Introduction to Propulsion Definition and Importance Propulsion is the mechanism by which a vehicle is moved forward. In the context of aerospace engineering, propulsion systems are critical for the operation of aircraft and spacecraft. These systems generate the necessary thrust to overcome drag and gravity, enabling vehicles to achieve and maintain flight. The importance of […]
‘Substantial’ Number of Wandering Black Holes Could Be Roaming Galaxies
Scientists have long been aware of the existence of celestial entities of such gravitational intensity that no light can escape their perimeters. Such entities are called black holes. It’s furthermore been conjectured that it is the norm for such black holes to sit at the midpoint of every outsize galaxy. Data has revealed, however, that […]

The latest survey shows that the number of people believing that some extraterrestrial beings are behind these sightings has increased as compared to the […]
Elevating Space Access: The Reality of Space Elevators
Introduction to Space Elevators Definition and Concept A space elevator, also known as a space bridge, star ladder, or orbital lift, is a proposed type of planet-to-space transportation system. The primary component of a space elevator is a cable, or tether, anchored to the Earth’s surface near the equator and extending into space. The other […]
UFOs regularly spotted in restricted U.S. airspace
For those interested in everything related to sightings of unidentified flying objects, this summer started with a spectacular admission. American government acknowledged, albeit reluctantly, that it recorded over 140 sightings of objects in the sky, and that almost all of them are unexplained. Many of these incidents happened in the aerospace that is restricted by […]
The Big Bang Theory: The Dawn of the Cosmos
Introduction to the Big Bang Theory Overview of the Big Bang Theory The Big Bang Theory is the prevailing cosmological model that describes the early development of the Universe. According to this theory, the Universe began as an extremely hot and dense point approximately 13.8 billion years ago and has been expanding ever since. This […]
Earth’s first puff of oxygen may be thanks to volcanoes
We take the existence of oxygen on our planet for granted, but early in its days, Earth did not have much of it. There was a spike in amount of oxygen available at some point, and this burst of oxygen has been puzzling for the scientific community. We found evidence of it in Australian shale. […]
Cool Places We Could Migrate to Beyond Earth
We know that our planet will not last forever, and this is not a secret. We depend on the energy from the sun, and it is slowly decreasing. Although the necessity to leave the planet is highly unlikely to materialize in our lifetime, it is interesting to consider the options in this scenario. Venus comes […]
Beyond Roswell: Unveiling the Truth Behind Government UFO Secrecy
Introduction Setting the Stage: The Roswell Incident In the annals of UFO lore, few events have captured the public imagination as profoundly as the Roswell Incident of 1947. It all began when a mysterious object crashed on a ranch near Roswell, New Mexico. Initial reports suggested the recovery of a “flying disc,” but the U.S. […]
