I studied this theory when I was in college. I need further explanation.--If we are able to travel faster than light and if we get into the space detaching from earth and at one point if we turn back we could be able to see the events which occured on the earth. Because the events' images are not vanished.They also travel through space. Is it possible? Kindly explain.

When we look at a star we are seeing the light that left the star thousands of years ago and not a right now view of the star thus we are looking into the past. Many of the most distant stars we see are already dead or non existent but the light continues to travel. Similarly if we were right now in space the further away from earth the further back in time you would be seeing.

Hello Priya...
Well, your question starts off with an impossibility premise...
"If we are able to travel at (or faster than) the speed of light..." We are not able to do that. At present we are only able to accelerate man made vehicles to about 30,000 - 50,000 Miles Per Hour. We might possibly have gotten one or more probes going somewhat faster than that. Remember that the speed of light is 186,000 Miles Per Second. So there is quite a bit of diference between the two speeds.
When we look out into space, light from the Sun has taken 8 minutes to get here to Earth. Light from the Moon has taKen about 1 and 1/4 seconds to get here. Light from the various stars has taken years to get here. Some objects in deep space may no longer exist though we can still see them, because it takes so long for their light to reach us on Earth.
Now, your suggestion in theory poses a "what if" that says what if we could travel FASTER than light... I don't know how to spell the word "Non Sequiter" but it is a non event, a something that does not qualify for the topic at hand. And that is what this super speed you discuss is. I appreciate the fact that you wish to discuss the theory, but caution you that it is only just that, a theory. I don't think that physical proof exists in hand.

At any speed time will pass at a normal rate in your location but it is not possible to travel faster than light because it will become unstable and turn into matter. If you were to greatly distance yourself from earth traveling any speed the light would show an image of an event that may have taken place a few seconds, hours, days and ect.. ago...The travel time of light from its starting point to your eye reveals the recorded past event given an illusion.

OK. When you look at the night sky, you are seeing light that comes from stars far away. Because light takes time to travel, you are seeing what was going on when the light left that star.
If you had were, say, 12 million light years from Earth and had a telescope powerful enough to see what was going on on Earth, you would see dinosaurs walking around.
So, if you could travel faster than the speed of light, and if you had a telescope powerful enough, you could travel in front of the light wave coming from Earth now and look back and see what was in the past.
But all this is moot, as we cannot travel faster than the speed of light.

Think it out! If it was possible to travel faster than light, which it is not, you would need one heck of a good telescope to see any images that you left behind, if you had such a telescope you would be able to details of far away planets and search for life forms on them. You show imagination but you must also use logic.

Time is considered as the fourth dimension. If one can travel faster then light (according to law of relativity), he will be travelling in the past. This mean one need not to travel in the space, it can also be done on earth - if you can manage to travel faster then light.

Each entity in the universe is isolated by time.
The illusion is that the isolation doesn't seem to exist.
To put it into perspective,when you observe a person in the room with you,you are seeing that person as he existed some billionths of a second in the past.
Your perspective is from time zero,the other person has the same experience.
As the distance increases the time isolation also increases but there is a holographic overlay that lets you interact as though the time isolation doesn't exist.
This applies to fundamental particles,people and galaxies.

yes.basically space is our past.i cant really explain it but space is our past
