^{-34}m

^{2}kg/s. For Example what if it were to be 1 somewhere? Hypothetical Question.

The same is true for G and c (speed of light)

These constants are not the parameters at all, they are just mere consequence of a bad choice of the units we used - meter, second etc.

What can be varied (and it is very interesting) if you vary parameters of the Standard Model.

I believe he means what if plank's constant was not a constant.

I went through some calculations with having planck's constant as 1, it gave me answer like as we will go lock the door knob, we would like scatter in parts. I greatly suspect my effort. Can this be true? super unusual phenomenons with changed value?

i meant that what would a world like parrallel world which has different planck's constant than ours.I believe he means what if plank's constant was not a constant.

1 in what units?

The value for h or c MEANS NOTHING. It just emans that we use some weird ad-hod definitions of METER, SECOND, GRAM etc. In feets per second c is different. So the next logical step is to use units, which are natural for the Nature:

http://en.wikipedia.org/wiki/Planck_units

There is an irresistable beauty how the formulas become very simple, getting rid of different powers of G, c and h.

You vary the parameters of the standard model and look (theoretically) what happens. Even question is theorectical, it is very important in understanding of the cosmology and life in our Universe.

But you can't change h in the same way you can change anything else. Of course, you can ask 'what happens if laws of our Universe were absolutely different. But it is a major change, not a minor change. (Max Tegmark call it level IV multiverse).

Again, h is not a constant or a parameter. Example:

We measure distance in meters, and surface- in square feets. Then the formula would be (h, w are height and width in meters):

S = 10.82 *h*w

The number 10.82 is a result of a bad choice of units. The same as h, G or c! In natural units the formula is

S = h*w

And the parameter simply dissapears. The same as h,G and c. So by asking 'what if h would be different' you are asking 'what if instead of 10.82 it would be 5.41' But it means that in natural units it would be

S = h*w/2

It is not just a different parameter, but different geometry and mathematics.

I think you shifted towards mathematical constants. I assume that the simplest definition of 'our' universe is to list the universal constants, for example charge on electron, c, G, h, magnetic constant etc. Constants like that.

Any change in these numbers should not be applicable for our universe but if parallel universe exist, some universe other than ours.

Physicist say energy equal to Ten to the 19 billion electron volts "The Planck Energy", will be able to get us to parallel universe. Who knows, we are still on a trail.

Here is a list of real parameters: http://en.wikipedia.org/wiki/Standard_Model#Construction_of_the_Standard_Model_Lagrangian

on the right of a page.

Add cosmological parameters (density, dark matter density, dark energy density) and you get a list of numbers you can vary.

Do you know that c = 299,792,458 m/s?

Do you know that this value is

So it is 299,792,458.000000000000000000000000000000000000000000000000000000000000000000000000000000000000... m/s ?

I think i got what you are saying as in E=hv ; h is only a number we use to convert v the frequency of radiation to Energy of a quantum. Or "result of bad choice of units". ok, these are the values that are there as we had to make formulas pass dimensional analysis.
