Does lightning have mass?
These charged particles excite the atoms in the air as they travel, which subsequently emit the light that you see. If to you, lightning is this stream of charges, then yes, lightning does have mass; it is made of electrons.
Does time exist for a photon?
Photons do not experience time. From the perspective of a photon, there is no such thing as time. It’s emitted, and might exist for hundreds of trillions of years, but for the photon, there’s zero time elapsed between when it’s emitted and when it’s absorbed again.
Is plasma a matter?
Plasma is superheated matter – so hot that the electrons are ripped away from the atoms forming an ionized gas. It comprises over 99\% of the visible universe. Plasma is often called “the fourth state of matter,” along with solid, liquid and gas.
Are there things that exist that don’t have mass?
In conclusion, yes there are things that exist that don’t have mass. Their invariant mass just has to be (theoretically) zero. , I know some physics, and I will answer what I can.
Does empty space exist without energy/mass?
If you consider a volume of absolutely empty space without energy, mass or particles it exists but can not be observed because there is nothing there. So the short answer to your question is that the empty space-time itself exists without energy/mass.
Is it possible for a particle to have zero mass?
Yes. If you consider the photon, which has zero mass, zero mass particles are everywhere. Light, which is made up of photons, is constantly shining down from the star we orbit to the little LED on Christmas lights. However, the photon is kind of odd when you describe it as being massless.
Can an object have neither mass or energy at all?
You correctly identify that objects that have neither mass nor energy are actually not anything at all. (Edit: because, for example, for them to have any effect on anything they’d have to violate the laws of conservation of energy or momentum.)
