创建一个关于宇宙中黑洞的短片。短片不得超过3分钟，需要在视频中提到黑洞的定义，它们是如何形成的，以及黑洞对周围的星系造成的影响。
那么，请观赏我们制作的黑洞短片：

Black holes are formed when massive stars run out of fuel and collapse under their own gravity, becoming so dense that not even light can escape their pull. They are invisible, but their effects can be seen in the way they distort light and cause objects to orbit around them.

Black holes can have a profound impact on their surroundings. They can consume nearby gas and dust, releasing tremendous amounts of energy in the process. They can also affect the movement of nearby stars, often causing them to orbit around the black hole in tight configurations.

At the center of many galaxies, including our own Milky Way, lies massive black holes weighing billions of times the mass of the Sun. These black holes can control the growth and evolution of their host galaxies, influencing the formation of new stars and the distribution of material throughout the galaxy.

Black holes are one of the most mysterious objects in the universe, challenging our understanding of gravity and the fundamental laws of physics. As we continue to study and learn about these fascinating objects, we unlock new insights into the nature of the universe itself.
