câu 1
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
câu 2
A black hole can be formed by the death of a massive star. When such a star has exhausted the internal thermonuclear fuels in its core at the end of its life, the core becomes unstable and gravitationally collapses inward upon itself, and the star's outer layers are blown away.
câu 3
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.
câu 4
66 billion solar masses Currently the largest known black hole, powering the quasar TON 618, has a mass of 66 billion solar masses. TON 618's enormous bulk led scientists to speculate whether or not even larger black holes exist, and if there is any upper limit to their sizes.câu 5Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas.câu 6 ( tự làm đi )tui Tham khảo hết nha
