Astronomical telescope, observing stars 2 billion light-years away. How could a physicist know that it was two billion years ago? Ask the Great God to answer
The time span of observation of a star 2 billion light-years away is very large. Physicians can determine which period it is in by analyzing the star's spectrum and brightness. The spectrum of a star was made up of the radiation produced by the movement of its atomic nucleus and electrons. When we observe the spectrum of a star, we can calculate its chemical composition, temperature, pressure, and other information. This information can help us determine the age of the star. When analyzing the spectrum of a star, physicists would consider the evolutionary history of the star, including its birth, burning, and death. By comparing the time of existence and evolution of different elements in the stellar spectrum, one could determine the age of the star. When observing the spectrum of a star 2 billion light-years away, physicists could determine that it was at a certain period 2 billion years ago based on the star's chemical composition, evolutionary history, and other information.

Author: The Whitest Crow The following is a detailed introduction of these novels: 1."Book of Troubled Times":"Book of Troubled Times" is a fantasy novel, but it's more of a martial arts novel. The author Ji Cha's writing was as excellent as ever, giving off a feeling of elegance. Compared to the bookish style of the previous books, the protagonist was more heroic and his writing strength was better than before. The plot was compact, with many foreshadowing, and the unfolding plot was fascinating. The characters in the book were drawn in three-dimensional, without facial makeup. The lofty sentiments of all kinds of characters were vividly displayed. Overall, this book was very impressive, and the recommendation index was.🌟🌟🌟🌖Whether it was from the content of the book, or from outside the book to life, emotions, psychology, society, history, they could all be inspired. 2."Spiritual Walker":"Spiritual Walker" was a modern sci-fi novel that stood out with its unique story and style. The storyline and character descriptions were quite outstanding. It had the taste of a high-quality product, but it also had the feeling of a fast-food article and a business article. It achieved unity in the contradiction. The overall style of the novel belonged to the sci-fi urban supernatural genre. It described a world where the spirit realm existed. The real world coexisted with the spirit realm world. The spirit realm would assign character cards to the people and arrange various missions. The male protagonist was an ordinary university student who became a Night Wandering God of the Lawful Class and gradually grew up. This book was tagged with the following labels: "Comes with Me","Sci-fi","Multi-story","Strange Thriller", and "Evolution". It was very suitable for readers who liked this genre. The author's writing style was excellent, and the story progressed layer by layer, which was very suitable for the rhythm of online novels. The portraits in the book were vivid, but there were some facial features, which was also the characteristic of the newspaper seller. 3."Tang's Table": Although the original ingredients had the original flavor of food, Yun Chu still believed that the most delicious food still needed to be divided, cooked, and handled. The food that was finally served on the table was the food that most suited the stomach of the Tang people. 4."King of Familiar":"King of Familiar" is a book that makes people's eyes light up. It has no traces of a routine, and the style of writing is relaxed and not oppressive, giving people a pleasant reading experience. This book told the story of a teenager and a husky in a new era. The author's writing was excellent and made people look forward to it. Overall, I give this book a recommendation score of 8.3. The setting of this exquisite book was very outstanding, and there were also many cool points. It allowed people to read many chapters in one breath. It was definitely a book that was highly recommended. 5."Fairy, Please Listen to My Explanation":[Ranking Index]: [Tagging Points: Xianxia·Sect·Imperial Court·Many Female Leaders·Anti-routine] [Work Status: 890,000 (Already on shelves)] [Female Lead Collection: Ran Qingmo, Tianyan, Su Jinxuan, Li Qingyan, Bai Muxi] The new book by a new author was a little slow to update, but the quality was guaranteed. It was definitely a new book at the immortal grass level. The author was Mi Tian Building. In his opinion, to be able to write such a book, such a style of writing, and such a plot foreshadowing, there was a high chance that he was a big shot. There was nothing to be said about the writing style. It was full of Xianxia flavor, full of classics, and detailed descriptions. It really looked