Do Stars Die?
- Aditya Gupta - 25027, Grade X ... 23 February, 2024

Stars are giant cosmic objects, the glowing balls of gas. They are primarily the mixture of hydrogen and helium held together by the force of their own gravity. The reason behind their shine is the thermonuclear fusion reaction (hydrogen fusion) in their cores that keep stars bright. Whether or not the stars die depends on how we think of 'die'. Stars don't cease to exist in the way that living things do. Instead, they undergo a complex transformation when their fuel runs out. We should imagine it like a caterpillar morphing into a butterfly, but on a cosmic scale.

The entire process is finite due to the limited storage of hydrogen fuel in them. And when a star exhausts all of its nuclear fuel, its fate (end) takes a different turn. The fate of the stars undergoes some complex transformations and gets ended into a cosmic event known as supernovae, resulting in neutron stars or black holes in the case of giant stars, or in the case of smaller stars, a serene white dwarf.

In the case of smaller stars like the sun, they transform into a phase called “Red Giant” when those stars burn all of their hydrogen to helium. This process takes about 10 billion years. After the small stars get changed into a Red Giant, they become bigger and more denser than they are today. At this time it will start burning helium to carbon for a few hundred million years until it runs out of helium. And since it will not be dense enough to form other heavier elements like iron, the fusion process will stop. This will make the star collapse into its core due to inward acting gravity as there will be no fusion energy to stabilize its gravity. Then it will calmly shed its outer layers into space called a “Planetary nebula”. The white dwarfs are formed, an approximately earth-sized inner core. Other white dwarfs in binary systems may explode as novae. But they do not go on to form a neutron star or a black hole like other big stars do.

In case of larger stars, they experience more complex transformations and endings. When their fuel is all used, a “Red Supergiant” star is formed. The biggest stars in the universe are the red supergiant stars, about 1800 times the size of the Sun. Red supergiants are similar to red giants. They form when  stars run out of hydrogen fuel in their core. After using up its hydrogen fuel, it becomes a red supergiant. Due to its higher mass when the core collapses, the temperature rises quickly, which speeds up the helium fusion reaction. This fast fusion destabilizes the star. A massive amount of energy pushes the outer layers of the star outward, and turns it into a red supergiant. At this point, the star's pull towards its center is balanced by the strong push outward caused by the intense helium fusion reaction happening in its core. However, the star loses a significant amount of its mass into space. So, even though Red Supergiants are some of the largest stars, they aren't the most massive. Then the Red Supergiants exhausts the helium in their cores within one or two million years and then starts to burn carbon. This continues with fusion of heavier elements until an iron core builds up, which then collapses to produce a supernova. 

If the remaining star mass is more than three solar masses, the force is pushed out from the neutrons and that force (called neutron degeneracy pressure) isn't strong enough to stop the collapse. So the core keeps collapsing more and more until it becomes something called a black hole. A black hole is a place in space where gravity is so strong that nothing, not even light, can escape from it. It's like a super squished and dense point in space. And if the remaining star mass is less than three solar masses, a supernova changes into a neutron star. The core crushes down so much that all the protons and electrons get contracted into neutrons. Then these new neutrons stop the collapse and that's when we get a neutron star.

Hence, the stars in the cosmos end into three bodies: White dwarfs, Neutron stars and Black holes. However, stars have this incredible journey in space. They're not like living things that will suddenly “die”, but they go through some amazing changes, transformations and endings. When we look up at the night sky, each star has its own special story to share.

Dinosaurs: Earth's Legacy and Intergalactic Speculation
- Muskan Singh - 24023, Grade X ... 22 February, 2024

It isn't always unbelievable to think that dinosaurs might have unlocked the secrets of time tour and, upon discovering an approaching cataclysmic occasion like a meteor strike, took proactive measures to make certain their survival. They may want to have built significant spaceships to explore the vastness of the universe and search for a new habitable planet. The fossils and bones which have been observed on earth should thoroughly belong to the ones dinosaurs left behind, while the moon turned ingeniously created to function as an observatory to hold a watchful eye on their authentic domestic. This theory profits a few guide from the reality that even Mercury and Venus,  neighboring planets, lack moons.

Perhaps, Earth did no longer in the beginning own a moon. In this hypothetical scenario, it is doable to assume that, upon witnessing the evolution of people on Earth, the advanced dinosaurs may have lower back to our planet to increase their knowledge and help in our development. It is even attainable that we have encountered their teachings and observed the brilliant systems they constructed, inclusive of the historic Egyptian pyramids. The ancient Egyptians worshiped deities with human, animal, and reptilian functions, referred to as Annunakies. Could it be viable that these Annunakies had been truly the dinosaurs who arrived on Earth in a humanoid form to resource humanity and establish a connection with us? 

Perhaps the pyramids have been built as symbolic representations of the Earth's structure, designed by way of those exceedingly advanced beings. When analyzing the evolution of human beings, one cannot ignore the possibility that dinosaurs may also have also undergone their own evolutionary advancements all through the remarkable span of their 300 million year reign on Earth. The large expanse of time opens up endless opportunities and allows us to entertain interesting thoughts. For example, I recently stumbled upon a concept-scary video wherein a woman proposed the concept that the moon could potentially be a complicated spacecraft designed especially to study life on Earth, mainly humans. 

