“Light does not carry any heat energy. Light and heat energy are not the same.”


they are simply different definitions of the same thing- no matter what, they are both movement- both existence therefore unless you are referring strictly to differences in definitions they are exactly the same thing- movement...

existence is timeheat. one word...time is movement and heat is the amount or heat is movement and time is the amount.
therefore time and heat are the same thing or are 2 different things that are still the same thing (its a little tricky to understand)

light is timeheat- there's nothing faster than light therefore only nothing may carry heat - everything else is heat(or only nothing may exist at the speed of light) light does not exist at the speed of light because timeheat or light itself is the speed of existence- therefore light can not carry heat because it is heat (something can not carry something else unless there is a difference between something and something else- therefore since there is no difference between light and heat, one can not carry the other) once again, light can not carry heat- this is true but the only reason this is true is because light itself is heat, more specifically timeheat. there is only nothing that does not have light (hence only nothing may carry light or timeheat)- all existence has light and/or is light...all existence is movement and all movement is timeheat.

This statement can be observed in the temperature of the Space. The Space is cold.


this very statement contradicts your entire theory that light is not heat

This statement can be observed in the temperature of the Space.


if there is temperature then there is movement- if there is movement then there is heat- more specifically timeheat

The Space is cold.


and cold is temperature- and temperature is movement and movement is timeheat

“Light cannot burn. Temperature rises.”


light can not burn? -correct, but this statement gives off an erroneous idea (its the same as saying heat can not burn)... you can not heat up heat ...yes temperature rises but that is not the same thing as heating up heat it is simply heat moving at a faster speed therefore felt at a higher temperature (this may be some of your confusion) but if you could heat up light then there would no longer be light. if something continues to rise in temperature it will come to a point where it no longer gives off temperature hence no longer moves- it becomes greater than existence itself. light is existence therefore for light to burn creates a contradiction of the definition of light because in order for light to burn it would not be able to be light. therefore if someone can burn light it simply means that someone can stop light. but light can not be stopped by anything because anything is made of light  ...all of this may be a little hard to understand at first

in other words:

Light is a form of energy propagated by electromagnetic waves which is visible to our eyes. Light has several cousins (the same "stuff", but fundamentally differing in frequency) which are not visible, and are classified by human experience and technology.

One of light's cousins is called infrared rays. These we experience as one of the three modes of heat transfer called radiation, because all bodies not hot enough to emit light will emit infrared instead.

Heat is a dynamic energy, which is transfer of energy from a body hot in temperature to a body cold in temperature. Three modes of heat transfer exist: conduction, convection and radiation.

Radiation is via electromagnetic waves, primarily infrared, but for hot enough bodies like the sun, stars, light bulbs, fires, coals, and stove coils, it can also be some visible light.

Conduction is direct heat transfer through elastic collisions among molecules of bodies in contact.

Convection is a mode of heat transfer involving conduction between a solid and a fluid, but the fluid is also able to flow and carry heat with a bulk motion of heat. Should conduction effects not be considered, it is called advection. As a mechanical engineer, though I have been taught advection, I feel there is no purpose for even knowing that word. All convection must exist with conduction as well.
