The wormhole was first conceived by the famous scientist Albert Einstein. According to Einstein's famous field equation, gravity behaves like a kind of tunnel. And this tunnel is called a wormhole. It is very easy to reach from one point of space-time to another point through the wormhole. If we want to explain the wormhole more easily, we can call it a gravitational tunnel. The mysterious tunnel created by the effect of gravitational force in space can be called a wormhole.   ...

A kind of hypothetical radiation that is created from black holes. Radiation is created from the heat energy when the mass of an object is converted into heat energy. Famous physicist Stephen Hawking gives an idea about this radiation that is created from Black Hole.   Mathematically if we want to explain hawking radiation it's the temperature and mass of the blackhole they are proportional to each other. The meaning of this is that the amount of heat that will be generated in a black hole will be the opp...

    Dark Matter is still a hypothesis. Scientists have not yet fully observed Dark Matter. Dark matter never interacts with electromagnetic forces. Dark matter is completely invisible in ordinary light. In modern technology, it is impossible to detect dark matter. Some scientists believe that dark matter exists. Our entire universe is made up of 6% dark energy, 26% dark matter, and the remaining 5% normal matter. Dark matter and antimatter are not the same thing. We know that baryonic matter is made up of electrons, protons and neutrons. Most likely dark matter is composed of baryonic or non-baryonic matter. Most scientists believe that dark matter is made up of non-baryonic matter. If we do not see dark matter, how do we know that dark matter exists? Scientists have been able to determine the mass of large objects in space through research on their movements. Astronomers tested some spiral galaxies in the 1970s. They see that the stars in the center of the galaxy are moving m...

Sudipta Roy Ghosh Its really a matter to think about, teachers actually possess any right or not! And if so, what type of rights they are possessing.

People resort to tell lying things for so many different reasons that it' d be impossible to list them all. Most of the common motives for telling lies, avoiding punishment is the primary motives for both children & adults. Other typical reasons include protecting ourselves or other from harms, maintaining self privacy, and avoiding embarrassment to name a few.. Except the genetic hidden emotion people often tell lies.

After the research tube group of Dr. EKma got 9 motives for telling lies. These are : 1) Protect some one else from punishment. 2) Protect oneself fr...

  This is considered to be one of the toughest subjects in IGCSE but yet, it can be overcome with perseverance and hard work. First thing’s first: you should become an avid reader. When you read, notice the descriptive language, the imagery and the tone in your books. Using descriptive language in your writing can boost your marks. Practice writing essays. If you’re good in writing essays, you’ll become adept in Section B too. Remember, formats for Section B are extremely important and so is the point collection. The more relevant information you have collected from Section B, the better your marks will be. But of course, the arrangement of your writing is extremely important. You do not want to lose any marks in Section A so make your answers concise; do not begin writing by repeating the question. They’ll often ask to pinpoint particular stuff so watch out for those. Usually, one or max three points will be enough. For the big comparative question, make sure you give sufficient q...
