In a dream I had last night, we (humans) had discovered how to decouple mass from material, or reduce the coupling as desired.
It wasn’t high-tech, as simple as fire, just we had never stumbled upon it before. But all of the sudden building pyramids became a piece of cake.
Also easy and common place was “anti-gravity”, which really wasn’t anti-gravity at all, but rather reducing the mass of something until it became buoyant and floated.
If we wanted to go faster-than-light, reduce the mass to zero, and then any energy input resulted in infinite acceleration.
I think this will happen when the quarantine on Earth is lifted.
Perhaps when we fully understand the Higgs boson, we’ll be able to manipulate it.
