Hello World! I'm new to the forums and have been pondering something for about a year now. I made up this theory to travel at the speed of light. I'm only in eighth grade and will be taking Advanced Physics next year so I don't know much right now but here it goes My theory is this: You take a conveyor belt that can move extremely fast. Lets say 1000 mph. now take another conveyor belt that travels really fast and stack it on top of the first one. So now relative to the ground, your traveling 2000 mph (I'm pretty sure anyway). Continue by stacking conveyor belts until your very close to the speed of light. Now put a fast train on top of all the conveyor belts then get in. Would you be traveling at the speed of light. Please explain. You could also consider that the conveyor belts are very light weight.
