So it seems like a contradiction.
But what it is is that aluminum foil is both a really good absorber of heat but also a very good Emitter of heat.
It?s not that it reflects heat it actually absorbs it but it also emits it very well and it?s also cheap and it?s found in many places.
So the aluminum foil will absorb the heat but then it will quickly Emit it back out so in the universe the aluminum foil on the satellites are absorbing the suns heat but then it will Emit The heat into the universe and keep in the satellite cool
but when you use aluminum foil in your cake the heat has been absorbed into the aluminum foil and then it will let go of that heat into your cake so your cake can be thought of as the universe except this is a limited portion and so of course the heat warms up the cake .
In the universe of just dissipates.
