Hello, Just one quick question. What happens to the molecular structure of an object if it moves close to the speed of light? Does the high speed affect the atoms, protons, neutrons, electrons, molecular structures? Does the density/thickness of the object increase? Or do the protons and electrons contract as well? Also, if the mass increases because of the high speed, how does it affect the molecular structure? How can it have bigger mass then? Does it have more atoms and molecules then? Regards.
