Can We travel throught time?

Answer 1

No, we can't

Answer 2

Have you ever overtaken a bicycle in your car? Consider that provided you both continue down the same road the cyclist will be seeing places now that you you saw 5, 10, or 15 minutes ago. You know the cyclist's future.

Consider that if you landed the Tardis on a big asteroid, and went backwards and forwards in time a few hundred or a thousand years, but remained on the asteroid, each time you stepped out the door, the asteroid would probably look exactly the same, and nothing would have changed.

Time travel really means culture travel doesn't it? Travel forward to experience a more advanced technology, and culture: travel backwards to see cultures that existed before ours.

Answer 3

What is time? Is time travel possible? For centuries, these questions have intrigued mystics, philosophers, and scientists. Much of ancient Greek philosophy was concerned with understanding the concept of eternity, and the subject of time is central to all the world's religions and cultures. Can the flow of time be stopped? Certainly some mystics thought so. Angelus Silesius, a sixth-century philosopher and poet, thought the flow of time could be suspended by mental powers:
Time is of your own making;
its clock ticks in your head.
The moment you stop thought
time too stops dead.
The line between science and mysticism sometimes grows thin. Today physicists would agree that time is one of the strangest properties of our universe. In fact, there is a story circulating among scientists of an immigrant to America who has lost his watch. He walks up to a man on a New York street and asks, "Please, Sir, what is time?" The scientist replies, "I'm sorry, you'll have to ask a philosopher. I'm just a physicist."

Most cultures have a grammar with past and future tenses, and also demarcations like seconds and minutes, and yesterday and tomorrow. Yet we cannot say exactly what time is. Although the study of time became scientific during the time of Galileo and Newton, a comprehensive explanation was given only in this century by Einstein, who declared, in effect, time is simply what a clock reads. The clock can be the rotation of a planet, sand falling in an hourglass, a heartbeat, or vibrations of a cesium atom. A typical grandfather clock follows the simple Newtonian law that states that the velocity of a body not subject to external forces remains constant. This means that clock hands travel equal distances in equal times. While this kind of clock is useful for everyday life, modern science finds that time can be warped in various ways, like clay in the hands of a cosmic sculptor.

Answer 4

Okay, NO, .... but is it suggested that if you can travel faster than light you could travel backwards in time RELATIVE to where you travel from.

This has been demonstrated using 2 atomic clocks. One on the space shuttle and one on earth. Because of the very high speeds the shuttle travels (no way near the speed of light which is aprox 186,200 miles/sec) its has shown that the clocks, which were sync'd before, were on return to earth were several seconds different. The one on the shuttle was slower, thus a movement backwards in time.

Going forward in time is a little trickyer to explain....

Answer 5

This is the billionth time someone asks this... NO! You cannot travel in the past or the future... You may see stars and other light year away bodies in space.. That's the only past you gen see. To travel to the future you have to increase your speed to that of nearly the speed of light and then come back to earth to be several years younger than the others... For you it may "seem" that you have travelled to the future.. For others time moved like you left it. But to travel and reach that speed you have to have infinate energy to keep accelerating you which is impossible.. Also, trying to reach that speed would kill you...

Answer 6

One way to travel back in time is to ride on something that travels faster than light.

Many great minds say we cannot travel faster than light, not now, not ever, it is impossible.

I think everything is pretty much possible and someday, if the human species lives long enough, we may have something like "warp speed". For now, all we can do is dream.

Answer 7

Yes you are traveling through time at one second per second.

In the press there have been claims of time travel, quantum-mechanical phenomena such as quantum teleportation, the EPR paradox, or quantum entanglement might appear to create a mechanism that allows for faster-than-light (FTL) communication or time travel, and in fact some interpretations of quantum mechanics such as the Bohm interpretation presume that some information is being exchanged between particles instantaneously in order to maintain correlations between particles.
This effect was referred to as "spooky action at a distance" by Einstein.

Nevertheless, the rules of quantum mechanics curiously appear to prevent an outsider from using these methods to actually transmit useful information, and therefore do not appear to allow for time travel or FTL communication. The fact that these quantum phenomena apparently do not allow FTL/time travel is often overlooked in popular press coverage of quantum teleportation experiments.

How the rules of quantum mechanics work to preserve causality is an active area of research.

Answer 8

You are traveling through time. If you want to travel into the future, travel near the speed of light then come back to earth, the earth will have aged and you will not have.

Answer 9

yes..although the cultural concept of time relates to segmentation of space...this is what is causing stress in the world.If you are at home and you read a book watch a film listen to music e.t.c.then effectively you are in space for that absorbing 1hr or what ever you call it...if you are daydreaming or concentrating on a solution to something...these examples are likened to travelling through space..there are no obsticales ....maybe a course in meditation would help resolve your own research into this territory...it is fascinating and rewarding...Astral Travel requires a little more knowledge though..good luck my friend....

Answer 10

No. Time is not an actual feature of our universe. There is no Cosmic Master Clock by which all other clocks should be calibrated. Time is nothing more than a concept unconciouslly "invented" by our species to separate events into past, present and future.

Answer 11

We can proberly travel 'through' time..not 'throught' though.
