Cosmos (Greek: κόσμος meaning order, orderly arrangement, ornament) in the most general sense is a system in an orderly or harmonious universe. The study of the cosmos is called cosmology.

The cosmic microwave background (CMB) is electromagnetic radiation as a remnant of an early stage of the universe in Big Bang cosmology. In older literature, the CMB is also variously known as cosmic microwave background radiation (CMBR) or "relic radiation".

The CMB is a faint cosmic background radiation filling all space that is the oldest electromagnetic radiation in the universe, dating to the epoch of recombination. With a traditional optical telescope, the space between stars and galaxies (the background) is completely dark. However, a sufficiently sensitive radio telescope shows a faint background noise, or glow, almost isotropic, that is not associated with any star, galaxy, or other object. This glow is strongest in the microwave region of the radio spectrum. [more..]

Our bodies are mostly composed by approximately 70% water. If positive emotions, words, and feelings can change the physical structure of water, it means 'self-speech' has a direct impact on our body biologically. A number of studies say how thoughts, feelings, and emotions are something that we can not see, but we can feel, turn out to act as the ultimate control in the biological system of the human body.
