In 1900, television was a myth, in 1925, color television was unthinkable, in 1950 cable TV was a wonder, in 1975 digital-satellite image TV was a rumor, just as time travel is today... what's "not possible" for television today?
I remember some movies from when I was a kid, about communications possible of transfer image and sound at the same time... and we all look at that like a great idea with an uncertain future... today I can talk and look at whoever is on the other side, and that's on my phone, is incredible the things you can do with a high speed, large memory and good connection from your PC...
A lot of people will tell you that those are only creations from some ones imagination... but... wasn't it like that as well as when Jules Verne talked about a submarine, years and years before the first one was actually created?
I think is a simple matter as: we see what the ones in the power let us see...

I hope so. The discovery of a parallel universe, wormholes, and other things seem to me that it might just be possible in the future if technological curve continue to rise exponentially.
There are also other hypothesis, like the slowing down of speed of light, that affects scientists on the probability of time travel. They say now that time travel is impossible in the near future. I like to think so otherwise.

Ask the astronauts. Their clocks were, I think, about two minutes slow when they returned to earth from the moon.
Time is relative. Take two people walking parallel to each other 10 feet apart with one 5 feet in front of the other one.
Get them to throw a ball between them. If you look from the side, the ball will take x seconds to travel what appears to be five feet. If you view them from above, the ball takes x seconds to travel approximately 13 feet. Relative time, depends on your viewpoint.

Virgin Galactic is engaging in try flights of their finished suborbital area craft now and in a pair years will start up commercial flights at $2 hundred,000 in holding with individual. yet that would not take you into orbit, basically above the ambience for 5 minutes or so and then precise decrease backpedal back.

I read a news article some time ago,which stated that it is possible to build one,but it would be half the size of the Atlantic,& would bankrupt every country on the planet.How effective it would be is anyone's guess.

I hate to say that anything is impossible, but if time travel were eventually to be invented, we would have already met time travelers from the future, I'd think. That seems to be a reasonably good (though by no means airtight) argument that there will never be time travel.

Well, I had written a really long answer that got wiped away because I had to login in again. Grrr.
Anyhow, the short version.
A time machine like in the movies is not very likely.
However time shift occurs every day. GPS (Global Positioning Systems) use the time it takes for a signal to reach the satellite as a means to calculate distance. In order for all the satellites to make accurate calculations of time to distance, they must all use the same reference of time.
But because the satellites are moving faster than the reference clocks on Earth, their time appears to be slower than the clocks on Earth (and from the satellites point of view, our clocks on Earth appear to go too fast).
So every 1-3 years (roughly) they will add a Leap Second to resyncronize the clocks to the "same time" and allow GPS to provide accurate readings.
This is important because being off 10 feet can make a big difference to a plane landing, or drilling a hole in the ground, etc...
Note: the clocks used are called atomic clocks. They all count the frequencies given off by cesium atoms, which is an excellent measurement of time.
In summary, the faster you go (or the more massive you are) the more time will distort "around you". Your time will seem normal, but everyone else will seem like they are going fast.

It has already been achieved.
If memory serves me correctly it was a Russian Cosmonaut who spent so long orbiting the earth that he actually travelled in time by about 2 seconds.

If time travel was possible, someone would have already gone back and prevented your parents from meeting.

May be but not for a very long time
