In this episode, you will be able to: Uncover the potential for water sources on Mars due to newly discovered glacial remains. Dive into the intricacies of ultra-massive black holes and their impact on gravitational lensing and event horizons. Grasp the complex issue of time travel and how Earth's motion affects pinpointing landing locations. Explore the limitations of telescopes and active sensors in detecting objects beyond our solar system. Ponder the potential of the singularity, faster-than-light travel, and Cherenkov radiation in expanding our universe exploration. The resources mentioned in this episode are: Visit the phys.org website to read more about the discovery of glacial remains on Mars and the potential implications for future exploration. Learn more about gravitational lensing and how it can be used to measure the mass of celestial objects, such as ultra-massive black holes. Explore the Abell 1201 cluster and its ultra-massive black hole, which is 33 billion times more massive than the sun. Compare the ultra-massive black hole at the center of the Abell 1201 cluster to other known black holes, including the supermassive black hole at the center of our own galaxy. Research the different methods used to measure the mass of black holes, such as observing the velocity of material swirling around in their accretion disks.
