I think that to travel time we need to go faster than light because lets take an example, light takes 8 1/2 minutes to come to earth from the sun. So, we are seeing the 8 1/2 past of the sun but the sun is different in real view. So, we can time travel past but what for time travelling future - if we go faster than light that is 299,792,458 m / sec we can acctually travel time.
I say this...
What is your opinion friends?
This is a topic that has always fascinated me, though I'll confess that I'm very much a layman. Another way, in addition to the faster than light method, has been proposed by some physicists. It is based on travel through wormholes, portals through spacetime that have been predicted by, or at least are not inconsistent with, general relativity. The idea is that one would enter a wormhole, then "come out" the other end at another point in spacetime. The limitation is that a person travelling through a time travel machine based on a wormhole could not travel back to a point in time before the machine was developed.
Perhaps a way to "kind of" time travel is to pursue cryogenic freezing. If a person were to be frozen alive and preserved for hundreds of years, he/she would wake up to a new time.
This is not time travel properly speaking, but it is a way for one person to potentially live in multiple time contexts.
If the term "time travel" doesn't have to be taken literally, then I'd say reading is a form of time travel. Authors usually write for their contemporary audiences, so they reflect the values and attitudes of the time in which they were writing, which may be significantly different than our own.
I have to say I like mwalter's view. People can time travel everyday (through literature and film). People are also able to look online and see how life was "way back when." As for the possibility of time travel, I would think that cryogenic freezing would be a plausible option (not saying that it is something which could be an actuality).
I would have to say reading a book is a form of time travel for me. I can get so caught up in a book I lose all sense of where I am, and I feel transported to another place and time. It's like I stepped through a door and am in another dimension! Some movies are that way, too. When I recently saw The Hunger Games, it was like I was right there living it with Katniss and Peeta.
Good novelists want it that way. They want to make their literary creations come alive for their readers. In a way, it's time travel.
A lady named Miss Write
Could travel much faster than light.
She departed one day
In an Einsteinian way;
And she returned the previous night.
eto! can you give more info of miss write
Well, she departed three times. Now she is three days in the past. Maybe if we go the see the Mad Hatter (his watch is three days slow), he will help us talk to her.
Most people say that moving faster than light is the main idea. However, it means that you will only be movng faster than the things around you. I believe that if gravity distorts time and slow it. Therefore, this means that you could create an extremely dense ball of matter, like a black hole, you could stop time. If people can reproduce such things and increase its density and gravitational force, time may reverse at some point after time around it completely haults.
It's only a theory that I started thinking of.
We measure the passage of time in seconds, minutes, hours and years, but this doesn't mean time flows at a constant rate. Just as the water in a river rushes or slows depending on the size of the channel, time flows at different rates in different places. In other words, time is relative.
But what causes this fluctuation along our one-way trek from the cradle to the grave? It all comes down to the relationship between time and space. Human beings frolic about in the three spatial dimensions of length, width and depth. Time joins the party as that most crucial fourth dimension. Time can't exist without space, and space can't exist without time. The two exist as one: the space-time continum. Any event that occurs in the universe has to involve both space and time.
In this article, we'll look at the real-life, everyday methods of time travel in our universe, as well as some of the more far-fetched methods of dancing through the fourth dimension.
Write two ways to travel time.
Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space. Time travel could hypothetically involve moving backward in time to a moment earlier than the starting point, or forward to the future of that point without the need for the traveler to experience the intervening period (at least not at the normal rate). Any technological device – whether fictional or hypothetical – that would be used to achieve time travel is commonly known as a time machine.
