Is time travel possible if yes how?

 

Hello everybody, my name is K. Deepak chary. Today  the topic of our article is “Is time travel possible if yes how?”

Before knowing about time travel, we should know about the theory of relativity.

In this article, we are going to discuss about

i)                  Theory of relativity

ii)               Is time travel possible if yes how?

 

    a)  Theory of relativity

In our surroundings, every object is in a relative position including time except for light because light speed is constant at every place no force can change the speed of light. Light is in absolute position.

So, the theory of relativity states that:

i)            Every object around you is in relative motion or rest except light.

ii)          An object which travels fast for the time will be slower

 

 

Time Dilation:

According to the theory of relativity, object travels at high-speed time will be slower.

In 1971, one experiment was done in that experiment they used an atomic clock. they kept one atomic clock on earth.

And one in an aeroplane. they asked the pilot to travel around the earth. after the aeroplane completes one round, they kept both clocks together and they find some time difference that is billionth of the second more in aeroplane compared to an atomic clock which is kept on earth.

 

So by this, we can understand that increase in speed, time will decrease. If we travel with the light speed that is 3*10^8 m/s

Time will be feezed.

 

 

Space-time:

Generally, some members think that before the big bang there are no planets there is only clear space but they don’t know that

After the big bang, only the universe and space-time were formed.

Time depends on the gravity and mass of the body.

Time will be slower near the massive objects compared to less massive objects.

In our space, Blackhole is a very massive object and it brings bend in our space-time

Simply, higher massive objects bring more bend in space time.

By seeing the below example, you will get clarity about space time.

 

If we take our solar system as an example:

Sun has more mass than planets and their moons that is the reason planets revolve around the sun. as we know that planets have more mass than their moons that is the reason moons revolve around their planets.

 

By the above two example, we can conclude that space-time bends at higher massive objects.

 

b)  Is time travel possible If yes how?

 

There are many theories about time travel. Some members say time travel is possible and some members say time travel is not possible

So, there are 2 ways for time travel

 

1^st way is travelling at light speed that is 3 *10^8 m/s but travelling at light speed is impossible because light doesn’t have any mass. If any object increases its speed its mass and weight changes. light don’t have any mass that is the reason why it can travel at that speed but any the object has mass so it cannot travel at light speed.

Our 1^st way is closed because we cannot travel at light speed.

 

2^nd way is spending some time near the black hole but this is also impossible because light also cannot escape from blackhole so, if our speed is more than light speed it can possible but we can travel more than light speed so, in this way also we cannot do time travel.

 

If an astronaut be in ISS that is International Space Station for 6 months after coming back to earth his aged 0.005 seconds less than people on earth.

 

So, we can conclude time travel is not possible.
