of course no

Yes and no.
Inventing a time machine is too generic. What do you want your machine to do? Travel back into the past? or forward into the future?
To answer either question you have to ask another question: does the past/future exist?
As far as I know, there is no place where the past is stored. And the existence of the future destroys the foundation of ethics (because you won't be responsible for anything you do).
Then you have to deal with the paradoxes that are associated with time travel. Famous ones include the Grandfather Paradox, where you go back in time kill your grandfather, and are left wondering how you could be alive, because your father wasn't even born (you just killed his father).
There is though one possible form of traveling into the future, but one that is impossible by current technological standards. In short, if you travel at nearly the speed of light, the passage of time almost stops, so while the rest of the universe is fighting wrinkles, you stay nearly unchanged (you don't grow old). When you stop traveling and rejoin the same time as the rest of the universe, you'll find that perhaps thousands of years have passed since you left, and you will have aged no more than a day. Maybe you can call that time travel. But unfortunately you're stuck in the future you get to, because time travel to the past is still simple impossible. But we've been surprised before. Who knows, maybe we will be again.

Inventing a machine to travel in time is easy. Making it work is the tough part.

YES! It involves restraining of gravity force and mastering some new laws of physics, but that will not be done in any near future. So, the real question is: When we'll build time machine? Or: Will we still be alive so we can make time machine?
Maybe Stephen Hawking has some clues to it...

Once there was a story about Einstein , ( I think a myth) where he and the navy had worked on a time machine . the idea was to move a boat thru time. the boat only half way disappeared. the guys on deck fell into the deck half way and were stuck in the deck and died. well the story was something like that .I'm sure some one know the whole story better then I .

Sure. Complex patterns of behavior arise out of the myriad interactions of simple agents, which may each operate according to a few simple rules. Just ask anyone, you could invent a time machine using simple interacting agents that operate according to simple rules. For instance, If you use your memory and your mind, you may just be able to time travel.

yes.
1) go out to your dumpster
2) find a cardboard box
3) write "time machine" on it (don't worry if you spell it wrong)
4) sit in the cardboard box and marvel as you travel into the future (it takes 1 hour in the box to travel 1 hour into the future)
on a more serious note, interactions are reversible on the microscale, but on the macroscale, where statistical mechanics come into play, it may be that we percieve the direction of entropy as the passage of time. so, no. unless you don't think the 2nd law holds.
there is also the thing about spacetime curvature around really big things rotating very quickly. but i don't understand that

No. Someone said past, present, and future are all happening NOW. As if there are different dimensions all around us. I believe that humans are capable of experiencing past and future by using their minds and not a machine. All of time exists now, its a matter of training your mind to be able to see it or tap into the universal consiousness. I believe this is what Edgar Casey was able to do and other pshycics as well.

yes, according to the theory of relativity by Albert Einstein it is possible to go in future but not in past. Suppose you are in Delhi than upward direction would not be same for you as in Mexico city. Upward direction is relative for with the your position. Similarly, time is also relative with the speed. If you move at a speed of 2,40,000 km/s than only 6 sec will pass for you but for others who are at rest 10 sec will pass. In a way you came 4 sec in future. If increase the speed this ratio wiil increase but only till the speed of light. Actually speed of light is the limiting velocity, nothing can go above that.

In time anything is possible. If you asked a person in 1850 if they thought that there would ever be an instantaneous way to communicate and ask questions to people all over the world what would they have said?

It is impossible to invent time machine.Because we have been made by God i.e. ALLAH.So everything is in His hands.....
Otherwise it is impossible because the time that has gone will never return.
