Summarize the main points from the following passage about black holes:

Black holes are extremely dense objects in space from which not even light can escape. They form when a massive star reaches the end of its life cycle and collapses inward under the force of its own gravity. As the star contracts, the gravitational pull becomes so strong it overwhelms all other forces. Eventually all the star's mass is crushed into a single point of infinite density called a singularity.

The gravitational attraction is so powerful that nothing, not even light, can escape once it passes a boundary called the event horizon - the point of no return. That's what gives the black hole its 'black' appearance - no light can reflect off it.  

Black holes don't just pull in matter - they pull in space and time as well. This creates a fabric of spacetime that is warped by the extreme gravity. The effects of this warping have been predicted by Einstein's theory of general relativity. Observing how light and stars are affected by being near a black hole helps confirm predictions of the theory.  

Supermassive black holes millions or billions of times more massive than the Sun exist at the center of most galaxies, including our own Milky Way galaxy. Scientists studying these colossal gravity wells are uncovering the secrets behind the growth and evolution of galaxies.

Black holes are extremely dense, massive objects in space with gravitational pull so strong that nothing, not even light, can escape once past the event horizon boundary. They form from the inward collapse of a dying massive star, with all its mass crushed into an infinitely dense singularity. Black holes warp the fabric of spacetime around them due to their intense gravity. This warping effect, predicted by Einstein's relativity, can be observed by studying how light and nearby objects behave. Supermassive black holes exist at the center of most galaxies, including the Milky Way, allowing scientists to study their role in galactic growth and evolution.

Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Please write a summary, in simple language, of who Daisy Eagan is using the following:

Throughout her multi-decade career, Tony award-winner Daisy Eagan has dazzled audiences from the stage to television and film, and with her writing. Next stop – time to take over the podcast world.
 
At age eleven, Eagan became the youngest actress to win a Tony Award for Best Performance by A Featured Actress for playing Mary Lennox in “The Secret Garden.” In 2016, Eagan returned to “The Secret Garden” to play Martha for the 25th anniversary concert production at Lincoln Center and at the Shakespeare Theatre in Washington, DC. Eagan also appeared on Broadway in “Les Miserables” and “James Joyce's The Dead,” and most recently on stage she starred in the First National Tour of Stephen Karam’s Tony-winning play, “The Humans.”
 
On television, Eagan can be seen on Freeform’s critically-acclaimed series “Good Trouble.” Additional television credits include HULU’s “The Path,” HBO’s “Girls,” CBS’ “The Mentalist,” “Without a Trace,” “Ghost Whisperer,” “The Unit” and “Numb3rs.”
 
A published award-winning writer with a loyal and growing audience, Eagan is a fierce fighter and activist for women's and LGBTQ rights. She is a rousing voice in political arenas and continues to fight for change throughout her literary career. She has written op-eds for publications including HuffPost and Playbill.com and had a column for USA Today Network’s The Journal News.
Response: Daisy Eagan is an award-winning stage and television actress, writer, and activist, and now can add podcaster to her list of roles. At only 11 years old, she won a Tony Award, she was the youngest actress to win such a prestigious award. She has appeared in several TV series, including The Path, Girls, and The Mentalist. Eagan is also an award-winning writer, activist, and a rousing voice in politics. 

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.
