The universe as we know it has a beginning, but what about its end? Theories of the death of the universe have been proposed by scientists and philosophers alike, each with their own unique perspective on the ultimate fate of the cosmos. In this blog post, we will explore some of the most popular theories of the death of the universe. The Cold and Dark Universe ❄️ One of the most common theories of the death of the universe is called the heat death hypothesis. It says that the universe will eventually run out of energy and become a cold and dark place. This is because everything in the universe tends to get more chaotic over time, according to a rule called the second law of thermodynamics. The heat death hypothesis says that one day, everything in the universe will be so spread out and disorganized that there will be no more energy left to do anything. This means that there will be no more stars, planets, or life in the universe. The Torn Apart Universe 💥 Another theory of the death ...
In 2016, astronomers discovered a small asteroid that has been dubbed as Earth's second moon. The asteroid, named Kamo' oalewa, measures less than 50 meters across and circles the Earth in a repeating corkscrew-like trajectory that brings it no closer than 40 to 100 times the distance between the Earth and the Moon. Although Kamo' oalewa is not a conventional moon, it is considered a quasi-moon or a "constant companion" of Earth. Kamo' oalewa is not the first asteroid to be considered as Earth's second moon. In 1986, an asteroid named 3753 Cruithne was once nicknamed "Earth's second moon" after its discovery. However, it turned out that it actually orbits the Sun, being a case of a co-orbital asteroid. The discovery of Kamo' oalewa has sparked interest in the scientific community, as it provides an opportunity to study the dynamics of quasi-satellites and the gravitational forces that shape their orbits. According to a new study in Natu...
NASA's James Webb Telescope set to launch in 2019 is the most powerful telescope ever made in the history of space exploration.It is believed to be the successor of the Hubble Space Telescope. But there's more...NASA calls James Webb telescope as a time machine! The James Webb telescope could see as far as 13.5 billion lightyears away.That is,it can see back 13.5 billion years back in time.It could see the formation of the first stars and galaxies in the universe after the big bang! The James Webb telescope could tell us more about the atmosphere of exoplanets,and maybe help us find life in other planets.The Trappist-1 planets would be the primary goal. JWST(James Webb Space Telescope) will see the universe in light invisible to human eyes. Though it seems primarily infrared light, it can also see red and gold visible light.
