This is a short segment from an upcoming full release. I discuss at length how black holes warp spacetime and how they change the appearance of the background stars. • Light Path in Curved Space: Light always travels in straight lines, but in curved space, these lines can appear bent to distant observers. • Gravitational Lensing: The black hole’s gravity bends the light from distant stars, creating a distorted image. • Observer’s Perspective: Distant observers perceive a bent path of light due to their frame of reference in relatively flat space. • Gravitational Lensing: Curved spacetime distorts the path of light, creating multiple images of distant objects. • Light Path in Curved Spacetime: Light travels in straight lines in curved spacetime, but these lines appear bent to observers in flat spacetime. • Hubble Telescope Example: The Hubble Space Telescope, launched in April 1990, is an example of an application of gravitational lensing in astronomy. • Gravitational Lensing Observation: Hubble Space Telescope captured images of a distant quasar gravitationally lensed four times by a nearby galaxy, creating an Einstein cross. • Advanced Camera for Surveys Upgrade: In 2002, Hubble’s imaging capabilities were enhanced, leading to observations of galaxy clusters acting as gravitational lenses, distorting the light from distant objects. • Distorted Galaxy Appearance: The distorted appearance of galaxies, like the molten ring galaxy observed in 2021, is due to the path of light through space-time, magnified by gravitational lensing. • Einstein Ring Formation: The Einstein ring is formed by the background light of the Milky Way being bent by the black hole’s gravity. • Earth’s Orbit Simulation: Dr. Hamilton’s simulation shows Earth orbiting a black hole with a mass 2,000 times that of the sun, at a distance of three Schwarzschild radii. • Visual Effects of Curved Spacetime: The simulation demonstrates gravitational lensing, multiple images of Earth, and red-shifting due to time dilation. • Visualizing Black Hole Accretion Disk: The accretion disk around a black hole would appear squared off, dimmed and reddened on the receding side, and brightened and bluer on the approaching side. • Black Hole’s Impact on Earth: If Earth were orbiting a black hole, it would experience extreme tidal forces and be ripped apart. Materials from this area come from Andrew Hamilton's website about black holes:.
