If time travel was possible, where are all the time travellers from the future? They would be everywhere.
HINT: Starbucks..........
Nah, there's probably certain periods in history that are more popular than others. Everyone would want to go back to the birth of Christ; no one would want to go back to the late 1970's.
Well, if a time traveller came from the future, he'd probably do something to change history. Get a bunch of time travellers going back in time, and eventually, one of them will change history so that the time machine isn't invented in the future. Then on the alternate time line, time machines are probably invented again, only to be not invented as there is further time travel and screwing with the time line.
Just to be hypothetical . . . what if the future only exists when we get there. So the time travel can only go into the past.
Sounds weird, but think of it this way. With some video games, even when you reach level 2, you can still play level 1 . . . but not level 3 until you achieve something. Maybe that's the way it will be with time travel . . . the past is level 1, the present level 2, and the future level 3. You can't actually get to the future until it naturally occurs and becomes the present.
I've always believed that you could not go back further in time than the day the time machine was invented.
Therefore, since there are no 'time' machines, there can be no 'travelers'.
"If time travel was possible, where are all the time travellers from the future? They would be everywhere."
Just saw a program on this on the Discovery Channel. Looks like time travelers enter a parallel universe so we wouldn't see them.
That's the classic question, but I think I have the answer: There are better times to visit.
Or another possibility is the world was conquered by Islam and we reverted to a society of camel herders too stupid to discover it.
We live in a time second - one-second that keeps "moving" forward. ( In fact, time is a solid, so it doesn't "move") Millions of time travelers could go back in time and keep missing our "second". ( Just kidding, but you asked!)

You can only go backwards in time to the moment the time machine was created. For obvious reasons.
someones got to invent it first...as soon as we do,
all the future folks will start visiting us.....
they can't do it until we do it! Get it????
This is real easy...
My guess, is that what is gonna change is the understanding
of physics will progress so that most of the suppositions we
have now will be proven to be impossible, and only a few
will be provable, and/or doable. (just a guess, however!)
So no flames from the past, present or future please.
The various extreme-physics concepts of time travel I've seen imply that you can't go back any further than the initial construction of the time machine....
Many theories involving the possibilty are premised in the concept of distorting or bending space/time e.g. a wormhole -in essence, a portal or carrier between two locations. The theories tend to favor informational "travel" being far easier to accomplish than physical travel and as such informational would be first realized. Anyway, as to travel between -both locations would have to be established prior to any possibility of transmission either way. Some of the theories hold that until a time "transceiver" is created and established in the "now" that the future has no location to come back to AND that the first time "transceiver" will enable a watershed of technological advance from the untapped infinity that entails future time/space.
In essence, your question is similar to asking where are the radio programs when we have no radios yet...
Research what Ronald Mallett is up to for further insight into this line of thinking:
Professor Predicts Human Time Travel This Century
Ronald Mallett, Professor at the University of Connecticut, has used Einsteins equations to design a time machine with circulating laser beams. While his team is still looking for funding, he hopes to build and test the device in the next 10 years.With a brilliant idea and equations based on Einsteins relativity theories, Ronald Mallett from the University of Connecticut has devised an experiment to observe a time traveling neutron in a circulating light beam. While his team still needs funding for the project, Mallett calculates that the possibility of time travel using this method could be verified within a decade.
