Cosmic time-travel: The oldest galaxy

Galaxies are a fascinating subject of study and provide critical insights into the universe’s evolution. Studying galaxies has always fascinated astronomers, astrophysicists, and cosmologists alike. The oldest known galaxy in the universe is GN-z11, with a redshift value of 11.1, corresponding to a distance of approximately 32 billion light-years from Earth.

Constant mass or changing universe?

To inquire whether the universe’s mass is constant is a question that has perplexed many great minds throughout history. Indeed, the notion of a continuous universe was a prevailing scientific belief for centuries until later discoveries and theories challenged it. In this article, we shall provide a comprehensive and elaborate response to this inquiry by delving into the historical background of this subject matter, examining the idea of a static universe, exploring the implications of General Relativity and the Big Bang Theory, and ultimately addressing the question at hand.

The future of space exploration

Space exploration has become an increasingly significant area of scientific research and technological advancement in recent decades. With the progress made thus far, many wonder what the future of space exploration will entail. This write-up will delve into some of the possibilities in this exciting field and discuss the challenges that must be overcome to achieve these goals.

The atom is not a miniature solar system

Atoms have long been a subject of fascination for scientists and laypersons interested in natural sciences. At the dawn of the atomic era, many physicists and chemists used the metaphor of a miniature solar system to explain the structure of the atom. However, as our understanding of physics and chemistry has advanced, we now know that atoms are not, in fact, miniature solar systems.

Exploring a hypothetical Super-Earth

Adding a Super-Earth planet to our solar system would significantly affect the dynamics and stability of the existing planets. This report will explore the hypothetical consequences of adding a new giant planet between Mars and Jupiter, close to the Sun or outside the gas giants. A thought-experiment For several reasons, a Super-Earth is often used in computer simulations to perturb our solar system.
