Consider this. It is pretty much safe to say that no one has come back in time to visit us. This means that in the future of intelligent life, not a single being will ever travel backward in time to our time. If someone will ever travel to us in time and try to let us know about it, it would happen. The fact that this never will happen could be because a)no one develops the technology. I highly doubt this because of the growth of human knowledge (let's just keep this part of the discussion focused only on humans for now) is exponential. Look at the difference in technology from 1200-1300. Or even 1,000 B.C. to 1 A.D. And look at the difference between 1950-present. The more we learn, the faster we learn new information. It is probable that in the next 100 years, the new technology discovered will make the leaps and bounds of technology during our time look like nothing. We will probably be much more advanced. So at the rate we're going, if we survive just another few thousand years, think of how advanced we will be. And if we survive many more years then that, then wouldn't it be probable that we will discover the technology to travel forward and backward in time? We've already discovered that the closer towards the speed of light you travel, the more time slows down. Yes, there is always the chance that despite the technology time travel will always be impossible, but I doubt it. Is anything truly impossible?
The fact that no one will ever come backward in time to us could also mean b)that we decide not to find out how to travel backward in time because we think it would be a bad idea. I highly doubt this would be the reason, because humans are hungry for new information, and time travel has fascinated us for a long time. I am sure that we would try to find out how to do it.
It could also mean that c)we find out how to travel backward in time but we decide not to do it because it could change the future. I doubt this also. Once a new technology is discovered, it always becomes more available to the people as time passes. Take the airplane. In 1910, very few people owned one. During the present, many people do. The same goes for time travel. Eventually, many people will have the ability to travel through time. Even if we try to stop the average person from doing it, it is probable that sometime in the future some people would get their hands on whatever is necessary to travel to time. If this happens, then it is very probable that some idiot would decide to go back in time for whatever reason, just as there will always be some idiot that doesn't take all of his medicine for TB and it becomes drug-resistant.
The finaly reason that no one will ever visit us could be d)we are wiped out before we discover how to travel through time. Because there are billions of stars in just our galaxy and billions of galaxies in the universe, chances are that there is a lot of life out there, and some of it wouldn't be good. So, there is a gooed chance that some day, aliens will come and try to destroy us. Also, we are very stupid and there is a good chance we will destroy ourselves. And unfortunately, I have no reason to belive that reason d could not happen.
Just some food for thought.
