Study Notes
- Black holes are regions in space where gravity is so strong that not even light can escape.
- The boundary of a black hole is called the event horizon.
- When something crosses the event horizon, it collapses into the black hole's singularity.
- There are several types of black holes, with stellar and supermassive being the most common.
- Stellar black holes form when massive stars die and collapse, while supermassive black holes exist at the center of large galaxies.
- Black holes are invisible, and scientists observe their effect on nearby matter to study them.
- Accretion disks and quasars are two ways scientists can observe black holes.
- Black holes were largely unknown until the 20th century, and the first one was discovered in 1971.
- Black holes are constantly warping space and time, altering entire galaxies.
- Black holes remain a fascinating and mysterious object in the universe.
Test your knowledge about black holes, regions of space with intense gravitational pull that not even light can escape. Learn about event horizons, singularities, types of black holes, observation methods, and their impact on galaxies.
