I'm sorry it has taken me a few days to get to answer you. The speed of light "speed limit" is not predicated on how much energy we can pump out of a rocket using current fuels. It is a primary function of Einstein's Special Theory of Relativity. So far, that theory has stood up to all tests. The apparent contradiction about space expanding, is that Special Relativity says that *objects* cannot move *through* space at faster than the speed of light (and in fact, anything composed of normal matter cannot travel *at* the speed of light either) ... but space itself, the invisible fabric of the universe, is not prohibited from expanding faster than the speed of light. When scientists talk about the expansion of the universe, they're referring to space expanding, not the *objects* in space moving through space.

I have had a number of conversations with "scientists" about this very subject, always to be told "That nothing travels faster than the speed of light" to which I have replied that firstly, our space travel is limited to burning fuels, be it gas or solid, and that only when we harness light and convert it to propulsion, and be able to travel at the speed of light, will we truly be able to travel in space. And secondly, our knowledge is limited to what we know, and therefore scientists are working with blinkers on, rather than assuming that object can travel faster than light. This comment has always been met with distain, and I'm politely treated as one would with a matric maths student talking to a child in kindergarten. If an object can travel faster than the speed of light, how do you measure the speed? What is it called? How fast can an object travel? how does it gain its velocity? And I might add - stop? And lastly, would the object cause the equivalent of a sonic boom as when a plane does going faster than sound?

You certainly are one lucky student. :-) He seemed like a very nice man. What did you get ask him, and what did he say to you? And are you enjoying the Pathways to Space?
