Time Travel is practically proved

Time travel

    Time trave is the act of sending objects back in time to a few moments before the present, or sending

 objects into the future without the need for intervening time encounters from the present to

 synchronously  move between different locations in space with time-varying...

Scientists have proved this using some experiments. They have proved this before 50 years.

 Time Travel in Mythology

            Take the Hindu mythological story " Mahabharath," for example .A saint, such as  " Naradha,"

 embarks on a journey into space to meet "Lord Brahma." When I returned after seeing him, several

 years had passed. Similar stories can be found in Buddhism. Kumara Kasappa , Buddha's senior

 disciple, speculated that time operated differently beyond Earth, In the Japanese novel "Urashima

 Taro,"  a  character named Urashima-no-ko is a young fisherman who visits the king in a palace

 beneath the sea. After three days, he returns home. However, after 300 years, his entire village has been

 destroyed. Within three days, 300 years had passed.

During the first century BC, a character by the name of Honi ha  Magel, He was in a different universe

 and time when he awoke from sleep. Such time travel tales are prevalent in mythology all around the

 world. It's unclear when time travel first appeared in fiction. However, in 1640, "Supplement to the

 Journey to the West by Dong Yue" was published in China. It contains tales about miraculous mirrors

 and portals. It allowed for time travel.

Many of these time travel-related stories appeared in the 15th and 16th centuries.

In this tale from 1770, time travel is mentioned once more.

A dream if there ever was one: the year 2440.

The phrase "time machine" was originally used in the 1881 novel "The clock that went backwards."

The novel was the first to make time travel so well-known.

HG Wells' "The Time Machine" is set around 1885.

We have seen more about time travel in movies as well as in books.

Time Dilation Illustration

Now lets get back to the scientific aspects of time travel. What does time travel entail, exactly?

For that we need to know about time dilation.  Speed of light is constant.

Let's consider a hypothetical scenario. Inside a box with 2 mirrors on the top and bottom, light is

 travelling. The number of inside trips the light made in a single second. However, the distance that

 light travels in a second varies in space. It goes a lesser distance on Earth, but a longer distance in

 space. But we cannot assert that light moves quickly in space, as demonstrated by experiments like

 the Michelson-Morley, it is a constant. Light's speed is constant and cannot be changed. Therefore,

 time may be the root of this. Light moves more quickly in outer space because, Time moves more

 slowly in space., There has been time travel.

The faster you travel, slower you experience the time. Let me tell you my famous treadmill example,

You walk on the treadmill with the numbers 1,2,3 printed on it. Now after crossing the numbers 1,2,3,

 you make a jump.  But the belt in the treadmill is still running. And when you land back to the belt, it is

 number 7 and goes like 7,8,9.. This is time travel.

What happens here is, Earth is rotating at a speed in a particular time, and when you jump after 3 to

 space, there will be a separate time. In your point of view, time is normal, but when you land back you

 will continue from 7,8,9., The missed lines in between the jump of treadmill is the time travel.

You have time travelled from 3 to 7 in a forward direction. When you travel in a space ship you don't

 experience any change in time, but time runs faster in Earth. Time dilation affects your body

 biologically in terms of aging etc., You cannot believe what Einstein said theoretically, but it is true and

 a proven one. It was proven in the 1970s, 50 years back. Hafele–Keating experiment is a famous

 experiment to prove this time dilation.

The world's most precise timepieces are atomic clocks made of cesium. They have synced 3clocks with 

 two  on flights going east & west sides, then another clock is in the lab. All these 3 clocks are perfectly

 synced. Now after both flights have rotated Earth, all the 3 clocks are checked. There is a time

 difference among them in microseconds. So from this Einstein's time dilation theory was proven.

The clock that was carried on flight was also ticketed in the name of Mr. Clock. So time travel is a

 proven one on a micro level.

Russian Cosmonaut, Sergei  Krikalev  is the longest time travelled person, by being in space for 803

 days & going forward in the time of 0.02 seconds. There is a concept called "Twin Paradox". If there

 are 2 twins, with one travelling to space & other in Earth, When the space travelled guy comes back

 to Earth, then space traveled guy's age would be smaller than his twin brother in Earth. This is a very

 short duration, but it is a proven truth.

Time Travel Proven

According to time dilation concept, time is slower in more gravity area &  time is faster away from

 gravity. This was shown fictionally in the movie "Inception". The time of  1 hour in the planet near

 black hole is 7 years time on Earth. Because of more gravity, time is slower in that planet. Even though

 it is a science fiction, there is truth in it. Likewise, there is a time dilation between people living on

 Himalayas and sea level, that is the time of top people is 0.003 seconds faster than sea level people.

There is a time dilation between the top floor and ground floor people of 0.0001s.

Likewise, Our head is older than our feet. We can see this in our day to day gadgets we use.

 ie., the time in them. In older phones, we set time manually. But today, when we just switch on the

 data, time gets updated automatically. The reason for this is those 30 satellites that are revolving

 around Earth. These satellites maintain time accurately all over the world. These satellites are evolving

 at a speed of 14000km  /  hr at above 20000km height. The location of the user is also mapped by the

 position & speed of the satellite. But the difference of gravity between earth  & satellite,

this itself causes a time dilation. Each day there is a time difference of 38 microseconds between 

them. So, according to relativity theory, these time difference is adjusted daily. If it is not adjusted, it

 shows an error up o 10km distance variation in GPS. There are already bugs in Google maps,

if these time dilation errors are also added, then it will be a big chaos.

Particle Physics

                 In particle physics, time dilation is proved often. If we take Muon in its particle level,

if its normal life is 2.2 microseconds, then when its speed is increased its life is increased to 7

 micro seconds .The reason for this is its speed , so time is delayed here. So time travel is a proven one,

 but not as shown in movies on going to the future .We have gone to the future in a time of less than 1

 second. Only going to the future is proven, and not going to the past. Because many physicists believe

 that going to past is impossible ,  including Stephen Hawkins. There are many events conducted for

 welcoming future time travelers like, Perth's Destination day, MIT's Time, traveler convention.

These are conducted because of a hope that some time  travellers, may visit from the future on knowing

 about these events. Even Stephen  Hawkin has conducted one such event. On June 28, 2009, waiting 

in a secret hall, for the whole day to see if time traveller from future visit, and it was in press too.

To go to June 28, 2009 to attend the event. None came, so he proved that time travel is impossible in

 the past. To see the past in live, just look at the sky. The stars you see on sky are many light years old.

The old light of it is only seen to us only now. So from this we are seeing the past in live mode, this is

 also a kind of time travel.
