Abstract: Recently, NASA’s Perseverance rover (equipped with the Ingenuity helicopter) landed on Mars and is investigating the crater Jezero, a place where scientists think they might fight find possible signs of life through the leftover marks of deltas and rivers and the rocks that might contain life-signalling minerals. The Perseverance rover is only a part […]
Shivam Dixit, Mallya Aditi International School, [email protected] Abstract – This paper aims to outline and analyze changes in the state of antimatter through the formation of the universe, exploring the relevant stages of cosmological history to study baryon asymmetry. Theoretical models which explain or address the observed phenomena of antimatter are explored. Finally, this paper […]
Abstract The colonization of Mars has been a topic of much discussion, and in recent years the media has had plenty to publish on this topic making this venture appear to be relatively easy. However, despite Mars being a neighbouring planet, it is an alien planet with an inhospitable environment. This paper — based on […]
By Chinmay Pala Abstract In this paper, the author explains how the Laser Interferometric Gravitational-wave Observatory (LIGO) detects gravitational waves and goes over the differences between initial LIGO and advanced LIGO. Beginning by explaining the formation of gravitational waves, the author then gives an overview of the history and locations of LIGO. In the main […]
Abstract No intelligent beings from space are present on Earth; no evidence of alien civilizations has been observed. The Fermi Paradox is one of the most mysterious questions in astronomy. In the past two decades, thousands of exoplanets have been discovered, and a fraction of them are habitable. The newly detected planetary system may provide […]
Abstract With the advancement of technology and scientific understandings, humans have been able to investigate many different astronomical bodies in outer space. In this review report, I explore some of the many worlds of our solar system in which humans could potentially colonise in future. It was Professor Michelle Dougherty, from the Imperial College London, […]
Image credit: Getty Images Aaditya Bhattacharya[1]* Abstract The article explores and explains the evolving concept of “gravitational waves”. It presents the importance of and recent progress in the contemporary knowledge of “gravitational waves”. It provides a brief overview of the interferometer – an instrument used to measure these gravitational waves. The article elucidates […]
Abstract This paper will look at the mystery of dark energy- what it is, how we conclude that it exists, and what more can we learn about our universe using this recent discovery. In the beginning of the paper, dark energy is introduced on a more theoretical/fundamental basis, where theories, concepts, and equations are used […]
Abstract. The Sun’s position in the sky changes when looked at during the same time each day from the same location throughout the year. The diagram showing how the Sun changes its position in the sky throughout the year is known as an Analemma. There are two independent factors that affect the change in sun’s […]
ABSTRACT For centuries, mankind’s understanding of the universe was mainly informed through religious beliefs. It was not until the 20th century, when Einstein published his paper on General relativity, in 1917, that humanity began to understand the nature of the universe in scientific terms. Einstein’s work not only formed the backbone of physical cosmology […]
By Waania Zia Abstract This is an article detailing the different models and theories of time travel, focusing on Einstein’s theory of relativity and Minkowski space-time, which is the combination of the 3 dimensional space with a 4th dimension of time. It delves into the development of time travel within science and fiction as well […]
By Katie Bean Everything in the universe is massive, without a doubt. Galaxies are rushing away from each other and stars are fusing hydrogen into helium at ferociously high temperatures and pressures. However, the once busy and blooming universe will eventually decay into a desolate, gloomy state after five distinct stages. What will happen at […]
Every star, planet and galaxy you’ve seen accounts to just around 5% of the total matter and energy in the Universe. Just 5%. The other 95% is made of dark matter and dark energy, both of which are equally mysterious and intriguing. That 5% baryonic matter was supposed to be relatively easy to find, but […]
by Hazal Kara Despite our Solar System’s close proximity to Earth relative to the rest of the universe, there is far too much that humans do not know about it yet. One of the biggest unanswered questions is whether or not there are planets beyond Pluto. As with most scientific mysteries, there is a lot […]
ABSTRACT While outer space might seem like a static, empty place, that is not true because of the sun’s dynamic nature, which gives rise to many phenomena. Their interaction with the earth’s atmosphere gives rise to what is known as space weather. The term “space weather” deals with conditions caused by charged particles ejected from […]
Abstract This paper explores different types of rocket propulsion systems and assesses their benefits and drawbacks. The paper also compares different types of rockets, such as Single Stage rockets and Two Stage rockets, before proposing a propulsion system for a future Single Stage to Orbit (SSTO) rocket. This system shall meet the requirements of both […]
Abstract Ever since the proposal of the Big Bang model, scientists have been puzzling over the expansion rate of the universe. What is the current speed of expansion? Is our universe expanding at an accelerating or decelerating rate? What does this tell us about the substances in the universe and our ultimate fate? In this […]
Abstract This article explores the effect of natural changes on the Earth’s climate, with a particular focus on the Milankovitch cycles and terrestrial albedo. Milankovitch cycles owe their name to the Serbian astronomer, geophysicist and mathematician Milutin Milankovitch who derived a mathematically developed theory suggesting the changes related to the Earth’s position relative to the […]
Abstract Mankind has always been interested in the vast void that we called space. Filled with endless unknowns and bizarre phenomena, people throughout history such as Aristotle, Galileo, and many more have made impactful developments in our knowledge about the universe. Ever since Sputnik 1, the first mission that successfully delivered a satellite into Earth’s […]
Abstract In the field of physics and astronomy, -body simulations are widely used tools to simulate particles under the influence of gravitational forces, and they are generally made using an algorithm that is almost a brute-force approach, as it computes all pairwise gravitational forces by solving for computational differential equation solutions using algorithms like the […]
