I can answer questions regarding Einstein's Theory of Relativity, particularly in Special Relativity. I will not answer homework questions or mathematical problems that require special symbols.
I have taught physics at the college level, undergraduate and graduate, for many years including Special Relativity. I have taught at Johns Hopkins, Case-Western, and MIT. I have also served as a staff member of the Commission on College Physics, which was supported by the National Science Foundation to recommend improvements in the curriculum of college physics departments in the US. I am also the author of a textbook titled Vector Calculus, which was used at MIT in the teaching of electromagnetic theory and relativity. My research interests were mainly in solid state physics, especially the properties of metals at low temperatures. I am listed in the publication known as American Men of Science.
I have dozens of papers published in the Physical Review and in the American Journal of Physics.
I hold a Ph.D. degree in physics from the Johns Hopkins University.

Rose, nobody knows how to answer this question. Unless the answer affects some experimental results, the answer is not important. So it wouldn't really be a physics question but a philosophical question
No, the mass of an electron is not infinite. I think you mean infinite density.
Infinitely small does not mean zero mass. Consider an electron. It has zero size; yet it has properties of mass, charge, and spin.
The space in between atoms is just there. It does not collapse, because there are forces that prevent two electrons from getting too close together. It is the electrostatic force that makes like charges
The size of an object is determined by the combination of the forces that keep atoms separated but at a certain distance. There is a long range force that keeps them together and short-range force that
