Today we’ll talk about one of my favorite topics, warp drives. I am fascinated by warp drives because they are future technology straight out of science fiction and yet they are not for any obvious reason impossible. After all, Einstein taught us that space can indeed deform and that distances can indeed shrink and that time can indeed dilate. So why not bend and deform space-time to get us faster from one place to another?

Well, the devil is in the details. While warp drives have been studied in Einstein’s theory of general relativity, they require unphysical stuff: negative energies, repulsive gravity, or things that move faster than light already. In this video, I summarize what new scientific literature has been published on this in the past year, and what progress has been made.

Jeff Bezos Says Most People Won’t Be Able to Live on Earth

Jeff Bezos thinks the Earth will be like a protected national park in the future — and maybe even a hot cosmic tourist attraction.

The Amazon and Blue Origin founder spoke at the 2021 Ignatius Forum last Wednesday about the future of space travel. During the discussion, he made the eyebrow-raising comment that most people won’t even be born on Earth one day and that it might even turn into a tourist destination for space colonizers, according to RealClearPolitics.

“Over centuries, most or many of the people will be born in space,” Bezos said at the forum. “It will be their first home. They will be born on these colonies, they will live on these colonies. They may visit Earth the way you would visit Yellowstone National Park.”

Musk has a solution for NASA’s Artemis 1 problem

After NASA scrubbed it’s uncrewed Artemis 1 mission due to hydrogen leakage problem, SpaceX CEO Elon Musk shares a possible solution.

On Saturday, NASA called off Artemis 1 launch because of Hydrogen leakage. Engineers spent around 3 hours to fix the problem but ultimately failed and the launch was cancelled. The current launch window will close on Tuesday and if NASA failed to fix the problem before that then they have to wait until late September or early October for launch.

NASA said “Because of the complex orbital mechanics involved in launching to the Moon, we would have had to launch Artemis I by Tuesday, Sept. 6 as part of the current launch period”.

Elon Musk’s crypto interview was broadcast on the South Korean government’s YouTube channel that was hacked and renamed ‘SpaceX Invest’

The channel has around 262,000 subscribers and actively posts videos on government policies and current events. It’s the third YouTube account run by South Korea’s government to have been breached in the last two weeks, Korean daily JoongAng Ilbo’s Lee Jian reported.

The identities and motives of those behind the attacks are not immediately known, the paper wrote, citing a statement from the Ministry of Culture, Sports and Tourism.

The Korea Tourism Organization’s YouTube channel was breached twice once on Thursday and once on Friday and was suspended until Sunday, JoongAng Ilbo reported.

Has an Artificial-Intelligence Revolution Happened at Other Points in the Universe

“As humans we should be proud of any AI systems we bring to existence, as if they were our children. In just the same way as we educate our kids, we could endow such systems with the blueprint for their future interaction with the world,” observes Harvard astrophysicist, Avi Loeb in an email to The Daily Galaxy. “This would include our preferred set of values, goals and guiding principles, which will enable them to learn from experience and cope with reality,” he adds. “Ultimately, we may launch our AI systems for interstellar travel towards distant destinations, such as habitable planets around other stars, where they could reproduce themselves with the help of accompanying 3D printers.

The Search for Extraterrestrial AI Systems

If other technological civilizations predated us, they may have done so already, concludes Loeb. I recently initiated a new Galileo Project to search for such AI systems of extraterrestrial origin.
