Science View S2018E13 - Unraveling the Mystery of How Black Holes Grow

The gravity of celestial black holes is so strong that even light cannot escape. Black holes cannot be observed directly since they do not emit light, but recent research has discovered the possibility of numerous black holes existing throughout the universe. Their mass can range anywhere from tens of times to even millions of times larger than the sun, yet what accounts for such differences in size? This is said to be because black holes merge with each other as well as absorb surrounding gas, taking on enormous size. We'll introduce the latest research which seeks to explain the theory and mechanism behind this process.
