What does Imaginary Time mean?

Imaginary time is not like the Real-time we experience in our day to day life which is classified as past, present and future. It is a very bizarre idea introduced by Stephen W.Hawking.

Imaginary time is right angled to real time. It was introduced to eliminate the theory of Creator of God from the Universe.Related image   

It is used to remove singularities which avoid the laws of physics to break. It can be seen in MINKOWSKI SPACE-TIME model which was adopted by the theory of relativity.

Real-time has a beginning which is called a big bang and an end which is called a big crunch. But Imaginary time has no beginning and no end rather it has a closed surface like a sphere. We do not have a start and end for a sphere.Related image

The imaginary time direction could be from the south pole. As one goes towards the north from the south pole, the latitudes which are uniformly placed inflates and reach the maximum at the equator and again contract to a single point at the North pole. Even though the universe is zero at the poles it would not be a singularity. This helps us to understand the origin of the universe in the imaginary time can be at a random regular point on the spacetime.

We now consider Imaginary time as a new dimension added to the regular time.

Stephen Hawking popularised this concept in his famous book " The Brief History of Time".Related image

He personally thinks that individual particles can travel through imaginary time and arrive back at an earlier real-time but not that people can travel back in time like in films such as Back to the Future.

Do you agree with him?
Do you think time travel is possible?

All of physics is either impossible or trivial. It is impossible until you understand it, and then it becomes trivial.

What is the most easiest way to understand the interaction of subatomic particles?

The easiest way to represent and understand the interaction of subatomic particles is by using Feynman Diagrams. In theoretical physics, this method is used as a pictorial representation of the mathematical expressions of the behaviour of subatomic particles. This method was given by one of the famous scientist and lecturer  Richard Phillips  Feynman.   These diagrams are used to calculate the most difficult equations using diagrams. For example collision of two electrons: When two electrons collide they interact with each other and scatter apart. The interaction happens as follows: When two electrons are brought together they repel each other and move apart. This repulsion takes place due to the exchange of the gauge bosons. Gauge boson exchange is otherwise known as the exchange of particle or information. These are virtual particles. Here photons are the exchange particle involved. The photon released from one particle hits another electron and changes...

IS GRAVITATIONAL FORCE FICTITIOUS IN REALTY ?

Mr.Albert Einstein , one of the brilliant minds of the world, published the general theory of relativity in 1915. He gave a very different approach to the idea of gravity. The theory says that there is no such thing as gravitational force. Yes, the theory really proposed it. Then what causes this attraction? Its the metric of the space around it. The change in metric causes the objects to fall towards the heavier object. Here metric describes how an object moves in the space. The analogy is the space-time wrap is assumed to be a stiff cloth and the mass as balls. Now if we place the heavier ball, the cloth bends down due to its mass. If we leave a lighter ball into the cloth, the ball starts to orbit around the heavier massed ball as shown in the image below.     So when you drop something it doesn't fall due to any force of attraction but due to its natural motion of accelerating downwards towards the centre of the curved space-time of the E...

CHARACTERISTICS OF LASER

LASERs play a very vital role in many fields and industries. What makes it so special? It's characteristics. Lasers have: 1.High directionality 2.High monochromaticity 3.A high degree of coherence 4.High brightness So let's understand each one in detail. 1. High directionality: The lasers are made of active medium placed in between two reflecting resonator mirrors one which can partially reflect and the other which can fully reflect the light. Any photon travelling in a direction away from the cavity axis reflects away by the mirrors within a few reflections and is thus not allowed to propagate further, thus the beam drawn from the output mirror is highly parallel and directional. The degree of directionality is expressed as the divergence .  Minimum spot point:  The curvature of the mirror confines the light within the cavity and causes the beam to narrow down to a radius w o    and this is called a minimum spot point. The ...
