Hello, I've been thinking lately about the strange orbit speeds of galaxies and I came up with a little loony idea. What if gravity has a minimum attraction? To put it a different way, the attraction of any mass continues with a constant force no matter the radius after a certain distance. Stars at a "generic" orbital distant of 25000 light years from the center orbit at a "generic" 200 Kilometers per second speed, and so do stars with an orbital distance of 50000 light years. Going a little farther, that same attraction would continue all the way to the edge of the universe. So the force that cause any "generic" star to orbit at 200 kilometers per second would be the same force pulling on galaxies at the edge of the universe. Strong Nuclear Force is the strongest force, but its influence ends at the nucleus of a given atom. Electromagnetism has a defined strengths many times that of gravitation, but its influence is very limited beyond a certain distance. Could gravity have influence all the way to the edge of the universe, creating a micro-gravity constant force at a given distance and beyond? I have heard that there is a microscopic discrepancy in Newton's Law of Gravity. Just a curious idea, could that discrepancy be that gravity has a minimum force as well as a force. If all galaxies are alike then this minimum force could be measured, and if there is a discrepancy, this would be the reason why. Lambaste as needed, I'm just a layman and have no real knowledge of anything, thank you for your time.
