Is time travel possible?

       Though it may of seemed decades ago that the years of time machines were in our grasps, the science behind these machines is not there. Time is the 4th dimension; it is physically impossible to move around in this dimension with the technology and knowledge we have today. But even if you believe we may obtain this knowledge in the future, then where are the time travelers today from the future? The access to time travel is not available. Although the first two chapters of the book are convincing, the question still arises on how you are supposed to achieve this time traveling state. So is time travel possible? No. It is not.
