suppose you are told that linear size of every thing in the universe has doubled can u test the statement by measuring sizes with a metre stick can u test is by using the fact that the speed of light is a universal constant and has not changed what will happen if all the clocks start running at half the sppeed

You can't do it using meter scale. If the velocity of light is constnt and clocks are running at the same speed then also we can check that (If they are spring clocks). If the speed of all clocks is halved then we won't be able to use the light method.
