sorry, but no. mass is not a requirement for transporting energy

I am willing to learn! What is the carrier for energy and how?

photons are one thing that can carry energy but have no mass.

electric field interactions between electrons transfer energy with no
mass.

The photons and the fields are the math. In math are assumptions and
simplifications. Math is a piece to teach for students,

photons and fields are measurable things. equations describe the
observations.
