4 improbable things that the laws of physics can enable Einstein's general theory of relativity is known for predicting wormholes, which are time-traveling shortcuts that link various regions of space and time. Nobody has ever seen one, and whether you could fly down one even if they did exist is a point of contention. As we wait for a visitor from the future to inform us, consider the following physical impossibilities. MATTER MARRIED WITH ANTI-MATTER Normally, when matter collides with its antimatter counterpart, both “annihilate” in a burst of energy. It's just as well that we exist in a world of so much matter and so little antimatter. Strangely enough, certain matter can even be antimatter. Majorana fermions will be their own antiparticles, capable of annihilating themselves in the right circumstances. Physicists have long speculated that neutrinos fit into this category, but demonstrating it would require observing some of the universe's rarest processes in motion, ...

Quantum Wells,and Examples or application of Quantum Wells.
Quantum Wells,and Examples or application of Quantum Wells. The classic model used to demonstrate a quantum well is to confine particles, which were initially free to move in three dimensions, to two dimensions, by forcing them to occupy a planar region. The effects of quantam confinment take place when the quantum well thickness becomes comparable to the de Broglie wavelength of the carriers (generally electrons and holes ), leading to energy levels called "energy subbands", i.e., the carriers can only have discrete energy values. A wide variety of electronic quantum well devices have been developed based on the theory of quantum well systems. These devices have found applications in lasers, photodetectors, modulators, and switches for example. Compared to conventional devices, quantum well devices are much faster and operate much more economically and are a point of incredible importance to the technological an...
Why did Albert Einstein have so much difficulty accepting Quantum Mechanics?
Why did Albert Einstein have so much difficulty accepting Quantum Mechanics? Albert Einstein one of the most famous physicist in the world and very much popular for mass-energy equivalence that is E = mc 2 Then Why did Albert Einstein have so much difficulty accepting Quantum Mechanics? Quantum Mechanics is very vast subject to study and is very difficult to understand but in short we can conclude that Quantum Mechanics implies that a particle such as ELECTRON can pass through TWO HOLES AT ONE TIME READ ABOUT TOP 10 SOLAR PROJECTS OF INDIA His analysis of the "spookiness" of quantum mechanics opened up a whole range of applications including quantum teleportation and quantum cryptography, but he wasn't completely convinced by the theory of quantum mechanics Рand that story is as fascinating as the theory he attempted to nail down. German physicist Erwin Schr̦dinger's equations proved that a cat could end up in a peculiar sort of quantum state, being neither dea...
Why do solar eclipses look like a black hole in the sky?
Why do solar eclipses look like a black hole in the sky? What is meant by Eclipse Any solid object in our solar system can cast a shadow by blocking the light by the region behind it. This shadow in the space becomes apparent whenever another object moves into it. In general an eclipse occurs whenever either part of Earth or Moon enters the shadow of other. What is meant by solar eclipse When the Moon’s shadow strikes Earth, people within that shadow see the Sun at least partially covered by the Moon; that is, they witness a solar eclipse . What is meant by Lunar Eclipse Lunar eclipses occur when Earth's shadow blocks the sun's light, which otherwise reflects off the moon . There are three types total, partial and penumbral with the most dramatic being a total lunar eclipse , in which Earth's shadow completely covers the moon . black holes and types of black holes This means the Moon and the Sun appear exactly...
what is the Science of a on grid solar
what is the Science of a on grid solar ? First of all what is solar and what is solar energy Solar energy a great source of energy and a perfect alternative for Coal and other source of energy. So what are the advantages of solar energy and how we can utilize the solar energy and related all questions are answered here India is endowed with vast solar energy potential. About 5,000 trillion kWh per year energy is incident over India's land area with most parts receiving 4-7 kWh per sq. m per day. Solar photovoltaics power can effectively be harnessed providing huge scalability in India. what is meant by Electrical Grid An electrical grid , electric grid or power grid , is an interconnected network for delivering electricity from producers to consumers. It consists of: generating stations that produce electric power . electrical substations for stepping electrical voltage up for transmission...
What will happen if a man will fall in the black hole at the middle of our Milky Way galaxy?
What will happen if a man will fall in the black hole at the middle of our Milky Way galaxy? Let us consider first what is black hole Black holes are some of the strangest and most fascinating objects in outer space. They're extremely dense, with such strong gravitational attraction that even light cannot escape their grasp if it comes near enough. There are three types of black holes that known to scientist so far 1.Stellar black holes 2.Supermassive black holes 3.Intermidiate black holes out of these three black holes the supermassive Black Hole is present at the middle of each galaxy including ours the MILKY WAY GALAXY WHAT IS SUPERMASSIVE BLACK HOLE Supermassive black holes are consider as the birth of Giants. As the name suggest supermassive black holes these are millions or even billions times as massive as the sun, but they are same in the diameter. Such type of black holes are considered to found in the center of every galax...
what is the role of chlorophyll in the preparation of food in plants ? what is photosynthesis ?
what is photosynthesis ? what is the role of chlorophyll in the preparation of food in plants ? what is meant by chlorophyll ? A green pigment , present in all green plants and in cyanobacteria, which is responsible for the absorption of light to provide energy for photosynthesis. Chlorophyll is located in a plant’s chloroplast s, which are tiny structures in a plant’s cells. This is where photosynthesis takes place. Phytoplankton, the microscopic floating plants that form the basis of the entire marine food web, contain chlorophyll, which is why high phytoplankton concentrations can make water look green. CLICK HERE Green plants have the ability to make their own food. They do this through a process called photosynthesis which uses a green pigment called chlorophyll . A pigment is a molecule that has a particular color and can absorb light at different wavelengths, depending on the color. There are many different types of pigments in nature, but chlorophy...
