We know that Einstein's famous equation describes the ‘energy density' of ‘matter' based upon the equation E=MC2.

It therefore logically follows that it is possible for energy to packed into a space defined by the variable ‘C squared'.

In a previous discussion we noted that it would appear to be true that the maximum velocity in the universe must be determined not by ‘the speed of light' but rather by the maximum frequency of light. If a mass of matter represents an organization of energy within a space which can be defined by the variable ‘C squared' then it is obvious that matter has not violated the constraints imposed by maximum relative momentum. Therefore we can be certain that the minimum maximum velocity in the universe is not the speed of light, but rather it must be ‘the speed of light squared'.

The speed of light squared is about 89 trillion kilometers per second (89,875,517,873,681.764). One light year is about 9 and a half trillion kilometers (9,460,528,400,000). What this means is that the maximum potential velocity in the universe must be about 9.5 light years per second. This is the most damnable of heresies. I understand that. But it seems to be true. It is the logical conclusion to draw. What this means is that we could send a probe to the far side of the universe (say about 15 billion light years) in about 50 years. Our fuel source would be the universe itself. We would rob some black hole in some galaxy of some incremental amount of momentum (the size of our probe being so tiny relative to the mass of that black hole).
