Gravity affects. Earth by warping space and slowing down time -- time runs slower in high gravitational fields than in weak ones, according to Albert Einstein’s general theory of relativity. The difference on Earth is very tiny, but for the first time, it’s been measured by putting atomic clocks on fictitious mountaintops and valleys and measuring the difference in the flow of time between the two. Physicists have now managed to measure this difference in the time it takes light to traverse a millimeter -- which sounds easy, but it is extremely hard! In this video, I discuss the fascinating experiment and the results of a paper posted earlier this month to the scientific preprint server arxiv.org, where researchers from the lab of Jun Ye, a physicist at JILA in Boulder, Colorado, measured the difference in the flow of time between the top and the bottom of a millimeter-high cloud of atoms. The work is an important milestone (millimeter stone?) toward studying gravity's intersection with quantum mechanics, two theories that are notoriously incompatible.

#briankeating #science #daverubin Watch the full video: https://youtu.be/AhYEFs2VX7Y Dave Rubin of The Rubin Report talks to astrophysicist, “Into the Impossible” author and UC San Diego professor Dr. Brian Keating about the dangers of treating science as a religion, how we became slaves to meaningless phrases like “follow the science”, and why imposter syndrome has plagued so many Nobel prize winners. In this clip Brian shares the importance of the discoveries of Nobel Prize winner Sheldon Lee Glashow and why his explanation of electromagnetism is so important. Brian also explains why there is no such thing as “follow the science” and why you should be skeptical of anything where 99% of scientists are in agreement. The process of science never reaches a single final answer. Brian also discusses the significance of Malcolm Gladwell’s 10,000 hour rule and how we can achieve mastery.
