No, the Earth does not get "cooked" by microwaves from outer space. The term "microwaves" in this context seems to be a misunderstanding.
Microwaves are a specific type of electromagnetic radiation that falls within the electromagnetic spectrum, with wavelengths ranging from about one millimeter to one meter. Microwaves are commonly used in microwave ovens for cooking food, but they are not the same as the microwaves that come from outer space.
The most prevalent form of electromagnetic radiation that reaches the Earth from outer space is in the form of visible light and other wavelengths across the electromagnetic spectrum, such as radio waves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays. These types of radiation come from various sources, including the Sun and other celestial objects.
Fortunately, Earth's atmosphere acts as a protective shield against many harmful forms of radiation, such as most ultraviolet and X-ray radiation. The Earth's atmosphere absorbs or scatters much of this harmful radiation before it reaches the surface. This natural protection is crucial for supporting life on our planet.
To summarize, while there are various forms of electromagnetic radiation coming from outer space, including visible light and radio waves, they are not the same as the microwaves used in microwave ovens. Earth's atmosphere acts as a shield, protecting us from most harmful radiation from space and ensuring that we are not "cooked" by it.
