Why can't heat travel from the sun by convection or conduction?

Because there are no atoms to collide with to transfer the head energy from the sun, thus, there is no conduction. This is also the same reason that there are no convection currents in space; There are no atoms to collide with to transfer heat. Thus, the only possible way to transfer heat is by radiation.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
