The typical office worker often has soreness throughout their body as a result of their sedentary desk jobs. Even young individuals may develop shoulder pain, which was previously primarily an issue for elderly people. Once shoulder pain creeps in, it is difficult to dress oneself, let alone move one’s body freely. It is also difficult to fall asleep. While the rotator cuffs are often naturally harmed as we age, repairing them has shown to be difficult.

So many of hopes and dreams for colonizing space rely on faster than light travel, and yet the ability to move between stars in moment seems against the laws of reality… but perhaps we can break those rules.

Our capability to render virtual realities better and better makes it seem likely one day we could simulate our world flawlessly, and perhaps our minds too. If so, perhaps we will in the future… and perhaps we already did in the past.

Physicists are building neural networks out of vibrations, voltages and lasers, arguing that the future of computing lies in exploiting the universe’s complex physical behaviors.

In Episode 3 we look at the concept of warp drives, a theoretical type of spaceship propulsion that warps spacetime to allow faster than light travel. We discuss the basic concept and the scientific and technological hurdles to developing it, along with clearing up many of the myths about it.

Black Holes are amongst the most destructive things in the Universe, but it may be that properly utilized, they might be the best places in the galaxy to live around in the future, and possibly right here in our own solar system too.

The Fermi Paradox contemplates the weirdness of our galaxy seemingly being devoid of intelligent alien life, but Many Worlds Theory, Multiverses, Parallel Universe, and Alternate Realities may radically alter our thinking on Aliens & SETI.

Episode 288; April 29, 2021
Written, produced & narrated by isaac arthur.
Script Editors:
Here’s an intriguing idea. What if you were informed that everything in your life was pre-planned? Even crazier, what if your history, present, and future are all taking place right now?
An incredible new theory established as the “block universe” theory asserts that time does not actually “flow like a river”; rather, everything is ever-present.
Dr. Bradford Skow, a philosophy professor at the Massachusetts Institute of Technology, proposes that if we “look down” on the cosmos as if it were a piece of paper, we would see time stretched out in all directions, just as we perceive space at any given time.
Circa 2021
Finding and fixing bugs in code is a time-consuming, and often frustrating, part of everyday work for software developers. Can deep learning address this problem and help developers deliver better software, faster? In a new paper, Self-Supervised Bug Detection and Repair, presented at the 2021 Conference on Neural Information Processing Systems (NeurIPS 2021), we show a promising deep learning model, which we call BugLab can be taught to detect and fix bugs, without using labelled data, through a “hide and seek” game.
To find and fix bugs in code requires not only reasoning over the code’s structure but also understanding ambiguous natural language hints that software developers leave in code comments, variable names, and more. For example, the code snippet below fixes a bug in an open-source project in GitHub.
Here the developer’s intent is clear through the natural language comment as well as the high-level structure of the code. However, a bug slipped through, and the wrong comparison operator was used. Our deep learning model was able to correctly identify this bug and alert the developer.
