The black hole, which appeared frequently in science fiction films such as Interstellar, is not that new, but it was never actually observed until now.

What does that mean?

It is a radio telescope that catches the radio wave coming from outer space and looks at the shape of star or galaxy.

If several radio telescopes catch radio waves all over the world, it has the same effect as using a giant radio telescope.

Since 2017, an international collaborative research team has mobilized eight radio telescopes in Antarctica, Chile, and France to establish a telescope performance that is as large as the earth.

Let's take a look at the universe with this telescope.

In the same spring these days, you can see the constellation Virgo, where you can see the Galaxy M87 covered with red gas.

As you zoom in further and fly at the speed of light for 55 million years, you will see a celestial body sucking all the light around you.

It is a black hole made after the death of the star. This is the first black hole in human history.

There is a black hole in the dark part, and all the light sucks, so the center is dark.

The mass of a black hole is 6.5 billion times the size of the sun, which causes the surrounding space to bend, and the light and matter are sucked in along the warped space.

At this time, enormous energy is emitted, which is captured by the radio telescope, which reveals the outline of the black hole.

Einstein proposed a general theory of relativity 104 years ago that might change the space of the city due to strong gravity, which means that the closer the time to the black hole, the slower the time flows.

Einstein's theories have been confirmed as the black hole, with its time and space distorted, is revealed as a visual.
