Astronomy - Research Paper Example The gravity would decrease since as you come closer to the center of the earth there is the decrease in gravitational pull. Therefore, the gravitational force would be weak almost the same as the moon’s centrifugal force. The moon would move away from the earth’s atmosphere since there would be less gravitational strength to keep it within the earth’s atmosphere. Furthermore, the weight of everything will be less by half since the gravity will decrease by half. Because of the reduced gravity the fish and other sea creature will float on water easily and would have problem sinking because of the in density of the earth’s matter. When the astronaut floats out of the international space station for him, to get back to the arm of the space station, he should throw away the set of tools he has. This concept applies the Newton third law of motion which states that for every action force there is the reaction force. So by throwing the tools away, the center of gravity of the set of tools and the astronaut will react against each other and, therefore, move in the opposite direction. This because the astronaut and the tools have the common center of gravity hence, they must remain the same. The tool set will move to the other direction as the body moves toward the space station. Hence, the astronaut will be able to rescue himself. The Newton third law is what works in aerospace engineering. It explains the generation of thrust by the rocket engine. James Webb space telescope is the next big thing in the field of astrophysics. I support it because Webb’s telescope has a combination of large apertures, diffracted image quality and infrared sensitivity over an extensive wavelength range that is not available from the ground or spaced-based facilities. In addition, Webb’s telescope has broad collecting than Hubble’s, and it is capable of extending to longer wavelengths in the infrared. Moreover, it