like he was reading a script. The author might have been aiming for an adaptation, and he had a lot of ideas. In terms of the plot, the author had really done a good job of foreshadowing it. He did not completely forget his foreshadowing at the end like other authors. The plot was connected to each other, and there was basically nothing unnecessary. It really attracted the readers. The characters were full of the characteristics of Xianxia and many female protagonists. Basically, every female protagonist had their own characteristics. Interestingly, there were almost two female protagonists with each personality in the author's novel. One was complete and the other was still growing. It gave people the feeling that they were playing around. The funniest thing was that the author didn't stick to the usual routine. After killing the main character of the game, he didn't follow the plot. The female lead of the plot didn't accept him. Instead, many of them received a box lunch when they appeared. It was impossible to guess who the real female lead was, giving people a feeling of pity and certainty. National Forensic: National Forensic is a fascinating novel. The author, Shiniao Village, used his unique writing style to show the forensic profession vividly and interestingly. The main character was a forensic doctor who had just graduated from university. He constantly improved his skills by completing system missions. The author's understanding of the forensic science industry and humorous writing style made people have a strong interest in this industry. In addition, the book also incorporated some professional science knowledge, allowing people to have a deeper understanding of forensic work. The author's literary skills were interesting, and the image of the protagonist was also very likable. In short, this book was a daily novel about professional growth. Through the efforts of the second generation, he gradually became an excellent forensic doctor. Reading National Forensic Medicine not only allowed one to understand the forensic profession, but also inspired them to think about life, emotions, psychology, society, history, and other aspects. All in all, this was a very good book and I strongly recommend it to everyone. 7."Wait, Heroine": Quite chivalrous and tender, well written. 8."Mantang Colorful":"Blue Quality" It was the author's new book. The author had successfully become one of the Twelve Heavenly Kings with this book last year. He could be considered a great historical writer. This time, it was no longer the Song Dynasty, but the prosperous Great Tang. The protagonist had transmigrated to become the Du family's attendant. He was a handsome boy, but there was not much description of his appearance. In terms of the plot, it inherited the explosive opening of the previous movie, with ups and downs and brilliant scenes. The conflict was only unexpected and reasonable. The logic of the writing was smooth and logical. In terms of writing style, Cousin's pen was still strong enough. He outlined the character's image with just a few words. A clip could bring you a golden experience like a movie. Those who had read the last book should understand. The only thing was that for readers who did not know much about the history of the Tang Dynasty, the threshold of reading might be slightly higher. Other than that, there was nothing obscure in the text. 9:"Hidden Dead Corner": Get Lost New Book Fast forward to why you forced me. "Final Divine Duty":"Final Divine Duty" is a novel setting of science fiction + fantasy supernatural martial arts novel. The author, Tuoba Goudan, attracted the attention of many readers with his unique setting and wonderful plot. The advantages of this book were very obvious. Firstly, there were layers to the world view. The first ten chapters introduced the martial arts system by the protagonist's needs, the fifty-fourth chapter "The appearance of the evil cult" expanded the world view, and the eighty-fourth chapter "The Organization of Transformed Humans" was officially launched. At the same time, there was a hidden line "The archaeological work of the White Mountain era" to maintain suspense. Secondly, the character creation was naturally not exaggerated. Every character had a unique memory point, and the image would change according to the protagonist's cognition. Thirdly, the leveling rhythm was smooth and reasonable. The protagonist gradually became stronger, and the progression of the plot was also in line with the development logic. Finally, it's style "Beyond Time":"Beyond Time" was a refreshing classic Xianxia novel. The author, Er Gen, used his unique writing technique and cold killing decisiveness to describe the protagonist's path of survival in the apocalypse. In the story, the protagonist was decisive in killing and did not allow any existence that threatened