ZAP Physics's video: Why Adding Velocities Does Not Work in Special Relativity

Special relativity is counter-intuitive in a lot of ways. But perhaps the result which is the most confusing for people seeing it for the first time is that nothing can travel faster than the speed of light in a vacuum. It seems straightforward that this can't be true, right? I someone is travelling at 0.5c relative to you and they throw a ball at 0.6c relative to them, clearly you see that same ball travel at 1.1c, and it is going faster than the speed of light! If this is the case, then special relativity has contradicted itself! So, we have to dive deeper into the assumptions we make and the framework we are working in when we assume that velocities simply add together like this. What we find is that there is a surprising rule for the addition of velocities in relativity!
