"In the years since Miguel Alcubierre came up with a warp drive solution in 1994, you would occasionally see news headlines saying that warp drives can work. And then a few months later you'll see that they've been ruled out. And then after that you'll see that warp drives kind of work, but only in limited cases. It seems to constantly go around and around without a clear answer. What gives? It's not that we can't make up our minds, but it's that these calculations sit at the?very edge of our knowledge and abilities. And if I'm being honest, beyond them. So things are going to shift around quite a bit, and the truth is that we don't have a firm answer. For example, one set of calculations suggests that quantum fields living at the edge of the?warp drive?bubble essentially blow up to infinity as soon as you turn the thing on, which would be bad. Very bad." #warpdrive

"What's on and in a star? What happens in an active galactic nucleus? Answering those questions is the goal of a proposed giant interferometer on the moon. It's called the Artemis-enabled Stellar Imager (AeSI) and would deploy a series of 15–30 optical/ultraviolet-sensitive telescopes in a 1-km elliptical array across the lunar surface. A U.S. team of scientists and engineers led by Dr. Kenneth Carpenter at the NASA Goddard Space Flight Center, working in collaboration with Goddard's Integrated Design Center, has finished a 9-month feasibility study for AeSI and published its findings. AeSI is based on an earlier concept for a free-flying UV/optical space interferometer called Stellar Imager (SI). According to Carpenter, they watched the steady progress made on NASA's Artemis campaign to establish habitats and supporting infrastructure on the?lunar surface. The idea of a moon-based facility started looking much more feasible and competitive with the free-flyer." #lunartelescope #interferometer #moon
