Why ca n’t you walk through walls ? The question looks like an easy one and the answer fairly straightforward . You are solid . Walls are upstanding . Therefore , unless you have magical abilities ( or are Kitty Pryde ) , black market into a brick roadblock at King ’s Cross , London , will give you a dark eye and a sore head – not the way to room the Hogwarts Express .
But things get a little more complicated when you look at it on a microscopic point . We and everything else in the universe ( include the barrier at King ’s Cross ) are really just an hookup of atoms and atoms are almost whole empty quad . To be academic , they are 99.99999 percent empty space .
This intend that if you were to enlarge an particle to the size of a watermelon vine or football , the atom ’s electron and core would be too small to detect with the naked human eye .
So if this is the case , why ca n’t you take the air through walls ? YouTube channelLife Nogginexplains the skill beautifully and succinctly in the below spiritedness but , essentially , it comes down to a phenomenon foretell thePauli Exclusion Principle . This say that no two fermions ( a group of subatomic particles that includes negatron , proton , and neutron ) can be in the same state or same configuration at any one time .
When we imagine an atom , we might picture a neat diagram or model with a proton in the center and one or more electrons orbit it in even circles , much like the way a planet orbits the Sun . In world , movement of electrons are far more hit-or-miss , and while not directly comparable , they more resemble a shallow of Pisces than they do a major planet .
“ negatron swarm around that empty space in cloud formation , ” the storyteller explain in the video , liken them to blades on a rooter . When you expect at a stationary devotee , there is a lot of empty distance . rick it on , however , and it ’s a dissimilar story . The blades move at such a speed that it is as if they are everywhere at the same time – the same is true for the electrons in an mote .
This means that if you were to walk through a rampart , two electrons ( yours and the paries ’s ) would have to co - exist in the same place , albeit for a very , very curt space of clip . But , as per the Pauli Exclusion Principle , this is just not possible . Therefore , despite the fact that we are almost entirely empty space ( a intellect - boggle fact in itself ) , we can not walk through paries – or any other solid cloth for that matter .
