Thank you for that. That was awesome. There is alot that is supporting not being able to exceed C however, even the growing scientific community is talking about faster than light objects or events. IE Quantam Physics and two particles being linked together and it does not matter how far apart they are. If one particle moves the other does the same thing at the same time. So what I present is not new.

Rather most scientific breakthroughs have been achieved by thinking outside the box. And viewing something as simple as speed as a limitation is a little too "in the box".

Here is a good example. If the speed of light is the max any object (we will say a photon) can reach and that is relative to any point or object in space then what if you have two cars with cool little engines under the hood. They are X distance apart and traveling directly twoard each other at 50mph each.

Cumulitively they are approaching at 100mph.

Speed it up to 300mph each... you get 600mph closure. (Car A will see Car B approaching at 600mph)

Keep going to .25C... cumulative of .5c (no one has exceeded C yet...)

Now get to .5C each... You have a total of 1C for closure. According to Relativity this would be the limitation.

But neither one actually exceeded the speed of light. Bump the speeds up to just over .5C (which is still possible according to either newtons physics or relativity) and now you have a combined closure speed of >1C. Photons of light do this all the time say from one star to the next or even photons reflecting from the earth back in the direction of the sun. Or even simpler... two candles 5 feet from each other are emitting photons with a closure rate of the photons of 2C (excluding things like gravity, reflection, and refraction that may slow it down a little).

So >C is possible even with relativity.

You can counter this argument with Lenth and time contractions. To exclude those you have observer C that is standing equidistant from each object and measures each objects (A and B) approach and sees them both coming in at 1C apiece. He can logicly conclude that the rate of approach is 2C.... Fun stuff to think about.
Entanglement offers no way for information to travel FTL (indeed nothing is travelling FTL there). As for the closing speeds two objects traveling towards each other at velocities >.5c but <1c would seem to close the distance between each other faster than if one were stationary and the other travelling at 1c but only to an observer who isn't moving relative to them. From the point of view from one of the objects the closing speed is still less than 1c

Just because objects can have closing speeds in excess of that of the speed of light does not mean faster than light speeds can be reached
