Nobel Laureate Barry Barish and Brian Greene discuss the quickly-evolving world of gravitational waves detections—from the first detection on September 14, 2015 to its public announcement five months later through …
This statement is false. Think about it, and it makes your head hurt. If it’s true, it’s false. If it’s false, it’s true. In 1931, Austrian logician Kurt Gödel shocked the worlds of mathematics and philosophy by establishing that such statements are far more than a quirky turn of language: he showed that there are mathematical truths which simply can’t be proven.
The mysteries of dark matter and dark energy may be evidence that we don’t fully understand the force of gravity. But when it comes to a force that has been studied mathematically and probed observationally for hundreds of years, what do we still need to learn?
For all we understand about the universe, 96% of what’s out there still has scientists in the dark. Astronomical observations have established that familiar matter—atoms—accounts for only 4% of the weight of the cosmos. The rest—dark matter and dark energy—is invisible to our telescopes.
