I don't need to believe in time travel
I received a temporal fine from the time police for endangering causality
If I try to build a time machine again I face 365 consecutive life sentances and believe me when the time police threaten that they know how to inforce a life sentance!
Heed my warning - dont mess with causality

Sorry, I'm not a physicist. lol. Length, Width, Depth, and Time are the ones we can interact on.Mr. Google said:
Not in the 'back to the future sense', it creates paradoxes which are imposssible to resolve.
Such as: if you tried to change anything in the past, it would already have been changed, so you didn't go back to change it because it happened, or more traditionally if you kill your grandmother before she gave birth to your mother you were never born, which means you never couldn't have gone back to kill your grandmother.
Some models of the universe (and bear in mind my model of physics is pretty old now and mostly comes from books designed for kids) postulate a kind of constant division, so what you could do under those models is go back in time and then proceed along a different path, without affecting your original timeline. It raises problems though, presumably you would already exist in the timeline you entered (unless you changed things so you never existed) so there'd be two copies of you, while in your old timeline you would have suddenly vanished.

what are you views?
Maybe...
It would require massive amounts of energy to punch a hole in the space-time contiunum, and be able to control it so you could appear where you wanted to.
And in my opinion, we can't travel into the future because the future hasn't happened yet.

This leads to the question, have we already (in the future?) created time travel and averted possible disatorous scenarios.
For example maybe Germany kept Einstien and they made the nuclear bomb first, so they changed that.
I'm not entirely sure, but for the most part I'm skeptical.
The way I see it, to traverse any given thing, the space or thing inbetween it has to actually exist and time is almost a man-made dimension. Time only exists because we say it does, and because we measure our manufactured seconds and hours and say "This happened X hours / days ago" or "in X years this will happen". Without anyone to observe it, time would cease to exist. It wouldn't mean the end of anything though, because nothing needs time to exist.
I'm probably wrong but that's my take on time travel.

haha thats alright. I just tried a google search and couldn t get anything so i was actually hoping you knew them hahaha
Time travel is theorectially possible (as is pretty much everything else if you get into high enough physics), but I highly doubt anyone currently on the planet will live long enough to see it become a reality.
I believe whether it may be possible or not, it is either happening or not.
I'd like to say time travel is possible, but so many laws of physics would be bent if not broken, and you cannot talk about time travel without invoking the limitless "what if?"s that will happen.
I'd LIKE to go back and have a chat with Aristotle, but I won't lose sleep over thinking whether it is possible or not.
I find it amusing that just about every single movie/book that involves time travel, has a different idea of what can and can't happen, and the extent of "what if?"s.

I think it is not possible in such way that a human form can experience it. I'd think of it like twisting all of what your are made... at once... into... Okay I'm in over my head now. Wouldn't know any details, but I assume it pretty much... um... closest word would be... "disintegrates" you.
That is a very good question and I will enjoy reading this thread.
Forward time travel is possible. Backward is not. Backward time travel cannot be achieved because of the creation of paradoxes. Forward time travel is possible, and the method of it is known, but not yet attainable with modern technology. You go as close to the speed of light as possible, but obviously not attaining it because that goes against the laws of physics, and basically the faster you go, the slower time goes by for you. So basically travel at this speed around the Earth for lets say 5 days, and stop in the same position as when you left, and you will have only aged 5 days, but return to Earth, and everyone will have aged 5 years for example. The reason you have to go so close to the speed of light, is because the effect of time moving slower is negligible at slower speeds, which is why someone traveling in a race car at 150 mph effectively ages the same as someone in the crowd spectating. Kind of off the topic, but to achieve such a speed, you would firstly need enough fuel to reach that speed, as well as slow down, because in the vacuum of space you need some sort of propulsion in the opposite direction being traveled, in order to slow down, because of the lack of a source of noticeable friction. Secondly, you would need to take into account the time needed to speed up, and eventually, in the process of speeding up, you will achieve a speed that has a noticeable shift in the speed that time goes by, so you would need to figure out the equation of exponential rise to pinpoint exactly when all of this needed to occur in order for you to reach your target destination.

Probably not, but, this coming from a Doctor Who fan, I honestly hope that one day, it will be possible.
