### What is Tachyon (Tachyon Particle) | Tachyon Particles that Travel Faster than the Speed of Light !!!

A Tachyon is a hypothetical particle, that always travels faster than light. It is also known as Tachyonic Particle.
The possibility of particles moving faster than light was first proposed by Robert Ehrilch and Arnold Sommerfeld, independently of each other.
This term comes from greek word  'tachy', that means 'rapid'.
Two complementary particle types that are known to exist are called - Luxons and Bradyons.
Luxons are the particles that always move at the speed of light and Bradyons are the particles which always move slower than light.
Here we are talking about tachyons, also called as tachyonic particles, that always move faster than light.

## What is Tachyon Video

Now let me tell you one very interesting thing about tachyons...
The mass of tachyons is imaginary!!!
If you didn't get it let me explain it to you.
The mass of any object at rest is different from its mass when it moves. But we do not observe this difference in mass at speeds much lesser than the speed of light.
But when the speed of the object is comparable to the speed of light then we cannot neglect this change in mass at this high speed.
As we are talking about tachyons, that always have speed higher than the speed of light, we have to consider this change, in mass.
So for such fast moving particles, the rest mass is different from the relativistic mass.
Here is the formula, that explains the relationship between the rest mass and the relativistic mass.

mr = m0/sqrt(1-v2/c2)

Here Mr is the relativistic mass
m0 is the rest mass which is invariant mass
v is velocity of the object and
c Is the speed of light.

Now let's Focus on the formula,
As we know that the speed of tachyonic particles is always greater than the speed of light.
i.e. here in this case
v greater than c, so v/c greater than 1
also then v2/c2 would be greater than 1

Now on subtracting a number, which is larger than 1, from 1, we will get a negative number.
And we know that the square root of a negative number is not real. it is an imaginary number.

From the formula, if we assume that the rest mass of tachyons is imaginary, then we will have imaginary numbers in the numerator and also in the denominator of this formula. so this imaginary part will cancel out and we will have a real relativistic mass.
So from this discussion, we can say, that the mass of tachyons will exist only when they will travel faster than light.

Unlike ordinary particles, the energy of a tachyon decreases as its speed increases.
Note that, this is just opposite to the ordinary particles where increase in speed results in increased energy.
As the ordinary particles, cannot travel faster than light, in the same way, tachyons are forbidden from slowing down to below the speed of light. Because infinite energy is required to reach the barrier from either above or below.
You will be surprised to know, that tachyons can be used to time travel!!! A tachyonic antitelephone is a hypothetical device in theoretical physics, that could be used to send signals into one's own past.

### Alcubierre Warp Drive | Alcubierre Drive | Warp Drive | Travel Faster than Light

There are various ways like teleportation, wormholes and warp drive, that can be used to travel at very high speed, even  faster than the speed of light. Here I will discuss the concept of warp drive. The idea of warp drive is highly fascinating which is based on distorting the fabric of space and time to achieve a speed many times more than that of the light.
According to scientists, it is possible to travel faster than light With the help of Alcubierre warp drive.

## Alcubierre Warp Drive Video

The Alcubierre warp drive was proposed by Mexican theoretical physicist Miguel Alcubierre and is based on a solution of Einstein's field equations in general relativity.
But how is it possible and what are the requirements for warp drive? Since we know any object having mass, cannot travel faster than light as it will go against the laws of Physics. Since to achieve this speed infinite energy is required, which is practically not possible. Then how it is possible with warp drive to travel faster than the speed of light?
Actually in warp drive a spacecraft does not have to travel faster than light within a local reference frame. The spacecraft would traverse distances by contracting space in front of it and expanding the space behind it. This mechanism results in effective faster-than-light travel. In this way The Alcubierre warp drive shifts the space around an object.
So it's more like pulling the destination towards it while pushing its starting point back, instead of actually traveling faster than light.
This makes it possible for the object to reach to its destination faster than light would in normal space. Therefore no laws of Physics are broken.
But now the basic problem is, how to contract and expand the space time fabric that is required for the warp drive.
So let's discuss how this can be done.
According to great physicist Albert Einstein, any object having mass can create curvature in space time fabric. In other words, it can contract the space. Larger the mass, more it can contract the space. But we need extremely large amount of mass, equivalent to the mass of a black hole to contract the space so that it can be used in warp drive practically.
So we need to construct an engine, powerful enough to control a small black hole. This engine can be placed in the front part of the spacecraft so that the Space in front of the spacecraft can be contracted.
As I have discussed earlier that for warp drive we need to contract the space in front of the spacecraft and expand the space behind the spacecraft. Now we know that we can use very large mass to contract the space. But we do not know how to expand the space.
But it is not impossible. As We know, our universe is expanding at an accelerating rate. According to scientists, dark energy and dark matter are considered responsible for this expansion. So one possible method to expand the space is using dark energy or dark matter for warp drive.
There is one more technique that we can use for the expansion of space. As I just told you that a normal mass i.e. positive mass can be used to contract the space. It Means, if we could find a negative mass, then it will do just opposite to it. So a negative mass would cause expansion of the space. We can use this system in the back side of the spacecraft, that will help in expanding the space that is present behind the spacecraft and hence warp drive will become possible.
There is one interesting theory, known as dark fluid theory. The dark fluid theory combines the concept of dark matter, dark energy and negative mass. If we could find the dark fluid somehow, the warp drive would become a reality and traveling faster than light would not be impossible.
So friends, How many of you think that warp drive is possible in future?

