That's bad news for both the spaceship and the occupants on board. As the Alcubierre drive approaches the speed of light, photons from the cosmic microwave background – that's the leftover radiation from the start of our universe – will be absorbed into the starship. The next problem is keeping the energy going. "There have been proposals for alternatives, however, and if you can get that process going that is a technological issue." (Davis said the mass requirements range from the mass of the galaxy to the mass of the sun, but the principle still holds – it's a lot of energy.)īut say you can overcome that and start your space-warping. "The amount of energy to start the process would have to be on part with the total mass-energy of the planet Jupiter," Cleaver said in an interview. The problem begins with putting the Falcon into ignition. Cleaver has looked into some of these problems in collaboration with Richard Obousy (who was then his graduate student and now works with Icarus Interstellar) and Jeff Lee (who is also at Baylor.) Alcubierre drive limitationsīut there are a lot of problems that physicists need to figure out before we can use the Millennium Falcon to escape Kylo Ren. In the same way, a starship would stay still in space-time while space-time warps around it. The surfer is standing (relatively) still on their surfboard while the wave moves toward the shore. Imagine that the surfboard is a starship the surfer is the crew. In some cases, the nature of the item means that it is non-returnable, for example, due to hygiene/health and personal care/wellness/consumable nature of the product.In separate interviews with, physicists Eric Davis (at EarthTech International) and Gerald Cleaver (with Baylor University) independently compared the phenomenon to a surfer on a wave.
