This Space Documentary is about the life cycle of black holes. Dark centers of gravity that swallow everything in their path. What would you see if you got close? And fell past the point of no return. Into another world of twisted space and time. What secrets can we learn about the universe? On a journey to the center of a monster black hole.
In this space documentary they will talk about the following topics:
- Which star’s life cycle could end in a black hole?
- How does a black hole form
- How does a black hole die
- Lifespan of a black hole
- Life cycle of a star
- Who discovered black holes
- Supermassive black hole
- Event horizon black hole
The Life Cycle of Black Holes
A black hole is the most extreme manifestation of the universe. Matter and energy are so small that they are literally bursting out of the known universe. Scientists are beginning to think that this monster may have a strong influence on galaxies, the solar system, and space-time itself. With a new generation of high-tech laser systems and advanced telescopes in space, researchers are finally able to track the whereabouts of black holes.
Imagine traveling to the very center of our Galaxy. 26,000 light years away. And finding a vantage point on the night sky. You’d see millions of stars. And on the horizon a strange dark sphere rising. It’s a black hole. An object so dense nothing can escape its gravitational pull, not even light.
In nearly every large Galaxy, astronomers have found evidence of black holes, millions, even billions of times. The mass of the sun.
How did they form and get so large?
In the search for answers, we are beginning to glimpse at the forces that shape the stars, planets, even life. And now by tracing the life cycle of black holes, scientists are finding clues to the fate that awaits our Galaxy and the universe at large.
But how do you study something that, by nature evades, detection?
Sometimes the universe lets us in on its most mysterious workings. March 19th, 2008. Astronomers around the world receive an alert sent from an orbiting observatory called Swift. It had recorded a flash of gamma radiation, a kind of ultra high energy light that is the signature of a cataclysmic event. SWIFT automatically relayed the information down to Earth. And within seconds, robotic telescopes in North and South America turned their gaze on the rising light.
Meanwhile, at Giant observatories in Chile. And in Texas they zero in on it. Using specialized instruments to split the light into all its different wavelengths. That tells them how far the light had traveled to reach Earth. What they find is that it had come from seven and a half billion light years away. Halfway across the visible universe.
Other evidence from ground and space telescopes
Astronomers determined that the Flash was a narrow but intense beam of light, and that most likely it broadcast the birth of a black hole. This singular moment is the end point of a violent chain of events in the core of a large star.
By nature, black holes themselves do not emit any electromagnetic radiation other than hypothetical Hawking radiation, so astrophysicists looking for black holes generally must rely on indirect observations. For example, the existence of a black hole can sometimes be inferred by observing its gravitational influence on the environment around it.
The Event Horizon Telescope (EHT), run by MIT’s Haystack Observatory, is an active program that directly observes the immediate event horizon environment of black holes, such as the black hole at the center of the Milky Way.
