    Speed
In summary, the conversation discusses the concept of closing speeds and whether two objects can appear to be moving faster than the speed of light relative to each other. The conversation includes examples such as particles in a particle accelerator and two spaceships approaching a target. While some argue that these objects can move faster than the speed of light, others argue that this does not violate special relativity because no mass is actually moving at the speed of light. The conversation also raises questions about information exchange and the possibility of objects still existing in their own space-time continua after being observed to collide.

Thank you for the math, it's really flattering. But no matter how you slice it, light is NOT going to go from A to B faster than c - unless you, too, wish to refute Einstein...

If anyone here is refuting Einstein, it is you.

The following quote is taken from his own book on Relativity:

http://bartleby.com/173/9.html

Now in reality (considered with reference to the railway embankment) he is hastening towards the beam of light coming from B, whilst he is riding on ahead of the beam of light coming from A.

In his own words he is saying that the closing speed of light is not always c.

Before you accuse people of refuting Einstein, be sure you know what he actually says first.
