Using a time machine would be more difficult than it seems.

Science Blog was started in August 2002. It lives, breathes and eats press releases from research organizations around the globe. Most of what you read here are press releases from the outfits named in the stories themselves. Got a news story you think belongs here? Let’s talk.The other half of the equation is blog posts from readers like you. So if you have an interest in science, drop us a line and we’ll hook you up so you can join others in an ongoing, vibrant dialog about what makes the world tick.

Okey dokey. if there is time travel, then any alterations to history would become history. thus they would be imperceptible to everyone else in their own personal timeframe. so it follows that any change to history has already happened, and will continue to always happen. ultimately, everyone’s, especially the time traveler’s, past present and future becomes their immutable past, regardless alterations. in fact, in accomodation of those alterations. so that means that history is not a story which is delicately balanced on events. it is a jigsaw puzzle, with each perception of time fitting together to form a picture, which is balanced not on events but on points of view. read some douglas adams. he explains it better than i

The earth is not an inertial frame. It is accelerating around the sun. same goes with the sun, or for that matter, pratically ANY object in our universe. However, the relative accelerations are pretty small so it is usually acceptable to estimate the earth as an inertial frame. but yea, you are right in that you’d probably end up only a few hundred feet above (or below) your original location if you only go back a few hours….
The current idea is to turn on a machine that somehow connects through the time dimension in a loop between itself in the future and itself in the past. Things enter this loop in our time and leave it in another time when the machine was/will be active.
It would only work for light at first, restricting its use to the transfer of information, but if we found a way to transport matter it would likely use a similar effect. Spatially, travelers would appear in the same position that the machine is located in that time frame.
If the scientist had travelled through time, but not through space, he probably would have travelled roughly along the same path as the earth, since he would have been in an inertial frame of reference.
If anything, he would have ended up high in the air over the earth.
But if we’re ignoring that little bit of relativistic mechanics, you forgot the fact that the sun is travelling at enormous speeds around the edge of the galaxy, which is, itself, travelling at huge speeds relative to other galaxies around it. But taking relativity into account, the earth should be pretty much stationary as far as the scientist is concerned, unless he moved into the sun’s inertial frame to travel through time, in which case, the acceleration alone probably would have killed him… Bending space, though, isn’t much different from bending time, so if he invented a time machine, I’m sure he could have easily had it manipulate his position in space as well, although it would be pretty unnecessary.
I am not able to know that how it works. In fact I think that is it possible to make that type of imaginary machine. Please get in touch with me.

To kill our grandparents ofcourse.
We only know one version of history so far. The victors side of history. Being able to go to the past would allow us to rewrite what we think is history, and actually get it right. It could also disprove or maybe just question many religions and beliefs many people hold as fact.
ah
hehehehe
make another version which takes into account string theory
If we built a time machine, why would we go into the past anyway? I mean, we already know how the story goes so far.