To my marvel, while she posed this query to astronauts, they seemed to lend credence to her idea. While I can not in my view affirm the accuracy of her claims, I discover myself leaning towards the belief that dinosaurs were far greater advanced than people in the course of their time on Earth. In the end, delving into the evolution of human beings necessarily results in the contemplation of the dinosaurs' very own evolutionary adventure. While the ideas provided here are only speculative, they invite us to consider the possibility that dinosaurs have been now not simply primitive creatures, but rather superior beings who may additionally have played a sizable role in shaping our world. 

The mysteries surrounding their life and their ability to interact with humanity hold to captivate our imaginations, urging us to explore further and embrace the enigmatic possibilities that lie past our cutting-edge understanding. Adding another layer of intrigue, latest clinical findings have suggested that our moon is showing signs and symptoms of rusting, which scientists attribute to a mixture of iron and water at the moon's surface.

However, this raises a complicated question: how should water exist on such an arid satellite tv for pc just like the moon? While I should admit that the validity of my theory is uncertain, I have meticulously connected various strands of studies and information to formulate this hypothesis. Taking into account the dinosaurs' sizable reign on Earth and the scarcity of concrete evidence concerning their lifestyles, it's reasonable to consider the belief that they advanced into particularly clever interstellar beings and feature seeing that determined a new domestic environment on every other planet that offers them comparable conditions to Earth. Thus, all that remains of them on Earth are the creatures that constitute their legacy, normally known as animals.

Role of Electronic Media for Educating People
- Saanvi Adhikari - 25058, Grad ... 21 February, 2024

We need not be irritated by the electronic media as it seems today. Electronic media such as the radio, television, and the internet have been educating people in politics in multiple ways: through news and views, and promoting public awareness. Although they are commercial media, they provide some services to people who are their target audiences. One of their major functions is to educate people. 

 

Educating people through News 

Electronic media deserve relative freedom to serve their audiences by providing news possessing ABC (Accuracy, Balance and Credibility) properties. When people get factual information in the form of news, they can learn many things. The news belonging to politics and current issues make people build up their opinion about political programs, leaders and the programs of the government as well. For instance, the news of a program organized by a major political party is essential to all the people. They can learn the principles of these parties by analyzing the news broadcast. In the elections, people can choose the candidates on the basis of the understanding they have developed. Similarly, people can learn the duties and rights of citizens by analyzing the news they get on the electronic media.

 

Educating people through Views

Similarly, electronic media educate the people in politics by broadcasting or telecasting or transmitting different views belonging to different political principles. For instance, the interview with a communist party leader on radio or television transmits the communist principles which people can compare with a democratic principles which people can compare with non-communist philosophies. Likewise, people can be exposed to political views if they make use of the internet because different views on politics can be found there. Furthermore, if people are equipped with the knowledge belonging to distinct views, they can understand what the rights to politics are and try to enjoy them in their real life. Thus, the electronic media can contribute to educate people in politics by providing different views. 

 

Educating people by Awareness 

Electronic media can educate the people by promoting public awareness through different programs. If people watch and listen to a program on television, in which the importance of voters is being discussed, they will be alert in the election and they understand why elections are important. Similarly, by getting different information on the internet, people can enhance the level of their awareness in politics. 

 

In addition to the ways mentioned above, electronic media can educate the people in politics through other ways, too. In our country, during Janaandolan-II , private TV channels were found promoting political awareness of the people by telecasting different news and views. Thus, we can conclude that electronic media can educate the people in various ways significantly.

खुसी पक्कै आउने छ !
- Parimal Prakash Nepal - 24084 ... 19 February, 2024

खुसीका पलहरू गुमे जस्तै लाग्छ अचेल कतै

म यहीँ भिडमा हराएझैँ लाग्छ अचेल कतै

सफल हुँदिनजस्तो लाग्छ तर

फेरि आशा संसार जित्ने छ कतै ।।

ठूलो भएसँगै के भयो खै 

खुसी खोज्दा खोज्दै हराइसकेको जस्तो लाग्छ

कसैलाई खुसी पनि दिन सकिन जस्तो लाग्छ

तर ठुलो हुँदै गर्दा बुझेँ 

यहाँ कसैलाई केही गरेर पनि खुसी पार्न सकिँदैन रैछ

बगेको नदी र अस्ताको घामझैँ

दुःख जाला अन्तै तिर चलेको बतासझैँ

खुसी आउँछ होला फर्केर धैर्यको मिठो फलझैँ

आउँदैन होला फर्केर गएको बतासझैँ ।।

खुसी खोज्दै जीवन बित्छ जस्तो छ

तर अब म हरेक कुरामा खुसी खोज्ने छु 

भोलि जिन्दगीको यति मीठो पल पनि गुमाएछु भन्ने नलागोस्  

चाहे परिस्थिति जस्तोसुकै होस्, 

मनस्थिति बलियो बनाएर अगाडि बढ्ने छु 

के थाहा खुसीले नि मलाई कतै खोजिरहेको छ कि ? ।।

Is AI Taking Over the World?
- Sangam Sedhai - 25002, Grade ... 19 February, 2024

