Make it simpler. Think about traveling back in time 60 seconds.
First, make sure that you get to a different place so that you don't accidentally occupy the same place that you were in. Second, make sure you move to a spot where no one was, 60 seconds ago.
Now imagine that you are there. You have travelled back in time. All around the world, blood flowing through people's veins has reversed and been backed up to their heart. Water absorbed in root systems everywhere has discarded its water. Great masses of iron and steel ships have reversed their course. The mass of the planet has been reversed in its forward travel as well as its rotation. The sun has sucked up the gasses and energy it has produced.

What mechanism - what power was expended to reverse all of the physical happenings in our world? In our universe? Did something reverse the path of all the stars in our Galaxy?

I would content that once something is done, it cannot be undone. The clock cannot be turned back.

However...
:-)
Think about traveling into the future. This would be easy, since every night, most of us jump 6 to 8 hours into the future. I know that we have actually been laying in our beds, but as far as our consciousness is concerned, we skipped 6 to 8 hours of reality and jumped into the future. This is relative to the person sleeping right?
What if I told you that your entire body, the aging process of the cells in your body could be suspended for a time? Relative to you, you would have travelled into the future. But you could never come back, because once something is done, its done.

Einstein's theory of relativity was proven when scientists took hyper accurate clocks that could count down to trillionths of a second, and synchronized them, then separated them, and put them on airplanes flying opposite directions around the world - twice. (A trillionth of a second is .000000000001 - a picosecond)
The clocks were compared to the stationary clock in the Naval observatory. (which is moving with the earth's rotation and orbit)
According to Einstein's theory of relativity, the faster a mass is moved through space, the slower it's own physical properties function because the internal energy of the object is sapped due to it's movement. (Energy = Mass x Time, squared) This velocity creats a relative slowdown of the object, and causes it's relative perception of jumping into the future.

So, about these clocks... the one that was moving westward was traveling slower than the Naval Observatory in the surface of the earth. the clock moving Eastward was moving faster than the Naval Observatory. The clock moving westward gained time, because they were moving slower through space, while the clock heading Eastward, moving faster, had lost time. The transpiring of time had slowed down for the eastward clock, meaning that the electricity (electrons) traveling through the clock (or orbiting the caesium atoms) slowed down just a bit. One could easily assume that the electrons orbiting the atoms in all the matter in the aircraft also slowed down, and therefore the cellular aging of the pilots and passengers would slow down as well. Not just that, but their neurons didn't fire as quickly as ours, so their perception of time slowed as well.

Could you imagine how quickly time would pass if one could become completely still in earth's orbit and wait for the earth to come back around? More than a year would have transpired for that astronaut with only one year transpiring for the earth.
Could you imagine an entire solar system, zipping across the universe at 1/4 the speed of light populated with civilized people? We would look at their planet through our telescopes and see a bunch of people just standing there, in mid stride, going about their lives in slow motion. (if it were possible to view them through telescopes that closely)

So... how fast is our planet moving? How fast is the sun we orbit moving within the spiral of our milky way galaxy? How fast is the whole of our milkyway galaxy traveling through the universe?

Imagine that our solar system, our galaxy is also moving very quickly through space, but we don't realize it. To an entity that was geographically motionless in space, we could be moving around like we are in syrup.
Any intelligent being that caught up to us (matched our velocity through space) would slow down (perceptibly) as much as we are and then they would suddenly appear to us as photons bounced off their ship an hit our eyes. When they wanted to dissappear, they would just become geographically motionless again and all of our world and solar system would zip by... they would effectively dissappear because our perception of time is moving so slowly.

The implications are tremendous! I should write a novel.
Oh, yeah... this entire work is copywrighted.... so... like don't plagerize me.
;-)
(How do you spell plagerize?)

Well I never thought computers are the best communication and whoever thought it could go through signals to unite with others. I would not believe it 30 years ago. Science has come a long way so who am I to say that time travel is possible!! We live in a modern world today compared to what we thought was impossible years ago. I am 62 years young and it is wonderful to see what changes have become in my lifetime.......

We all travel through the time dimension every day, and there's nothing abnormal about it.

However, it's impossible to travel to the past for one simple reason: If time travel (to the past) will ever be invented, we'll have already known it was invented because we would have encountered some chrononaut (time traveler) at some point in history.

Yes and no. Einstein proved it was impossible but who knows where science will go. But if we traveled back through time to fix something we'd be stuck in a catch 22.

Not currently. But, in the future, possibly. I believe a significant portion of UFO sightings are not Aliens, but, travellers from our own future.

Yes we are traveling time every day. In this moment I am writting this answer for you, and the next moment I will submit my answer. Then maybe in a few moments latter you will see what I wrote in the pass, and theirs your time travel.

einstein did not say it was Impossible. anyways. yes, i think it is possible. not in the near future, but sometime before man destroys himself, we will figure out how to travel through long distances in time. but i think that is what will lead to our destruction

Technically we are traveling through time, it doesn't appear though because of relativity. There is no shortcut or backroom that allows us to travel any differently.

no, the human body can only stand a small amount of G-force. it may be thousands of years before man could devise some vehicle that could do this. I do not believe in warping space. it sounds good in the movies or tv

According to the laws of physics,yes,a time machine can be created.
