When black holes disappear, what happens to the stuff that fell in? Physicist Brian Cox explains. Brian Cox explains the significance of black holes in the quest for a quantum theory of gravity and a deeper understanding of space and time. According to Cox, black holes are intriguing because they challenge the compatibility of quantum theory and general relativity, creating a fundamental clash in our understanding of nature. Unifying these two pillars of physics is a major goal for theoretical physicists, and black holes are crucial in this pursuit. He also delves into the characteristics of black holes, describing the event horizon as a boundary between the external universe and the interior of the black hole. In conclusion, he says, black holes play a pivotal role in our understanding of the universe, pushing scientists to explore the nature of space, time, and the fundamental laws of physics. They offer a glimpse into something deeply hidden, potentially leading to a profound shift in our comprehension of reality. Read the video transcript ► https://bigthink.com/series/the-big-t...

NASA's Mars 2020 Perseverance mission captured thrilling footage of its rover landing in Mars' Jezero Crater on Feb. 18, 2021. The real footage in this video was captured by several cameras that are part of the rover's entry, descent, and landing suite. The views include a camera looking down from the spacecraft's descent stage (a kind of rocket-powered jet pack that helps fly the rover to its landing site), a camera on the rover looking up at the descent stage, a camera on the top of the aeroshell (a capsule protecting the rover) looking up at that parachute, and a camera on the bottom of the rover looking down at the Martian surface. The audio embedded in the video comes from the mission control call-outs during entry, descent, and landing.

We are going to the Moon, to stay, by 2024. And this is how. Special thanks to William Shatner for lending his voice to this project.
