because different scientists have different theories or explainatons on how the universe came into being so that's why the origin of the universe is still a question
hope this helps
The right answer is Electromagnetic waves can transfer energy through empty space.
Electromagnetic radiation refers to a form of linear energy transfer. Visible light is electromagnetic radiation, but is only a small slice of the broad electromagnetic spectrum. The propagation of this radiation does not need material to move.
if we take the example of solar energy, it spreads in space, the atmosphere until reaching the earth.
Once it reaches a material, it gives rise to many phenomena such as attenuation, absorption, diffraction and refraction, redshift, interferences, echoes, electromagnetic parasites and biological effects.
HI i was wondering 1 what engineer choice you are going for and two if this is what you mean. study hard to to bed early and make class . (im saying this becasue i have done it before :])
