It takes a bold person to declare that interstellar travel is now within our grasp. Physicist Stephen Hawking has shown that he is just that, taking part in the Breakthrough Starshot initiative. The project has announced a $100m research programme to investigate the technology of using light to propel spacecraft out of the solar system to explore neighbouring stars.

For the first time in human history, interstellar travel is a realistic and achievable aspiration, and not just the playground of science fiction.

So what has changed that makes interstellar travel achievable? First of all, clear expectations. This is not about a great big spaceship with a colony of astronauts travelling for generations to settle a planet around a distant star. Neither is it about faster-than-light travel, tunnelling through wormholes to arrive at the other side of the universe in an instant of time. This is about technology that already exists, or nearly exists, being applied in new and exciting ways.

I suppose that us being in a simulation would answer Fermi’s Paradox very (disturbingly) neatly…

(Business Insider)

We trust the scientists around us to have the best grasp on how the world actually works.

So at this year’s 2016 Isaac Asimov Memorial Debate at the American Museum of Natural History, which addressed the question of whether or not the universe is a simulation, the answers from some panelists may be more comforting than the responses of others.

Ever notice how maps of the large structures of the Universe look like maps of the brain or a Pollock painting?

On the grandest scale, our universe is a network of galaxies tied together by the force of gravity. Cosmic Web, a new effort led by cosmologists and designers at Northeastern’s Center for Complex Network Research, offers a roadmap toward understanding how all of those tremendous clusters of stars connect—and the visualizations are stunning.

The images below show us several hypothetical architectures for our universe, built from data on 24,000 galaxies. By varying the construction algorithm, the researchers have designed cosmic webs that link up in a number of different ways; based on the size, proximity, and relative velocities of individual galaxies. I call it God View.

“Before, the cosmic web was more like a metaphor,” Kim Albrecht, the designer behind the new visualizations told Gizmodo. “This is the first time somebody has made these calculations and thought about it as an actual network.”

It may sound like sci-fi. But millions and millions of dollars are pouring into projects to mine asteroids and the moon. And with a space gold rush comes space pirates.

With trillions of dollars worth of minerals lying just under the moon’s surface or spinning around the solar system inside asteroids, space mining is big business.

Well, big potential business. No one has dug nickel out of an asteroid or scooped any tantalum from the lunar dust—at least not for profit. Before space miners can get drilling, they need to invent specialized industrial robots, set up orbital outposts and—arguably most importantly—convince investors, workers, and prospective buyers that space minerals are worth the cost and effort of mining them.
