How close do you conjecture we actually are towards inventing time travel?

Newton believed it (or was it Einstein?) No matter. (Ah, riight, I recall, it was Einstein, I think(?) )

What are your thoughts pertaining to when (no pun intended.)

We're already able to go forwards in time (albeit very, very little) through time dilation. You just have to travel very quickly. For example, if you were to spend six months on the International Space Station you will have traveled a whopping 0.005 seconds forward in time.

As far as travelling backwards in time? Not close at all.

Maybe, but it wouldn't be what you usually see in fiction. If I remember correctly, Einstein (who I'm pretty sure is the guy you're talking about) based his ideas on time travel on his theory of special relativity. The idea that time lapse is based on the relative speeds of the observers reference frame. If we do invent time travel it would probably be like that. A form of transportation that moves so fast that time around it slows down to a tremendous degree, and the occupants of the vehicle will not experience the flow of time the same as everyone else. Making a years long journey seem to last only days, or minutes. So no going back in time, only forward.

Not even close. Yeah, we can solve for "Y" in an "X" world, but Z, W, and ad infinitum, would not be possible in my or your lifetime physically.
The amount of energy and mass are too astronomical and expensive. We might be able to create a hole in spacetime to observe, but even that would take the resources of nations, and besides, you could never view it directly, as that would change the future, and you would not know the difference that anything had been changed. So the observer would have to be "Outside" the plain of reality, in order to observe. But also, after having done so, would not be allowed to step back into that new reality, but instead would have to go back to their own reality that has never changed or observed.
In other words, just eat the donut, and stop worrying about the hole. It has no flavor, and no work or profit will ever come of it.

I don't think going backwards in time is possible.

And if it were, I imagine pushing a button and nothing happening because you keep forgetting that you were going backwards in time. It'd be like pressing a rewind button but you don't retain the fact you did it and it was pointless. I think xkcd sums it up in an amusing way.

According to Andrew D. Basiago, team leader for Project Pegasus, http://www.projectpegasus.net/, we did. We being the US. We've gone back in time and even been on Mars.

I believe that eventually we will just don't know when but know not in my lifetime.

If I buy anime goods on eBay from a seller in Japan, doesn't the package travel backwards in time as it crosses the international dateline?

QED, time travel.

Yeah it does,due to time zones.For instance you could travel to future by going towards eastern asia. Relatively speaking.

We're all time travellers here.

Except the frozen people, they're stuck in the past and need to let it go.

Not sure it is even possible maybe quantum physics will shine some light .

We will find out in our lifetimes most likely as most of us are likely to live a few hundred years of science keeps progressing at its current rate

Pretty much this. If time travel exist the world would have already compensated for it and any unplanned travel would be prevented unless someone had residing Steiner or some super power that allows you to defy the universe.

Only other possibility might to be jumping between parallel dimensions where everything runs behind this dimension.

Time travel is a cool concept but its just impractical. If someone went back in time to change ww2 so Hitler won then the time that they came from wouldn't exist, intact they might not exist. If the situation in the future changed then they wouldn't have traveled back in time to change ww2 so their changes wouldn't have existed so ww2 would be lost by Hitler setting up an infinite loop of disconnected possibilities.

The only true way to time travel even if its possible would be to create a loop in which your changes would not affect your future ability or decision to jump into the past. Think Okabe convincing his past self that kurisu died when she actually didn't thus preserving a loop that ensured he arrived at that same point no matter what.
