We are about to see the first close-up pictures of a black hole | Design, Science and Technology | Scoop.it

The Event Horizon Telescope (EHT), a network of eight radio observatories spanning the globe, has set its sights on a pair of behemoths: Sagittarius A*, the supermassive black hole at the Milky Way’s center, and an even more massive black hole 53.5 million light-years away in galaxy M87. In April 2017, the observatories teamed up to observe the black holes’ event horizons, the boundary beyond which gravity is so extreme that even light can’t escape. After almost two years of rendering the data, scientists are gearing up to release the first images in April, 2019.

Is the universe fine-tuned for life to evolve?

Is the universe fine-tuned for life to evolve? | Design, Science and Technology | Scoop.it
Geraint F. Lewis’ day job involves creating synthetic universes on supercomputers. They can be overwhelmingly bizarre, unstable places. The question that compels him is: how did our universe come to be so perfectly tuned for stability and life?
 

For more than 400 years, physicists treated the universe like a machine, taking it apart to see how it ticks. The surprise is it turns out to have remarkably few parts: just leptons and quarks and four fundamental forces to glue them together.

But those few parts are exquisitely machined. If we tinker with their settings, even slightly, the universe as we know it would cease to exist. Science now faces the question of why the universe appears to have been “fine-tuned” to allow the appearance of complex life, a question that has some potentially uncomfortable answers.
