Here is a good question. Will time travel ever be possible? Forwards and backwards? Details please?

Question

I want peoples detailed insights on this subject. I think its fun to talk about as well as educational. Im not looking for right and wrong answers. Also, where would you travel in time?

Answer 1

I love talking about this...

Well, first of all, I do think time travel is possible... I remember a line out of a book that said, 'silly humans, you think you need a capsule to travel through time'.

I've always thought that dejavu was time traveling... in our minds of course - and this is why I believe that line from that book (stated above). The impulses in your brain travel at the speed of light - and we all know that to travel through time and space, we must travel faster than the speed of light. It could be possible, while sleeping on a certain level that the impulses in your mind travel just a bit faster than the speed of light. When this happens, it could be possible for you to see what the next day or week or even year holds for you.

I think that we will eventually figure out time travel. But, unfortunately, I don't think much good would come out of it; considering the fact that most people on this planet are all about themselves and how they can better their lives and leave everyone else in the dust. If it was possible to see the future............
~countries would go to war to prevent war, causing monumental -if not total- destruction of our planet.

~people would get bored with their lives, if you knew what was going to happen tomorrow or 25 years from now, there would be nothing to live for... that is part of the wonder that is life - not knowing what is coming

~one last thing; if you could see your demise, that would more than likely scare you so much that you are mentally scarred for the rest of your exsistance.


I personally believe that time travel has already been invented... the whole alien thing - how do we know that they are not us in the far future coming back to see what happened ... how and why we destroyed ourselves... hhmmm... there are sooo many possiblities to these questions... I love it.

Answer 2

Some time ago we had a question about the number of ways the Earth is travelling. The resulting motions of Earth's motion through space means that every day we are millions of miles away from where we were the day before. So any time travel has to be in conjunction with space travel to try and keep up with the Earth's motion, otherwise the time traveller will end up in empty space millions of miles from Earth.

The calculations of movement would be stupendous, but I suppose a future computer could handle it.

I think you will find that the time shortening effect mentioned by the previous respondant is negated when the travelling twin tarvels back to Earth.

It is true that the travelling twin going off at near light speed will age slower, but I am pretty sure he/she will never be able to prove it to the other twin - even if he/she sends a message back saying I'm only 25, and you are 40, the travelling back of the message will negate the time warp.

Perhaps some physics professor can enlighten us.

Answer 3

Wow, I just watched a documentary on this no more than 5 minutes ago...freaky.

Anyway, YES, it will be possible, the key is to warp time. We all know that time is a straight line, linking the past and the present, but if we could make a loop of time (a circle), then we could travel from the past to the present because they would be on the same point. Einstein had the right idea, and there are many people working on time travel these days. It is a feasable concept, I'd tell you more about the physics behind it, but then it'd just get too long and confusing to read.

To answer your question, yes forwards and backwards will both be possible (actually, it'll be easier to move forwards than backwards). In theory, we could actually say that astronauts have traveled time (for a few seconds) because of the theory of relativity.

Answer 4

Yes time travel is possible and can happen in 3 ways.

First if you can find a worm hole in space that you can travel into.

Second is you get a train and have the track laid in a circle and you get the train going very very fast. You have to know the right speed to go at cause you would have to go faster then the earths rotation. I had a teacher tell me that one before.

But once you went back in time or went forward in time you would have to becarefull what you did.

The last way to do time travel is by looking up into the stars at the light of the stars. If you was in another glaxey and you was looking at earth you would not see the present day. You would see what the earth looked like in 1492. That is because light takes many many years to travel.

Hope that answers your question

Answer 5

/:) I like to talk about stuff like this too. I'm not into science or anything, but I like to be creative, so I'll give you my views.

I think time travel will be possible. In the early stages, this is really freaky, but it's an idea. Everyone will wear contacts and they will video tape every moment of your life. You get to buy this clock and then set it to the time you want to go back to and lay down. Then you would be able to watch your life and virtually move around with your mind. That's not really possible, so yeah.

I heard scientists are able to transport atoms from place to place like teleportation or something like that and then they're finding new elements in the earth or something like that and developing an invisibility cloak at this time. You could search invisibility cloak in yahoo or google.

Another idea... I don't think you'll ever be able to travel forwards in time because of this one thing and that is no one will ever know when the end of the world will be so if you could travel forward in time, it would totally probably make that false. Revelations in the Bible.

If time travel were possible, I'd go forward in time to see the woman I'd marry and to also see if I made any mistakes that mid-guided my life so I could correct them now in the present.

Answer 6

The only way i can imagine time travel is by traveling beyond the light rays that are carrying certain events and then rewatching them. So it is possible to see what has happened in the past, just think of all those stars we see in the night sky. Many of those stars do not exist anymore, we are just seeing the light rays that are finally reaching us. So, if we could somehow get out beyond the light rays that are hurdling into space and then face back towards earth with a huge telescope, then we could rewatch our history.

Answer 7

The problem is: if somebody travels to the past it already happened, so does he exist in the present? Did he ever existed? Would you believe you're self that you came from the future? Would he/she remember that he/she traveled through time? Would his body remembered that it was in a shape?
Imagine this: you have a time machine, take a simple clock and send it back to the past, 1 minute to be exact. Nothing changes, because your clock was set forward 1 minute when you first put it in.
If you send it to even further past, say 100 years, nothing again, you wont send that exact clock but a different one.
But to a beholder (theoretical) who could stay at that exact point of time could see you sending back clocks like crazy,

Answer 8

There is no such thing as time except as a human concept required to separate events into past, present, and future. There is no such thing as time, as in "absolute time" where some Master Cosmic Clock ticks away the correct time for all the universe.

If you travel away from Earth at some velocity close to the speed of light and can somehow keep track of the passage of "time" back on Earth, you'd see clocks moving faster. If someone on Earth could keep track of the passage of "time" on your spaceship they'd see "time" moving slower. Which observer is right? Neither and both are right because there is no Cosmic Master Clock they can use as validation.

Answer 9

I'm not quite sure if it's possible to travel back in time, but it's possible to travel forward. Einstein's theory of Relativity states that the faster you're moving, the slower time goes for you. For example, if twins decide to test this theory, and one goes off in a rocket ship traveling at near-light speed and the other stays on earth, when the one in the ship returns, s/he would find that her/his twin would be significantly older (depending on the number of years he/she was in the rocket ship). It's kind of hard to describe, but I hope that gave you some insight.

Answer 10

It depends on what you base time upon. If you base it on the speed of light, then you are dealing with the light cone. At the speed of light, it would take 4.22 light years to reach Proxima Centauri. Let's say you use a wormhole and get there in one hour. You have just escaped the light cone and thus traveled through time. If you look back at the earth, you're now seeing into the "past" as related to the speed of light.
