Black Holes

by James Barter

The remains of collapsed stars, black holes possess enormous gravities that pull n and annihilate any matter that strays too close. The latest evidence and theories for these bizarre objects are presented in this intriguing book, including how black holes were first predicted, how they form, their physical properties, and how scientists detect them. Also covered are the giant black holes now known to lurk at the centers of most galaxies and the possibility of using these objects as cosmic gateways.

کیهان مورد عجیبی ست ... مرتبه و اوردر عددها عجیب تر و برای جنون و مالیخولیا کافی به نطر میرسند و یک سوال همیشگی آنکه : خدای -متشخص انسانوار ، در صورت وجود - از این مقیاس ها و عددهای عظیم چه اراده کرده است؟
دنیای سیاهچاله ها و تلاش آدمی برای شناختش بسیار جذاب و جالبه... از آن جالبتر دنیای کرمچاله ها و امکان سفر در زمان و عدم رد آن توسط معادلات علمی ست...یک از مسایل جالب در باب سفر در زمان پارادوکس موسوم به مادر کشی ست:

اگرمن ماشین زمانی در اختیار داشته باشم باید بتوانم از آن برای بازگشت در زمان استفاده کنم و قبل از آنکه نطفه ام منعقد شود مادر خود را بکشم و بنابراین از زاده شدن خودم جلوگیری کنم

p.32 "Consider the [black hole:] lurking in the Milky Way's core. It is possible that several billion years from now, its gravity will draw our solar system, including Earth, into its black mouth."

So romantic ;-))))

It’s immediately engaging, for me at least. It’s engaging for me because I like science and space, so this appeals to both. It also gives information on what goes on in space, like how physics works, the life cycle of a star, and how the possibility of black holes got people to prove they exist.

The subject matter and themes are age appropriate because it talks about space which some kids and teens are interested in. It also doesn’t have fowl language, or doesn’t talk about inappropriate stuff. It does make you think about life because it’s something that is being talked about, which is space, and it applies to the topic because it has a life cycle like everything else.

There isn’t really a main character, just important people that gets mentioned, like Albert Einstein, Sir Issac Newton, Karl Schwarzschild, etc. They are realistic because they are real people, They are relatable because they are people, just smart people. They behaved like average people who ended up proving themselves.

I did get into the plot because it was something that has had my interests for a while now. I don’t have any questions for said plot because it’s very direct. It’s relevant to teen life, because it help decide what they want to study later in life.

The author made the plot interesting by giving information from the very start of the concept. The perspective was written from a third person point of view, because it is mainly about other people and their work. The message of the story is that space can be very interesting to a person.

The writing is descriptive because it gives details about the concept of black holes. The book is also descriptive because details about peoples’ work about black holes. Like Karl Schwarzchild who wrote information about the singularity.

The overall score I give the book is a 4. I give it this score because it’s very informative book, it teaches you a lot, but it’s not a more recent book. Also it gets this score because it should be longer.

The plot of the books is about physics, Black Holes how them being theorized led to them be proven to exist, and how they work, out a couple of options because they aren’t 100% sure.

My opinion of the book is that is pretty good, I just didn’t like how the glossary, notes, etc took up around a fifth of the book.

Great intro to black holes starting with Newton and gravity, and ending with arguments for and against the existence of wormholes. The kids enjoyed it and I learned a lot, too.

a great intro to people that, with no clue or knowledge of it, wish to learn what a black hole is — how it is formed and created, its development, and an interesting discussion on wormholes and its alleged existence, among other significant things to highlight when talking about black holes.

it is the perfect introduction for people that wish to start learning more about black holes.

Awesome book for beginners to understand such a complex topic ♡

Very short, most of the contents are covered by other popular books.

Black holes, one of the most mysterious entities in the vast, endless abyss otherwise known as space. Not too much is known about these beings but after reading Black Holes , I learned much. The topics of formation, history, how certain scientists contributed to black holes along with possible theoretical future uses were all divulged within.

Black Holes was written by Don Nardo, an American author, composer, historian, and award-winner. The author has written 400+ books and is well known for his many historical works. This book belongs to The Lucent Library of Science and Technology. I really enjoyed this book, because among the information was slight humor sprinkled in between with references to Star Trek and Star Wars. Plus, the information was simply insightful, striking a balance between understanding what was written without losing the complete and utter meaning of the information shared. It was written uniquely, with a quality that no other nonfiction book I've read has shared. I would recommend this book to readers of ages ranging 10-14 who have an interest or a passion for science and space. This book has definitely satisfied my passion for the unknown of the cosmos.
