A Celestial Body from Which Not Even Light Can Escape
Black Hole (ブラックホール)
A black hole is a celestial object with such a strong gravitational pull that even light cannot escape it. The concept of black holes was first proposed by the British scientist John Michell and French mathematician Pierre-Simon Laplace in the 18th century. Later, in the 20th century, Einstein’s theory of general relativity laid the theoretical foundation, and astronomers began serious observations.
Because black holes do not emit light, their presence is inferred from the movement of surrounding stars and gas, or through the detection of X-rays emitted by matter falling into the black hole.
After over 200 years of theoretical development, on April 10, 2019, the Event Horizon Telescope (EHT) team succeeded in capturing the first-ever image of a black hole. The black hole is located at the center of the M87 galaxy, about 55 million light-years away from Earth. It is estimated to have a mass 6.5 billion times that of the Sun.
This was achieved using eight radio telescopes worldwide, combining their observational power to produce an image equivalent to that taken by a telescope the size of the Earth. This was a massive step forward in revealing the structure of black holes.

Playback! Blackbeard’s Power: Dark-Dark Fruit (Yami Yami no Mi)
Below, the manga panel and text refer to Marshall D. Teach (Blackbeard), a character from One Piece, and his ability granted by the Dark-Dark Fruit (Yami Yami no Mi).
The manga says:
“Blackbeard’s darkness swallows everything!!”
“Zuzuuuun!!!” (a dramatic sound effect)
The text discusses his power to manipulate gravity and darkness, likely in parallel to the science explanation of black holes above.
