Using negative matter to go faster than light (for example in a warp drive) is not necessarily about matter moving through space at faster-than-light speed. It’s about manipulating space so that it propels the ship along without violating the cosmic speed limit. In the case of a warp drive, negative matter would be used to expand space behind the ship and contract it in front of the ship to create a forward motion — kind of like the ship is being moved along on a conveyor belt. Einstein said that nothing traveling on the conveyer belt could go faster than light, however the conveyer belt itself can go as fast as it wants. Similarly, anything traveling in space is limited by light speed but the contraction and expansion of the fabric of space itself is not limited by any speed. That is how warp drives and other negative matter ships can travel so fast without ever contradicting relativity.
In the case of the Nullor drive, the speed limit is maintained by the fact that negative matter has negative kinetic energy and negative momentum, meaning that the speed of the ship never mathematically exceeds the speed of light because the positive kinetic energy is balanced by the negative.
I also don’t mean to feed into any fantasies about science. It’s why I’ve made it clear that negative matter is entirely hypothetical but possible by the equations of physics. The same is true for wormholes, the multiverse, and constituents of nature such as the strings in string theory. I believe it’s important to present all ideas to the public in order to keep alive curiosity, imagination, and an open mind to the nature of reality. Some theories are more far reaching than others but negative matter is interesting to talk about. It has great potential. I don’t believe anything is lost by opening up a conversation about it so long as it’s made clear that we’ve never found it and these objects remain hypothetical.
Thank you for reading and commenting on my work. It’s always great to discuss these ideas.
