Incorrect. A particle has mass, and cannot attain light speed.

Should have said "charged particle" rather than "particle".

What do you think. Is the electron a charged particle?

Maxwell assumed that the electricity is massles and incompressible.
He would be right if the electron is a charged particle.

have you ever measured the charge on an electron? that is a standard
college physics lab experiment, measure charge and mass and compare to
text book values. a very simple experiment actually, look up the
millikan oil drop experiment and give it a try. maybe you could get
together with art and go through a few of those simple experiments to
gain a better understanding of basic physics.
