time and spatial dimensions are considered to be an integral whole space-time. Its only we, who try to discern different dimensions to it. For example fixing three mutually perpendicular dimensional axis is just an arbitrary exercise. For space the three dimensions are not distinguishable from others - the three are integrated enough - that we cannot de-integrate or differentiate them. We can substitute one of the spatial dimensions by any one of the rest of two - without changing the equations etc. So should be time. It should not be differentiable from spatial dimensions - we should be able to substitute any spatial dimension for time and vice-versa. But that is not true.
What gives?

    Your blog is a little bit creepy but sounds very intersting. Sometimes I also wondered about those dimension things. I am recalled of the flick " Time machine".

    can you slow or speed up time. i think so. when i am on my motobike doing 110mph i am 100% focused in the moment time "seems" to slow down, or thats my perception anyway

    dear sir,

    I read your article in Statesman ( It must have given by an honest person like you. Who else) on the corruption stories if IR. kudos to u. What you could not do in the day of your exit from ECR you accomplished that as a retired person.

    Do you think that unseen life forms are with us? Do they need us to live, like a' tick that needs blood. If so, then what do they eat form us? Are they unseen because they move faster then us, like a' ceiling fan spinning? If the blades on the fan move at a high speed then they are unseen.

    There are a number of things that I can not reconsile fully with all the above theorys, I see CYCLES in pretty much every thing their SCALE widely varrying from the unemaginably huge to the smallest sub atomic particle but what seems to be constant is a hidden FORCE, POWER or MECHANISM that regulates these cycles. Time is flowing but only from our human eyes I think time is not a true physical force that holds any structures together hence can not really be classed as a true dimension nevertheless a useful tool for us to measure reletivity.
