What have we learned from the black hole picture?

The EHT image could actually help scientists figure out exactly how galaxies grow and form, powered by black holes feasting on matter in their centers. The new photo also proves part of Einstein’s general theory of relativity (again), showing that the structure of the black hole is what Einstein expected it to be.

Why is black hole Photo important?

The image, the first-ever of a black hole, is destined for the shortlist of iconic images not only for what it can tell astronomers and physicists about how gravity and general relativity work under the most extreme conditions, but also because it captures what EHT Director Sheperd Doeleman called “a one-way door from …

Why study of black hole is important?

With the release of the first results in April 2019, the EHT has filled a significant gap in our empirical knowledge. Black holes are laboratories for testing fundamental theories that explain how the Universe works on the largest and the smallest scales (e.g., GR and Quantum Physics).

What can we learn from studying black holes?

“By looking at black holes, we can learn something about the evolution of galaxies and especially about the evolution of dwarf galaxies,” and perhaps even about the beginning of the universe, Zaw explained.

Why has it been difficult to study black holes?

The idea of an object in space so massive and dense that light could not escape it has been around for centuries. Scientists can’t directly observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation.

How can our knowledge of black holes help us understand space time?

According to Einstein’s theory, time and space, in a way, trade places inside the hole. At the very center of the black hole is where our understanding breaks down. Einstein’s theory of gravity seems to predict that time itself is destroyed at the center of the hole: time comes to an abrupt end there.

How do you explain a black hole to a child?

A black hole is where gravity has become so strong that nothing around it can escape, not even light. The mass of a black hole is so compact, or dense, that the force of gravity is too strong for even light to escape. Can we see them? Black holes are truly invisible.

What is the most important features of black hole?

The defining feature of a black hole is the appearance of an event horizon—a boundary in spacetime through which matter and light can pass only inward towards the mass of the black hole. Nothing, not even light, can escape from inside the event horizon.
