Which investigation shows the transfer is f gray energy in the absence of matter

Answer 1

One investigation that shows the transfer of gray energy in the absence of matter is the study of radiation and energy transfer in space. In space, there is a vacuum, with little to no matter present. However, various forms of electromagnetic radiation, including visible light, infrared radiation, and radio waves, traverse through space, transferring energy. This energy transfer can be detected and measured using specialized instruments and techniques, such as telescopes and spectrometers. These investigations help scientists understand how energy is transferred and distributed across different regions of the universe in the absence of significant matter.
