At a stretch, yes.
However, why not travel to a planet instead? Because when we can see them through a telescope, doesn't that fall among the same theory as light from stars? Because in order to see something the light must be reflecting off the back of your eye.

I'm no expert and I am probably wrong but it's just a thought. I'm not the best at explaining either so I apologise if you're confused.

In all likeliness, it probably does exist now, but it'd be government-sanctioned only. Now then, if we go with the Butterfly theory, and you did do something in the past and come back, how would anyone possibly know the difference? The timeline you came from is gone. These are people who lived with the consequences of the choices you made. They won't remember any difference, because there wasn't any. How do you know JFK was supposed to be assassinated? How do you know a government employee didn't travel back and get him killed? Maybe you were supposed to be a highly-privileged, rich family, but someone went back and killed your grandpa and took his fortune. Bottom line, if it exists, you won't know about it. The ramifications of it are too vast anyway, considering you'd be playing God (whether you believe in a deity or not), and have no restrictions. Why would a normal person ever have access to such technology? Someone would go back and win the lottery. Even if things like the Philadelphia Experiment, and such are true, the government would do their best to cover it up. Like some users said, if it exists, then at some point my future self would visit me in the past, yeah? That's horribly naive. I think parallel universes and time travel should be two different things. Parallel universe would be theoretical universes that coexist along the same timeline as ours -- in theory, couldn't that mean there'd be times where sections of two worlds could appear along the same space-- I see time travel as traveling along a timeline, and any change in the past creates a branch off the original timeline, or upon a previous branch -- meaning that, yes, the original timeline would have a check for inaccuracies, but it would be impossible to return to it. Not one person, aside from you, will have memories of the previous timeline. But that's just my opinion. I believe in supernatural and extraterrestrial phenomenon, so it's whatever. Opinion on alien life? There was a radio signal sent to us decades ago from lightyears away. No reemergence since. Opinion on demons? Houska Castle in the Czech Republic is said to house Satan, himself. There's even a throne for him. I wouldn't want to be at that precinct, much less inside, where it's true or not. I dare the ballsiest person go up there and spend the night in the throne. (Something about apparitions appearing outside the castle, and ghostly voices.) But, it's whatever. Frosty out.

This is pretty interesting. I believe time travel, but I do not believe it is something we humans should have control of. Time itself is a constantly changing variable. The light emitting from distant stars in the night sky are millions, if not billions of years old. Other galaxies time may be distorted due to some unknown factors. I also agree with your statement of how people should know if a certain event was tampered with. It's weird to think time travel would affect one's memory too. Time travel is an interesting topic. On a side note, if you've seen Interstellar then I'm sure your outlook on things concerning time would be shifted lol. Good movie

There is no such thing as time travel into the past in my opinion. However, time travel into the future is possible through time dilation. It happens every day, but not at a noticeable scale. It can occur both by immense gravity and through very fast speeds.

Science is stupid;
As a human, you can NOT go back in time or skip time, it's just impossible.

But, you can see the past just by looking in the sky, the further you look, the more you go back in time.
Best example I can give you:

When you look at the sun now, you're seeing it as it looked 8 minutes ago because the light travels at 300,000 km/s and it takes 8 mins and a few seconds for the sun's light to reach the earth. So for example, if Kim Jong-un decided to detonate the sun, we'll all see it explode 8 minutes later...

Are you guys retarded?
Of course it's possible.

Case in point.

time travel in the past is not possible, Since there is no way to go back in time and never will be, But time travel to the future it might be possible, I remeber reading a few years ago that like if u spend 50 years in space like 60-70 years would have passed on earth so you would actually going into a future of 20 years :p