him. As long as there was hostility, he would kill it on the spot. If he could not kill it, he would take out a small notebook to record it and find an opportunity to kill it. Although he was a lonely wolf, he had also received warmth and help from some people, such as Captain Lei, his master who was protective of his shortcomings, and his eldest senior brother who could eat anything. This kind of emotional interweaving and cold killing description made people feel nervous and excited. In the story, the author also raised a profound question: What is waiting for us outside of time? This was a question that made people ponder. In general, Beyond Time was a novel that was worth reading, especially for readers who liked ancient Xianxia novels. This book was definitely a good choice. [12: This Game Is Too Realistic] The fourth catastrophe, the players worked hard, but the pain was happy. 13."Red Heart Sky Patrol": A book friend recommended it. Food and grass turned into immortal grass. His results rose steadily. There would eventually be a time to kill gods and prove his Dao. [8 and a half stars!] Ring of Fate: The Secret World Part 2 In the year 1368, at the end of July, Crimson would descend from the sky. 'Squid's novel is still worth recommending.' "The Great Ming State Preceptor": The Great Ming State Preceptor is an admirable work. The author has shown his talent with a grand pattern and far-reaching ideas. This book was not only a novel, but also an explanation of political economy, sociology, monetary theory, and other theories in simple terms, allowing people to have a deeper understanding of history and reality. The author's writing was smooth and the plot was compact, making people unable to stop. I hope the author can continue to maintain this standard and bring us more exciting works. "Ascending on an Ascending Day":"Ascending on an Ascending Day" is a really good novel. After reading it, people can't help but want to recommend it to others. The author had done an excellent job in deliberately creating flaws, bringing many surprises to the readers. The sapling of the immortal grass in the story and the creation of the platinum author also left a deep impression on people. Especially Xu Ying, as a snake hunter, his diligence and the story of catching a different snake added more interest and suspense to the whole story. On the first day of the third month, the statue of the Divine Great Land woke up, which made the whole story even more exciting. The author was also very good at setting and dungeons, making people want to find out more. The only small regret was that the protagonist's cheat was a little too big. It was almost overwhelming, but it did not affect the overall reading experience. Overall,"Ascending on a Better Day" was a novel that was worth reading. For those readers who were in a shortage of books, this book would definitely satisfy their needs. "Who's in Love After Rebirth?""Who's in Love After Rebirth?" was a very good urban novel. The author was very good at describing the details, making people immerse themselves in the story. The image of the female lead, Feng Daidai, was also very likable. The summary was also very attractive. After his rebirth, the male protagonist took back the love letter he had given out and wrote down his desire to start a business and be rich and free. At the same time, he decided not to fall in love anymore. This book's recommendation index was three and a half stars. It was a highly recommended urban novel. The rebirth of the male lead not only gave him the start-up capital for his business, but also gave him the opportunity to re-examine his feelings. Although the early stages were somewhat depressing and survival oriented, the later stages were maintained quite well, making it worth watching. In short,"Who's Going to Fall in Love After Rebirth" was a very attractive urban novel. It was recommended to readers who liked urban novels. "Deep Sea Ember" was a fascinating Crusu novel. The protagonist of the story was a ghost captain, who was also a strange existence ranked among the top in the world. Even though the story was set in Crusu's world, the author did not make the story dark. Instead, it gave the readers a relaxing and enjoyable reading experience. The protagonist sailed on the seabed, solving mysteries one by one, filling people with anticipation. I strongly recommend a new book,"Sword of the Daybreaker." It was written by Toshimitsu and looks very good. The author of this book was the author of Anomaly, Dawn, and Deep Sea. He won the readers 'love with his unique style and creativity. The story was thrilling and irresistible. A book with big eyeballs is definitely not to be missed! This book perfectly combined the elements of resistance and harmony. It made people feel a chill down their backs and couldn't help but laugh. The main