Why should any body accept that order & disorder are different
quanties?

If you mean entropy, it is a defined quantity with a meaning in
science that actually has an effect on calculations.



It is manifestation of our pchycology. As a physical quantity there is
no difference.

Try passing a thermodynamics exam with that answer.

Both are different possibilties of arrangemnt of units

Example:- Drop a glass it breaks to small pieces, even broken pieces,
may look like some from of design for some people. So order & disorder
not necessarily different states. It is how we look at it & how much
benfit they give us

Thermodynamics is more concerned with stuff like microstates of a
system. If I recall correctly (unlikely; I hate thermodynamics :) ) a
glass has few. A vapourised glass has lots. It can be measured or at
least sampled.



Now Look at Super nova to be a disorder & formation of planets & next
genaration star from supernova to be order.

In other words, make stuff up.

we all know that supernova
& formation of planets is frequent phenomena.

Seems like it. I've heard it estimated that there is one supernova in
the universe every second, which is quite amazing if true.

Now if order & disorder
are physcical quantities than genaraly order does not come from
disorder it more often incerases with time. How is this ?

Because you're confused about thermodynamics, which says that the
entropy (disorder, if you like) of a /closed/ system increases with
time; you can't quantify your own terms of order and disorder and are
mixing them up with entropy; and you are using the weasel word
'generally', which means whatever you want it to.

Local increases in entropy (and in the universe, any region is a
locality) are not a problem for thermodynamics.

So I think order & disorder or not physical quantites which can be
calculated. there are our perceptions depending on how we look at them

If you don't understand science, you can't just declare it doesn't
exist.

Unless you're Michael Behe.
