Is the concept of time machine impossible

I don't know how to make a time-travel machine, but I do know how to travel to the future, theoretically.
Theoretically, time travel to the future is possible, but VERY unlikely with today's technology. In the world of astrophysics, there is this little-known phenomenon known as "time dilation." Basically, this means that the stronger the effect of gravity, the slower you move in time. So in a place with low gravity, such as outer space, time will move faster than back on earth.
Pretend that two people are holding clocks, one person on Earth and the other in space. Now, for each person, time will seem like it's moving at regular speed. One hour will feel like one hour. However, when the person in space looks at the clock on earth, the space clock will say one hour but the earth clock will only say 59 minutes!
This time dilation phenomenon also takes place with fast moving objects. The faster something moves, the slower time progresses for it. So, if we had the technology to build a spaceship that could fly near the speed of light, then anyone on it would travel to the future. Since this ship is moving fast, the time will slow down for it. So, after 40 years on the ship, they may have actually traveled 90 years or more into the future when they get back to Earth. So, if they leave in 2010 and travel for 40 years, they may think its 2050, but on Earth the year may actually be 2100...they traveled into the future! We may never be able to do this, since there are billions of problems that we'd have to overcome, but this IS a possible way to travel to the future.
I hope that helped.

Time
look at the clock and concentrate your thoughts .
the time travel is highly related to speed on your mind and teh levels of your thought .
speed itself penetrates the time.
i will conclude you to a research not about the gossips
a super sonic plane when traveling at about over the speed of sound recorded a sudden change in time from its point of origin and inside the plane .
why ?
lets go to the 1st thing i told about look at the clock and stare it for some moment .
the time gets slows down by the speed of your thoughts you get what you wanted you can actually feel getting 1 second converted into 3 or 4 .
on the other hand some times when you have a lot of things to think about and lot of things to do you see the time running fast and faster .
what does it mean .
Time is not stable for any of us for most of you 1 minute means holding a cup of coffee and take a sip.for others it will be watching the coffee cup empty and how they drink it too fast .
the logic behind it is simple
time revolves around every individual with different metrics actually , it depends on the way they react toward things and understand it.
the concept of time machine will be based on simple Principals when understood . Once we have explored all the motion and its units even within the strings and we are able to control subastance like the photons of light , radiation emitted
the strings vibration changes etc.
We have to hit the 0 before moving towards the 1 and -1
coz in the world of time its always 1+1+1... all the time once we are successful to create environment with no time limit all what i say 0 we will be able to travel time.
and if you think we can do that we can move with the concept of TIME machines .
cut the theory about the pizza slice and cone this is what the basics are.
HAve a nice day

Theres nothing in today's laws of physics as we currently understand them to rule out time travel. Time travel to the future is certainly possible, and its already been done (on small scales). All you have to do is go really fast, or be around stonger than Earth gravity, and as far as you're concerned, you've just traveled into the future. Dont worry about the details, but clocks that move fast and/or are subject to strong gravity tick slower than those that don't. Thus compared to someone else with a normal clock, you're now slightly younger than them in the future. They did a test with airline pilots, and I think astronauts carrying very accurate atomic clocks to measure this, and it was definetly confirmed.
As for time travel to the past, who knows. Its probably not allowed, but new laws of physics are being developed that may allow for it, in theory. See String Theory on wikipedia to get an idea for past time travel.
Quick summary: Time travel to future: possible, already been done, just go fast and/or be around lots of gravity. To the past, we'll have to wait and see. But think about this, if time travel to the past is possible, why have we never met someone from the future??? Probably impossible.

Don't know about *you*, but I go to the future all the time.
For instance, I've gone about an hour into the future while I was sitting here at the computer tonight. It was 3:30 AM when I sat down, and now it's 4:34 AM.
No machine - I'm just naturally talented, I guess....

Stephen Hawking said it best: "I would not bet against the existence of time machines. My opponent might have seen the future and know the answer." If one of the best theoretical physics minds in the universe would not take a bet against time machines, who am I to argue?

It's very confusing, especially how you think about stuff like, if you went to a planet that was far enough away, and built a telescope that was powerfull enough, you would see dinosaurs walking around cause the light hasn't reached your eyes yet.

We can , in our mind, but not with our bodies. To move forward or backward in any dimension, we need some special skills and energies. While we could move in two dimensions fairly easily, it took thousands of years of scientific development before we could move in the third dimension, vertically up and down.
Thus in future, we may have the technology to travel in time.

i don't know but someone needs to invent one or something. it would be kinda cool. but i read this book by Dean Koontz (it was either Fear Nothing or Seize the Night i can't remember which one it was in specificly) and these underground labs had created this "night train" that goes into the future and they had opened up a whole can of worms by doing that! so maybe it would be cool and then again maybe not...

I don't know about you, but I am planing to go into the future, in fact I'm going to go to tomorrow, as soon as I get up tomorrow.
A big problem with two way time travel is the paradoxes is causes, this is a fairly common subject in science fiction.

light(300ksec),gravity,mass,magnetism,, matter,and time are all properties of the big bang,we understand all of them incompletely.newton described one of these(not define) like 400 years ago,,,,,,,we cant go forward any faster than our aging carbon,,or backward to visit our former carbon,well,actually we can slow aging a tad by flying over an earth area with a stronger gravity field(clocks with cesium 131,super accurate) laws of nature are revealed slowly
