Cosmologist’s Bizarre Adventure: Cracking the Mystery about Dark Energy

Posted Leave a commentPosted in Astrophysics

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 […]

The expanding cosmos

Posted 1 CommentPosted in Astrophysics

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 […]

Time travel: fact or fiction. A study on the scientific, social and historical impacts of time travel.

Posted 4 CommentsPosted in Astrophysics, Physics

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 […]

An examination of feasible rocket propulsion systems for a future single stage rocket

Posted Leave a commentPosted in Astrophysics, Physics, Space

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 […]

An analysis of the effects of Milankovitch cycles and terrestrial albedo on the Earth’s climate

Posted Leave a commentPosted in Astrophysics

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 […]

No More Rockets

Posted Leave a commentPosted in Astrophysics, Space

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 […]

The Effectiveness of “Pre-computed Vector Space and Interpolation” Method on the Computing Time for an n-body Simulation

Posted Leave a commentPosted in Astronomy, Astrophysics, Physics

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 […]

How to Look for Alien Life

Posted Leave a commentPosted in Astrobiology, Astrophysics, Other, Space

The possibility of extraterrestrial life has been discussed for centuries, in both scientific and fictitious work. But it wasn’t until 1992 that the first exoplanet (planet outside of our solar system) was detected, and 2001 that the first exoplanet in a habitable zone was detected [1]. This makes exoplanetology and astrobiology relatively new fields of […]

The 4th Dimension

Posted 1 CommentPosted in Astrophysics

Imagine a 4-dimensional object… Unfortunately, you soon realise that you can’t. But why? Our brains are not hardwired to picture anything beyond 3 dimensions. Life on Earth only goes until the 3rd dimension. The human brain cannot imagine something that it has never been exposed to (such as the 4th dimension). It would be like envisioning […]
