Even if travelling at warp speed is theoretically possible, don’t the huge energy requirements make it unlikely?
When the idea was first proposed mathematically in 1994 it required a vast amount of negative vacuum energy which made the idea seem impossible. I did some work in 2011 and 2012 as part of the 100 Year Starship symposium and discovered ways to reduce the energy requirements by many orders of magnitude, so for a 10-metre diameter spacecraft with a velocity of 10 times light speed, I can reduce the negative energy needed.
How close are you to making this a reality?
We are very much in the science rather than the technology phase. We have got some very specific and controlled steps to take to create a proof of concept, to show we have properly understood and applied the math and physics. To that end we will try to generate a microscopic instance of a warp bubble in the lab and measure it.
