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

Our Most Favourite Stephen Hawking's Famous Theory Regarding Black Holes Corroborated



Stephen Hawking once gave us the famous theorem regarding the Black Holes back in 1971 that has been proven right, using ripples in space time caused by the merging of two distant black holes. The theorem was derived from Einstein's theory of general relativity. The theorem states that "it is impossible for the surface area of a black hole to decrease over time". The theorem boosted interest of Physicists because it was closely related to another rule: The 2nd Law of Thermodynamics, which states that the entropy (disorder) of a closed system always increases.

Recent studies shows that the Physicists' confirmation of the area law seems to imply that the properties of black holes are significant clues to the hidden laws that govern the universe. 

A black hole's surface area can't be decreased, which is like the 2nd law of thermodynamics. It also have a conservation of mass as we can't reduce it's mass, so that's comparative to the conservation of energy.

A black hole's surface area is set out by a spherical boundary known as the event horizon (beyond this point nothing, not even light, can escape its powerful gravitation pull). According to Stephen Hawking's interpretation of general theory of relativity, as a black hole's surface area increases with its mass, and because no object thrown inside can exit, its surface area cannot decrease. But a black hole's surface area also shrinks the more it spins, so researchers wondered whether it would be possible to throw an object inside hard enough to make the black hole spin enough to decrease its area.

To test out this theory, the researchers analyzed gravitation waves, or ripples in the fabric of space-time, created 1.3+ billion years ago by two behemoth black holes as they spiraled toward each other at high speed. These were the first waves ever detected in 2015 by the Advanced Laser Interferometer Gravitational Wave Observatory (LIGO), a 1864 mile long laser beam capable of detecting the slightest distortions in space time by how they alter its path length.

By splitting the signal into two halves - before and after the black holes merged - the researchers calculated mass and the spin of both the original black holes and the new combined one. These numbers, in turn, allowed them to calculate the surface area of each black hole before and after the collision.



The surface area of the newly created black hole was greater that that of the initial two combined, confirming Hawking's area law with a more than 95% level of confidence. According to Physicists, their results are pretty much in line with what they expected to find. The theory of general relativity - where the area law came from - does a very effective job of describing black holes and other large scale objects.

The real mystery however, begins when we try to integrate general relativity - the rules of big objects - with quantum mechanics - those of the very small. Weird events start to take place, wreaking havoc on all of our hard and fast rules, and breaking the law completely.

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

Magnets and Magnetism - Interesting Magnet Facts for Kids

Historical Background of Magnets      Without the use of magnetism, we can’t even imagine the existence of light and there wouldn’t be most of the technology that we see today, use today, and utilize in our daily routine. The Greeks were the first to discover magnets. There was a village named Magnesia in an ancient Greek city in Ionia (we know this stone as Magnet today because of the village of "Magnesia"), where a shepherd found a magnetic stone (Lodestone) and observed the magnetism when nails from his shoes and metal pieces in his stick got attracted to the stone. People began to believe it was a healing element.      People used to use the stars and the sun to find their way around. But after the discovery of magnets, the Chinese were the first to use them as a tool for magnetic compasses. Magnets come in different sizes - as large as the earth and as small as the cell. Yes, you read it right. Our planet Earth is itself a big giant Magnet.  The history of magnets goes b

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
