As all of us know space is space meanning there is no medium,at the same time heat needs a medium
Of courae electro magnetic radiation can transfer energy, means heat. Where is the problem?
Hi dear friend,
In general, transmission and distribution of thermal energy, is done in the following way: 1) Radiation, 2) Steer (energy) or conduction (energy), 3) Convection
Radiant heat transfer two properties: 1) on the procedure for transfer of material need heat to the environment, and it also takes place in a vacuum. 2) conduction and convection heat transfer is done in order to lower the temperature while radiant heat transfer can be made between the two objects are separated by a cold place even take place.
Many theories have been proposed for radiation. A theory of radiation energy packets called photons has linked to the publication. Another theory for radiation
Propagation of electromagnetic waves is considered. Heat radiation wavelength part of the electromagnetic spectrum that ranges from 0.1 to 100 micrometers and includes part of the UV rays, the waves of visible light and infrared radiation. This type of rotational and vibrational molecular motions, atoms and electrons of the material Achieved. Thermal radiation constant in all forms of matter (solid, liquid and gas) that has a temperature above absolute zero are carried out.

Theory from the ancients to the early 20th century assumed an essential medium existed through all space and vacuum that was necessary to transport light, heat, and gravity. Current theory rejects such a medium. No experiments have shown the effect of such a medium. Radiant energy was demonstrated to be corpuscular and to travel as an electromagnetic wave packet. No medium is necessary to transport corpuscular energy. Gravity is assumed to transport similarly, but is not electromagnetic. There is no unequivocal demonstration of a gravity wave packet.
Science and theory change with evidence. Anyone can challenge current theory, but will need evidence and a good explanation.
The solar heat energy travels through space in the form of electromagnetic waves enabling the transfer of heat through a process known as radiation.
