Is really Time Travel possible?

Let's try to reach depth of this amazing question.

** Their are two way's that you can achieve Time Travel **

Way-I

Anything which is part of the earth travels' at rate of 24 Hour's Per Day.

As we all study in school about the Photon particle something which is Mass-Less and Charge-Less but still having a Momentum.

Photon is a particle which related to Light, and light is something which is related to sun. So the sunlight is packets of photons which scattered all over the atmosphere during day.

So why I m telling about Photon and Light??The one method to achieve the time travel is directly linked to this.

Suppose you are able to travel at speed of Light. 

Speed of Light = 299,782,458 meters per seconds.

Some scientist said that if you are able to travel at speed of light then you have two possibilities:-

1:- You will Die. (or)

2:- You will Travel to time Either Forward or Backward ("Most Probably Forward!!")

Let's Elaborate this:- 

We all know about our childhood Physics that when a particle is in movement then it's static mass will change according to their movement or velocity.

Here m(v) denotes the mass of a particle at velocity (v).

And m0 denotes the static mass of the particle.

C is the speed of light. 

Derivation of this equation.

Now, this theory is not so popular that you will make a time machine which have max-speed as light.

This sound's very unrealistic but maybe somewhere , sometime this also may be true.

But right now for us this theory is like a mystery, which require lot's of time to solve.

Till then jump to second way.

Way-II

The great 20th century scientist Albert Einstein developed a theory called Special Relativity.

The ideas of Special Relativity are very hard to imagine because they aren't about what we experience in everyday life, but scientists have confirmed them. This theory says that space and time are really aspects of the same thing—space-time.

There's a speed limit of 300,000 km's per second (or 186,000 miles per second) for anything that travels through space-time, and light always travels the speed limit through empty space. 

Special Relativity also says that a surprising thing happens when you move through space-time, especially when your speed relative to other objects is close to the speed of light (C). Time goes slower for you than for the people you left behind. You won't notice this effect until you return to those stationary people.

Say you were 15 years old when you left Earth in a spacecraft traveling at about 99.99% of the speed of light (which is much faster than we can achieve now), and celebrated only 5 birthdays during your space journey. When you get home at the age of say 20, you would find that all your classmates were 65 years old, retired, and enjoying their grandchildren! Because time passed more slowly for you, you will have experienced only five years of life, while your classmates will have experienced a full 50 years.

This is something Time-Travel in word's of Albert Einstein.

Now, it seems like time travel into the future is possible, but we would need to develop some very advanced technology to do it. We could travel 10,000 years into the future and age only 1 year during that journey. However, Such a trip would consume an extraordinary amount of energy, or may be in future we will time travel by just space travel.

We will never understand the space and universe completely.

I think after so many invention still we've not even explore 1% of something outside of the Earth, there are solar systems, galaxies, universes, multiverse's, Giant Star's and so on...