The improvement and effect of counterfeit insights (AI) have started critical wrangle about and concern. Whereas a few specialists accept that AI has the potential to essentially progress human life by disposing of destitution, decreasing malady, and giving way better instruction, others have communicated stresses around the concentration of riches and control, as well as the potential for AI to be utilized in hurtful ways. The public's need for understanding of AI and its suggestions has too been highlighted as a concern. To guarantee the impartial sending of AI and the improvement of social bad form, there has to be an AI-literate open, guarantee diversity within the improvement of AI innovations, and center on AI instruction within the instructive division and public-facing media.

The transformative effect of AI on the world is evident in the areas such as financial improvement, healthcare, transportation, and security. For instance, a study by PriceWaterhouseCoopers evaluated that AI advances may increase worldwide GDP by 14% by 2030, with critical propels in several continents of the world. China, in specific, has set a national objective of contributing $150 billion in AI and points to lead in manufactured insights.

The potential of AI to revolutionize society, from progressing healthcare and transportation to profoundly modifying how we live and work, is highly recognized today. The advancement and application of this innovation are not without dangers. Concerns around work uprooting, predisposition, separation, and moral suggestions have been raised. It is emphasized that analysts, decision-makers, and the common open thought collaborate to guarantee that AI is created and utilized in ways that are ethical, open, and profitable to society. The benefits and risks of AI are a subject of progressing talk. The capable improvement and arrangement of AI will require conscious thought of its moral suggestions, potential dangers, and the requirement for open understanding and engagement. By tending to these concerns, it is accepted that AI has the potential to contribute to a distant, much better and more affluent future for all.

The effect of AI on society is multifaceted, and it is basic to carefully explore its advancement to guarantee that the benefits are maximized whereas relieving potential dangers.

Unveiling the Mysteries of Dream
- Pranisha Dhital - 24054, Grad ... 16 February, 2024

The first thing that comes to mind when I think about the word dream is, "Why do we dream?" There has been a lot of research conducted to determine why we dream, but the study of dreams is a dynamic issue, and the research continues to improve our understanding of this interesting aspect of the human experience. 

Sometimes I think that human beings only dream, or that other living beings also dream. And the answer to that question is that scientific research has said that some mammals dream like humans who have the same sleeping pattern like us and those who have a complex brain. Dreams are like magical stories that happen in our minds when we sleep. People have always been curious about them because they are mysterious and interesting. In this essay, I will talk about dreams, why we dream, what scientists say about them, and what they mean to different people.

Other things that come to mind when I think of a dream or dreaming are that sometimes we remember the dream that we dreamed about while we were sleeping, and sometimes I think that maybe it's giving some important message or hint that may be good or bad for the real world. Don’t you think so?

Sometimes I feel like I have experienced something previously, and I analyze the situation and come to the conclusion that I experienced the same thing in my dream. Such dreams are "precognitive dreaming." At first, I thought that it must be deja vu, but it was not. Now, what is a dream? A dream is a collection of pictures, emotions, thoughts, and experiences that occur unconsciously in the mind during various phases of sleep. Dreams may be vivid and intense experiences that feel genuine, despite the fact that they are created by the brain and do not take place in the actual world. 

I believe we do not dream every day when we are sleeping. At such moments, our brain rests well; yet, some days we dream while sleeping, indicating that our brain has not rested properly. How many times can you relate that the day we dream of something, the next morning, after sleeping for a longer time than usual, we feel tired as our brain has not gotten any rest?

Scientists have found that dreams usually happen when we are in the deep part of our sleep, called REM sleep. They think that dreams are our brain's way of organizing memories and feelings. While we still don't know exactly why we dream, scientists are working hard to understand it better. Some smart people who study the mind, called psychologists, have different ideas about dreams. Some think that dreams show what we really want or what we think deep inside. Others believe that dreams can help us solve problems or learn more about ourselves. It's like our mind is talking to us through dreams.

In different parts of the world, people have their own ideas about dreams. Some cultures believe that dreams are messages from gods or spirits. Ancient civilizations thought dreams had special meanings, like predicting the future. People's beliefs about dreams are shaped by where they come from and what they grew up learning.

Have you ever been in a dream and realized you were dreaming? That's called lucid dreaming! It's like being the director of your own dream movie. Some people can even control what happens in their dreams. This is a new and exciting area that scientists and dream enthusiasts are exploring to understand how it works and how it can be useful.

Dreams, the nightly blockbuster movies of our minds, remain a puzzling yet entertaining feature of our sleep. Scientists are the backstage crew, psychologists are the detectives, and cultures worldwide are the audience, each with their own critique. And then there are the lucid dreamers, rewriting the script with a touch of personal humor. In this dreamy circus, whether you're the star or just a spectator, may your dreams be as amusing as a cosmic comedy show. Sleep tight and dream light!
