So virtual particles are short-lived force carriers and electrons repel each other by exchanging a virtual photon.
Is that correct?

1. Since photons always move at the speed of light, shouldn't they be timeless and live forever, even though they're only supposed to be short-lived?
2. What if two electrons were separated by, say, a lightyear. How do these virtual photons live for a year in order to communicate repellency?
