Default Do you ever think time traveling could happen?

Explain to me how and why you think that.

Happens all the time. We are traveling through it minute by minute. But that is proably not your question. You probably are asking if we could visit the future or go back to the past.
Not likely.

If you mean like to the future or past, then I doubt it will ever happen. But like the first poster said, we're going through it every minute of every day..

Sure, you do it all the time - no pun intended. You travel backward with your memory, and you travel forward with your imagination. Otherwise, there's no such thing a time travel. You can only travel through something that actually "exists" whereas time is just a concept we use to mark an abstract (but useful) narration of events.

The undergrads at MIT hosted a large party, inviting all time travelers to attend. (2006?)

No one from the future showed up.

They got lots of coverage from national news crews, so it wasn't for lack of exposure.

I think it is impossible to travel back into the past or into the future. We are made of one big chunk of matter and cannot be compressed so small into a pin-point of light, because we would die. So how are we going to experience a certain past or future scene at a certain point in time when we are dead? All those talk of time-travel is pure science fiction and is therefore not possible. Simple as that.

Time travel into the future might be possible. If we could make a spacecraft travel over 90% of the speed of light--and that's a big 'if'--observers on Earth would see the passengers on the spacecraft age more slowly than they do. When the travelers came back to Earth, they would be younger than their identical twins who stayed home. So, in effect, the travelers would have traveled into the future, relative to Earth.

Most people rule out time travel into the past because it would entail logically paradoxical sequences of cause and effect. For instance...

You enter a time machine; you travel back in time; you murder all the people who knew the theory and practice of time machine technology; so there was no time machine; so you never entered it; so the murders never took place; so there was a time machine; which you entered....etc. etc. etc.

However, a physicist named David Deutsch explains how time travel could be logically possible in one of the chapters in his book, "The Fabric of Reality." This book, aimed at smart general readers, champions the multiple worlds interpretation of quantum mechanics.

Maybe you can travel back but by traveling back you can't return to the future because it hasn't happened yet.

Time is not real. It is a man made method to measure daily cycles and periodicity. Time has no substance. Quite literally there is only now. Our brains, in effort to distinguish events, recall things in a linear fashion.

Time travel is not possible for another more obvious reason.....people from the future would have been here by now, don't you think?
