i don't think so.
there are two views about time: Newtonian and Kantian. The former states thattie is absolute and real whereas Kant said it only exists becuase we humans perceive it.
I subscribe to the latter. If we had no memory, would there be time? Your view of the world would be like seeing a frame at a time off a film reel - what you see is the present, as you have no memory nothing hash change i.e. moved hence you cannot measure speed/time.
.... and as somebody already said, if time travel were possible, we would be innundated with tourists from the future.

both - back to see the dinosaurs and future say 10,000 or more years into the future to see how humans have evolved.

The reason we haven't seen tourists from the future is that....... Einstein said that speed was the key to time travel (theory of relativity etc) So if we fired a person's particles (okay not yet possible but way, way in the future it may possible) around something like the large hadron collider then time travel may be possible.
However, the machine would be large and the mechanics would be on the inside within a magnetic field, so it could not travel through time itself but would have to be available at the moment in time the traveler traveled to. Therefore you would only be able to travel back to the moment the machine was built and switched on..... But before anyone says I'm wrong can I point out the following.....
1. Its all supposition (and likely to stay so for a while yet)
2. I sell car spares for a living and only have C.S.E level 1 physics......
But hey just just thinking about this has made my brain work on a Sunday night

If time travel were possible, surely as others have said we would have been inundated with people going backwards and forwards to all different points in time. Each person who travelled would have some sort of effect on the past or future, meaning that there would be an almost infinite amount of outcomes for the course of history. History would be rewritten on a regular basis, and I can't see how that could work.
It can cook your brain thinking too deeply about this, but it would seem to me that if time travel were possible we would always have known about it.

If history was re-written, how would we know?

Its nearly always the small details that catch you out. Trying too hard to not do anything that may affect future events.I love these types of things and there are lots of these, smart enough to time travel but not smart enough not to get caught on a primitive movie camera...

I'd love to go back to certain periods in history, but if I saw something I could change or help avert from happening it would annoy me too much.
After all, thanks to the 'Grandfather Paradox' and so on, you would be changing history, potentially with consequences towards your own existence or with catastrophic results for others.
It's the old one of, if you were to, say, kill Hitler when it would have been easy to do, who is to say someone else considerably worse wouldn't have taken his place, therefore rewriting history with perhaps a far worse outcome?
No, no, send me to the future (although the bit about coming back could concern me). Either that, or send me back so far that nobody really knows what happened at the time much.

You just need a Stargate and a Solar Flare to travel in time.
Although the US Air Force may be rather reluctant to let you anywhere near it...

the more advanced rules of physics are quite delicate, and theoretical, it would take very little to send our scientific theories back to the bronze age, its why astro physicists who use string theory as opposed to quantum loop theory hate black holes, it throws the book out the window.
for a long time physicists thought E=mc2 was the governing rule for the whole universe, then neutron stars and singularity phenomenon came along, threw that out the window too. so everyone was back at square one.
hawkings theory regarding space and time are highly THEORETICAL and easily disproved or overturned, it only takes a miner discovery.
as for traveling in time, it is known as fact that space can be warped, its why NASA is working on a warp engine(look it up, good reading)(space and time are interwoven,hence the term "the fabric of space time")
it is a strong theory that with enough power you can fold space, and therefore time, now what would happen if you folded space back on itself......?
and vuala! reverse time travel!
(this is theoretical science just like hawkings just less published)

A while back i was thinking this could be a great premise for a film... fruitless experiments to send objects back or forward only seem to make them disappear... the funding runs out and the experiments stop. Then decades later, objects are being found where they really shouldn't be, eg. a wrist watch being dug out of a coal seam in yugoslavia. This makes the news and one of the younger members (now say, 80 years of age) of the original experiments recognises the watch. Turns out that one can travel through either space or time, but not both at the same time.... then i started trying to work out some maths... i travel one second into the future.... where does that put my lab? A quick google suggests the earth spins at 465 meters/second, so i'm going to end up around 465 meters away from my lab... but then the earth has also moved around the sun a bit, and all the solar system has moved a bit too... then my brain turned to jelly, just as it is doing now. Maybe crime fiction is more my league than SF?!?
