Ok I'm having trouble trying to figure something out. There will be a series of questions in this post. First of all, how fast exactly is the earth moving? Our average orbital speed is around 30,000 mph (correct me if I'm wrong) around the sun. The sun orbits around the center of our galaxy at approximately 217 km/s, so about 485,415 mph if my math is correct. And right now it's not exactly known, but the Milky Way is approximatley hurling through space at around 552 km/s or 1,234,789 mph So if I add it all together, that's about 1,750,204 mph. I guess my question is: Are we really moving that fast, total? I guess it's kind of like being in a car, and you're going 60 mph, but in your perception in the car, you're at 0. If earth is going 30,000 mph and the sun is pulling us around the galaxy center at 485,415 mph, and the galaxy is traveling us at 1,234,789 mph, are we actually moving that fast? Another question, is there a such thing as absolute 0 as far as speed is concerned? Is intergalatic space at a "stand still?" Is there any way to determine a 0? Also another question. If the speed of light is 186,000 mp/s (roughly) converted to roughly 669,600,000 mph, are we actually already traveling at a fraction of the speed of light? Last one!! : When a space ship escapes earth's gravitational pull and is in orbit around the earth in space, is the space ship actually traveling the 1,750,204 + their speed? Thanks for whoever answers these questions!
