How does heat move during radiation, convection, and conduction?

What do you think?

radiant=like a  flashlight & unaffected by gravity
convection= hot "air" rises, relative & dependent on cold air to displace it?
conduction= physical contact of cold to hot material

Agreed except for the unexpected and ad-hoc shot at general relativity?? Why state that light is unaffected by gravity?

Radiative heat includes transfer by light (including microwaves) and other particles.

radiant heat can travel down as well as up? unlike convective & conductive
