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...

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 +(-1000) and so on. So, this equation 1+(-1)=0 is the key to understand how our universe began. Total energy of the universe =0. However, at the beginning of the universe, the 0 spontaneously divided into two parts. One into millions of trillions of mega watts of energy and other one into negative millions of trillions of mega watts of energy. The total energy of the universe was still zero but it was divided into 2 huge numbers. The positive energy today is represented by all the matter that we can see in the universe in form of stars, planets, radiations and particles. And because energy is equivalent to mass (using Einstein's famous equation E = mc2), so the positive energy of the universe is represented by all the mass that we can see. Now coming to the negative part of the energy: the negative energy is in the form of Gravity. The universe is Flat which means it is in perfect balance. Total energy of the universe is zero. The negative energy (Gravity) perfectly cancels out the energy of matter.

    This is a long discussion. Will share an article soon on this too IA.

    What is your basis to say that the negative energy is gravity?

    How it can be justified that gravity is the negative energy

    Inflation theory jus says that there was a vaccum energy in early universe, it doesn't say anything about negative energy, that undergo exponential expansion.

      According to Newton, objects fall because they are pulled by Earth's gravity/force. Whereas on contrary Einstein said that these objects do not fall. Rather these objects and Earth just freely move in a curved spacetime and this curvature is formed by mass and energy of these objects

Marie Curie the Scientist - History, Nobel Prizes, Achievements & Facts

History of Marie Curie      Polish-French Physicist Maria Salomea Sklodowska commonly known by French version of her name “Marie Curie ” was a Polish (Poland was part of Russian Empire at that time) by birth. She was born into the family of a secondary-school teacher on November 7, 1867 in Warsaw, Poland. After completing her early education in Warsaw, she relocated to France (Paris) in 1891 to continue her studies at the Sarbonne      She earned Licentiateships (at Sarbonne) in Physics and Mathematics . In 1894, she met her future life partner, Pierre Currie, a Professor in the School of Physics. She later married Pierre in 1895 and completed her degree as a Doctor of Science in 1903. Her husband Pierre Curie died in a tragic incident (caused by a street accident). Marie joined the University as a Professor of Physics. Marie Curie’s 1 st Nobel Prize – Physics Nobel prize winner 1903      Marie Curie won her first noble prize for her ...

String Theory

     String theory flips the page on the classical description of our universe by replacing all matter and force particles with just 1 element; Tiny vibrating strings that twist and turn in complex ways that, from our view point, look like particles. To simply understand about String Theory, Imagine you have a beautiful tree that is full of Oranges and you ask yourself what is the Orange formed of. How do you answer that question. Well you  wanna look deeply inside the Orange so you’ll magnify it and magnify it again and again and will keep on doing it. Deep inside sooner or later, you’ll begin to see that molecules are not the end of the story. Because you can emerge them (the molecules).  And if you make them big enough deep inside, you’ll begin to see atoms. Atoms are not the end of the story too because, we have electrons. Zooming in around the nucleus, deep inside (mostly empty space in the atom) but deep inside we see the nucleus. So if you grab t...

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...
