In Einstein's Theory of Relativity nothing can travel faster than the speed of light. Everything is based off of the speed of light. But speed is relative to to the reference point your measuring from. Example if im in a car with a radar gun going 20 miles an hour an measure a car passing me at 60 its only going to say the car is going 40 MPH. Everything in the universe is moving in relation to each other. There is no static reference point for the universe. For all we know the whole universe could be traveling at 5X the speed of light but we are measuring is the points that we could see. Example if someone is in complete darkness an quiet an sees a light in front of them the light moves but so does the person in the same direction so the perception is the light isn't moving. So what if two objects are traveling towards at each other .75 speed of light from two different points in the universe. When measuring the speed the relative speed would be traveling torwards each other at 1.5 speed of light but measuring from the two points it would only be .75. So if speed is realative to the point that your measuring from I don't understand how this theory works. If anyone could help explain it to me this is for my own curiosity.
