If you could never change anything or influence the Past/Future in case it disastrously effects your life, whats the point? Plus, if you're travelling to the future, how can you be sure not to end up inside a brick wall, or drowning in an ocean or the middle of a future highway you could never forsee?

I could travel back in time 20 years and warn myself not to marry my ex wife - and i could have smacked my ex best friend BEFORE he nailed my wife.
Oh and i'd now be the richest man alive courtesy of lots of big lottery wins ;)

Seriously? It would be a big deal. If nothing else we could go see historical events live - find out minor things like who was this Jesus person anyway, send back a Natural History team to make some cool documentaries on dinosaurs.
The problem is there's nothing in physics to say you couldn't alter the past. This has been used as 'proof' that time travel is impossible. However there is an interpretation of quantum mechanics that says the universe is constantly splitting up in to different timelines. If you went back in time and had your grandfather sterilised as a child you would still be standing there - but if you went in to the future your family would not exist - you would because you were from another universe. The only way to get in to those other timelines is at the branching point.
Scientifically the possibility of time machines is an open question, however I have read that one disappointing problem with them is that you would not be able to travel further back in time than when the time machine was created. There may be strange twists in space near blackholes we could use though if we really wanted to go shake hands with a T-Rex. I think if time travel was going to become possible somebody would have found a digital watch in a Roman burial mound by now.
Ps. Firefly? Stonehenge is an ancient solar calender that predicts with fairly impressive accuracy the equinoxes.

It would be so much better than reading how things happened in books, or seeing dramas about what we are told happened, to be there and see it for real, of course we couldn't affect their life because in their time we never existed, so as far as everything is in that time we don't exist.
Only the wonder of the future could affect us when we return from the future, because it is not possible to remember something which has not happened yet.
There need not be a problem as to where we are when we stop the time in the machine, because we could travel from an earlier period of our life, with some future for us in the time we are travelling from, so we must return to live that future.

True, but then you may not be able to alter the past - it could just be like watching a TV programme where you have no oppotunity to influence the events. And travelling to the future is easy - lock yourself in a cupboard for five minutes and then, when you climb out you're in the future! Hey presto!

you would probably build it in a secure location(i.e. a natural park )(something that has a low chance of being destroyed) if you could travel to the future the best advice would be to bring back their current thecnology that way when you do come back you can sell that AND improve society, if you were going in the past and COULD NOT change anything then just go for the fun of it

Actually, the main reason I'd want a time machine is to go back and smack my younger self around until I have more self-discipline.
Also, you could bring cool ancient artifacts directly from the source back to here.
And, you'd be able to know for sure whether disputed historical events actually happened.
There are infinite other uses for a time machine, you just gotta be creative.

All the lottery numbers for a year does not seem like a waste of time. An extremely good use of time hehe :D

Go back in time with the winning numbers to powerball, become the primary investor in Amazon, Ebay, Google, and Monster, then become an arrogant asshole!

We do not actually know the effects of time travel and/or how they can be manipulated. i myself have a theory. it basically states that in order for time travel to be possible we must have an infinite amount of energy (fact) and in order to have an infinte amount of energy we must have an infinte universe. but to have an infinite universe time itself must be infinite and there must have been in order for the universe to exist.
