Exploring the Supermassive Black Hole at the Center of Our Galaxy

What was the primary reason scientists could not capture an image of the supermassive black hole initially?

• It was invisible and only its effects could be observed.

• It was moving too fast.

• It was too far away.

• It was too small to be seen.

What is the Event Horizon Telescope (EHT) primarily used for?

• To explore the surface of Mars.

• To photograph distant galaxies.

• To study the sun's corona.

• To capture images of supermassive black holes.

How do scientists ensure the accuracy of data collected by the EHT?

• By employing atomic clocks for precise calibration.

• By using infrared technology.

• By taking images only during the day.

• By using high-resolution cameras.

What analogy is used to describe the difficulty of capturing an image of Sagittarius A*?

• Taking a picture of a mountain from space.

• Imaging a star in a distant galaxy.

• Photographing a donut on the moon.

• Capturing a comet in motion.

What is a significant difference between Sagittarius A* and M87*?

• M87* is located in our galaxy.

• Sagittarius A* is less active in consuming matter compared to M87*.

• M87* changes appearance more rapidly than Sagittarius A*.

• Sagittarius A* is much larger than M87*.

Why is it challenging to photograph a black hole directly?

• They do not allow light to escape.

• They are constantly moving.

• Their gravitational pull is too weak.

• They emit too much light.

What does the bright ring-like structure around a black hole represent?

• The accretion disk.

• The event horizon.

• The gravitational pull.

• The Schwarzschild radius.

How does the mass of Sagittarius A* compare to our sun?

• It is half the mass of our sun.

• It is one million times the mass of our sun.

• It is ten times the mass of our sun.

• It is the same as our sun.

What theory does the similarity in photos between M87* and Sagittarius A* support?

• The theory of evolution.

• The Big Bang theory.

• Einstein's theory of general relativity.

• Newton's law of universal gravitation.

What is the future potential of the data collected by the EHT?

• To improve satellite communication.

• To predict solar flares.

• To discover new planets.

• To enhance our understanding of black holes.
