Microwaves from space can be detected from the use of radio telescopes. Microwaves have been used to test the big bang theory, and this Cosmic Microwave Background (CMB) radiation is a form of microwave that "fills" the universe, that is almost exactly the same in all directions and is not associated with any star or object. The CMB radiation is recognized to be radiation left over from the big bang, or during the early stages of development of the universe.

Panasonic offers a large variety of microwaves that fall into several large categories defining their use (countertop, built-in, commercial, etc). Of the basic countertop kind, the major differences are in the space present within the oven. The models first recommended by Panasonic are the NN-SD762S, the NN-SN942B, and the NN-SN942W.
Here is why we study space:Anything you study makes you smarter!Space includes the study of planets, and we live on a planet.Studying space helps us learn how the universe works.Studying space helps us look out for dangers like asteroids and sun flares.Studying space helps us find new places where humans can live so that we don't have to keep using up all our resources on this planet because we're so overpopulated.
Space-time is a concept used to describe a medium that extends throughout the universe. It helps explain how gravity bends light around large objects, as an object is said to warp space-time and therefore creates a distortion which light follows.
Yes, that is correct. The radiation generated by the Big Bang is called the cosmic microwave background (CMB). As the universe expanded and cooled over billions of years, the high-energy radiation transformed into lower-energy microwaves. Today, the CMB is detected as a faint glow of microwaves that permeates all of space and provides crucial evidence for the Big Bang theory.
Yes. Quite near to the beginning, in any case.
When examining the universe at optical wavelengths you tend to see bright spots (stars/galaxies) with huge expanses of black inbetween. However, at microwave wavelengths you see a background glow, known as the cosmic microwave background. This is a relic from the very early universe and can tell scientists a considerable amount about the early structure of the universe.
no, because microwaves do not take up space
Both the background level of microwaves and the continuing outwards expansion of the universe can be theoretically reversed to indicate a starting point in time and space from which all the universe began.
to try to find the beginning of the universe..to study the stars...
The universe IS space, plus everything that's in it.
Yes, radio static is a sort of afterglow fro the big bang, and can be detected in every direction in the universe.
gamma rays, x-rays, ultraviolet rays, visible light, infrared rays, microwaves and radio waves are all part of the electromagnetic spectrum. All these waves are released by different bodies in space. Gamma rays and X-rays can come from Quasars, neutron stars. Radio waves can come from even simple radioactive bodies (very unlikely to be detected).
The background radiation from the big bang
Everything in space is part of the universe or cosmos.the universe
yes most of the universe is empty space
