Why do stars orbit in our galaxy at the same speed?
Why do planets orbit the sun at different speeds, yet stars in our Galaxy orbit the center black hole at the same speed?
At what speed does our solar system orbit around the center of the Milky Way galaxy? Does a planetary orbit depend on the sun? Why doesn't Jupiter orbit the sun? Is the planet earth moving close to the sun with every orbit? The planets revolve around the sun without losing energy when gravitational force is acting on them .why? How is the motion of stars similar to the motion of the sun? What does the sun orbit? Does the sun orbit the earth? Why doesn't the earth accelerate towards the sun? Is the sun, and are other stars, in motion? What is similar to the motion of the stars and the sun? Do galaxies travel faster than the speed of light? Why is the earth's orbit around the sun almost circular? Why doesn't Earth crash to the Sun thanks to gravitational pull? How fast is our solar system traveling through space in relation to our galaxy's center? Why can't black holes be used to accelerate bodies to the speed of light? Why isn't the Sun orbiting Earth? What equation of motion does the Earth follow while orbiting the sun? Why so? The earth is spinning, and so are we at the same speed. Then why don’t things spin at the same rate up to the height of moon? Is the speed of an object near the black hole equal to the speed of light? Does the Sun actually move through the constellations? In terms of light speed, how far is the Sun from the Earth? Since earth is spinning and so are we at the same speed. Then why are things doesn't spin at the same rate up to the height of moon? Is the sun bigger than Jupiter? How is the orbit of Mars around the Sun determined? What is the principle behind why celestial objects like planets do not collapse into the gravity of the sun but revolve around it? Does the gravity of the planets affect the orbit of other planets in our solar system? According to string theory, why is earth rotating around the sun on an ellipse, while gravitation field of the sun should be almost perfect circle? How many times would a black hole with mass of Jupiter need to suddenly appear and disappear in front of spacecraft in order to reach speed 1/3c? Why can't we feel the momentum of the earth's spin, nor its orbit around the sun, nor the solar system's orbit around the Milky Way's center?
