Is time travel theoretically possible?
Time travel is the concept of traveling forward and backward to different points in time, much as we do through space. Unsolved problems in physics: Is time travel theoretically possible? Is it practically possible? If so, what are we to make of the time travel paradoxes, such as going back in time and killing one’s own grandfather, etc.? Humans are in fact always traveling in time in a linear fashion, from the present to the immediate future, inexorably, until death. Some theories are predicated on the fact that we move forward in time, and both forward and backward in space. Since time and space have been shown to be intrinsically linked, travelling forwards and backwards through time is not a theoretical impossibility. Currently, traveling at speeds approaching the speed of light can cause time dilation, the effects of which cause the individual traveling to pass through time more slowly. From the perspective of the traveler, external time would be going much faster, causing the t
