only from warm objects to colder ones.
yes your mum had heat transfer with your dad

Heat transfer will only occur if there is a difference in temperatures. So if an object is high temperature but the surrounding area is also high temperature there will be no heat transfer.
It is radiation, as that is the only heat transfer that can occur in a vacuum (the universe).

Radiation is the only type of heat transfer that can occur through vacuum (space with no particles).

Heat is a transfer of energy from one object to another due to a difference in tempurature.
the atmosphere
There are three means of heat transfer, Convection, conduction, and radiation. All three occur to some degree in all heat transfer processes.
Heat transfer will only occur if there is a difference in temperatures. So if an object is high temperature but the surrounding area is also high temperature there will be no heat transfer.
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
Two objects must be touching and it has to transfer heat
