Hallo, Mich! You will probably be dissapointed by this answer to your question, as you will have to look for the door whenever going from one room to another for the rest of your life... It is truth that everything around us is made of molecules. But the molecules themselves are made of atoms held together by FORCES. Now if there are forces between the molecules, then you can collect a multitude of them in a SOLID object like wall, or Homo Sapiens. If the forces between them are feeble,then these molecules move around freely, almost not noticing one another. In that case they make up a gas, like air. Us people are made of molecules that hold to each other quite strongly. If that wasn't the case, you could literaly loose your head by doing let's say a somersault. When we walk through the air, the air molecules just flow around us, as our molecular bonds hold us together, but nothing holds the air molecules together. If you try walking through the wall you would first have to break the bonds between the molecules making up that wall, but in the process you would instead probably get torn appart by the wall as its molecules stick together stronger than the molecules you are made of... Mind you, according to quantum mechanics, there is a certain probability that you just pass through the wall unscratched, through the process known as 'tunneling'. However, it's very unlikely, but if you want to try your luck, I suggest you find an apropriate wall, put your back against it, start pushing and wait to see what happens... Duje
