The celestial bodies in the universe is in after achieving certain quality, can appear bulbiform, star need not say oneself, solid state planet also can be in oneself is in condition of fluid static equilibrium below gravitational action, thereby evolution is glomerate celestial body.
Macrocosm is 1000 appearance in our eye 100 condition, gorgeous, but microcosmos, be in especially atomic measure level, cannot be experienced directly with our sense organ, those microcosmic particle, its applicable physics law is as disparate as macrocosm also, also the experience with respect to what cannot use macrocosm and feeling go apply mechanically. Still can unite quanta faultlessly now without which theoretically mechanical with the theory of relativity.
In microcosmos, the quantitative class of atomic diameter is 10^-10m about, this measure should want than the wavelengh of any light-wave many small, also cannot observe through electromagnetic wave (the diffraction of referenced light) ,
So, on this measure, microcosmic particle is to do not have " color " and " appearance " , atomic size is by " around " wear what the electronic orbit of nucleus decides, and the electron also is not actually circling the earth like the satellite in that way circuit encircles rotate, orbit discretion of the electron is by its " energy level " decision, it is between each energy level transition, electronic orbit is not a circle, the electron in course the position that go up is random, it is cloud of a probability actually, and this electron cloud can say is what to do not have " appearance " , we just describe the method that atomic simplifies one kind to go to the lavatory with the circle.
As to in smaller measure, for instance proton neutron and electron, the quantitative class of its size is in 10^-15m-10^-16m, so that the 10^-18m of quark is the following, the end of material and energy is so not apparent, bowstring theory exceeds in a branch of academic physics in, the basic particle of nature is not electron, photon, neutrino and quark and so on any more have " size " the particle that order state, however a root is very small very small linear " bowstring " , what spend in Gao Wei is spatio-temporal in the chord that vibrates with different frequency, shake means and those who shake frequency is different the basic particle that formed different character, and these bowstring do not have bulk, can be the energy in the space only.
Say so, atom does not have specific figure, resemble be quark cent red, green, blue wait for color, it is physicist names one kind of microcosmic to these particle only, do not represent actual color, same, we see in all sorts of popular science information atom is of pellet form also do not show atom is that appearance, it is one of means that state to particle only.
