The theory of relativity and what does E=Mc2 actually mean

Welcome friends, we all know that this world rests on some principles.Today we can see thousands of our friends who are away. We can talk to them. And within a few hours we can go from one country to another.If we want any information, then we can take ham immediately from mobile or computer.And by staying on the earth, we can easily learn about the other planets that are thousands of light years away from the earth.

  

We all know that before the start of the science era, if there was a big event on holiday or on earth, then everybody considered it as the wrath of God. Nobody wanted to know how all this happened.If a meteor had fallen on the earth before the beginning of the science era, everyone was angry at God before us and because of that, they had done all these things.But when the science era came into existence, then those questions came to be resolved. And everyone came out of such a dark life and started understanding science.

And all this has been successful due to the hard work of science and scientist. They have answered all our complicated questions.

Today we are going to talk about Einstein's very useful Theory of Relativity in this blog. If you are interested in a topic like Physics, then read it fully and share it to your friends.

             The Theory Of Relativity 

So let's talk about the theory of relativity.

We all know that the Theory of Relativity was discovered by the great scientist Sir Albert Einstein, that's why we also call the Theory of Relativity as Einstein Theory of Relativity.Einstein gave the Theory of Relativity twice.

Because when he gave the first theory, he was not completely satisfied with his first theory, which is why he later gave the second theory of relativity to the world.

Einstein has divided it into two parts. 

(1) Special Theory of Relativity

(2) General Theory of Rela

(1) special theory of relativity 

Einstein says that there are two types of frames of reference in this world.

(1) inercial frame of reference 
(2) non inercial reference 

[1] Inercial frame of reference means 

any object, or body, if it is traveling at the same fixed speed, under which circumstances it is a speed constant, then it is called inercial frame of reference. 

[2] None inercial frame of reference  means

None inercial frame of reference means that in which the speed of the car is not constant.

For example, any car on the way. 

When there is any obstacle in the way of the car, if the speed of the car has to be reduced and at the same time the speed of which body has to work or more. It is called none inercial frame of reference.

We all know that the Special Theory of Relativity is valid for inercial frame of reference. Now know that both speed and time are not absolute.

 Time 

Learn about how it is relative.Suppose you are sitting in a car on the way from a speed of 60km / hr. And with you your friends are also sitting in the car with you. So according to you three people, your speed will be 0 (zero) according to each other.

But suppose a ladys is standing on the side of the road. According to that your speed will be 60km / hr. 

But now suppose if an car is coming towards you. And his speed is also 60km / hr.But because your speed is also 60km / hr, you will find the front car sitting in the car coming towards you at a speed of 120km / hr. 

So this shows that the speed is relative.Character changing only the speed difference is coming.

Now know that time how the relative is..

By the end of the century of 1800, the Michelson Morley Experiment had proved that the speed of light was fixed.It never changes under any circumstances. 

 

light of sun 

But it is also certain that light travels the fastest in the entire universe. No object can move faster than the speed of light.

But if this is true, then suppose a vehicle is moving faster than the speed of light at leisure. On that vehicle there is a light in front of it.So in this condition, if we calculate the speed of that vehicle by mixing the speed of this light, then it will be twice the speed of light.

So this equation is not broken, that's why time starts flowing slowly for the people sitting in that vehicle.

This means that Einstein had said that one year of that vehicle can be as many as thousands of years on Earth.

Now let's talk about Einstein second theory of relativity.And Einstein named this second theory the General Theory of Relativity.

(2) General Theory of Relativity.

Now let's talk about General Theory of Relativity. Einstein was not completely satisfied with his special theory of relativeness. That is why he discovered General Theory of Relativity.

Einstein wanted to know what is the effect of gravity on time.He had also proved under an experiment that gravity is only excelaration.

But Newton said that if anything comes towards the ground, then it goes down due to gravity. That is why Newton believed that the Earth's rotation is due to the gravity of the sun.

One gravitational body affects another gravitational body. And pulls it towards him. 

Einstein's General Theory of Relativity proved Newton wrong, saying that the Earth does not rotate due to gravity of the Sun.But due to the band of space time due to gravity, it is applied.And all the other planets revolve around the sun because of this.

Einstein first laid the foundation for space time theory under which he said that gravity affects time. Meaning for any object which has gravity, time will slow down, just time in space will go fast.
So gravity creates a kind of weight in space and that is why it rotates around any body of high weight.

Everyone believe that light moves only in a straight direction  

But Einstein did the star's real position which was very different from before.And that is why we see stars in different positions than their real positions.You may also think that it was good that Einstein would not have told us that light is not just in a straight line but light is also twisted. If we had not told, we would have remained unaware of it for a long time.

After proving all this, he gave the world

the most powerful, most important equation E = Mc2.
In which E means energy, M means mass, and C means velocity.

So friends, this was the theory of relativity. I hope you have understood about this in a much better way.

Einstein says.                                                       

               physics is not vocation 

                     But physics is everything.
