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.

what will happen ?? If Black Hole comes in place of Sun ??

what will happen ??  If Black Hole comes in place of Sun ??

 "Nearly 500cr years, the sun will almost exhaust its hydrogen fuel"

 

 Hello friends, today we are going to talk about space, black hole, sun.

 We all know that our Galaxy keeps changing over time, like when you look at the solar system, it was like this before or not and it will be so later, it will also change with time.  It will be that the sun will lose its mass of 40,00,000 lakh tons every second and by the time you are reading these blogs, the sun will become 2.4 billion tons lighter by that time !!  And about 500cr years from now, the sun will finish all its hydrogen fuel and many stars will be destroyed in the universe like this sun.

 And you all know that when all the stars are over, then all the stars will go into the black hole, you are thinking this right?  That all the stars will merge in the planet black hole

 But nothing like this will happen, you will get an answer by the end of this blog.  We all know that the entire galaxy is the lowest qualifying place for humans to live, but you will have a question that

 Can you imagine life around the black hole?

 

 We all know from childhood that nothing survives from the black hole, but it also swallows the rays of light and at the same time swallows all the things of the galaxy.  Can you imagine ??

 But this idea of ​​yours will also change after reading this blog, it will change till date what we have been taught and after reading this blog you will get to learn something new about blackhole.  From the beginning of 1980 till today, probably all physicists or scientists believe that every galaxy must have at least one super massive black hole and a disk of gas and dust in it.

 

 And this black hole removes a large amount of Radiation and around it becomes a huge gera which is also called dead zone but you do not understand the meaning of dead horizon. Event Horizon means  It is where Sima reaches the gravity of the Blackhole and Dead jone  means that the zone where the black hole radiation reaches

 Now you must also be thinking that life can be imagined in such a way around Blackhole ??

 But the black hole is the least adaptable place in the universe, but it is not at all

 A recent research has shown that life around the black hole can be predicted.

 There is a very big scientist from Howard  University, Manas v lingam who thinks that Black Hole should not only be negative, we can also take it positively. He has said in his research that in the 1980s, A Blackhole dead jone are considered as small.  Many super short black holes were estimated to have a hair spread of up to 3200 light-year. But it was found by research that these designs have spread only from 40 to 100 light-year.

 You must have felt like hearing dead jone name, it would have ended in it, but it is not like that at all.

 If there is a planate in this dead zone, then the environment will be safe and in such a way, life on that planet can be imagined. Manas v lingam says that Blackhole is not just made for swallowing the things of Galaxy but it is for life.  Will create many elements.  The radiation that reaches the Black Hole dead jones does not change the environment of the planet, but produces elements for life such as proteins, lipids, DNA, and it is all that is necessary for life and all things prove it  It happens that blackhole is not what we think but it creates many elements that make life.

 But there is a condition that all planate distances should be within the defined habitable zone.

 This will create a very good environment around the blackhole and life can start in it, and now we must be thinking that life will start around the blackhole

 What would be the atmosphere like?

What will happen if someone goes into the blackhole??

What will happen if someone goes into the blackhole??

 Hello friends, today we are talking about blackhole.

 I am going to talk.

 You also know that if anything goes in the blackhole, it does not come back.

 But have you thought that what would happen to the thing that went inside the blackhole??

 So let's know about blackhole

 But before that we understand one question.

 What would happen if a person falls inside a blackhole or gets pulled into it due to strong gravity??

 So let's understand the answer of this question.

 "If a person falls into a blackhole due to strong gravity, then first of all that person will go round and round in the blackhole, that is, that person will go inside like a spring and it will become strong. Now this happens because when someone enters the blackhole  If a thing pulls, then whatever thing goes inside it, then a lot of gravitational force will be felt on the lower part of that thing and due to this, the same thing will happen to the human being and that human being.

 Will also be pulled into the blackhole in the same way.

 Slowly the body of that person will move on the boundary of the blackhole, but at the same time the movement will slow down from fast and it will stop on the boundary line.

 And you must be thinking what will happen after this??

 But you should know that blackhole is such a place where time and space collabe, that is, time moves very slowly.  And if you want to know more about black hole then you have to know about hawking theory.

    

Look at the above photo carefully, this person is seen going into the blackhole, but when he goes inside it, his body will spin and strong gravity will apply to the lower part and because of that he will go inside faster.

 Now you must be thinking that what would happen when a person or anything went into a blackhole??

 Sir Stephen Hawking has taught us this very well that if a black hole observes anything inside itself, it all comes out in the form of radiation.

 We will understand this by giving an example.

 If you do not like a book or you are bored after reading it, then what happens to that book if you burn it????

 You can see that your book will be found in the form of ashes, but you will be thinking that all the knowledge in that book has been burnt?? So the answer is no.

 Because you still have the ashes of that book, even if you haven't read those words, they are still present in the ashes. Just like this, the same would happen in the blackhole as well, that according to Sir Stephen Hawking, the blackhole disappears in the end and it comes back in the form of radiation in the universe. Just use our website to know such secrets.
