My Visualisation In The Microscopic Level!

According to Bohr’s theory about an atom that an electron never loses its own energy. It can do so when it jumps from a higher energy level to a lower energy level. But we know that a substance especially a solid substance when get energy it becomes expand and we also know that when we cool down that substance it become compressed. But what happened when we put that substance in a very very cold place. According to my point of view if we take the object in a very low temperature it starts to lose energy in the form of radiation. 

So when we cool down a substance it become smaller than its real or original shape and size. That is why because on cooling down the substance the normal molecular distance is going to decrease. 

So it is always not impossible for an electron to lose its own energy because if we decrease the temperature of the substance into a very low level obviously the electrons comes closer with a very tiny distance to its nucleus. And also after a definite limit the electrons never lose energy or come close to the nucleus because if it regularly come closer to the nucleus the electron ultimately falls on the nucleus and this is not possible.
So thank you friends for give me this opportunity to share my thoughts and ideas with you. So my friends you try to understand this phenomena very deeply.
