Global Climate Change

Climate change is the change in average patterns of natural events or phenomena such as temperature and rainfall over time in a region or around the world. Changes may occur naturally as well as occur due to human activities posing threats to nature. How Climate Change Occur / Causes of Climate Change There has been a drastic increase in climate change since the industrial revolution around the globe. Greenhouse gases are the primary cause behind these climatic changes. These gases trap and hold light energy reaching the earth’s surface from the sun, and radiate it in the form of infrared heat. Eventually, this process causes an increase in the average temperature of the atmosphere of our globe. Carbon dioxide (CO2), methane (CH4), nitrogen oxide (N2O), and chlorofluorocarbons (CFCs) are major greenhouse gas contributors.  Carbon DiOxide (CO 2 ) .  CO2 is generated due to natural processes (i.e. volcanic eruptions) as well as through human activities (deforestation and burning of fossi

How Sun Works: Quantum Tunneling

Do you know if the Sun was fueled by Gasoline or wood, it would have been burnt out in just a few hundred years, So how it is still here after 4.5 billion years.... Physics!!! The Sun is like a big nuclear reactor in the sky. It is fueled by nuclear reactions that fuse Hydrogen atoms into Helium, other heavier elements and energy (in the form of Photons) in the process. In this way the Sun is slowly converted into mass and energy in the form of sunlight and have more than enough fuel for us for billions of years. But nuclear fusion is not as simple as it looks. Fusion is the process that powers the Sun and the stars. It is the reaction, in which two atoms of Hydrogen fuse together to form an atom of Helium. In the process some part of hydrogen is converted into energy. On earth we need to heat hydrogen hundred times hotter than that of the Sun to set a fusion reaction. Sun has a temperature of 15 million Celsius degrees in its core whereas it requires more than 100 million Celsius deg

Did Universe Popped out of NOTHING

 If we succeed in getting rid of everything from a part of space i.e. from all the planets, stars, atoms, particles, even light and radiation etc, this space still have weight. It turns out that NOTHING is not nothing but it is something. How is that possible? Space is bubbling with virtual particles that pop in and out of existence. These particles do this in such a short time scale so the laws of classical Physics forgives the creation of these ghost particles which seem to come out of nothing. The laws of Quantum Mechanics allow this.  To visualize, consider an empty space within a proton. Since most of our physical world is made up of protons and neutrons, this so called empty space (inside protons) gives mass of proton. "Empty space is actually full of quarks and Gluon Field Fluctuations, so empty space is not empty" (Professor Derek Leinweber, University of Adelaide).  Here is the simple visualization. 0 represents nothing. But 0 can also be expressed as 1+(-1) or 1000

Origin of Elliptical Orbits (Kepler's 1st Law)

In 1609, Astronomer Johannes Kepler published Astronomia Nova, a book containing 10 years of work to understand the orbit of Mars planet using his revolutionary observations from his mentor and employer Tycho Brahe who was famous for generating huge quantity of high quality data and he needed to find the best explanations for the motion of Mars.  There were three models of planetary motions at that time but not a single of them worked well. First one was the Ptolemy System (presented bt Claudius Ptolemy) that puts the Earth at the center and all the other planets of our solar system and the Sun orbiting around the Earth in perfect circular paths so the Ptolemy system was an earth-centric system which suggested that the seemingly improper paths of the Sun, Moon, and planets were actually a combination of some proper circular motions seen in perspective from a stationary Earth. The second model was the Copernicus 's heliocentric model . According to this model, Earth was placed amo
