Why the Universe Has Weight: The Higgs Boson
The discovery of the Higgs boson was the Universe confirming that mass is an interaction, not given. On July 4, 2012, physicists announced the discovery of something they had been searching for over 40 years — the Higgs boson, a particle famously nicknamed “the God particle”. The Standard Model, the most successful theory of particle…

Why the Earth is Round: The Sphere We Call Home
Every curve on Earth is a signature of cosmic forces The Earth has a shape close to a sphere, and this has long been confirmed by scientific observations and research. Although in ancient times people believed the Earth was flat, by the Classical era scientists had begun to understand that our planet is round. The…

The $150 Billion Orbital Laboratory: Inside the ISS
Built through monumental effort, the International Space Station remains a symbol of how far humanity can go when united by a common goal. The International Space Station (ISS) is the largest and most complex structure ever built beyond Earth. It took humans more than ten years and a vast number of space missions to complete…

What Color is space, Really? The True Color of the Universe
In the spectrum of everything, even the cosmos has a favourite color. When we look at the night sky, we see only darkness (excluding the stars, of course). However, this doesn’t mean that space itself is black. This phenomenon is easily explained by the absence of light. Stars and galaxies emit electromagnetic radiation, which can…

What If Our Universe Isn’t Alone? Welcome to the Multiverse
Maybe somewhere out there, another version of you is reading a slightly different quote Have you ever wondered if our universe is just one of many? The idea might sound like science fiction, but in modern physics, it’s actually a serious possibility. It’s called the multiverse—a concept that suggests there could be an infinite number…

Casing the Stars: Interstellar Flights
The stars are not so far away — only our limits make them distant Interstellar flight is the travel of spacecraft (starship) between stars. It becomes possible when a spacecraft reaches the third cosmic velocity—that is, the speed required to escape the gravitational field of the Solar System. Currently, four spacecraft have exited the Solar System:…

Dyson Sphere: Architecture of a Bright Future
To catch the power of a star is to rewrite the destiny of a civilization A Dyson Sphere is a hypothetical megastructure project involving the reconstruction of an entire stellar system, which could theoretically be undertaken by an advanced civilization. The concept was proposed by American theoretical physicist Freeman Dyson as a possible explanation for…

The Concept of Naked Singularity: Breaking the Event Horizon
A naked singularity would be a crack in the fabric of the Universe, exposing the raw chaos of spacetime A singularity is a region of spacetime where the density of matter and the curvature of space tend to infinity. In other words, it is an infinitely small point with infinite temperature and density. It is…

Planets Without a Home: Starless Worlds
Some planets call a star their home. Others find their home in the infinite dark. Orphan planets (rogue planets) are the same as regular planets, but they are not gravitationally bound to any star or other planet. If such a planet is within a galaxy, it orbits the galactic core, though the time required for…

The Second Lost Sun: Nemesis
The universe is full of secrets, and perhaps our Sun has a long-lost twin lurking in the darkness In the 20th century, binary star systems were discovered—an astronomical phenomenon where two stars orbit each other around a common center of mass. It was hypothesized that our Sun might belong to such a binary system. This…

Is There a Man Buried on the Moon?
He dreamed of the stars but never reached them in life – yet in death, he rests on the Moon The first person to walk on the Moon was Neil Armstrong. But there is someone buried on the Moon who never even flew to space. The only person buried there is an American scientist named…

Falling Stars: Do They Really Fall from the Sky?
Not everything that shines in the sky is a star, and not everything that falls is lost “Falling stars” or “shooting stars” sound beautiful. But do stars really fall? In reality, what we call falling stars are actually meteors. These are small “rocks” that come to us from space. When they hit Earth’s atmosphere, they…
