The corridor of time does exist, but such a tour is trillion times riskier than a cruise in a basin with holes about the Pacific
A student from the Massachusetts Institute of Technology decided to organize a party and invited guests from the future, those who travel in time, to it. Guests may come in casual wear but must necessarily present evidences proving that they are not impostors. These may be medicines to cure AIDS or cancer, cold synthesis reactor or a thermonuclear reactor and things like this. Black hole
Modern science cannot give a definition of time. What is more, it cannot also prove that traveling in time is impossible. Anyone who goes for such a tour would inevitably grow older during the cruise according to the universal law of entropy growth. This is not a joke that meeting a grandchild of yours is quite possible according to the modern physics canons.
How can a human build a time machine? The recent sensational discoveries in the black holes sphere offers majority of opportunities for this purpose. Many of the discoveries have already won Nobel Prizes. Black holes are the vanguard of science, but it is not correct to believe that the existence of black holes is proved once and for all. Physics laws are symmetrical: if there is a black hole in which everything may drop but nothing can burst out from it, there must necessarily be a white hole into which nothing can fall but everything gets out of it. In other words, if one jumps into a black hole in one place he may jump out of a white hole in some other place. Does it sound crazy? According to Einstein's theory of relativity, there are solutions of this type. They are very instable, and a corridor from a black to a white hole may get closed because of slightest perturbations. This corridor does exist, but such a tour is trillion times riskier than a cruise in a basin with holes about the Pacific. Any physical body may be crushed in the center of a black hole.
The Director of Sternberg Astronomy Institute, the Russian Academy of Sciences, Anatoly Cherepaschuk, does not think the issue of traveling in time is too fantastic. On his way to the center of a black hole an astronaut will see his future and another universe disposed to our universe in the future. The astronaut would have to move quicker than the light speed to get into this universe some other way, which is impossible. Unfortunately, the astronaut will not be able to get back and tell what he saw in the future. He will not even go down in historical chronicles; outside spectators will always treat him as standing not further than the black hole verge.
Recently, some encouraging theories were developed to prove that some objects having no horizon of events exist in the powerful gravitational field; this allows traveling there and back in a time machine. American Kip Thorne and a member of the Russian Academy of Sciences, Igor Novikov, working in the west are connected with calculation of such objects. These objects are called mole burrows or space-time tunnels. Mole furrows are built of exotic vacuum-like material with negative pressure. In the tunnels, time goes back with respect to the outside space. Astronomers of the world dream of finding these mole furrows in the universe with the help of telescopes.
Many fiction authors described traveling into the past where people found the present-day world changed after the voyage because of their doings in the past. But physics theories state that these actions cannot be fulfilled with the help of a time machine: not only the past has an effect upon the future, but the future also influences the past. The cause-effect relations are very stable, and all events happen in such a way that they cannot be changed.
I don't think I've ever felt more stooopid than when I read that book...
Or that movie from 2037 - Honey I messed Up the Past
Actually AIDS didn't come about till the exploration of Titan and the encounter of saturian primates. Then a time traveller took it back to 1979 hoping that a cure would be found by 2101 when he catches it.

John Kerry might finally be able to go back and actually spend Christmas 1968 in Cambodia...
Yes! He could have a cup of wassail with Pol Pot.........
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....
Actually, that turns out to be an urban legend.
One bit I recall is that so many future viewers were tuned to the Crucifixion that they interfered with each other.
Yeah, yeah, I heard this same thing 30 years from now.
Issac Asimov wrote a good short story about exactly why you would NOT want to invent a time machine, or, as in his story a "Time Viewer". When does the past start? A century ago? A decade ago? Last week? Yesterday? One microsecond ago is a good start. If you could build a machine that just "views" time in the past, you'd have the perfect spying machine...................
Here's one from Science News -- this particular time machine isn't a machine per se, but once started in motion, would make it possible for future would-be time travelers to visit. Until the machine is set in motion, people in the future wouldn't be able to do so.

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 Einstein’s 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 Einstein’s 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.