### Conservation of Angular Momentum | Conservation of Angular Momentum Experiment | Angular Momentum

Here you will understand the principle of Conservation of Angular Momentum. For explaining the conservation of angular momentum I have taken help of two experiments. According to the Law of Conservation of Angular Momentum under ideal conditions, the angular momentum of a rotating object remains constant.
Principle of Conservation of Angular Momentum is given as the product of moment of inertia (I) and the angular speed (w).

Angular momentum conservation formula -
Moment of Inertia (I) x Angular Speed (w) = Constant

Here is the first experiment to demonstrate the principle of conservation of angular momentum.
First climb on this Central circular platform and hold the handle. Now push the leg against the fixed outer platform to give yourself a spin.

## Conservation of Angular Momentum Video

Now observe carefully that, when you lean towards the handle the spin speed increases and on leaning outwards the spin speed decreases. Now repeat the same experiment several times and observe how the speed of rotation changes.
Now before explaining the science behind it let me show you one more experiments based on principle of conservation of angular momentum.
First sit on the chair and push the weights away at your full arm lengths and hold them.
Now take help of your friend and ask him or her to give you a turn gently.
Now observe that your speed of rotation increases as you bring both the weights close to you while rotating. And when you push away the weights the rotation speed decreases.
So these are the two experiments that explain the principle of conservation of angular momentum.
Now we will understand the Science that explains it.
According to the principle of conservation of angular momentum, the angular momentum of a rotating object remains constant under ideal conditions.
Angular momentum is given as the product of moment of inertia (I) and the angular speed (w).

Its given by the formula-
Iw = Constant

Moment of inertia is the product of the mass and square of its perpendicular distance from the axis of rotation.
So when the distance of the body decreases from the axis of rotation, its moment of inertia decreases but according to the principle of conservation of angular momentum, the product of moment of inertia and the angular speed must be constant. So to compensate for this decrease in moment of inertia, the angular speed of the body increases.
Just opposite of this happens when we move away from the axis of rotation. In this case the moment of inertia increases as the distance of the body increases from the axis of rotation. So to keep the product of moment of inertia and angular speed constant, according to the conservation of angular momentum, the speed of rotation decreases.
This same thing happens in the second experiment as the weights i.e. mass is pushed away from the axis of rotation, its moment of inertia increases so the angular speed is decreased and you spin slower. And opposite of it happens when the weights are pulled towards your body I.e. closer to the axis of rotation.
So friends, I hope now you understand the concept of principle of angular momentum conservation.

### Why Doctors Wear White Coat and Lawyers Wear Black Coat

You might have noticed that Doctors wear White Coat while Lawyers wear Black coat. First of all we will know why do doctors wear white coat. Actually white color is the symbol of health and hygiene. As we know that whenever there is a stain on the white clothes, it is easily visible. So when the white coat is dirty, doctors can easily feel the need to change or wash it. This frequent changing of cloths by doctors ensures that a clean, healthy and sterile environment in maintained in the hospital all the time. This is the reason why doctors wear white coat instead of other colored coats.
Now we will know why do lawyers wear black coat ? Wearing of black coats by lawyers and judges is part of the British tradition of the 17th century. Black color is considered as the symbol of honor, wisdom, dignity and justice. So black colored coat is prescribed for judges and lawyers, as they need to maintain all these values required by their profession.

## Why Doctors Wear White Coat and Lawyers Wear Black Coat Video

Friends now you know why people of different professions wear clothes of a particular color. A specific color is either required by a profession or tells something about that profession.
So friends, this is the reason why doctors wear white colored coat whereas lawyers wear black.
