Hi this is my first post on this site and glad to be here! Ive only really started looking into maths and physics recently and feeling pretty overwhelmed at the moment. After reading about spacetime i was just chucking numbers around when i noticed somthing odd (to me at the time anyway). When adding the speed of the earth (e) to the amount of seconds it takes the earth to orbit (o) and then dividing by the speed of light (l), the result includes the speed of the earth. 486000(e) + 86400(o) / 299792458(l) = 486000.0003 Im sure its nothing or to do determining the speed of earth but its kind of bugging me. Is it just a random coincidence? Is the 3 of any significance? The only reason im asking on here is because ive looked over the internet to anything related to it and found nothing (also why its probably nothing). Thank you for any suggestions anyone can give.
