ok
i'm not good at physics and i haven't studied about physics yet but i have an idea
i believe it does, because i saw once in mythbusters that they are making a giant mirror. and they said that they are having a difficulty putting it up, because if they do, they are afraid that they may point the mirror to the house and may cause it the houses to burn.
so what i'm saying is, mirrors reflect heat, that's why they're cautious on making the mirror stand

Well, I have to quibble with some catagorical semantics here. You see, light is a material in the general sense of the word (it's made of particles), but heat is a property (like color or momentum). Infrared radiation, which *transmits* heat, can indeed be reflected by metalic mirrors.

If we really wanted to reduce heat on Earth it is feasible to build a large enough solar sail and place it much closer between the earth and sun's orbit so as to block or shade some of the light. If you put it too close to earth it woudl have to be well, the size of the earth. But if you wanted to reduce the size needed, you could move it closer to sun so a much smaller shade/blocker could be used. Also, if you read online, painting buildings white with reflective paint is known to reduce the heat inside of buildings and reflect that heat back up into the atmosphere.

Heat and light are not the same. Light is a wave of electromagnetic energy. Heat is a measure of the kinetic energy in molecules. A curling iron is hot because its molecules have great kinetic energy. So mirrors can't reflect heat like light. Instead, the mirror absorbs the kinetic energy being transferred to it.

Heat and light are part of the electromagnetic spectrum.
Therefore they can be reflected.
Movement of heat by convection or conduction is not reflected.
heat is infrared .
Shiny boards are put behind wood stoves to reflect the heat away from the walls behind a stove.

No mirror is 100% perfect, even the mirrors used in telescopes. Some light is absorbed. More important is the shape of the mirror, because imperfections in the shape of the mirror will push the photons in the wrong direction.

I say yes. So if we increase the worlds reflective capability, will that mean global cooling?

no, because light can only reflect thru the mirror

Heat due to radiation is reflected, heat due to convection is not.

IR reflectors are available which reflect heat.
They are used in many sensing applications.