character's three views were very upright, but some of the plots in the story were a little scary. The plot has just begun, and there are some things that haven't been filled in, but I believe in Big Eyeball's imagination. The protagonist dressed up as Captain Duncan and began to explore this wonderful world, picking up crew members everywhere. This was a heartwarming story that made people feel happy. I like this book very much. I recommend it with five stars. Big Eyeball's work was definitely worthy of being sought after! From Anomaly to Dawn, to Deep Sea, to Deep Sea Ember, every work was fascinating. His works were full of humor and fun, making people laugh. I will always follow his works and look forward to his next work! "Cultivating in the Demonic Martial World: The protagonist transmigrated to the world of immortal cultivation and carried a treasure that could transmigrate to the world of demons and martial arts." However, it should be an incomplete version. There were fragments of the main character's treasure in the latest chapter in other worlds. It was possible that the copy would start a small dungeon mode again. 23，7，22 It felt different. "Who told him to cultivate!" [24's Book Collection Pavilion]"Who told him to cultivate!" Who sent this kid to harm our cultivation world! [A brief review] It was a relaxed and happy cultivation art. Lu Yang's transmigration into the Immortal Cultivation World could not be described as calm and uneventful. It could only be described as chaos. The author used cheerful language to tell the story of Lu Yang, a fun person. The relaxed style was very suitable for reading. His character creation was also extremely outstanding. Meng Jingzhou, who had a single spiritual root, and Barbarian Bone, a physics scholar…These characters seemed to be real and brought us joy. [Work Information] Title: Who told him to cultivate! Author: The Whitest Crow [Genre: Xianxia-Ancient Xianxia] [Tagged: relaxed and happy, silly and happy, immortal cultivation] [Status: In Progress (350,000 words)] [Ranking Index] [Reason for recommendation] Lu Yang had been in the Immortal Cultivation World for more than ten years. When he heard that the Immortal Gate was selecting disciples, he also wanted to try his luck. On the way, they met Meng Jingzhou, a disciple of an aristocratic cultivation family, and an extremely beautiful woman. The three of them immediately decided to travel together. On the way, Meng Jingzhou even shared the assessment content he had bought with them. When they arrived at the assessment site, the woman who was traveling with them soared into the air. She was actually the host of the assessment? The two of them were discussing how to cheat in front of the invigilator! Fortunately, the woman had let them go. When the assessment began, Meng Jingzhou had the single spiritual root that everyone was looking at, and Lu Yang had the rare sword seed that was naturally cheap (crossed out). The second test was the story of the three axes. Lu Yang had cheated the River Spirit of its axe and successfully cleared the level, while Meng Jingzhou had jumped into the river and picked up the axe… Ever since Lu Yang entered the cultivation world, the entire northwest of Shanxi Province (excluding) was in chaos.

Teenager Astronomical telescope
There were several factors to consider when choosing an astronomical telescope suitable for the teenager. First of all, whether the child was interested in astronomy and had the patience to observe the stars. If your child is interested and patient, you can consider buying binoculars. Secondly, he had to choose the right type of telescope. Refraction binoculars were easy to use. They had a large field of view and bright star images, but the color difference reduced the resolution. Reflecting binoculars had no color difference, but the image quality at the edge of the field of view was poor. Catadiopretic binoculars had the advantages of both refraction and reflection. They had a large field of view and good image quality, and the tube was short and easy to carry. Finally, you can consider participating in astronomy activities or summer camps to further develop your child's interest and knowledge.

Is the story of Big Fish Begonia about 4.5 billion years ago?
The main plot of Big Fish Begonia was a fictional story that took place in a world called "Floating Life Painting". In this world, humans and marine life coexisted, but in order to develop science and technology, humans had caused a large number of marine life species to go extinct, resulting in the collapse of the ecosystem. The story was mainly about a young marine biologist who had a life-and-death struggle with evil humans in order to save marine species. Although the story of Fu Sheng Hui took place 4.5 billion years ago, the plot of the story had nothing to do with this background.
