Time travel
Hey, guys time travel is the most controversial topic in the world. Many a scientists support the time travel but many do not support it . But wait , there are some theories that prove that time travel is possible to the future. So, let us begin our todays topic Time travel.
Types of Time travel-----
*Time travel to the future
* Time travel to the past
Time travel to the future
Experiments and theories for the time travel-
Any theory in this world is either proved experimentally or mathematically but the most condratictory topic time travel is proves mathematically. There is also a experiment proving time travel but it was for just some nanoseconds .
So let us discuss the experiment-
Hafele-Keating Experiment(October, 1971)
This experiment was performed by astronomer Richard Keating . Richard took four atomic clocks and he revolved two times round the earth and after revolving when he came back at USA in the observatory then he discovered that his atomic clock was showing time less than the clock at earth by some nanoseconds. What this experiment proves , it proves that time travel is actually or practically possible.
Now, you all were thinking that nanoseconds of duration could not prove it because the clock would be wrong but you are not right here because he was using atomic clocks that could give right time of every thousand parts of a nanoseconds.
You would also think that what happened there, the clock at the earth became faster or the clock in the plane became slower , actually the clock (atomic clock) in the plane became slower.
The object having the more speed the slower will be the time for him .
But, a question here arises that what someone could do going to some nanoseconds of future. Yes you are right but going to longer period of duration of future will need some other impractical requirements(at present).
If we want to time travel to the future then we could use this method but if we want going to the years of the future then we will have travel with a very very very high speed and that is near or exactly the speed of light. This was exactly said by the genius scientist Stephan hawking.
When u travel at the speed of light the time became slower for u but the time at the earth would be faster compared to your time. But going to the future is one way because if u travel to the future then u would not return to ur present time .
If u travel three years at the speed of light then 900 years will have been gone on the earth. This ratio is not an assumption it is given by a equation.
Time travel as u have often heared that it is theoritical but not practical because it is not possible to make a object that travels at the speed of light with the present technology . If we suppose that there is a object that could travel with the speed of light but it would be totally impossible to give a power source to operate it.
So, time travel to the future is possible but not practical.
Time travel to the Past-----
Time travel to the past is more controversial than the time travel to the future because of a paradox(Grandfather paradox) known as the grandfather paradox.
Grandfather paradox
According to this paradox, let us imagine that somehow you imagine to go the past and killed your grandfather than how will you exist. This is a very confusing paradox
Anymore way for travel to the past-
According to Stephan hawking it is possible to travel to the past through Wormholes. It was first discovered by the scientist Albert einstein and so also known as the Einstein rozen bridge.
What is wormhole?
A wormhole is understand to as the tunnel that joins two places or two different times. But it is although a theory and it only exists mathematically. Scientists say that wormholes exist but no any wormhole is seen by anyone in the world officialy.
Is it possible to travel back in time?
As I have made u understood that time travel in the past is mostly given by the mathematical expression. So it mostly seems to be impossible in the present time. It could exist in the future.
What is the formulae for time travel?
The the formula for time travel is given by einstein that is -
E = mc²
E= Kinetic energy
M= mass
C= square of the speed of light.
Is it possible to build a time machine?
There is no formulae for the making of a time machine and it seems to be a science fiuction to build a time machine.
What are the rules of time travel?
As I have already make you understand all the rules of time travel to the future or the past. For future the rules are to get the speed of light and for past wormholes are there but both are only practical.
Does the past still exists?
The past and future do not exist and are only concepts used to describe the real , isolated and changing present.
Is it possible to travel faster than light ?
There is a very less possibility to travel faster than light with the help of present technology and we could say it a future technology.....
So, this was the complete info about the time travel....
THANKS.....
