Can you write few examples which prove that laws of Physics is not constant?

Occam’s Razor suggests the simplest theory is most often true. Not a law. :)
We assume (and should) our locally well-supported theories work the same everywhere. Until evidence suggests something else.
Please be very clear - there are no “laws” of Physics. Only theories that work pretty well so far. The amazing thing is that we can apply our current theories to very distant observations, and they seem to still work. Mostly. Well, not quite.
There is breathtaking hubris in assuming we can understand the entire universe. The universe is many billions of years old (at least). We have observed the universe for an insignificant time. We have directly measured only a ridiculously insignificant fraction of the even the visible universe.
To presume from our microscopic perspective that we understand everything is very far beyond absurd. It is a bit amazing that the universe seems comprehensible, given our insignificantactual knowledge.
The enormous “WTF” in Physics now is under the labels “dark energy” and “dark matter” - as neither label means anything. All we know is our observations and our theory do not match. Kind of exciting, in a way. :)
Yes, as a Physics student (long ago), the measured “constants” bugged me. Are they really constants - or are they a local value, in time and place? Can we deduce the answers, or must we explore a greater segment of the universe, in space and time?
I suspect we are still a very long ways from deep knowledge of the universe. In fact, it is rather amazing we have at least a rough apparent grasp on so much, given we have only just started to look carefully.
Explanation:
Constants that are not constant are called variables. So the constants we have are the numbers that have never changed.
Constants that are not constant are called variables. So the constants we have are the numbers that have never changed.We used to think gravity was constant. Now we know gravity changes depending on where you are on Earth, and by the position of the moon and the sun. In fact, even the apple on your desk would alter gravity, along with the position of every atom with any mass anywhere in the universe. Since weight is a function of gravity, no two kilos were ever equal in the history of the meat market. But we’re okay with it.

You could measure pi [1] or the speed of light. Your phone and all technology that relies on physics are also constantly testing these constants.
