What is time dilation??

 Time dilation.

Generally people think that time is same for  all .the man sitting in home and watching TV and the man whose traveling in train..the time between these two people are different...and also there is time difference in 30th floor and ground floor of building (this difference is in micro seconds ..so we unable identify time difference...)

In this article we try to know ..

What meant by gravity..??

How gravity exists..??

What is special theory of relativity...??

How speed and gravity effect's on time..??

What is space time..??

At beginning Newton introduced some theory's about the universe they are..

*Universe follow same and constant time..

*The universe is in three dimensional shape..

And so on...but there are some mistakes in the theory's..

In 1905 Einstein introduced special theory of relativity this theory changed hole scientific world and in view of perspective of science..

*The time is different in different places .

*Only light speed Is constant ..in all the time..

*There is no object that travel with equal speed of light ..because ,light do not have any mass..by considering light speed Einstein reveled some unbelievable theory's..

This universe is filled with space time this  is like fabric ..and it have  4 dimensions  ...

The space  time is formed due to the big-bang...

To understand space time ..considar a cloth which is sorrunded by a ring as shown in figure .place a object in the middle ..and throw some stone's inside of fabric ..we can observe the stones surround that object ..after some time stones meet the object at the centre of fabric..

Which create higher slop in space time ,then it have strong magnetic force or field..so it able to pull surrounding objects inside of it ...for example consider our solar system .

the sun have strong magnetic field because of this planets revolve around the sun ,but here one question raises..if the sun have strong magnetic field then why planet's do not fell inside the sun...?? because planet's revolve with heigh and  constant speed due to this plants cannot deviate from the orbit...

Similar star's and galaxies have very higher mass so they create more slope in space time ..

Time 

In olden days people thought  that time is constant in everywhere ...but enstin proven it is wrong ..he said time is different in different places ..

Generally two factors influence on time ..

1) speed and gravity ..

Let's see how speed effects on time ..

Assume there  are two person's person A,person B ..person A he is sitting at home ..person b  traveling in a plane ..comparing time difference between two person's..the person B time duration is less ..

For better understanding  assume another example..

Consider two square boxes ..inside the squres

 

 box there is lighter ball moving up and down direction ..one bounce Is equal to 1 second ... If one of the box taking to a distance with some speed then it is look like this ...

The second box time will be less, comparing to first box. here the light ball speed same but the distances increses ...same like when we try to reach the speed of light the becomes slower and slower.. scientists came to knoe conducting an experiment ..they put atomic clock on erath and in a plane the time in two atomic clocks are not same...the time in international space station and on earth are not same...

Let's see how gravity effects on time..

Simply we can say where there is more gravity then there is decrease in time .. similarly where there is less gravity then increases in time..black Holes have very high gravity so it pull light in side of it ..but we still didn't know what happen inside the black hole ..time get frezzed when we try to reach near to the black hole.. because of time dilation the GPS satellites shows 10 km difference..the worlsds greatest scientist Albert Einstein ..he proposed various theories by just imagination..like Quantum theory ,string theory, general relativity...etc
