Discover the Mysteries & Secrets of Universe
Cosmos, in general, relates to the structure and nature of the universe, and the nature of “the universe” relates to human systems of seeing, our ways of thinking and perception, and what can be seen, literally and figuratively, by humans in general. It is not only about the cosmos, it is about who we are and where we are going as a species.
Professor Lawrence Krauss has a talent for explaining complex ideas in simple language and communicating his enthusiasm for his subject to the reader. Starting with a funny story in which the horse is reduced to a sphere for simplicity, he quickly turns to talk about quantum mechanics and the theory of relativity, explains why dinosaurs […]

For the first time, the idea that the Earth revolves around the Sun arose in the minds of ancient Greek scientists. The founding father of heliocentrism is considered to be Aristarchus of Samos, who was born around 310 BC. How well he managed to work out his hypothesis is not known for certain, all information

“Past the point of no return”. It is possible that on long-duration flights, like a mission to Mars for example, an astronaut’s body might reach a point beyond which bone loss or muscle atrophy is permanent despite having Astronauts Training. Such damage wouldn’t prevent the return trip home itself, but it would greatly reduce their
What happened at Roswell- Everything about Roswell UFO incident Where is Roswell? Roswell is a city in Chaves County, New Mexico. At the 2010 census it had a population of 48,366 inhabitants and a population density of 624.22 people per km2. “Roswell” is popularly known for the 1947 Roswell incident. The investigation and recovery of
Gauss’s Law Understanding Gauss’s law is a bit different from understanding the electric field. In both cases, you need to know how to calculate the total electric field in a closed system in an electric field. But in the electric field case, you do that by knowing the total charge in the system. In the

Our natural satellite, the Moon, has been attracting people’s views for more than one millennium. It is the second brightest object in the sky after the Sun and in many ways has an impact on earthly life, for example, it is thanks to the Moon that there are ebb and flow. The distance to the

The mathematical and philosophical basis for current elementary particle physics is Quantum Field Theory (QFT). Other branches of theoretical physics, such as condensed matter physics and statistical mechanics, use it as well. In a nutshell, QFT is the application of quantum mechanics (QM), which deals with particles, structures, or devices of an infinite number of

The special theory of Relativity First, there are no “privileged” points of reference in the real universe. The rules of physics are the same for all as long as an object moves along a straight line at a constant speed (that is, without acceleration). It is kind of like looking out a train window and
Space travel looks fascinating however, it affects the health of a person or Astronauts both Mentally and Physically. Let’s look at some of the Major Health problems in Space Cardiovascular Deconditioning Microgravity exposure degrades the cardiovascular system’s general condition (heart and blood vessels) and specifically degrades orthostatic tolerance (the ability of the cardiovascular system to
