I have this brain worm and it's been bugging me for ages. I don't know enough about anything to be able to answer this but when I heard a theory that an electron can be in 2 places at once but then appears to be in a specific location when observed I started wondering how this could be possible. Is it possible that electrons have negative mass and if so could they then travel faster than the speed of light? Ep = mga would look interesting too as both m and g would be negative values? HELP!!! Any thoughts?
